3126B Petroleum Engine Caterpillar


E100 Low Engine Oil Pressure Warning

Usage:

3126B Z2A
产生此代码的情况:

电子控制模块(ECM)检测到以下情况时:

  • 发动机至少已经运转了30秒钟。 一旦发动机转速与低怠速相差不超过50 rpm,这10秒钟的延迟就开始计时。

  • 发动机机油压力低于图1中的"警告(Warning)"线长达2秒钟。

触发水平     设定点(秒)     复位水平     复位时间    
更多有关信息,请参看图1。     2 秒(sec)    
70 kPa (10 psi)    
20 秒(sec)    

直到发动机转速已经连续30秒钟超过0 rpm 时,ECM才将作出反应动作。

系统响应:

ECM将会记录此警告。

  • 发动机润滑系统可能有问题。

测试步骤 1. 检查有无诊断编码

  1. 将卡特彼勒电子维修工具(ET)连接到维修工具接头上。

  1. 将发动机控制置于通电(ON)模式。 发动机应处于停机状态。

  1. 检查有无任何活动或记录诊断编码。

预期结果:

应无任何诊断编码出现。

结果:

  • 与预期结果一致 - 没有任何诊断编码出现。 进行步骤2。

  • 与预期结果不符 - 有诊断编码出现。

    修复: 纠正导致诊断编码出现的根源。 请参阅本手册"有故障编码出现时的故障诊断与排除"部分中的适当专题。确保修理后故障被排除。

    停止

测试步骤 2. 检查发动机机油油位

  1. 检查发动机机油油位。

预期结果:

发动机机油油位正常。

结果:

  • 与预期结果一致 - 发动机机油油位正常。

    修复: 请参阅测试与调整, "发动机机油压力 - 测试"。

    停止

  • 与预期结果不符 - 发动机机油油位低。

    修复: 添加发动机机油至正确油位。

    停止
