Abstract :
A National IV standard SCR control system is installed on a National III standard diesel engine. After doing ESC test cycles for emission evaluation, we know the approximate transformative capacity and rule of NOx when exhausts pass the catalyst. A MATLAB/Simulink simulation model of SCR system is established. The conversion ratio in simulation and that in experiment are compared, and results show that the simulation module is reasonable.
