CG137-08 and CG137-12 Industrial Engines Caterpillar


Engine Timing Does Not Match Programmed Timing

Usage:

CG137-08 FPL

可能原因

  • 配置参数设定

  • 基本正时

建议的措施

注: 如果故障现象只在某些工况下出现(高怠速、全负载和发动机工作温度),应在这些工况下测试发动机。 在其它状况下对故障现象进行故障诊断与排除可能给出误导的结果。

配置参数设定

核实第一期望正时和期望发动机正时偏置编程设定正确。 有关正确设置,请参阅系统操作, "系统配置参数"。

基本正时

确认基准正时正确。 各发动机起动期间,电子控制模块 (ECM) 自动标定基准正时。 有关额外信息,请参阅故障诊断与排除, "转速/正时"了解详情。
