In order to obtain kinetic parameters of SCR catalyst, targeted on the SCR catalyst of 6105AZLD diesel engine made by Weifang Huadong Diesel Engine Co.Ltd, the SCR catalyst model and kinetic parameters calibration model were established by using AVL BOOST and AVL Design Explorer. 13 SCR kinetic parameters of chemical reaction were calibrated by enetic algorithm. Results show that the kinetic parameters by simulation agreed well with those of the actual catalyst.
