Engine oil characteristics changes in uprated diesels

Abstract

The problems of estimating the periodicity of engine oil replacement in high-powered internal combustion engines during operation, which operate with increased thermal stress and oil consumption on the "fumes" are identified. On the basis of the laws of chemical kinetics theoretically investigated and experimentally confirmed the mechanism of aging and changes in the concentration of motor oil additives. The step-by-step adjustment of the periodicity of engine oil change depending on the operating time of high-powered KAMAZ engines is justified.The problems of estimating the periodicity of engine oil replacement in high-powered internal combustion engines during operation, which operate with increased thermal stress and oil consumption on the "fumes" are identified.
