摘要
Abstract
For that the low temperature of WHTC test and the SCR is not easy to react,which will cause the problem of high NOx emission,and based on the calibration of the engine fuel system,we adopted the throttle and post treatment package and other technical measures to improve the engine exhaust temperature to achieve SCR catalyst reaction conditions and to reduce PM and NOx emission. The research results show that this engine ultimately achieves the limit requirements of WHTC emission regulations.关键词
