使用本步骤排除发动机超速故障,或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,请参阅故障诊断与排除, "事件代码"。 关于发动机监控系统的信息,请参阅故障诊断与排除, "发动机监控系统"。

注: 以下某些代码可能不适用于特定的应用。

表 1
故障诊断代码    
CDL 代码     J1939 代码     代码说明
(代码说明可能不同)    
注释    
E362(1)     190-15     发动机超速     记录该代码。    
E362(3)     190-0     发动机超速     此代码需要出厂密码才能清除。    

可能原因

  • 继续沿陡坡下行(如果适用)

  • 涡轮增压器的正常工作

  • 进气

  • 起动辅助装置工作异常

建议的措施

注: 下面以概率的先后顺序列出了这些步骤。 依次完成这些步骤。

表 2
故障诊断与排除测试步骤     数值     结果    

1. 继续沿陡坡下行(如果适用)

可能需要在陡坡上接合发动机制动器。

A. 使用发动机制动器时,操作员需要了解正确的机器操作方法。

并非所有应用场合都有发动机制动器。
   

陡坡
   

结果:陡坡是超速的原因所在。

控制陡坡上的发动机转速。

结果:陡坡不是超速的原因所在。

转至测试步骤 2。
   

2. 涡轮增压器的正常工作

A. 检查涡轮增压器是否正常工作。

B. 检查是否有任何机油漏入进气口中。
   

涡轮增压器
   

结果:涡轮增压器中的机油漏入进气口中。

修理或更换涡轮增压器。

结果:涡轮增压器中的机油没有漏入进气口中。

转至测试步骤 3。
   

3. 进气

A. 检查周围有无可燃气体。

B. 检查起动辅助装置(如果配备)是否正常工作。
   

空气质量
   

结果:大气中含有可燃气体。

不要在有可燃气体的环境中运转发动机。
   

按所列步骤顺序完成以上步骤。

以上步骤解决了此问题。 将发动机重新投入使用。

以上步骤没有解决问题。
