The Basic Knowledge of Piston

Engineis like a car's "heart", but the piston can be understood as is the "center" of the engine. In addition to living in harsh working environment, it is the busiest one in the engine, constantly engaged from the bottom dead center to the TDC, suction, compression, workmanship, exhaust.... The interior design of the piston is emptying, more like a hat. The both ends of the hole are connected with thepiston pin, which connects the smaller head of the connecting rod, and the bigger one of the connecting rod is connected with the crankshaft. Under this assembly, the reciprocating motion of the piston is transformed into the circular one of the crankshaft.
There are three lines at eachpistonskirt, it is with the purpose of installing two gas rings and an oil ring, and the gas ring is top loading. In the assembly, the opening of two gas rings need to be stagger so that they have the sealed effect. The main role of the oil ring is to scrape the excess lubricating oil splashed on the cylinder wall. At present, the widely used material of the piston ring mainly has the high quality gray iron, ductile iron, alloy cast iron, etc.



In addition, due to the different position ofpiston ring, the surface treatment they use it is different, too. The external circular surface of the first piston ring is usually processed by chrome or spraying molybdenum, which the main function is to improve the lubrication and abradability of the piston ring. Other piston rings are mostly processed by tinning or phosphatization in order to improve its abrasion resistance.
If the piston ring is improperly installed or sealing is not good, it will cause that oil on the cylinder wall flow into the combustion chamber and burn together with the mixing gas, that is the phenomenon of burning oil. If the clearance between the piston ring andcylinderwall is too small or the piston ring was jammed in the ring groove for carbon deposition, the cylinder wall probably will be scratched when the piston is doing the reciprocating movement. Besides, it will form very deep grooves on the cylinder wall after a long time, which is often said that the " cylinder scoring " phenomenon. Cylinder wall with grooves, bad sealing, also can cause burning oil. Therefore, it should be regularly check the working condition of thepistonand ensure the operation of the engine in good condition.

How to Open an Auto Parts Store

Theauto partsretail industry enjoys resilience even during times of economic downturn. "As Americans buy fewer new cars, they are spending more to maintain existing vehicles." However. reports that the auto parts industry is highly concentrated in that the 50 largest companies generate about half of the industry's total revenue. Before you open an auto parts store, you must conduct thorough research of your market.
Step 1 Pick a location. As an auto parts retailer, location is important for the viability of your business. Determine the saturation ofauto parts storesin and around your prospective area of business. Research the nature of your potential buyers as well as their purchasing power. Your town's zoning commission can provide you with information on the latest mapping of your store location and the surrounding areas.


153 Front Axle


Step 2 Obtain the appropriate business license and permits. States have varying rules and regulations pertaining to business licensing, permits issuance and business registration. Generally, you must register your business and obtain a general business license. Because you are going tosell auto parts, you must file for a sales tax registration as well. If you are going to sellDFM auto parts, you might need to obtain a separate license, depending on your business location. For example, in Sacramento, California, and in Georgia, used auto parts retailers need a special business license and a used motor vehicle parts license, respectively. To find out which government agency processes registration and issues licenses and permits in your state, go to SBA.gov, click the "Starting & Managing a Business" pull-down menu and click "Search for Business Licenses and Permits." Your state business licensing agency should direct you to the appropriate agency for auto parts retailers in your locale.
Step 3 Hire cashiers and sales staff. The number you will need depends on the size of your store. Your sales staff must be familiar with, if not experts in, auto parts and the mechanics ofauto parts production. It helps if they have training in the repair and maintenance of vehicles.

The Risks Of Purchasing Used Auto Parts

When it comes to searching for variousauto partsfor imports, there are many different methods in which a person can find exactly what they need. Several of these methods are clean cut as well as genuine. On the other hand, some of the methods used to find auto parts for imports are downright risky; for example, purchasing secondhand parts from places such as scrapyards, auto repair shops, and salvage yards. Even more disturbing is the fact that most auto repair shops will place used parts into a vehicle rather than new ones, which will increase the chance of something going wrong with the vehicle sooner rather than later. This is a move that is done usually to allow the auto repair shop to save money. Here are a few of the risks associated with purchasingspare partsfor your import vehicle that you should make note of, courtesy of Southwest Imports Auto Parts.




PAST HISTORY

When it comes to purchasingauto parts onlinefor imports, it is extremely important to get familiar with the past history of the specific parts you are looking to purchase. For example, if you purchase used parts from a junkyard, there really is no surefire way to know whether or not it actually came from a car or something else. In addition, used parts generally are not under any kind of a warranty, meaning you will be forced to use them at your own risk.

