Excessive Engine Oil Consumption - Inspect
检查曲轴两端的油封是否漏油。 查看油底壳密封垫和润滑系统所有接头是否漏油。 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。
机油漏进气缸燃烧室会导致发动机冒蓝烟。 机油可能通过四种途径漏入气缸燃烧室：
- 磨损的气门导管和气门杆之间的机油渗漏
- 磨损或损坏的部件（活塞、活塞环或肮脏的回油孔）
- 压缩环和/或中间环安装不正确
- 机油通过涡轮增压器轴的叶轮端的密封环漏入
使用粘度不对的机油也可能造成机油消耗量过大。 燃油漏进曲轴箱或发动机温度升高都会使机油粘度变稀。
