Abstract

Abstract

In order to cleanse city air, reduce vehicle emission, the paper studied the exhaust emission characteristics of light gasoline vehicle by the emission test of acceleration simulation mode(ASM) for more than 3 000 used vehicles, analyzed the relationships of CO, HC, NO_x emission levels with vehicle driving distance and vehicle age, derived their tropic formulas. The results indicate that CO, HC, NO_x emission concentrations increase by 0.24~3.73 times with driving distance increase from 1.0×10⁵ km to 3.0×10⁵ km, CO, HC, NO_x emission concentrations increase by 1.7~2.0 times with vehicle age increase from 2 a to 10 a. The nonconformity ratios of CO, HC, NO_x emission are less than 10% when vehicle age is less than 4 a, but they are more than 20% when it is more than 10 a.
