The instantaneous temperatures on the piston crown, lands and skirt were measured and analyzed, and the following conclusions can be derived ; ( i ) The linkage system was developed for the measurement of the instantaneous surface temperature of the piston. (ii) The point of crank angle which designates the maximum instantaneous temperature of one cycle varies and moves back and forth by the measuring points and engine speeds, (iii) The engine speeds, the position of the measuring points and the cooling water temperature had an effect on the instantaneous temperature amplitude. (iv) The instantaneous temperature amplitudes appeared on the piston crown, top and 2nd-land of ring, but on the parts of the 3rd-land of the ring and skirt, they didn't appear.<br/>

In this study, the instantaneous temperature probes were developed for the experimental measurement of instantaneous surface temperature on the combustion chamber wall of the DI mono cylinder diesel engine. The instaneous temperatures and heat flux were measured on the cylinder head, piston crown and bowl parts and cylinder liner. The heat transfer coefficient and heat loss which is flowed out through the combution chamber wall could be derived through the calculation process of the measured data.<br/>

In this study, a three-dimensional finite element model was developed for the analysis of the piston of the direct injection mono cylinder diesel engine.<br/> The model which consists of whole piston body to accommodate the eccentric bowl in the piston head. is used to calculate the operating temperature and the corresponding thermal stresses due to the thermal and mechanical loads.<br/> The following conclusion can be derived:<br/> (1) The thermal stress distribution in the piston is not critical. but at its pin hole and bowl inner surface part, the thermal stress is concentrated.<br/> (2) The stress is also generated by the fluttering motion of the piston rings.<br/>
