| Abstract: | In view of light off temperature characteristics of catalytic converter,this paper analyzes and studies the emission performance of vehicles on road,based on the features of inlet temperature/outlet temperature distribution of catalytic converter for the specific vehicle model and road condition(Tianjin) Through simulation on chassis dynamometer,the emission of vehicle is measured and compared with the result of ECE 15 cycle test It is shown that the pollutant emission in road condition is more than that in lab test |
