The AVL BOOST software was adopted to calculate the working process of piston, and its heat exchange boundary condition and its highest combustion pressure were obtained. Based on the results, the temperature field of piston with or without cooling and its coupling stress and deformation were analyzed using FEM software ANSYS. Moreover, the connecting bolts of piston were examined for its stress intensity.
