G3520C and G3520E Generator Set Engines Caterpillar


Turbocharger Turbine Temperature Is Low

Usage:

G3520C B9P

可能原因

  • 轻负载下运转

  • 来自集成温度感测模块(ITSM)的诊断代码

  • 气缸排气口的温度低

  • 温度传感器有故障

  • 点火故障

  • 气缸压缩低

推荐的修理

检查是否缺火

低负载运转会造成低排气温度。发动机以低怠速或接近低怠速运转,以识别缺火的故障。

诊断和排除缺火的原因。 请参阅故障诊断与排除, "发动机缺火、运转粗暴或不稳定"。

检查有无集成温度感测模块(ITSM)的诊断代码

使用卡特彼勒电子技师(ET)检查与热电偶相关的诊断代码。诊断和排除代码起因。

检查气缸排气口的温度

观察可疑气缸排的排气口温度。

如果排气口温度明显地不同,确定排气口温度不同的原因。 根据需要进行修理。

检查可疑热电偶

发动机关停后,从热电偶观察涡轮增压器的温度。

当发动机正常运转时,相似位置的温度会以相似的速率降低。 这样,相似位置的温度是可比的。

如果发现温度有差异,用另一热电偶调换可疑热电偶。 如果热电偶继续有温度故障,更换热电偶。

如果在热电偶原来位置上继续有温度故障,查明温度低的原因。

检查与点火有关的诊断代码

使用卡特彼勒 ET 检查与点火系统有关的诊断代码。诊断与排除代码起因。

检查点火系统

检查可疑气缸排的点火系统零部件。 请参阅故障诊断与排除, "次级点火 - 测试"。

根据需要进行修理。

检查气缸压缩

测量可疑气缸排的气缸压力,以便检查与气缸压缩有关的问题。

如果发现压缩低,查明压缩低的原因。 根据需要进行修理。
