The paper presents an analysis of piston thermal loads in an opposed piston engine. The purpose of the work was to check the achieved thermal values of different piston models. Two types of pistons were analysed. The first piston was made entirely of aluminium. The second one was a split piston, made of steel and aluminium. Simulation studies were performed using Abaqus software. Boundary conditions were taken from previously made simulations conducted in AVL Fire software. The wall temperature of the piston was mapped from CFD combustion model. The results of the analyses were illustrated by the distribution of temperature fields on a piston surface. The distribution of temperature fields on the piston surface shows that maximum temperatures are located on sharp edges of a piston bowl, values of maximum temperatures are 402 and 512 °C for aluminium and composed piston respectively.
