Soot formation and effect on engine oils

Introduction. During the combustion of diesel fuel in a engine with an increased supply, as result its incomplete combustion, soot particles are formed, which either released into atmosphere or inevitably enter oil. Soot, polluting oil, causes change quality indicators. Soot is very small formed by complex reaction mechanism flame fuel-rich region during hydrocarbons absence air, mainly consisting mixture amorphous carbon and organic matter. Materials methods. This paper presents results literary review aimed at studying ways occurrence operation engines, effect. The mechanical properties also discussed on surfaces friction pairs components. Conclusions. content oil will increase sharply engines exhaust gas recirculation, leads to temperature zones viscosity lubricant, well formation deposits hot parts. These processes occur due discharge crankcase space intensification intake gases from chamber. Oil intervals should be monitored rate entering Scope study / opportunity . type help determine engine, understand consequences using contaminated particles. Originality value. conducted research can basis for development recommendations improving maintenance internal enterprises that have cars their disposal order resource power units reduce operating costs.
