水分对发动机油性能的影响

The Influence of Water on the Performance of Engine Oil

选取目前市场在售发动机油产品,加入一定比例蒸馏水,考察水分对发动机油外观、黏温性能、低温性能、摩擦磨损性能、抗氧化性能和抗腐蚀性能的影响。结果表明,不同配方体系乳化保持性能有所差异;水分的存在会对油品的低温性能、抗磨损性能、抗氧化性能、抗腐蚀性能等造成负面影响。

Select engine oil products available in the market,add a certain proportion of water,and investigate the effect on the appearance,viscosity temperature performance,low temperature performance,friction and wear performance,antioxidant performance,and corrosion resistance of engine oil.The results show that there are differences in emulsion retention performance among different formulation systems.Water can have a negative impact on the low-temperature performance,wear resistance,antioxidant performance,corrosion resistance,etc.of engine oil.
