Excessive Engine Oil Consumption - Inspect
检查曲轴两端的油封是否漏油。 查看发动机油底壳密封垫和所有润滑系统接头有无渗漏。 查看曲轴箱通气装置是否有任何漏油。 这可能是由于燃烧气体从活塞周围的漏出导致的。 肮脏的曲轴箱通气装置会造成曲轴箱压力高。 肮脏的曲轴箱通气装置也会导致密封垫和密封渗漏。
发动机机油漏进气缸的燃烧区域会造成排气冒蓝烟。 机油可能通过四种途径漏入气缸的燃烧区域：
- 通过磨损的气门导管和气门杆之间漏入
- 磨损或损坏的部件(活塞、活塞环或油环槽内肮脏的发动机机油回油孔)
- 压缩环和/或中间环安装不正确
- 曲轴箱机油加注过满
- 安装了错误的油位表或导管
- 发动机长时间轻负荷运转
如果使用的发动机机油粘度不正确，也会造成发动机机油消耗量过多。 发动机温度升高会导致机油粘度变稀。
