Abstract

<div class="section abstract"><div class="htmlview paragraph">Regarding the solution for various issues on engine tribology, in order to understand the involvement of temperature in the friction and scuffing under the mixed and/or boundary lubrication regime, the two cases of piston ring &amp; cylinder liner and cam &amp; tappet were analytically studied. The friction between sliding interfaces is composed of four shear stresses from the viscous oil-films, the adsorbed oil molecules, the tribofilms due to oil additives, and the true metal contacts on surface asperities. Since all the shear stress have exponential temperature dependences, the relationship between the frictional shear stress and temperature is assumed to be expressed by the Arrhenius equation. Through analyzing friction data measured in laboratory tests conducted under the same temperature and sliding conditions as during the break-in of engines, various levels of temperature involvement were clarified.</div></div>
