디젤엔진 피스톤의 열부하에 관한 연구

A study on the Thermal Loading of Diesel Engine Piston

A mechanical linkage system to measure the operating temperature of the piston is developed and installed to the engine. Actual temperature distribution is measured for comparison with the numerical results. Heat transfer at the piston is analyzed using an FEM program. Thermal boundary condition of piston surface is determined by analytical and empirical methods. The temperature distribution and the thermal deformation are obtained by the FEM program.
