Dynamic modelling and sensitivity analysis integrated LNT-pSCR system

Year: 2016

Type: article

Abstract: The nitrogen oxides (NOx) emitted from diesel engines become major issues. Exhausted gas recirculation (EGR), lean NOx trap (LNT), and selective catalytic reduction (SCR) are typical methods to reduce the NOx emission. With LNT-pSCR system, the performance can be improved and the occupied space can be reduced. In this paper, a modified dynamic model for LNT-pSCR system is constructed. Sensitivity analysis is also performed with the simulation result. It is shown that the proposed model is consistent with the existing studies and parameters related to mass balances have a priority to those related to energy balance in parameter estimation to simulate the total dynamic system.
