为何要选用适合发动机的润滑油
Why choose the lubricating oil suitable for the engine
润滑油使用过程中都会因油泥胶质的生成导致粘度增加。而润滑油使用中有粘度下降的现象,则是因为选用了低粘度基础油,同时选择了较多的高分子聚合物提升粘度,在润滑油使用过程中,在长时间高温高压力作用下,导致高分子烃类聚合物分子链断裂,从而导致粘度下降,所以,粘度的变化程度跟润滑油有的品质有关系。
The viscosity of lubricating oil will increase due to the formation of sludge gum during the use. The viscosity drop of lubricating oil in use is due to the selection of low viscosity base oil and the selection of more high molecular polymers to increase the viscosity. During the use of lubricating oil, under the action of high temperature and high pressure for a long time, the molecular chain of high molecular hydrocarbon polymers breaks, which leads to the viscosity drop. Therefore, the degree of viscosity change is related to the quality of lubricating oil.
至于什么发动机使用什么粘度机油,则跟气候、发动机的工作状态有关。比如南方地区比北方地区气温高,冬季和春秋季相同工况的发动机使用润滑油的粘度就要略高一些。另外,燃气发动机工作温度比燃油发动机温度高几十度,为了维护高温的油膜稳定性,要求油品粘度相对略高些,同时维护老型发动机活塞与缸体间的高温密封性,也要求燃气发动机润滑油具有更好的粘度和粘度稳定性。
As for what engine uses what viscosity oil, it is related to the climate and the working state of the engine. For example, the temperature in the south is higher than that in the north, and the viscosity of lubricating oil used by engines under the same working conditions in winter and spring and autumn is slightly higher. In addition, the working temperature of the gas engine is dozens of degrees higher than that of the fuel engine. In order to maintain the high temperature oil film stability, the oil viscosity is required to be slightly higher. At the same time, to maintain the high temperature sealing between the piston and the cylinder block of the old engine, the gas engine lubricating oil is also required to have better viscosity and viscosity stability.
另外,评价一款润滑油品质的好坏,主要看它的粘度稳定性能、粘度大则油膜较厚,适合于活塞缸体间隙较大的老发动机,粘度小则油膜较薄,适合活塞缸体间隙较小的新发动机,此时选用高粘度润滑油肯定费燃料。但无论粘度大或小,油品高温状态下的抗氧化、抗变质性能一定要好。
In addition, the quality of a lubricating oil is evaluated mainly by its viscosity stability. If the viscosity is large, the oil film is thick. It is suitable for old engines with large piston cylinder clearances, and if the viscosity is small, the oil film is thin. It is suitable for new engines with small piston cylinder clearances. At this time, selecting high viscosity lubricating oil will definitely cost fuel. However, no matter the viscosity is large or small, the oxidation resistance and anti deterioration performance of the oil at high temperature must be better.