UNRELIABILITY

As previously mentioned, used parts can also oftentimes be purchased from auto repair shops; however, these parts are usually kept in a big pile at the back of the shop. For example, imagine that you were looking to purchase a generator for your vehicle from your local auto repair shop - how would you know for sure that the generator will last for as long as you need it to? Chances are that parts purchased from auto repair shops do not work very well, as the risk is always there for them to either malfunction or stop working completely. While someauto parts supplierswill sometimes offer exchanges or refunds if used parts stop working, it's generally a good idea to avoid purchasing them altogether.

GETTING RIPPED OFF

Perhaps the biggest risk involved with purchasing used auto parts for imports is getting ripped off by the person or shop selling them. If you were to experience this, chances are you would be unable to ever find or track down the individual who sold the parts to you should something happen to them once you get them installed.
Whether the parts you purchase perform their jobs or not, the reality is that purchasing used auto parts for imports is downright risky. The best way to prevent this is to instead focus onpurchasing new partsthat will work for many years to come.

Three major opportunities of the auto parts industry

The first：the rapid development of domesticautomobile market

China has its own special national conditions, our income gap is larger than the countries’ which are powerful in automobile industry. The size of the income gap will play a vital role in the popular speed of durable consumer goods. The smaller the income gap is, the shorter the time of the popular speed takes, and vice versa.
The income gap is relatively bigger which determine the popular speed of car in China is relatively slower, thus China'sauto parts marketwill maintain a longer period of sustained growth, which also win a relatively long period of development for weak brand enterprises.



The second: accelerate the domestic automobile industry’s internationalization

During the twelfth five year period, the state will vigorously promote the internationalization of the automobile industry, and encourage theautomobile enterprisesto go out. But with international OEMs, it will also be a good pulling effect for China's independent parts enterprises.
Now the selling point of our automobile products match well with the demands of the consumers. At present, the world wide, South America is the fastest in the sales growth of auto products, South Korea, Japan and African market is also growing rapidly. However, the people in these countries pay more emphasis on the low price of automotive products. At the same time, with the country actively promoting the internationalized road ofautomobile industry, our country becoming auto power will also be just around the corner. So under such a background, auto parts enterprises will also usher in new developing opportunities.

The third: the rapid development of the independent automobile enterprise

China's auto market is undergoing a new change, that is the two or three line market, especially the three line market is becoming the main growth and support point of China'sauto parts developmentin the future. And consumers in three line of the market are not interested in foreign cars, instead, they pay more attention to economic applicability of automobile. Meanwhile, influenced by Chinese traditional thought, they have their own understanding about the appearance of the car. According to these characteristics, the independent brand cars has more developing advantage.
As the domestic independent brand enterprise is gradually strong, it will pull the rapid development of domesticauto parts industry. Domestic independent brand enterprises should grasp the opportunity and seek better development.

The Effect of the Automobile

    During the 1920s and 1930s the mass adoption of theCommercial Vehiclein the United States left few facets of everyday life untouched, and the young technology became deeply woven into the fabric of the country's economy, mobility patterns, and culture. As cities became larger and denser, industries increasingly sought cheap land on the urban periphery where they could erect the large, horizontally configured factories that mass production techniques necessitated. Wealthier urbanites, too, dispersed into out-lying suburban areas, closely trailed by retail stores seeking their patronage. Across rural America, larger trading areas hastened the death of the village general store, cut into small local banks' deposits, forced the mail-order houses to open suburban retail stores, and prompted the large-scale reorganization of both retail and wholesale trades, particularly as they fought to stay afloat during the Great Depression. Urban amenities, too, reached into formerly isolated rural areas, mostauto parts suppliersnotably in the form of far better medical care and consolidated schools. The Model T, the motor truck, and the motorized tractor also played a role in the reorganization of the agricultural sector as large-scale agribusiness began to replace the traditional family farm.



