摘要/Abstract

摘要： 为了解决增压柴油机不同工况不同EGR率下燃烧与排放优化问题,通过试验获取不同EGR率下柴油机的运行参数,选取燃油消耗率、NO_X、碳烟和缸内最高燃烧压力等指标为决策目标,建立了基于多目标灰色决策的增压柴油机EGR性能评估模型,进而决策出最优EGR方案。利用MATLAB设计了EGR性能评估仿真平台,简化了建模过程,提高了仿真计算效率。通过仿真实例表明了仿真模型及平台的有效性和实用性,对EGR性能的优化具有一定的参考价值。

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.

Key words: diesel engine, exhaust gas recirculation, multi-objective decision, performance evaluation
