按照此步骤以对排气温度高进行故障诊断与排除。

可能原因

  • 诊断代码

  • 进排气系统

  • 喷油器

  • 后冷器(如果适用)

建议的措施

诊断代码

连接 Caterpillar 电子技师(ET)后检查有无激活和/或记录的诊断代码。 在继续进行此步骤之前,诊断并排除所有激活的诊断代码。

进排气系统

检查进气是否受阻和/或有无泄漏。 进气歧管温度升高一度,会使排气温度升高大约三度。 检查排气歧管与涡轮增压器之间有无泄漏。 检查排气是否受阻。

燃油喷油器

喷油过多的故障喷油器会提高排气温度。 连接 Cat ET 以确定是否存在喷油器电磁阀的诊断代码。 执行"喷油器电磁阀测试"。 观察 Cat ET 对喷油器电磁阀励磁。 执行"断缸测试"。 找出缺火气缸。 请参阅故障诊断与排除, "喷油器电磁阀 - 测试"。

后冷器(如果适用)

进气歧管压力正常,排气温度高的情况可能是由于后冷器芯的散热片阻塞造成的。

如果应用有后冷器,检查后冷器是否工作正常。 检查后冷器芯有无堵塞。
