Abstract

Abstract: To solve the optimization of turbocharged diesel engine combustion and emissions performance for different EGR rate under different working conditions, the operation parameters of the diesel engine under different EGR rate was obtained through experiment at first; then the specific fuel consumption, NO_x, soot and cylinder pressure were selected as decision targets and the evaluation model for turbocharged diesel engine performance under different EGR rate was established based on multi-objective grey decision, finally optimum EGR scheme was achieved. A simulation platform for EGR performance evaluation was designed by MATLAB which simplifies the modeling process and improves the efficiency of simulation calculation. The effectiveness and practicability of the simulation model and platform are verified by an example and the study is valuable as reference for optimizing the EGR performance.
