电控汽油机初始MAP图的仿真计算

A Simulation Method of Getting the Original MAP of ElectronicControlled Gasoline Engine

本文介绍了一种获得电控汽油机初始 MAP图的新方法 .根据循环进气量确定喷油量 ,获得喷油脉宽控制 MAP图 ;根据点火模型确定点火提前角 MAP图 .为验证本方法的有效性 ,以 4 62 Q汽油机为例进行了配机实验 .实验结果表明 ,本方法是确定电控汽油机初始 MAP图的一种有效方法 .

In this paper, a new method to get the original control MAP of electroniccontrolled gasoline engine is presented. The fuel injection control MAP is obtained based on the intake air, and the ignition advance control MAP is obtained via the combustion model. Test results of the 462Q gasoline engine show that it is an effective way to abtain the original MAP of electronicalcontrolled gasoline engine.
