Abstract The tasks and demands of reducing gasoline vehicle emission and improving atmosphere environment for the government and automobile industries an indicated .The technology for reducing gasoline vehicle exhaust emissions and development and application of the catalytic converter systems are analyzed .

Key words Automobile, Internal combustion engine,Exhaust emissions, Emission control

1 Introduction

The development of the car industry, on the one hand, for human society Economic development provides a convenient condition, on the other hand car waste Gas for human survival environment has also brought the increasingly serious Harm. The modern automobile development technology target from users Consider, first is safety, comfort and economy. From the ring The perspective, some of these requirements and low emission method Rules and policies of contradictory. This means that the human to steam

Car emission control technologies of performance requirements in government (environmental protection) departmentDoor and in automobile industry development is shown on this problem outThe contradiction and mutual coordination.

2 Environmental protection and of the development of automobile industry coordination

In order to control the car emissions, since the early 70 s on the world to create the automobile exhaust emission regulations (government departments door)，After constant improvement and correction, regulations become more and more strictly. Table 1 list Europe and the us federal government auto emissions regulations of the development process. In fact, sure car exhaust emission regulations limit is not difficult, but the problem is, in order to meet the requirements of the regulations, the auto industry into human, material and financial resources is countless. In addition, the development cycle usually need three to five years. Therefore, in the formulation and implementation of foreign auto emissions regulations, will the next round of the implementation of the regulations time and content, reported that in advance

The auto industry has enough time to take appropriate measures. Therefore in the implementation of laws and regulations will not appear regulations and implementation of the auto industry production and development of the conflict.

Recently, some place in domestic enacted or promulgated and implemented new auto emissions standards,The relevant departments of the state in the new national standard also specified.The focus of the discussion on these standards is to carry out fixed number of year. From the Angle of environmental protection, in order to and the international community, the implementation of the car as soon as possible strict emissions standards is imperative. But must leave room for the auto industry. Past due to various reasons, even make national standards, in fact no strict enforcement. On the other hand, formulate standards must also have a "advance", can't make the automotive industry.

Improve the quality of atmospheric environment is a global problem, from auto industry to see, it is necessary to put into the corresponding human, material and financial resources to reduce vehicle exhaust emissions. If hold fluky psychology the, then, will eventually be out by the market.

3 Reduce automobile exhaust emission pollution may way

Reduce exhaust of atmosphere pollution can be from the following two aspects.

（1）Reduce pollution emissions

Reduce emissions is to reduce pollution and automobile exhaust emission, here related to:

a.Auto technology. In addition to the engine technology, also related to power automobiles transmission system optimization, and the vehicle technology.

b. The road traffic planning and design. Rational planning road, ensure good traffic road conditions and sparse traffic density, reduce automobile engines in idle speed and low load, so can reduce running time of the auto emissions;

c. The car driving conditions. Car in off-design conditions (acceleration, slowing down, idle speed) and emission performance in relatively poor working conditions, the operation will greatly increase emissions. Here except and road traffic factors outside, and drivers driving habits have closely contact;

d. Repair and maintenance. The heavy-duty automobile repair and maintenance is to guarantee the low pollution, one of the important measures.

（2）Improve the diffusion and absorption in environment

Here the term car emissions (exhaust, fuel evaporation, the crankcase ventilation, etc) in the atmosphere spread. It involves:

a.The geographical environment, such as location, wind power, wind, temperature and light, etc;

b. The overall plan of the city, such as city buildings, green, etc.

This shows, reduce automobile emissions is not only the auto industry and the environmental protection department, still with the vehicle manag …… 此处隐藏：14444字，全部文档内容请下载后查看。喜欢就下载吧 ……
