摘要
汽车工业的发展带来了空气污染的负面效应,因此相继建立了排放法规,排放法规对车用发动机提出了严格的要求,也对车用机油的性能提出了更加苛刻的要求,从而促进了车用机油的升级换代。
On accounts of negative effects of air pollution accompanying with the development of automobile industry, emission standards were carried out gradually, which preferred more stringent requests on vehicular engines, as well as the performances of vehicular lube oil. This situation promotes the upgrade of vehicular lube oil.
