Car Emission Pollution Control Technology Policy Research

The paper begins with the analysis of the practicing situation of controlling vehicles emission pollution at home and abroad, sets focus on the researches of difficult points and existed problems on governing our vehicles in use emission by evaluating the situation of controlling car's emission pollution in every link such as our vehicles production , utilization, inspection and maintenance, research and makes inquiry into the explicit methods of controlling the vehicles in use emission, and analyzes the benefit and the harm. What's more the article demonstrates the practiced experience of abroad car inspection maintenance system(I/M system), aims to the fact that our national economy is rapidly developing now and the amount of vehicles is increasing, insists on the rule of improving and handling the relation of environment protection and using vehicles better, and reachs the purpose the amount of vehicles is increasing while the amount of vehicles emission pollution is not. Another according to the situation of our vehicles technology situation and emission level, the paper demonstrates the most adopted and the most effected method is carrying on the vehicles inspection maintenance system by analyzing the inherent relation of the environment of carrying on I/M system ., the practicing vehicles inspection maintenance system and I/M system ,also it verifying the effect by experiment. Last the article works out and suggests that set up our vehicles in use emission controlling(I/M) system.
