使用本步骤诊断和排除燃油供应系统故障,或者在以下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    
E1128(1) 燃油滤清器(吸油侧)进口压力高     燃油供应压力高于编程的触发点已达到编程的延迟时间。     系统将会记录该代码。    

可能原因

  • 燃油压力调节器(客户安装的部件)

  • 增压泵(客户安装的部件)

建议的措施

压力调节器

注: 这是由客户安装的部件。

检查燃油箱上的增压泵与燃油粗滤器进口之间有无燃油压力调节器。

如果存在调节器,则检查调节器出口处的燃油压力。 如果燃油压力不在技术规格范围内,则调整调节器。 如果怀疑调节器存在故障,则更换燃油压力调节器。

如果调节器没有安装在增压泵与燃油粗滤器进口之间的燃油供应回路中,则将一个燃油压力调节器安装到回路中。 调整燃油压力调节器,以便获得正确的燃油压力。

增压泵

注: 这是由客户安装的部件。

检查增压泵出口处的燃油压力。

如果增压泵的出口压力不在技术规格范围内,则检查增压泵有无故障。 如果增压泵正常,则将一个压力调节器安装到燃油供应回路中。 调整燃油压力调节器,以便获得正确的燃油压力。
