| Popis: | This paper describes the mechanism of the operating factors’ influence on the operating modes of the internal combustion engine (ICE) and the intensity of changes in the technical condition of its main interacting components. It considers changes in the physical and chemical properties of engine oil and its effect on the content of harmful substances in the exhaust gases of the internal combustion engine. The characteristic uprating of modern automobile diesel engines significantly worsens the operating conditions of both friction pairs and oil. Ensuring the reliable operation of such uprated engines is possible by improving the lubrication system and the quality of oils used. The performance properties of engine oils have a great influence on the efficiency of internal combustion engines and largely determine their reliability and durability as well as environmental impact. One of the important factors is the wear resistance of friction pairs, which directly depends on the metal-physical characteristics of the friction surfaces as well as the physical and chemical properties of engine oils, methods of their supply to friction units, and the design of the lubrication system. Based on studies conducted at the Yuri Gagarin State Technical University of Saratov we determined patterns of engine oil aging and its consumption, depending on operating factors, especially in uprated engines operating at maximum speeds and loads. |
