Research of the cause of contamination of lubricants used in vehicles

Studies of the contamination of lubricating oils during operation in hot climates and high air dust content show that lubricants are intensively contaminated with mechanical impurities, water, fuel and organic products, which leads to premature aging of the oil. During operation, engine components and parts are contaminated with various deposits. The process of formation of deposits is associated with thermo-oxidative transformations of products of incomplete combustion of fuel and oil components. These transformations take place both in the volume of the oil and in its thin layer on a heated metal surface. The resistance of the oil against oxidation by atmospheric oxygen is one of the most important factors that determine the behavior of the oil in the friction units during operation. We analyzed M-10V2 motor oils and calcium alkyl salicinate additives. After the introduction of such a concentration of the additive into the oil, we observed its dissolution. Studies show that the addition of a 9% 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%.
