IMPROVING THE WORKING CONDITIONS OF FRICTION BY USING OPERATION ADDITIVES TO LUBRICATING OIL
Journal Title: Tribologia - Year 2014, Vol 253, Issue 1
Abstract
This paper presents the results of laboratory testing and verification on the actual technical facilities for lubricating oil CE/SF SAE 15W/40 and modified operational preparations with chemicals based on solid lubricants and causing a selective transfer effect. Laboratory tests included the appointment of indicators characterizing the lubricating properties, which are weld load, no scuffing load, wear under load, and scuffing load consumption, by measuring the average diameter of the flaws in the balls still involved in the determination of welding load. After laboratory tests were carried out, verification tests were made on the engines of buses after the operation about 20 thousand kilometres. After the trial operation of bus engines, designated lubricating and physicochemical properties and iron content in the lubricants were determined. Studies showed that preparations made to the oil supplies (commercial CE/SF SAE 15W/40) influenced the growth of antiseizure properties and anti-oil before and after the operation of the engines of buses for about 20 thousand kilometres. Preparation supplies contributed to a smaller decrease in oil viscosity measured at 40°C and 100°C, compared to the trade-grade oil, reduced the decline in the alkaline level, and resulted in a smaller increase in the iron content in oils.
