Numerical and Experimental Investigations of Tribosystems of Piston Engines Taking into Account Boundary Lubrication Regime, Macro and Microgeometry of Contact Interface
Reducing friction induced energy dissipation in widespread tribosystems is a primary goal in economy. Especially in the automotive industry, companies are trying to reduce the huge amount of tribological caused energy losses to diminish fuel consumption. In an internal combustion engine (ICE) of nowadays passenger cars, for example 38-68% of the total frictional losses result from the piston assembly and 20-44% is consumed in bearings [1]. A detailed investigation of surface interaction processes will help in finding enhanced technical solutions with optimized design according to energy efficiency and service life.
