Guidance for Calibration of Air Mass Flow Correction in Vehicle
After the implementation of new emission regulations,competition in the diesel engine market has become increasingly fierce,requiring manufacturers to quickly adapt to market changes,shorten calibration cy-cles,improve efficiency.Regarding the current adaptation situation of diesel engines,one engine model usually adapts to multiple vehicle models,and the difference of the intake system at the vehicle can cause changes in the vehicle's emission performance,which is an important issue currently existing.This article focuses on the issue of air mass flow differences caused by different intake systems,then solutions are proposed to help calibration engi-neers quickly understand the importance of vehicle air mass flow calibration during the calibration process.It has certain guiding significance for vehicle calibration work.
