The phenomenon of cavitation in liquid flows occurs in many technical devices, and leads to a decrease in the reliability and efficiency of these devices. One such device is internal combustion engines with liquid cooling systems. Cavitation phenomena in the cooling cavities, together with the corrosive effect of coolants, lead to erosion-corrosion destruction of the cylinder liners. The article proposes criteria for assessing the intensity of erosion-corrosion damage, taking into account the design characteristics of engines, the degree of their forcing, parameters of the operating cycle, operating and water-chemical parameters of cooling. Calculations carried out for various brands of engines made it possible to identify factors affecting the intensity of erosion-corrosion destruction, which include the specific gravity and the degree of forcing. It is shown that the transition to high-temperature cooling and the improvement of the properties of coolants provides a decrease in the intensity of erosion-corrosion damage and increases the service life of engine cylinder liners. The results obtained can be used to adjust the schedules of maintenance and repairs of engines, as well as for the rational choice of cooling modes and properties of coolants.
