利用四缸火花点火发动机模型，实践基于dSPACE 实时仿真系统的具体实验方法， 判断控制器模型的优劣。其中包括基于MATLAB/Simulink 的闭环离线仿真实验, 创建ControlDesk 试验界面，完成应用程序的编译、连接，代码的生成及下载，调整PI 参数进行实时仿真实验。-The use of four-cylinder spark ignition engine model, and practice the system based on dSPACE real-time si

本程序本人在matlab环境中处理电控发动机中处理点火波形，方便分析点火波形从而诊断故障。-The procedure is designed by myself in the matlab environment to deal with electronically controlled engine ignition waveform, to facilitate analysis of the ignition waveform to diagnose the problem.

The easy availability, lower well-to-wheel emissions, and relative ease of use associated with existing engine technology have made ethanol and ethanol-gasoline blends a viable alternative to gasoline for spark-ignition (SI) engines. The lower energy
