MATERIALS FOR INCREASED PERFORMANCE CHARACTERISTICS OF MOTOR OILS, METHOD OF STABILIZING PROPERTIES OF MOTOR OILS AND/OR OPTIMIZING THIBOCHEMICAL CONDITIONS IN OIL SYSTEM OF INTERNAL COMBUSTION ENGINE

摘要

FIELD: lubricants. SUBSTANCE: objective is achieved by using material containing (i) 0.1 to 95.0% iodine-containing compound, basically NaI or NalO₃ and/or l₂ and 0.1 to 50% Na₂SnO₃; or (ii) 1 to 40% Na, 20-89% Sn, and additionally 10 to 60% Al. Composite material contains 90% Nal-NalO₃-l₂ and 10 to 90% Na-Sn-Al. Motor oil is passed through alkaline agent based on alkali metal, tin, and halogen-containing component, where, as alkaline reagent and/or halogen-containing component, above- indicated materials or their combinations are used by way of introducing them directly into engine case or placing them into engine oil system circuit. EFFECT: restored working characteristics of worn engine and reduced injurious emissions out of working engine. 17 cl, 5 tbl
