一台170F型柴油机烧漏机油严重。经检查原因是曲轴箱通气口滤网严重堵塞。随着机器的长期使用,曲轴箱通气口盖内的滤网逐渐被油污堵塞,使燃烧室窜入曲轴箱内的气体不能及时排出、曲轴箱内压力升高,造成部分机油通过缸套与活塞之间的间隙窜入燃烧室燃烧;同时部分机油则通过曲轴箱各接合面被挤出箱外,使机油消耗过多。因此,使用中必须定期(一 A 170F diesel engine oil leakage serious. After checking the reason is a serious blockage of the crankcase vent filter. With the long-term use of the machine, the filter inside the crankcase vent cover is gradually clogged with oil, so that the gas exiting into the crankcase of the combustion chamber can not be discharged in time. The pressure in the crankcase is increased, causing part of the oil to pass through the cylinder liner and the piston The gap fleeing into the combustion chamber combustion; at the same time part of the oil through the crankcase joints are squeezed out of the box, so that oil consumption too much. Therefore, the use must be regular (one
