Research of the cause of contamination of lubricants used in engines vehicle

Operating oil is constantly changing under the influence of high temperature, oxidizing environment, external contamination, catalysts (wear products of metal surfaces) and other factors. The article discusses the causes of contamination of lubricants used in vehicle engines. Studies of the contamination of lubricating oils during operation of vehicles in hot climates and high dusty air show that lubricants are intensively contaminated with mechanical impurities, water, fuel and organic products, which leads to premature aging of the oil. During operation, in hot weather, especially in conditions of high dustiness of the air and roads, it is necessary to monitor the change in oil viscosity. We analyzed M-10B2 motor oils and calcium alkyl salicinate additives. Studies show that the addition of an additive reduces the process of piston ring wear by 3-4%, as well as an increase in efficiency by 1%, which leads to an increase in engine power by about 4%.
