Engine Has Early Wear
注: 这不是电子系统的故障。
- 多次起动或冷态操作
- 保养周期不正确
- 发动机机油内的污垢
- 不正确的机油
- 污染的机油
- 进气系统泄漏
- 燃油内的污垢
- 机油压力过低
频繁起动和停止发动机会造成发动机过早磨损。 另外,经常在寒冷条件下短时间运转发动机也会造成发动机过早磨损。
发动机如果没有得到正确保养,就会过早磨损。
确保以正确的保养周期对发动机进行保养。 请参阅操作和保养手册 , "保养周期表" 。
- 排空曲轴箱中的机油,然后向曲轴箱重新加注清洁的发动机机油。 安装新发动机机油滤清器。 请参阅操作和保养手册 以了解更多信息。
- 检查发动机加注了规格正确的机油。 请参阅操作和维护手册 , "加注容量和建议 "。
- 如有必要,将发动机油系统排空,并重新加注发动机机油。 请参阅操作和保养手册 , "发动机机油和滤清器 - 更换"。
检查机油样本是否被燃油污染。 如果发现污染,应调查原因。
进气系统漏气可能导致未经过滤的空气进入发动机。 检查进气系统是否存在条痕,条痕表示进入了未经滤的空气。 检查所有垫片和连接。 修理所有泄漏的地方。 有关更多信息,请参阅 系统运行、测试与调整 , "进气系统" 。
- 卸下燃油滤清器。 检查燃油滤清器是否有杂质。 安装新燃油滤清器。 请参阅操作和维护手册 , "燃油系统滤清器 - 更换"和 操作和维护手册 , "燃油系统粗滤器(油水分离器)滤芯- 更换"。 确定产生杂质的原因。
- 检查柴油是否受污染。 请参阅系统操作、测试与调整 , "燃油质量 - 测试 "。
有关测试程序,请参阅 故障排除, "发动机机油压力低"。 修理所有发现的故障。
