【Abstract】 The ignition control of gasoline engine was implemented with a single chip microcomputer as the key component. The open loop and the adaptive methods were used to control the engine ignition. Under the economical operation condition, the change of engine speed is taken as the feed back signal to control the engine at its optimal ignition advance angle. The test results showed that the adaptive ignition control with speed feed back was feasible, it could improve control precision and response speed, as well as engine performance. The system structure, control principle, speed feedback method, adaptive control, experimental results and conclusions were presented in this paper.更多还原
