What is automobile environmental protection?

Few people are clear on this concept. Please see below the contents and new trends of automobile environmental protection. The contents of automobile environmental protection are as follows:
 Automobile Noise: Automobile Noise means mainly the noise including engine work noise and noise generated by vibration and transmission by automobile during running. The current methods of evaluation and testing are mainly outside noise and inside noise. The light automobiles are required to be less than 85 db (A) to avoid noise pollution.
 Automobile Exhaust Gas Pollution: Automobile Exhaust Gas Pollution means mainly the exhaust gas discharged from the exhaust tube of the automobile engine. The component of the contaminant depends on the type of the automobile engine. Automobile Exhaust Gas Pollution is the main pollutant source of the automobile as well as one essential item in automobile environmental protection.
 Fuel Evaporation Pollution: Fuel Evaporation Pollution aims mainly at gasoline evaporation of gasoline vehicles. Since gasoline is a substance with extreme strong volatility and there are a large amount of components harmful to human body in its volatiles, the item of fuel volatiles control is added to the control of automobile environmental protection.
 Crankcase Pollution: Crankcase Pollution means the inflammable gas that is leaked from piston ring opening of the engine and not completely burnt in the crankcase of the engine. Since it contains components harmful to human body such as carbonic oxide (CO), exhaust gas in the engine crankcase is not allowed to be discharged to atmospheric environment.
With continuous development in economy, automobile becomes increasingly important, but the traditional automobile on petroleum fuel destroys the environment. This issue brings about wide concern of many people. How to cut down the emission of toxic gas from automobile? This is a complicated technical and social issue. The methods to solve this problem are as follows: first, government law and regulation and policy; second, maintenance and supervision in the link of engine use; third, advanced control technology actively adopted by manufacturers to improve the emission of toxic gas.
The new trends emerged in automobile environmental protection at present that deserve our consideration.
1. Law and regulation on automobile emission become increasingly strict.
2. The demand for environment from the society becomes higher and higher so that the associated effort from all works of life are required.
3. Hydrogen-powered automobile is about to be popular.
4. Emission control products are widely applied.
5. Check and control on automobile pollution are enhanced.
These new trends raise higher requirement to our manufacturers and the society. We will make unremitting effort for this and return a fresh world to people.