   Large-scale use of automobiles had a tremendous effect on the cities, too. Public health benefited as horses disappeared from cities; but street life became increasingly hazardous, especially for playing children, and automobile accidents became a major cause of deaths and permanent disabilities. Modern city planning and traffic engineering arose to meet growing traffic and parking problems; and attempts to accommodate the motorcar through longer blocks, wider streets, and narrower sidewalks strained municipal budgets even as they undercut the tax base by encouraging residential dispersal. Parents complained thatauto parts onlineundercut their authority by moving courtship from the living room into the rumble seat; police complained that getaway cars made it more difficult to catch crooks. Recreational activities changed, too, as the automobile vacation to the seashore or the mountains became institutionalized and as the Sunday golf game or drive became alternatives to church attendance, the family dinner, and a neighborhood stroll.
    By the mid-1920sauto parts manufacturerranked first in value of product and third in value of exports among American industries. The automobile industry had become the lifeblood of the petroleum, steel, plate glass, rubber, and lacquer industries, and the rise of many new small businesses, such as service stations and tourist accommodations, depended on the 26.7 millionmotor vehiclesregistered in the United States in 1929—one for every 4.5 persons—and the estimated 198 billion miles they traveled. Construction of streets and highways was the second largest item of governmental expenditure during the 1920s, accounting in 1929 alone for over $2.2 billion in road expenditures, financed in part by $849 million in special motor vehicle taxes, $431 million in gasoline taxes, and the steady expansion of the federal-aid road system that began dispersing funds in 1916.

Three focuses on the commercial vehicle industry market

1, Bargaining power of the Supplier 

    With the intensification of competition in the commercial vehicle industry , the profit of commercial product is more and more thin. At the same time, product cost controlling had become the essential rules of enterprise survival. However, the most important job of product cost controlling is to depress the purchasing cost of the raw material. The price competition between the supplier and the commercial vehicle production enterprises is also very fierce, the outcome of this competition depends on the strength of the supplier and production enterprises. Generally speaking, if the vehicle brand is better and more sales, then it can have a relatively greater pricing power; In turn, if the strength of suppliers is more powerful, product technology content is higher, the market share is bigger, then it will be dominant in price competition.
    Because the high-grade commercial vehicles are basically the product of foreign joint venture in China, the brand also is introduced from abroad, so the foreign parent company also become its suppliers inevitably. In this case, the bargaining power of producers become very weak, some foreign companies use the inequality relations between supply and demand to transfer price and eat the interests of the joint venture. From this perspective, some medium and low commercial vehicle enterprises in domestic have a relatively strong bargaining power.




2, Competitive strategy analysis for commercial vehicle products 

    Commercial vehicle really need to improve the level of technology in our country. But China is a developing country, not a higher technology is more effective. Joint venture enterprise doesn’t have to bring their most high-grade technology, it must combine with characteristics of China’s market, improve the technology of the existing brand vehicle and maintain an appropriate price, only then do the enterprise have the market competitiveness. Unsuccessful joint ventures often desperately engaged in technology transfer, spent a lot of cost and naturally must raise the price, so the outcome was that they lost the market.

3, Expectation of competition pattern for commercial vehicle industry 

     In some cooperation projects which is operated by Sino foreign joint venture, the cooperation model also undergo significant changes, that is from using foreign brands and producing foreign models to running Chinese brands jointly and entering the international market together. This kind of change is based on the current situation of China's commercial vehicle market, China's commercial vehicle market has distinctive demand characteristic and unique product structure, so foreign truck products are not suitable for the Chinese market at the present stage. On the other hand, in this round of joint venture cooperation, the foreign strategy is more flexible than before, but the China's right to speak is gradually enhanced.
     Due to the impact of the international financial crisis, many commercial vehicle enterprises are trying to find new developmental opportunities, and the consequent, the market pattern of the global commercial vehicle including China is quietly changed. In the process of rewriting the commercial vehicle’s market pattern, Chinese enterprises are facing the challenges as well as the opportunities. For the domestic commercial vehicle enterprises , although China is the world's the most important and most potential market, the inevitable outcome of the development is going out. Therefore, how to utilize the limited period of growth to form the independent research and development ability and complete sales network in overseas markets will become the top priority in the development of enterprises.

How to buy auto parts

1. See qualified spare parts surface appearance, print or type and legible and formal there are both certain accuracy and polished finish, the more important parts, precision is higher, more rigorous rustproof packaging. When the choose and buy if foundauto partswith rust spots or rubber parts cracked, loss of elasticity, or shaft neck surface has obvious tool lines, shall be returned.
2. The bad work product appearance although on occasion, but due to poor craftsmanship, prone to crack, sand holes, slag inclusion, burr or bruised. Such as cylinder gasket extrusion deformation, when using, easy to cause the untight seal and ablation, lead to the oil, gas leakage and leakage phenomenon.
3. See "loose" made up of two or more than two parts, accessories parts by being connected, bonding or between welding and become, not allowed to have loose phenomenon.
4. See assembly mark in order to ensure the parts assembly relations conforms to the technical requirements, with some regular parts surface marker assembly, such as timing gear, piston top marks, such as assembly mark, mark is used to ensure theauto parts suppliers, without a sign or mark fuzzy cannot recognize, will bring great difficulty to assembly, or even wrong.


