In this study, the instantaneous heat flux measurement probe and the linkage system for the measurement of the instantaneous temperature and heat flux of the DI mono cylinder diesel engine were developed, and these were proved to have a good reliability and sensibility. A 3-D FEM model which consist of full piston to accommodate the eccentric bowl in the piston head, was applied for the analysis of the thermal stress and the temperature distribution. The mean heat flux on the piston head was used as boundary condition for the analysis of piston. The analysis showed that thermal stress concentrate on the bowl and inner surface of pin hall.
