燃烧反馈式汽油机微机控制系统

Microcomputer Control System of Combustion Feedback in a Gasoline Engine

作者开发了一种燃烧反馈式的单点汽油喷射和点火微机控制系统,该系统的主要特点是应用与燃烧直接相关的气缸压力作为反馈信号,采用一个气缸压力传感器对供油和点火提前角两个参数进行反馈控制以及采用了自适应控制方法。该系统具有结构简单、工作可靠、控制准确以及过渡工况响应迅速等优点,将其用于发动机能提高发动机的性能。

A microcomputer control system of combustion feedback for gasoline injection and ignition control is presented in this paper. The combustion pressure which directly reflects the combustion process is taken as the feedback signal in this system. The feedback control for two control parameters can be realized by using a pressure sensor and the adaptive control method is adopted. This system is simple in construction and reliable in work and also has the accuracy and the fast response in operation It can be used to improve the combustion process and the performance of the engine.
