【摘要】 研制了一种多点汽油喷射微机自适应控制系统。该系统以发动机转速、节气门开度确定发动机的供油量，以转速信号作为反馈实现空燃比的自适应控制，能自动适应控制系统本身使用工况及其环境的变化，降低油耗或提高发动机的动力性。介绍了控制系统的控制方法、理论、设计和实验结果及其分析。更多还原

【Abstract】 A microcomputer adaptive control system for multi point gasoline injection engine developed by the authors is presented.Engine speed and throttle position are used to measure intake air mass.Engine speed is also taken as feedback signal for adaptive control.It can compensate for the change of the control system itself and the operating condition to achieve higher power output and lower fuel consumption.The control methods,the design of the system and the test results of the system are presented in this paper.更多还原
