Abstract

Abstract The foaming and aeration properties of crankcase oils were investigated through the observation of foam behavior in the crankcase. Entrained air bubbles in the crankcase oil, that is oil aeration, increased as engine speed and oil temperature increased. This also depended on oil formulation. However, surface foam disappeared in high-speed conditions. It was found that the aeration performance of oils had an effect mainly on the connecting-rod bearing wear under high speed-high temperature engine operating conditions.
