摘要
从丰田1JZ-G发动机ECU实物上测绘出它的电源供电系统原理电路,讲述其常供电电路、主供电电路的工作过程。介绍丰田2TZ-FE发动机电控单元、丰田LEXES LS400轿车ABS电控单元、日产蓝鸟1.8L发动机电控单元的供电系统电路,以此为基础指出《汽车发动机控制单元电源供电系统分析与探讨》一文中存在的问题。
The author describes working process of the ordinary and major power supply circuits, taking the principle circuits mapped from TOYOTA IJZ-G engine ECU; introduces the power supply system circuits of ECUs for TOYOTA 2TZ-FE engine, ABS on LEXUS LS400 and NISSAN BLUEBIRD 1.8L engine; points out the problems existed in the article Discussion on Power Supply System for Engine Control Unit.
