CAUSES OF CHANGES IN THE PROPERTIES OF MOTOR OILS IN THE HIGH TEMPERATURE ZONE OF THE ENGINE

This article examines the causes of changes in the properties of motor oils in the high-temperature zone of the engine. The main reason leading to the formation of high-temperature deposits in engines are oxidative processes occurring in the oil volume and on the metal surface. These deposits negatively affect the reliability, efficiency and durability of the engine. We conducted a study of samples of industrial oils M12V2 with a sulfonate additive SK-3. To conduct experiments, the M-12V2 engine oil with the added sulfonate additive SK-3 was analyzed according to physico-chemical parameters for compliance with the requirements. When using such an additive, the service life of the engine oil will increase.
