Abstract :
The adsorption reduction mechanism and main chemical reactions were analyzed. After that, a Lean NOx Trap (LNT) model based on Simulink was constructed in this paper. Grounded on our calculation results, precisely control of the transition between rich and lean combustion mode was obtained. And also, the ratio of rich burn duration to lean burn duration had a significant effect on the NOx emissions of engines.
