卡特彼勒330C型挖掘机配置CAT C-9型柴油机。该型柴油机采用液压电控单体式喷油器(HEUI)实现燃油喷射以及喷油量的精确控制,可使用电子技师(ET)对柴油机进行故障诊断。本文就CAT C-9型柴油机无法启动的原因及排除方法进行分析。1.电控系统故障(1)蓄电池柴油机启动时,若能听到启动机电磁阀的“嗒嗒”声及启动机齿轮与飞轮齿圈啮合声,但是柴油机不能达到启动转速,可判定是蓄电池电量不足。此时应检查电源开关是否接触不良,蓄电池接线柱与电缆有无松动或腐蚀现象,并
Cat 330C Excavator is equipped with CAT C-9 diesel engine. The diesel engine uses a hydraulically controlled single-body fuel injector (HEUI) for precise fuel injection and fuel injection control, allowing electronic technicians (ETs) to troubleshoot the diesel engine. This article analyzes the reasons why CAT C-9 diesel engine can not start and the remedies. 1. Electronic control system failure (1) battery diesel engine start, if you can hear the starter solenoid valve “rattling” sound and starter gears and flywheel gear meshing sound, but the diesel engine can not reach the start speed, can be determined Is the battery power shortage. At this time should check the power switch is bad, battery terminals and cables are loose or corroded, and
