Design and manufacture of automotive engines

As a result of increasing demand for environmental protection, many regional and national government departments have demonstrated rigorous environmental regulations, that have a great impact on the design and production technology of automobile engines, coupled with the technical progress of the motor itself, the engine. The development of petroleum specifications is changing with each passing day. The growth trend of international engine oil has continuously improved the quality requirements of lubricating oil, and also the specifications of motor oil have grown quickly.

At present, the world has formed two Big associations, the AC International Lubricant Standardization and Accreditation Committee represented by the USA and Japan, and the European Automobile Manufacturers Association of Europe. They have developed evaluation methods for motor oil specifications and requirements, and have different Focus. These specifications contribute the development of global lubricants, and whether they may be unified for the interest of the lubricant market.
Gasoline engine oil The gap between the United States and European gasoline engine oil development The driving force for the evolution of gasoline engine oil is chiefly to conserve natural resources and protect the environment. However, the United States and Europe have adopted different policies to promote fuel economy.
The US policy is to set the fuel market for manufacturers such as light trucks and passenger and freight vehicles. The maximum limit for fuel consumption is $50 per vehicle per vehicle. This strategy directly puts pressure on automakers. In Europe, the fuel-saving policy would be to collect fuel consumption tax. As an example, the French gas tax is 7 for the United Kingdom and the United States only imposes a huge burden on the owner of the large consumption tax, which indirectly transmits the strain to the car manufacturer. The fuel economy policy has a larger effect on the development of lubricants. Different tendencies have emerged in Europe and the United States due to different focus. Europe pays attention to the oil change period and also the oil change interval is continuously extended.

For instance, the recommended oil change period of the German Volkswagen is the newest standard specification. The oil change interval is 30. In the United States, on account of the emphasis on fuel economy, the antifriction performance of the petroleum is continuously improved. The mileage of gasoline for every liter of this American automobile fleet has increased from around the year to about 47. It may be seen that improving immunity reduction is directly linked to improving fuel economy.

The gap between the development tendency of lubricants in the USA and Europe has led to differences in the makeup of lubricants. Tables are compared with the composition of motor oil formulations in the United States and Europe. The program test was created to test the fuel economy of the following generation gas engine oil.
The second aging stage is equivalent to driving to evaluate fuel economy and fuel economy durability. From the gas and oil test, gas market is reduced together with the expansion of working hours, so the other key is fuel market durability. Likewise attributes and fuel economy assessment methods have also been created. The fuel market tested by this method also reduces with the expansion of working hours. Fuel market durability is also an important facet of the evolution of its specifications.
Gas engine oil growth trends The United States and Japan emphasize fuel market, while Europe pursues a longer oil change period. It is not likely that the United States and Japan will sacrifice fuel economy and allow Europe forfeit oil-changing periods. Whether petrol engine oil standards can be merged in the future remains to be further examined and negotiated.

The lead evolution of gasoline engine oils relies on greater fuel economy and greater fuel economy. Emission system security. Better high temperature deposition protection. Another driving factor is that the elimination of leaded gasoline in all tests. And use more new models of engines in the test. Compared with a functionality, the functioning of the table and specifications is rigorous.
The specification enhances the control the capacity of the smoke management, requires the dispersion ability to be good, and has certain requirements for the dispersant and the foundation oil, otherwise the operation requirements are not met. Another substantial improvement is the increased evaluation of valve train wear. It's the newest diesel engine oil saver in Europe for the essentials of the motor that meets the European emission standard. Its functionality and related bench test will be shown. The worldwide standard performance level of diesel oil is a starting point for establishing a global standard for diesel engine oil. The institution of a global benchmark for diesel engine oil is currently only potential and there has not been any substantial progress.

Conclusion Environmental regulations have come to be the biggest driving force for the development of motor oil. On account of the differences in energy conservation represented by the United States and Japan and Europe, the gasoline engine oil cannot achieve global uniform criteria. But for a variety of specifications, fuel market durability is the trick to the next generation of gasoline engine oil technology. Due to environmental regulations, the convergence of diesel engine layout makes Qiaohe closer to diesel engine oil specifications, also it's possible to set up a global benchmark.

By the way, If you need to buy some civic control arm, I recommend this website www.ytautoparts.com. It is a wholesale Chinese supplier and have many types of auto parts.
