Influence of operational factors on the properties of working fluids of piston engines

The paper is devoted to the study of regularities changes in quality working fluids circulating through systems internal combustion piston engines. During research, parameters that characterize its operational properties, as well external effects can lead properties fluid, were determined. It shown deterioration engine oil and coolant engines during operation caused by destruction additives are part fluid provide their required properties. A laboratory installation has been developed created allows simulating thermal mechanical on similar those acting circulation systems. graphical dependencies obtained a result experiment presented. Mathematical processing experimental data allowed obtaining regression correctly describe processes time most important characteristics under action cyclic effects. described method be used influence factors various