5. See gaps complete formal assembly parts must be in good condition, to ensure smooth loading and normal operation. Some assembly of small parts packing, may be a "gray", to cause difficulties for loading. May even for some smallauto parts manufacturerparts shortage, cause the whole assembly parts scrap.
6. The protective layer for the purposes of custody, knock against, prevent parts have protectiveauto parts productionbefore delivery. Such as piston pin, bearing bush with paraffin wax protection; Piston ring and cylinder liner surface rust-proof oil and paper package; Valve, piston, etc after immersion rust-proof oil encapsulated with plastic bag. When the choose and buy, if find seal set of damage, loss of wrapping paper, rust-proof oil or paraffin loss, shall be returned.
7. The certificate some important components, especially the assembly class, such as carburetor, distributor, generators, etc., factory generally with manual, certificate of approval, to guide users to install, use and maintenance.
8. See most auto parts have stipulated specifications and technical parameters. Such as electrical equipment of choose and buy when, should pay attention to check and be inauto parts onlineof the voltage and power are consistent.

The relationship between the vehicle and the price of auto parts

At present, many factors which promote the price reduction of theauto partshave emerged. For example, the rapid growth in vehicle sales bring the auto parts’ mass production and domestic parts gradually replace imported parts, all of these will decrease in the cost of parts production. The entering of international manufacturers and other capital strengthen the accessories market competition and also promote the parts prices down. Unfortunately, the impact of the above factors are weaker than the vehicle manufacturers.Auto parts manufacturersmainly cooperate with the requirements of vehicle manufacturers, the price of auto parts in the 4S shop are mainly determined by vehicle manufacturers. When the vehicle manufacturers don’t feel the pressure from the consumer, they naturally won’t cut the price of spare parts.

clutch


So, why the consumer did not give the vehicle manufacturer with enough pressure? The reason is not complicated. The proportion that the buyer buy a new car for the first time is very high. These people lack the experience of the car, so the key consideration of purchase is the vehicle price, brand and appearance design. However, for the use of the car cost and the price ofspare parts, they pay little attention.
This is the case, the price of auto parts can down, but it is when, this will depend on the degree of consumer maturity and competition betweenvehicle manufacturers. When more and more consumers gradually rich the experience in the car, the attention to parts prices will gradually rise, too. At the same time, the fierce market competition will force the vehicle manufacturers to obtain competitive advantages from all aspects, at that time, the vehicle manufacturers will automatically cut the price of the auto parts.
The cost of buying a car is one-off defrayment, basically irreversible. But the cost of auto parts is uncertain, greedy and endless, so it must attract attention, especially, we should clearly understand this issue while we appeal against the extravagantprofits of auto parts. Study automotive repair and try to find some tips. on Based on the quality guarantee of maintenance, we spend less and cause less difficult. At the same time, when buying a car, it is important to note the supply situation of that car’s auto parts.

The characteristics of the international auto parts industry

1, The trend of the supporting system and modular supply is in the ascendant

The increasingly fierce market competition forces the change of the whole car system: purchase a single component to purchase the whole one.The system is not only beneficial to oems to make full use ofspare parts enterprisesprofessional advantage, but also can simplify the work and shorten the development cycle of new products. Parts suppliers must have a stronger technology development strength so that it can provide more system products and technology for the vehicle assembly plant. The more and more manufacturers are involved in the development and research of new products, its technical and economic strength is becoming more and more powerful.
On the basis of supporting system, biggerauto parts manufacturingenterprises put forward the concept of modular supply. The so-called module refers to the highly integrated and multi-function large parts which is formed by the arrangement of components and systems. In the modular supply, parts enterprises take up many development work of new products and technology. Not only in the product, but also in technology, Oems more and more depend on parts manufacturers, soauto parts onlinein the automotive industry has played more and more important position.



2,Procurement Globalization

Under the background of global integration, facing the increasingly fierce competition, in order to reduce costs, the world's major car companies expand the production scale while gradually reduce the self-making ratio of auto parts and use parts global sourcing strategy. Meanwhile, in order to obtain greater benefits, the international parts suppliers reduce or even stop the production which is un competitive advantage, lower value-added and technical content, they purchase comparative advantage products in the worldwide.

