考察了不同组成的内燃机油复合剂对油品运动粘度的影响。结果表明,由不同类型无灰分散剂组成的内燃机油复合剂对油品运动粘度存在不同影响,其中含高分子无灰分散剂的复合剂的增粘作用较大,且复合剂对油品运动粘度影响的大小与油中是否存在粘度指数改进剂有关。
The effects of different compositions of internal combustion engine oil on kinematic viscosity of oil products were investigated. The results show that different types of ashless dispersants composed of diesel engine oil viscosity have different effects on the kinematic viscosity of oil containing polymer ashless dispersant thickening effect of the larger, and the complex viscosity of the oil kinematic viscosity The size of the oil viscosity index improver presence or not.
