Abstract
Recently, the bearing performances have been analyzed by elastohydrodynamic lubrication theory (EHL). However, the oil film temperature is constant within a bearing clearance on this theory. As modern automotive engines are running at high rotational speed, the change of the oil film temperature is remarkable within a bearing clearance. The bearing performances are influenced by the distribution of the oil film temperature. Therefore it is also necessary for the analysis of the bearing performances to consider the effect of the oil film temperature distribution by thermo elastohydrodynamic lubrication theory (TEHL).
In this study, the effects of the bearing performances are investigated on connecting rod bearing in general gasoline engine by TEHL. Furthermore, oil film thickness, oil film pressure and oil film temperature of TEHL results are compared with those of EHL.
