The electronic control system, electronic power optimizing system and working mode control system of the KOMATSU and DAEWOO diggers are introduced here. The principles and fault diagnosis of the automatic idle speed device, the electronic accelerograph and the engine electronic control system are discussed in detail. 简述小松、大宇等挖掘机电子控制系统、电子功率优化系统和工作模式控制系统,介绍自动怠速装置的原理及故障诊断,详细论述电子油门和发动机电子控制系统工作原理及故障诊断。
The behavior of engine automatic starting and stop under idle speed is an important working model for HEV ( hybrid electric vehicle ), which can avoid engine running under idle speed. So it can reduce engine fuel consumption, exhaust gas emission and wear efficiently. 发动机怠速自动起停是混合动力汽车的重要工作模式,它能避免发动机在怠速下运行,有效减少燃油消耗、尾气排放和发动机磨损。
