1.前言在发动机中,机油对于润滑摩擦表面防止磨损,保证活塞与缸壁间的气密性以及发动机各部分零件的冷却是不可缺少的。但是,如果发动机机油消耗(以下简称机油消耗)过多,则补充机油所需的保养次数增多,运费也就增加。另外,机油窜入燃烧室内将使活塞积碳增加,火花塞污损,引起活塞环胶结等不良后果。为此,希望尽量降低机油消耗量,以前在这方面已做了大量的研究和改进工作。尤其在近来,为了满足排气净化和降低油耗的社会性要求,装用触媒装置的车辆逐渐增多,从防止机油添加剂使触媒老化的角度来讲,要求机油消耗量降到比以往更低的水平。所
1. Introduction In the engine, lubricating oil for lubricating the surface to prevent wear and tear, to ensure that the piston and cylinder wall between the air tightness and the various parts of the engine cooling is indispensable. However, if the engine oil consumption (hereinafter referred to as oil consumption) is too much, the additional maintenance required to supplement the oil, shipping costs will increase. In addition, the oil fleeing into the combustion chamber will increase the piston carbon deposition, spark plug fouling, causing piston ring cementation and other adverse consequences. To this end, I hope to minimize oil consumption, before in this area has done a lot of research and improvement work. Particularly recently, in order to meet the social requirements of exhaust gas purification and fuel consumption reduction, the number of vehicles equipped with catalyst devices has been gradually increasing, and oil consumption has been required to be reduced to a lower level than ever before in terms of preventing catalyst aging of the oil additives.
