采用本步骤进行进气系统高压差的诊断与排除。 此外,如果以下任一发动机事件为激活状态,应使用本步骤。 有关发动机事件的信息,请参阅故障诊断与排除, "故障诊断代码"。 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。 有关发动机监测系统的信息,请参阅系统操作, "发动机监测参数"。

表 1
发动机事件    
J1939 代码和说明     产生此代码的状况     系统响应    
107-15 发动机空气滤清器 1 压差:高 - 最低严重程度 (1)     空气滤清器压差高于触发点压力已达到延迟时间。     记录该代码。    
107-16 发动机空气滤清器 1 压差:高 - 中等严重程度 (2)     记录该代码。
发动机功率减额。

可能原因

  • 空气滤清器滤芯

  • 进气管路

  • 大气压力传感器、涡轮增压器压缩机进口压力传感器和/或传感器电路

  • 护罩

建议的措施

空气滤清器滤芯

检查进气系统有无空气滤清器阻塞或损坏的情况。 如果发动机配备进气预滤器,则请确认进气预滤器工作正常。

进气管路

检查进气管路有无损坏或阻塞。 修理或更换管路。

护罩

检查并确认发动机安装在通风良好的护罩中。 修理护罩的通风装置。

大气压力传感器、进气压差传感器和/或传感器电路

在发动机停机时,使用 Cat ET 比较以下参数的状态:

  • "大气压力"

  • "进气压差传感器"

检查并确认传感器接线正确。

Cat ET 将会把 "Atmospheric Pressure(大气压力)"的状态报告为周围区域的大气压力。 发动机熄火时,进气压差传感器的读数与大气压力传感器大致相同。 如果读数不一致,则对可疑传感器的传感器电路进行故障诊断与排除。 请参考故障诊断与排除, "传感器信号(模拟、有源)- 测试"。
