一、我国车用发动机润滑油的分类作为各类汽车动力装置的内燃机品种繁多,对润滑油的要求差异甚大,因此,润滑油相应地也有不同类别。我国车用汽油机润滑油按其100℃时的运动粘度分为6号低凝、6号、10号和15号四个牌号,此外还有8号低凝和14号合成稠化机油两种。它们的主要性能规格见表1。我国车用柴油机润滑油按其100℃时的运动粘度分为8号、11号和14号三个牌号。其性能规格见表2。另有低增压柴油机润滑油11号和14号,其性能规格见表3。我国发动机润滑油按用途分类,及其与API(美国石油学会)分类的对应关系见表4。
First, the classification of automotive engine lubricants As a variety of automotive power plant internal combustion engine variety, very different requirements for lubricants, therefore, there are different types of lubricants accordingly. China’s automobile gasoline engine lubricating oil viscosity according to its 100 ° C is divided into 6 low condensing, 6, 10 and 15 four brands, in addition to low condensing No. 8 and No. 14 synthetic two thickening oil. Their main performance specifications in Table 1. China’s automotive diesel lubricants according to their kinematic viscosity at 100 ℃ is divided into 8, 11 and 14 three brands. Its performance specifications in Table 2. Another low turbocharged diesel engine oil No. 11 and No. 14, the performance specifications in Table 3. China’s engine oil by use classification, and its correspondence with the API (American Petroleum Institute) classification shown in Table 4.
