    Abstract

    With the strict implementation of the emission regulations, the pollution emission of lightvehicles in China has been effectively controlled, but the pollution emission of heavy vehicles isstill urgent to be solved, especially the large and frequent buses and buses, which have becomethe key factors for the emission of vehicle pollution in the city. The purpose of this research is toanalyze the effects of diesel and hybrids on emissions under different driving conditions.

    In this paper, the research progress on the driving conditions at home and abroad isinvestigated, the formation mechanism and the harm of the main exhaust emissions ofautomobile exhaust are understood, and four kinds of detection methods for automobile exhaustemission are summarized. After comparing and analyzing, chassis dynamometer and vehicleexhaust analysis system were selected as the main experimental equipment. The chassisdynamometer has good accuracy and stability. It will be an important testing instrument forheavy vehicle emission in the future. The exhaust emission of diesel vehicles and hybrid vehicleswas analyzed in the CCBC cycle, and the contribution degree to the vehicle emission wasstudied at the same speed, acceleration and idle speed. It was found that the sharing rate ofemission pollutants was the highest in acceleration condition, especially at high speed.

    Keywords: Driving condition;Emission of pollutants;Vehicle emission
