使用本步骤诊断和排除进气歧管空气压力高故障,或者在下列任一事件代码为现行状态时使用本步骤。 关于事件代码的信息,请参考故障诊断与排除, "事件代码"。 必须进入 Caterpillar 电子技师(ET)上的发动机监控系统才能查看这些代码的当前触发点。 有关发动机监控系统的信息,请参考故障诊断与排除, "发动机监控系统"。

表 1
事件代码    
代码和描述     产生此代码的状况     系统响应    
E1044(1) 进气歧管压力高     进气岐管空气压力高于触发点已达到编程的延迟时间。     系统将会记录该代码。    
E1044(2) 进气歧管压力高     系统将会记录该代码。
发动机功率降低。

可能原因

  • 诊断代码

  • 进气和排气阻塞

  • 满负载设置(FLS)

建议的措施

诊断代码

使用 Cat ET 检查有无现行或记录的诊断代码。 在继续执行本步骤之前,诊断并排除所有现行代码。

进气和排气阻塞

  1. 检查空气滤清器有无损坏。 如有必要,更换损坏的空气滤清器。 请参考操作和保养手册。

  1. 检查进排气系统有无阻塞和/或漏气。 请参考系统操作/测试和调整。

满负载设置(FLS)

确认 FLS 正确。
