In this paper the method of calculating temperature field for medium speed engine piston is presented. The method combines simple analytical formulas for calculating heat load of the piston, MPS-method of Particleworks software for simulating the cooling effect of oil and finite element analysis for calculating the piston temperature field. This calculation model makes it possible to quickly evaluate several different piston cooling designs in early stage of piston design process. Validation results and comparison of simulation times between MPS-method and VOF-method are shown in the paper.
