E005 Fuel Filter Restriction Derate
产生此代码的情况:
发动机已经运转 60 秒钟，并且电子控制模块（ECM）已确认燃油压力低于 225 kPa (33 psi) 达 10 秒钟。
系统响应:
ECM 将会记录该事件。
Caterpillar 电子技师（ET）将在任何 Cat ET 状态屏幕上显示 "发动机减额"。 ECM 每秒减少 17.5% 的发动机功率。 最高减额为 39%。 燃油压力升至 235 kPa34 (psi) 以上达 4 秒钟时，ECM 将恢复全功率。
发动机功率减额。
测试步骤 1. 更换燃油滤清器
- 更换发动机的燃油滤清器。 向燃油系统充油。
请参阅发动机的操作和保养手册以了解正确步骤。
- 起动发动机。 使用 Cat ET 检查是否有其他的事件发生。
预期结果:
事件没有重现。
结果:
- 正常 - 事件没有重现。停止
- 异常 - ECM 检测到燃油系统中燃油压力异常。
修复: 关于测试燃油系统的资料，请参阅系统操作/测试和调整, "燃油系统压力 - 测试"。
停止
