国六轻型客车的催化器选型及匹配

Selection and Match of Catalytic Converters Model for NationalⅥLight Buses

催化器的选型和匹配是确保整车满足国六排放标准的重要环节之一。本文以某国六汽油轻型客车开发为例,通过催化器的选型和匹配、发动机电控系统标定及验证测试,最终确定最优的国六排放控制方案。

The selection and match of the catalytic converter model are important links to ensure that the entire vehicle meets the NationalⅥemission standards.This paper takes the development of a light bus with NationalⅥgasoline 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 NationalⅥemission control is ultimately determined.
