Engine Has Early Wear
- 发动机机油不正确
- 发动机机油污染
- 空气污染
- 燃油污染
- 机油压力过低
使用发动机操作和保养手册中建议的发动机机油,并按手册中建议的周期更换发动机机油。
排空曲轴箱,使用清洁的发动机机油重新加注曲轴箱。 安装新发动机机油滤清器。 请参阅发动机操作和保养手册。
如果机油滤清器旁通阀开启的话,将会导致机油未经过滤。 检查机油滤清器旁通阀的弹簧是否发软或折断。 如果弹簧折断了的话,应更换弹簧。 请参阅发动机的解体与组装手册。 确保机油旁通阀操作正确。
检查进气系统有无泄漏。 检查所有垫片和连接。 修理所有泄漏的地方。
检查空气滤清器。 必要时更换空气滤清器。
检查燃油滤清器。 必要时更换燃油滤清器。
燃油中的硫化氢和硫等杂质会导致曲轴箱中形成酸性物质。 获取燃油分析。
当发动机的某些部件短期内显示轴承磨损时,其原因可能是机油通道阻塞。
发动机的机油压力表可能会指示有足够的机油压力,但是部件却因缺乏润滑而磨损。 在这种情况下,应查看向该部件供油的通道。 请参阅系统操作 / 测试和调整手册。
