EFFECTS OF MOTOR OILS ON VEHICLE OPERATION

Abstract

The article discusses the issues of development of limit values of quality indicators of motor oils in climatic conditions of the Republic of Uzbekistan. The quality of engine oil greatly affects basic criteria, resource and technical condition of the engine, as well as - consumption and timing of the engine oil change. Timing of oil replacement depends on the value of its limit values in operating conditions.
Engine oils are an essential element of the engine design, and the quality of lubricants affects fuel economy and engine durability. Small stocks and high cost of oil products require their ef�icient use. The research relevance is explained by the need to study changes in qualitative indicators of motor oils, their negative effect on the ef�iciency of operation of vehicles, as well as mitigation of these effects caused by climatic conditions. Factors including physical and chemical properties and performance indicators of motor oils, were taken as the research subject. The main objectives of the study include review of the relevant literature concerning the limit values of quality indicators of motor oils in operating conditions and the range of motor oils. Experimental studies in laboratory conditions have been made, criteria for assessing the quality indicators of motor oils under operating conditions - selected. And limit values of quality indicators of motor oils have also been developed.
