INVESTIGATION OF THE INFLUENCE OF OPERATIONAL PROPERTIES ENGINE OILS FOR WEAR OF ENGINE PARTS
Keywords:
oil quality, contamination, viscosity, alkaline number, varnish deposits, piston rings, experimental data, cleaning additivesAbstract
This article examines the changes in oil quality during engine operation. 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. The greatest danger of varnish deposition is for piston rings. By filling the gaps formed by the piston rings and the grooves drilled in the pistons, it reduces the mobility of the rings. Therefore, we suggest introducing detergent additives into the engine oil.
As detergent additives, we used the detergent additive alkylphenol with phosphorus pentasulfide and calcium salts (calcium alkylarylsulfonate). The effect of such additives gives the ability to loosen, wash off deposits from the surface of parts and transfer insoluble substances into suspension. Having determined the dissolution of the additive in the engine oil, we determined the physico-chemical parameters of the engine oil for different concentrations of additives.
