Investigation of effects of boron additives on performance of cam mechanisms

Abstract

The use of additives in the contacting surfaces is essential for the formation of a thin lubricant film, which separates the moving surfaces from each other. Boron compounds, in particular, are very helpful for the sliding surfaces. The aim of the investigation is to clarify how the boron additives influence the lubricating ability of the engine oil using in the sliding contact of the cam-follower. In this study, the considerable results in the tests of engine oil with boron compounds and with base oil are obtained. And also, the influences of the minimize interface friction has been observed under different test conditions.
