保护环境,减少空气污染及对人体的影响,改进柴油机排气已成为社会要求.要减少排气中的有害微粒,就要减少其发生源之一的未燃烧的发动机油,亦即降低润滑油消耗的要求.关于降低润滑油消耗,以前虽有很多论文报道,但本文就第一道环对润滑油消耗的影响及其机理进行论述.2润滑油消耗的机理在本文之前关于润滑油消耗的机理概况.已有论述.图1为润滑油消耗的状况,其中影响最大的是从活塞,活塞环周围的窜油,其窜油途径如图2所示. To protect the environment, reduce air pollution and human impact, to improve diesel exhaust has become a social requirement.To reduce the harmful particles in the exhaust, it is necessary to reduce one of its sources of unburned engine oil, that is to reduce the lubricating oil On the reduction of oil consumption, although a lot of papers have been reported before, but this article on the first ring on the impact of lubricant consumption and its mechanism.2 The mechanism of lubricant consumption in this article on the consumption of oil Mechanism has been discussed.Figure 1 shows the status of lubricant consumption, of which the most influential is from the piston, piston ring around the oil, the channeling path oil as shown in Figure 2.
