Research On Statistical Character Of Vehicle Emission

This essay mainly discusses exhaust emission spreading in air, effect to people抯 health and global environment, on the basis, Probes into the principle of emission produces development and present situation of emission pollution controls, put forward the main purpose and significance of this subject. Particularly produces the statute and technique policy on emission pollution, along with the testing technique and experiment method of emission in our country0 Over 3000 investigate data are measured Taking out 2000 and proceed statistics analysis with them, using methods of linearity regression equation and error square analysis investigated the diversification rules on the service life of the vehicle and diver mileage, obtained the analysis value and reduce rule, fixed the reduce coefficient. According to the statistical analysis result, the mean value of emission pollutants from 鄐ing automobiles does not exceed the present standards However, Our standard quota of exhaust emission is only equal to the level of Europe in 1970? Therefore, the rules of emission should be strict and the emission control can be done better, Suggested that we should strengthen the emission law, at the same time, intensify the management to present situation of vehicle exhaust emission.
