Originální abstrakt

The paper presents computational methods suitable for the solution of powertrain mechanical losses using the virtual engine. There are presented mainly computational models for the solution of friction losses of a piston assembly, slide bearings or valvetrain contact couples. Mixed lubrication is solved in detail for the specified powertrain parts. Hydrodynamic parts of solutions come from the Reynolds equation solution. A boundary lubrication model includes influences of surface roughness on contact pressure. Mechanical loss results for main powertrain parts are presented for the diesel in-line four-cylinder engine. The chosen computational results are validated by measurements.
