推荐的修理

发动机机油中有污垢

排出脏污的发动机机油。 安装新滤清器滤芯。 向发动机中加入清洁的机油。 检查机油滤清器旁通阀的弹簧是否发软或折断。 查找杂质的源头。

进气密封不严

检查空气滤清器有无泄漏。 检查所有密封垫和接头。 如果发现泄漏,应进行修理。

燃油漏入发动机机油中

如果燃油漏入发动机机油中的话,则可能导到燃料消耗量偏高和发动机机油压力偏低。 这种情况也可能会使曲轴箱内的油位升高。 如果发现泄漏,应进行修理。 必要时安装新零件。

使用不正确的发动机机油

检查机油建议资料,了解发动机工况适用的机油技术参数。

保养周期不正确

查阅与发动机特性和严重程度相关的换油周期。 查阅发动机历史记录,以核实遵循建议的换油周期。
