Selection and Match of Catalytic Converters Model for National VI Light Buses
ZHANG Chuanliang
Abstract: The selection and match of the catalytic converter model are important links to ensure that the en-tire vehicle meets the National Ⅵ emission standards. This paper takes the development of a light bus with National Ⅵ gasoline as an example. Through the model selection and match of the catalytic converter,calibration of the engine electric control system,and verification testing,the optimal scheme of National Ⅵ e-mission control is ultimately determined.
Key words：light bus; gasoline engine; national Ⅵ emission; catalytic converter
