汽油机闭环反馈辅助控制系统解析

Engine Management System Control Strategy in Fault Overhaul Application

现代发动机电控系统属于微机控制系统,早期采用开环控制,现在大部分采用闭环控制。发动机电控系统可以控制燃油喷射、点火、怠速、排放、增压、进气、巡航等。文章详细介绍了发动机电控系统中两种闭环反馈辅助控制系统工作原理。

Modern engine control system belongs to a microcomputer control system, early adoption of open loop control, now most of the closed loop control. Engine electronic control system can control the fuel injection, ignition, idle, discharge, pressure, inlet, such as cruise. This paper introduces in detail the engine electronic control system in two kinds of closed loop feedback control system working principle.
