초록
High power and high efficiency has been required in internal combustion engine. Accordingly, the thermal load deformation, thermal stress and temperature on piston become higher at newly developed engines. To investigate the cooling effect of piston, a few types of piston design is presented and finite element method is carried out to analysis the heat transfer and the thermal stress. The piston which has upwards shifted cooling gallery is also analyzed to investigate the thermal load effect of oil jet cooling.
