Abstract
With the increasing seriousness of environmental pollution, emissions regulations are being tightened and the design and manufacture of heavy duty diesel vehicles, diesel engine parts and post-processing systems cost more time and money. Virtual test bed can replace real engine and vehicle based on hardware-in-the-loop test system to deal with the vehicle development and calibration issues. In this paper, an exhaust aftertreatment system simulation model established method based on the AVL CRUISETM M of a diesel engine of China 6 applied to virtual calibration is presented. The results of thermal parameter, pressure parameter and emission parameter show that the model is of good quality and can be used in the research of virtual calibration development.
