| Abstract: | The transient thermo-elastohydrodynamic (TEHL) lubrication simulation and isothermal elastohydrodynamic (EHL) simulation were
performed on the exhausting camtappet friction pair of an internal combustion engine. Although by employing the two models
the center pressure, the thickness of the lubricant film and friction coefficient obtained were similar in the changing trend
during a rotating cycle, the parameters make a great difference, especially for the thickness of the lubricant film; the TEHL
was four times thicker than the EHL. These results show that the temperature should not be neglected in the study of the lubrication
of cam-tappet pairs.
