有的工程机械在行驶1~2万km后,柴油机就开始冒蓝烟、烧机油,不但使机油消耗量增大,而且使活塞环和气缸磨损加剧,柴油机运转不稳,功率明显下降。出现机油过量消耗的直接原因是机油从活塞和气缸之间窜入了燃烧室。 1.机油过量消耗的原因 (1)气缸、活塞和活塞环对
Some construction machinery in driving 1 to 2 million km, the diesel engine began to take blue smoke, burning oil, not only to increase oil consumption, but also to wear piston rings and cylinder wear and tear, diesel engine instability, power decreased significantly. The direct cause of over-consumption of oil is that the oil has flown into the combustion chamber between the piston and the cylinder. 1. Reasons for excessive oil consumption (1) Cylinder, piston and piston ring pairs
