Abstract

The purpose of this work is to study the causes of changes in the viscosity parameters of lubricants and their effect on engine operation. The less the viscosity changes with temperature changes, the better the starting qualities of the engine. The coefficient of friction depends on the viscosity, and consequently, the reliability and efficiency of the machine, aggregates and friction units. The oil viscosity may increase and decrease during engine operation. To improve the viscosity-temperature characteristics, viscous additives are used. They increase the fluidity of oils at low temperatures and stabilize the viscosity at high temperatures.
