摘要

This study presents a finite element heat transfer model for the prediction of piston temperature distributions in a real time operation engine. The thermal boundary conditions are specified adequately in the model for various operations. The time-mean, area-averaged gas temperature and heat transfer coefficient could be obtained from the engine simulation. The ambient temperatures along the piston ring belt and skirt were estimated with a formula and the corresponding heat transfer coefficients were arrived at through equivalent thermal circuit analysis. The model is also calibrated and the predicted and measured temperatures compared for the operating engine. The predictions are reasonable, providing confidence in the use of the simulation model.
