Abstract
Atmospheric environment is seriously threatened by the particulate matter and nitrogen oxide emissions of diesel vehicles in-use. Feasibility of the emission reduction technology and its application used in the China III diesel vehicles was studied, and an emission control device that meets the target vehicle according to the characteristics of vehicle operating conditions was designed. Furthermore, demonstration of emission treatment of particulate matter and nitrogen oxides in diesel vehicles was implemented. The working conditions and matching applicability between vehicles and after-treatment devices during actual road operation were analyzed, and results of emission reduction were counted. The research indicates that matched with the working conditions, the emission reduction technology for the diesel vehicles in-use can be effectively reduce pollutant emissions under actual road conditions and achieve continuous emission reduction effects.
