1.前言发动机的机油,由于金属磨屑、由进气系统侵入到进气空气中的部分尘埃、从活塞环漏入的燃烧生成物中的固化物,以及由于机油本身的氧化而生成的油泥和象清漆那样的非流体或固态微粒等而逐渐被污染。被污染的机油促使润滑部位的腐蚀和磨耗加剧,使燃油和机油的消耗量增大,致使发动机的效率降低。 1. INTRODUCTION Engine oil, metal dust due to intrusion into the intake system by the intake air to some of the dust, combustion products leaked from the piston ring of the cured product, as well as due to oxidation of the oil itself sludge And non-fluid or solid particles such as varnish and the like, which are gradually contaminated. Polluted oil promotes corrosion and wear on the lubricated parts, fuel and oil consumption increases, resulting in reduced engine efficiency.
