电控发动机主要是依靠电子计算机技术控制发动机燃料供给系。根据电控喷射形式不同,分为:①机械式多点单独控制喷射;②机械式多点集中控制喷射;③电子式单点单独控制喷射;④电子式单点集中控制喷射;⑤电子式多点单独控制喷射;⑥电子式多点集中控制喷射。计算机还对点火时刻,怠速稳定,排放等进行控制,由于控制参数增多,传感器也相应增加,发生故障,很难查找。为了便于维修与保养,因此设计了计算机自我诊断系统。当讨算机采集的信号超出范围,即判断为该信号出现故障,这时ECU(电脑控制单元)立即做
Electronic control engine mainly relies on computer technology to control the engine fuel supply system. According to the different forms of electronic control injection, divided into: ① multi-point mechanical control jet alone; ② multi-point centralized control of mechanical jet; ③ electronic single-point single injection; ④ single-point electronically controlled injection; Point control injection alone; ⑥ electronic multi-point centralized control injection. The computer also controls the ignition timing, idling stability, emissions and other control, due to increased control parameters, the sensor also increases accordingly, failure, it is difficult to find. In order to facilitate the maintenance and repair, so the design of a computer self-diagnosis system. When the computer collects the signal beyond the scope of that signal is judged to be failure, then ECU (computer control unit) immediately