3, Accelerated the speed ofindustrial transfer

In Japan, Europe and the United States and other developed countries, relatively high labor costs result in lack of cost advantages in the production of auto parts products. In order to cope with the market competition, largeauto parts suppliersin Europe and the United States accelerated the speed of industrial transfer, countries such as China and India have become major destinations attracting the industry transfer of global auto parts.

Emerging Trends in Automotive Engineering

Not too many people knowautomotive trendsthe way the staff does at The Ohio State University's Center for Automotive Research (OSU CAR). This interdisciplinary research center at OSU's College of Engineering focuses on advanced electric propulsion and energy storage systems, engines and alternative fuels, intelligent transportation and vehicular communication systems, autonomous vehicles, vehicle chassis systems, and vehicle safety.
Other engineering trends focus on improving transmissions (adding speeds), accessory load reduction through the intelligent energy management of otherauto parts online, vehicle electrification, hybridization, improved battery management systems, new battery chemistries, and power electronics.
"Weight reduction in vehicle subsystems is also being tested by using lightweight structures made from alternative materials such as aluminum, magnesium, composites, plastics, and multi-material construction," adds Rizzoni.



Battery Systems

Battery management systemsare being designed to meet performance, life, and warranty goals for both batteries and their monitoring and management systems. "Automakers need to fully understand how varying operational limits affect the life of battery systems through extensive testing and modeling, followed by developing sophisticated algorithms to track and predict various parameters, such as state of charge and state of health through the life of the battery," comments Rizzoni.

Downsizing and Turbocharging

The two main benefits in downsizing an internal combustion engine are thermodynamic and mechanical. "From a thermodynamic point of view, the engine operation will move towards higher loads, at which the engine efficiency is higher," says Rizzoni. "From the mechanical point of view, the positive aspect lies in the reduction of the friction in the piston units, together with the reduction of the number ofauto parts manufacturer."
Downsized engines are lighter than conventional engines, thereby reducing vehicle mass and the improving vehicle fuel consumption. Turbocharging recovers the energy of the exhaust gasses to increase the inducted charge, therefore increasing the power-to-displacement ratio. "A downsized and turbocharged engine has the potential to have the same or better performance as a non-downsized, normally aspirated engine, with the advantage of a significant increase of fuel efficiency," says Rizzoni.

Advanced Combustion Modes

Engineers are working to increase the efficiency of internal combustion engines by developing severaladvanced combustion modes. One of these modes is called (homogeneous charge compression ignition) HCCI. In the HCCI combustion, a highly homogenized mixture of air, fuel, and combustion products from the previous cycle is auto-ignited by compression. "This combustion mode aims at combining the advantages of modern diesel and gasoline combustion processes, namely low emissions and high efficiency," states Rizzoni.
Another research trend targets ways to recover the energy that is normally dissipated through the coolant and the exhaust gas systems of automotive powertrains using innovative waste heat recovery devices. These systems can convert thermal energy into mechanical or electrical energy, thus increasing the overall efficiency of the vehicle. Organic Rankine cycle, thermoelectric systems, turbocompounding, and recuperative thermal management systems all have potential for significantly increase engine efficiencies.

Commercial Vehicle Insurance

No matter how big or small your business is or what industry you work in, chances are you use vehicles in your day-to-day operations. Whether it’s a single company car to get you around or a fleet of vehicles involved in multiple projects, in today’s competitive marketplace, vehicles drive business.

Unfortunately,commercial vehicle insurancecan often be complex and difficult to understand. Without this unique form of coverage, however, you could face financial losses that could seriously damage your company. With that in mind, here are five simple ways to tell if you need commercial vehicle insurance.

1. You Use Your Vehicle in aCommercial Capacity

The first question to ask yourself is whether or not your vehicle is being used for business. For example, if your vehicle is being used on a regular basis to carry equipment, deliver goods, transport people or provide a service (such as towing or snowplowing), you’ll need commercial vehicle insurance to properly protect you and your business.
That being said, different types of vehicles also require different types of commercial vehicle insurance. A taxi for example, would have different requirements than a vehicle used by a sales person, and a long-haul truck may also require some additional form of transportation insurance. The best way to be certain that you have the right type of commercial vehicle insurance is to speak with your broker and see what options are available.



2. You OperateMultiple Vehiclesfor Your Business

If you operate four or more vehicles in support of your business, you may want to consider a specialized type of commercial vehicle insurance known as Fleet Insurance. This type of coverage tends to cost less than individually ensuring each vehicle and often provides a single policy that covers multiple vehicles (making administration and renewal much easier).
Fleet Insurance also allows you to maintain multiple employee drivers, allowing you to have a flexible commercial vehicle insurance policy that can meet the demands of your business.

