摘要
本文介绍了作者研制的ＪＬ４６２Ｑ汽油机集中控制系统。该系统用一个ＥＣＵ可同时对燃油喷射、电子点火及怠速转速进行控制。试验结果表明，采用该控制系统后，ＪＬ４６２Ｑ汽油机的动力性、经济性及排放指标均得到了明显的改善。文中较为详细地介绍了各功能的控制原理及方法，最佳ＭＡＰ图的制取，并给出了试验结果。
In this paper, the integrated control system of JL462Q gasoline engine was introduced. In this system, with only one ECU, the fuel injection, electronic ignition and idling speed were controlled simultaneously. The test results showed that with the help of this system, the power performance, fuel economy and exhaust emissions of the engine were improved obviously. In this paper the control principle and control method of every function, and the way to make the control MAP were discussed in detail. Test results were also illustrated.
