oil leakage, as the name suggests, refers to the oil leakage. Is usually due to engine cylinder gasket, oil pan gasket, the sealing ring is damaged, or before and after the crankshaft oil seal, camshaft oil seal is damaged, or the fastening screw loosening caused, parking inspection found oil leakage, serious oil decrease obviously, engine protection plate convergence has large oil.

burning oil is the oil into the combustion chamber, and fuel in combustion, exhaust pipe to take the blue smoke. There are two main sources of oil entering the combustion chamber. First, from the cylinder head. Valve seal aging, sealing performance decreased, resulting in oil penetration into the combustion chamber. The engine is stationary for a long time, the oil from the valve seal into the cylinder, start the engine, the exhaust pipe has the thick smoke, i.e.cold car burning oil. In addition, the valve liner is partially worn, resulting in an increase in clearance between the valve and the valve, and the oil enters the combustion chamber. Second, comes from the cylinder block. Excessive wear of piston, piston ring groove piston ring elasticity damage or excessive wear or even failure, will cause Mifengbuyan, splashing oil into the combustion chamber, in combustion, when accelerating performance significantly. In addition, excessive cylinder wear or uneven wear, piston ring on the excessive oil can not be scraped down, resulting in burning oil.

  漏机油,顾名思义,Nike Air VaporMax 2.0 Hot Punch,指的是机油泄漏。一般是由于发动机气缸垫、油底壳衬垫、密封圈损坏,或者曲轴前后油封、凸轮轴油封损坏,亦或是各紧固螺丝松动等造成的,停车检查发现有机油渗出,严重者机油减少量较为明显,发动机护板会聚有大量机油。

  烧机油是机油进入燃烧室,与燃油一起参与燃烧,排气管冒蓝烟。进入燃烧室的机油主要有两个来源。其一,来自缸盖。气门油封老化,密封性能下降致使机油渗入燃烧室。发动机长时间静止,机油从气门油封流入气缸,启动发动机,排气管有较浓的蓝烟,即冷车烧机油。此外,气门导管偏磨,致使与气门的间隙增大,机油进入燃烧室。其二,来自缸体,Zapatos Nike Air Safari OG。活塞磨损过大,活塞环槽损坏,活塞环弹性减弱或磨损过度甚至失效,均会导致密封不严,飞溅上来的机油进入燃烧室,Nike Air M,参与燃烧,在加速时表现明显,Nike Pre-L。另外,缸筒磨损过大或者磨损不均,活塞环带上去的过量机油不能被刮下来,从而引起烧机油。