3. Employees Drive Your Vehicle

If employees (or anyone else associated with your business) drives your vehicle, then you’ll definitely need some form of commercial vehicle insurance in place. As mentioned earlier, Fleet Insurance allows you to haveauto parts supplieras drivers of your vehicles, but you can also customize your policy to select only a few key personnel.
Regardless of what specific type of policy you choose, if any employees are operating your vehicle, then you’ll need some form of commercial vehicle insurance to protect you from any financial damages that might result from an accident.

4. Your Business Could Suffer as a Result of aVehicle Accident

Two of the biggest risks you could face as a business owner are incorrect coverage or insufficient limits of coverage. In the case of incorrect coverage, you could be sued if you’re operating your vehicle for a business but only have personal automobile insurance. In the case of insufficient limits, the type of commercial vehicle insurance you have may not be enough to cover the full financial extent of the damages.
In either case, if the amount of potential financial damages could cause irreparable harm to your company, you should immediately speak with your broker to find the right type of commercial vehicle insurance.
As a general rule when looking for commercial vehicle insurance, you’ll want to make sure you have a knowledgeable team of insurance brokers who will understand your business’ specific needs. Additionally, a qualified insurance broker can help implement a risk management program to help eliminate potential problems before they occur. Most importantly though, having the rightcommercial vehicleinsurance in place means that you can spend more time focusing on your business and less time worrying about what might happen on the road.

Key points for the development of auto parts industry

1, Increase the development of key parts and technology and improve the added value of the product.

One of the main advantages of China'sauto parts exportsis the low labor costs. However, in 2010, the majority of provinces and cities have increased the minimum salary standard, our employment costs are gradually improving, auto parts products in the price advantage is diminishing. Therefore, only increase investment in product development funds, strengthen the development of key components and technology, improve the technology and added value of auto parts products, can we obtain greater profit space.

2, Vigorously develop new markets while continually consolidate the traditional market.

Our country always encourages theauto parts enterprisesto expand foreign market and introduces a series of supportive policies. In such aspects as finance and export credit, the country gives strong support for national auto parts export enterprises and export bases, so domestic auto parts export enterprises should grasp the opportunity. They should strengthen the traditional vehicle markets in developing countries, at the same time, increase the market development in India, Brazil and Russia and try to occupy foreign markets and the middling and high level market of developing countries.



3, Attaches great importance to the e-commerce, reduce thetrade cost.

As we all know, e-commerce business not only can save a significant reduction in manpower, material resources, reduce transaction costs and inventory, but also it can create a free and equal competition environment and a wider space of cooperation for small and medium-sized auto parts export enterprises to enter the international market, so all of auto parts export enterprises should grasp this new business opportunities.

4, Reasonably setauto parts export priceand avoid vicious competition.

At present, some domesticauto parts productionenterprises are eager to open the international market and often quoted prices far below the international average price. In fact, this is definitely not a wise move: First, the very low profit margin is not conducive to long-term development of enterprises; Second, in the eyes of some large companies, not the lower the price, the better it is. They maybe think the product quality without a reasonable margin will be greatly reduced. Therefore, in order to avoid the adverse consequences caused by disorderly quotation, domestic manufacturers must first grasp the international market before the quotation. In addition, the auto industry association should also organize auto parts export enterprises price self-discipline and against vicious competition.

The development trend of auto parts

Auto parts productionis the basis of vehicle production. without a powerful component industry as a support, the automotive industry must be vulnerable. Global parts enterprises correspond with the oems. The development scale of auto parts industry is not only related to whether we can keep up with the pace of world, but also related to the orientation of the development of automobile industry, so the development mode will undoubtedly play a crucial role.

1, Theindependent brandandinnovation

As the basis of automobile industry, auto parts is the essential factor to support sustained and healthy development of automobile industry. Especially in the currentautomotive industryare vigorous to carry out independent development and innovation, so the strong system for support becomes more impendency. Vehicle independent brands and technology innovation need spare parts as a basis, however, the independent innovation produces impetus for the development of vehicle industry. They are mutual influence and interaction.

