用启发式优化控制方法控制柴油机排放量

A Method of Heuristic Optimum Control for Diesel Engine Emission Control

利用启发式智能优化控制方法建立了基于降低柴油机排放和油耗率的优化控制模型，并在一台卡车用高速直喷式柴油机上通过调节变截面涡轮开度和喷油定时实现了降低NOx排放量和油耗率的控制策略。

A optimum control model for the reduction of engine exhaust emission and fuel consump-tion has been set up by using a method of heuristic optimum control. It is used to adjust the ooening ofvariable geometry turbocharger(VGT) and control the fuel injection timing(FIT) of a high speed truck DIdiesel engine to realize the reduction of NOx emission and the control of fuel consumption.
