不要在机油压力低的情况下运转发动机。 这样会造成发动机损坏。 如果测得的机油压力低，请停止运转发动机，直到问题得以解决。 |
- 发动机机油油位低
- 发动机机油滤清器脏污
- 发动机机油泵堵塞
- 发动机机油冷却器堵塞
- 发动机机油被燃油稀释
- 凸轮轴和/或凸轮轴轴承
- 曲轴轴承
检查发动机机油油位。 如果发动机机油油位低，则添加发动机机油。
检查发动机机油滤清器。 如果发动机机油滤清器脏污，请安装一个新的发动机机油滤清器。 检查滤清器旁通阀的工作情况。 清洁旁通阀及壳体。 如有必要，请安装新零件。
检查发动机机油泵的进口滤网是否堵塞。 检查发动机机油泵有无过度磨损。
检查发动机机油冷却器。 清洁发动机机油冷却器芯和/或安装新的发动机机油冷却器芯。
检查润滑油中是否存在燃油。 请参考故障诊断和排除 , "发动机机油被燃油稀释 "部分的诊断程序。
检查凸轮轴和/或凸轮轴轴承。 检查各零部件有无过度磨损。 如果有过度磨损，则说明油路堵塞。 检查曲轴和/或曲轴轴承。 检查各零部件有无过度磨损。