2, Establish the idea ofglobal competition

The industry pattern of the world car industry is undergoing change. With the new round of the merger and reorganization, vehicle andauto partsoligopoly has been significantly appears. It has become the consensus that the vehicle and parts enterprises should form the idea of both competition and cooperation. Global sourcing, which is based on "best procurement principles", is becoming widely used in vehicle business. In the future, the specialization of the vehicle and parts enterprises will be more clear, namely the automobile enterprise is engaged in vehicle design, assembly and brand; Parts enterprises are responsible for modular, systematic design and manufacture. Therefore, our parts industry must establish the idea of facing global competition idea and comply with the trend of world auto development.

3, Gradually form theinterests’ communityof the vehicle and parts enterprises

In the development process of the automotive industry, vehicle and auto parts enterprises is actually a interests’ community. The strong brand of automobile enterprise depends onspare partsbusiness which should have advanced technology and management, reliable quality and reasonable cost; At the same time, the sale of vehicle provides a stable market for the auto parts enterprise. Therefore, this is a coexistence relationship between them. Only advance together, they can win common development.

Emerging Trends in Automotive Engineering

Not too many people knowautomotive trendsthe way the staff does at The Ohio State University's Center for Automotive Research (OSU CAR). This interdisciplinary research center at OSU's College of Engineering focuses on advanced electric propulsion and energy storage systems, engines and alternative fuels, intelligent transportation and vehicular communication systems, autonomous vehicles, vehicle chassis systems, and vehicle safety.
Otherengineering trendsfocus on improving transmissions (adding speeds), accessory load reduction through the intelligent energy management of other vehicle components, vehicle electrification, hybridization, improved battery management systems, new battery chemistries, and power electronics.
"Weight reduction in vehicle subsystems is also being tested by using lightweight structures made from alternative materials such as aluminum, magnesium, composites, plastics, and multi-material construction," adds Rizzoni.




Battery Systems
Battery management systems are being designed to meet performance, life, and warranty goals for both batteries and their monitoring and management systems. "Automakers need to fully understand how varying operational limits affect the life of battery systems through extensive testing and modeling, followed by developing sophisticated algorithms to track and predict various parameters, such as state of charge and state of health through the life of the battery," comments Rizzoni.

Downsizing and Turbocharging
The two main benefits in downsizing an internalcombustion engineare thermodynamic and mechanical. "From a thermodynamic point of view, the engine operation will move towards higher loads, at which the engine efficiency is higher," says Rizzoni. "From the mechanical point of view, the positive aspect lies in the reduction of the friction in the piston units, together with the reduction of the number of cylinders."
Downsized engines are lighter than conventional engines, thereby reducing vehicle mass and the improving vehicle fuel consumption. Turbocharging recovers the energy of the exhaust gasses to increase the inducted charge, therefore increasing the power-to-displacement ratio. "A downsized and turbocharged engine has the potential to have the same or better performance as a non-downsized, normally aspirated engine, with the advantage of a significant increase of fuel efficiency," says Rizzoni.

Advanced Combustion Modes
Engineers are working to increase the efficiency of internal combustion engines by developing several advanced combustion modes. One of these modes is called (homogeneous charge compression ignition) HCCI. In the HCCI combustion, a highly homogenized mixture of air, fuel, and combustion products from the previous cycle is auto-ignited by compression. "This combustion mode aims at combining the advantages of modern diesel and gasoline combustion processes, namely low emissions and high efficiency," states Rizzoni.
Another research trend targets ways to recover the energy that is normally dissipated through the coolant and the exhaust gas systems of automotive powertrains using innovative waste heat recovery devices. These systems can convert thermal energy intoauto parts onlineor electrical energy, thus increasing the overall efficiency of the vehicle. Organic Rankine cycle, thermoelectric systems, turbocompounding, and recuperative thermal management systems all have potential for significantly increase engine efficiencies. A smaller but still significant aspect of fuel-efficiency research is called "intelligent energy management." "This ability to more intelligently control the accessory loads in aCommercial Vehicle—such as the alternator or power steering, etc.—will also contribute to better gas mileage," says Rizzoni. "With smarter control of these loads and the addition of stop-start technology there can be significant increases in fuel economy, with small or no increase in total vehicle cost."

Basic knowledge of engine maintenance

Engine is the power source of the car, also is the heart of the car. It can effect the car’s performance, fuel economy and environmental protection. So, it is very crucial to keep the car’sengine maintenance.
Automobile engineis a higher value of mechanical products, so in the long-term use of the automobile, it inevitably occurs malfunction and damage. the basic task of engine maintenance is to adopt the corresponding technical measures to prevent the happening of the fault and avoid the damage of the parts. However, the basic task of theengine repairis excluding the fault and repair or replace the damaged parts so that the working ability and good condition of engine can be restored.
Engine is a component of automobile, so the basic requirements and methods of engine and vehicle maintenance are consistent.




