Pollutants In Vehicle Emissions Control

With the development of auto industry and the fast increase of the present quantity of vehicles, the town environment has been badly polluted by the vehicle emission. Vehicle emission control has aroused the high opinion of the world every state nation, and home and abroad correlation science and technology worker also expend the extremely great effort to this, and had been acquired valid fruit on new vehicle control. At the moment, become a significant job in the interest of better dominating the town atmospheric circulation quality to research that is in-use vehicle control.External experience makes known, to implement inspection and maintenance program of in-use vehicle is the most scientific and rightful and economy and valid method of in-use vehicle control. Domestic implementation I/M program yet is in moving phase, still have to carry on the scientific and systematical research, explores to be fit for the condition of domestic is I/M program.This paper was by means of analyzing the originating philosophy of the vehicle emission, researched the effect element and badness on theory and experiment; Being living on this base, and researched and compared several currently used in-use vehicle emission testing methods, proposing our country implements testing methods and the criterion that I/M program ought to adopt. Simultaneous this paper researched I/M program organization establishment to divide the work against the function, and opened up I/M database administration system. The system service capacity such as the increasing of data, inquiry and statistics, and the data transmissions be able to be carried on by means of the electric network, in order to attain the fast and dependable message mutually aim. These problems wholly are the key to guarantee I/M program implementation, and also are that our country implements I/M program to be badly in need of the problem that resolved. In addition, this paper estimated the amount of the vehicle emission in urban and forecasted the tendency in future. These researches are useful explore to our country's in-use vehicle emission control, and will become the base of the research in this aspect.
