Cold Emission Calibration Methodology using Dynamic Modeling

Abstract

Recent years, the regulation of emission and fuel consumption have been becoming stricter. On the other hand, additional devices of engine make the cold-start emission calibration more complicated. For these reasons it is difficult to optimize cold-start emission. In this paper, the new methodology of cold start emission calibration is proposed, and it is shown that cold-start emission behavior is simulated by dynamic modeling methodology and optimal engine operating condition from the start to the end of FTP 1st. hill is obtained by optimization using dynamic model.