1, The type ofengine maintenance

According to their nature, engine maintenance can be divided into preventive maintenance and non-preventive maintenance.
Preventive maintenance refers to the content and timing of the maintenance. According to the predetermined plan, its purpose is to prevent faults and maintain the working ability of the engine . Preventive maintenance also can be divided into routine maintenance and plan maintenance. For the routine maintenance, it is not the business of the car mileage, but it is the one of the plan maintenance.
Non-preventive maintenance is usually carried out in the engine maintenance after the failure. Inauto partsuse, the sudden fault has great randomness, it is very difficult to predict before a failure occurs, so it is impossible to maintain a pre-arranged plan.

2,The mode of engine maintenance

The mode of engine maintenance is a comprehensive embodiment of the maintenance's type, timing and content. Generally, it can be divided into regular, on-demand and afterwards.

3, The cycle of engine maintenance

The cycle ofengine maintenancerefers to the maintenance interval, generally based on vehicle mileage.
In a word, mainly engine maintenance is to keep the engine in a good technical condition so that it can prolong its service life.

How to make automobile parts to get a better development

1,Enterprise reorganization

The world's major car companies have supply system reform, they implement the global production and global sourcing. that is multiple auto parts manufacturers purchase into the supplier purchase system for the minority; a single steam car parts purchasing into a module purchasing ;the implementation of domestic procurement into global sourcing. The reform ofvehicle purchase systemshould fit with auto parts’ manufacturers constantly.Automobile spare partsmanufacturing enterprises not only require to widen their strength, improve the ability of product development, system development, system supply, but also to shorten the development cycle and provide quality cheap products.


2,Mergerandreorganization, overseas mergers and acquisitions will speed up step by step


The increasing fierce price war of whole car market is nibbling the profit margins of parts industry, At the same time, the demand of reducing costs and ensuring profits have become increasingly harsh. However, the output value of China's autoauto parts industryis large in scale, but there isn’t scale effect, so the integration and restructuring of the auto parts industry is imperative.

3,Market concentrationis higher which it will appear the development of supply chain

Market concentration is higher, OEMs increasingly tend to be modular and systematic procurement. The collaboration of suppliers is more closer, which it makes the supplier system of global automotive parts evolves to the pagoda type structure. At last, the manufacturer responsible for supply chain management will make the cooperation of supply chain become more standardized.

4,Operation globalization

In order to reduce costs and occupy the market, many automotive multinational companies have the ideas of operation globalization. Europeanauto parts productionenterprises invest overseas to make the international development; North American auto parts manufacturers are invested in Europe, which would also like to expand in eastern Europe market; Japanese car companies also continue to establish their own branch on a global scale. Emerging Asia is a major focus of automotive Multi-National Corporation competition. China is the battleground.

For thedevelopment direction of China's auto parts, the 12th five-year plan putted forward that auto parts is one of the four big development, the key problem is to improve the capacity for independent innovation so that we can achieve the breakthrough in key assembly technology and electronic technology 。

The knowledge of Cylinder head and Camshaft

Cylinder blockis the main part of the engine which will contact each of cylinder and crankcase into a whole. At the same time, it is the supporting frame of installing piston, crankshaft and other parts.

Cylinder headis bolted to the top of the machine body and becomes the top part of diesel engine. Its functions are as follows:

1,Close the top of the cylinder sleeve; form a sealed cylinder working space with piston and cylinder sleeve.

2,The cylinder sleeve is pressed in the correct position so that thepistonoperates normally.

3,Install all kinds of diesel engine accessories. such as injection valve, intake & exhaust valve, cylinder starting valve, indicator valve, safety valves and valve rocker arm device etc.

4,Arrange intake & exhaust, cooling channel. etc.In the small high-speed machine ofcylinder sleeveis also decorated with swirl chamber or precombustion chamber, so the hole and channel in the cylinder sleeve is various and make its structure more complex shapes.

camshaft


Camshaft is a part of the piston in the engine, its main body is a cylindrical rod which has the same length with cylinder group. its top have a plurality of cam, used to drive the valve. One end of thecamshaftis bearing support and the other end is connected to the drive wheels, that its role is to control the valve opening and closing action. because movement characteristics of the valve is related to the power and running properties of an engine, camshaft design occupies a very important position in the design process of engine.
