ANALYSIS OF TRIBOLOGICAL PROCESSES AND INVESTIGATION OF WEAR MECHANISMS IN THE CAMSHAFT OF INTERNAL COMBUSTION ENGINES

Abstract

This study presents a tribological analysis and investigation of wear mechanisms in the camshafts of internal combustion engines. It provides a comprehensive analysis of high contact pressures occurring specifically in the cam-follower pair, instances of elastohydrodynamic lubrication (EHL) breakdown, and adhesive galling resulting from boundary friction, as well as contact-fatigue wear. The impact of modern surface modification techniques and tribochemical additives aimed at reducing component wear is examined on a scientific basis. The results of the research are focused on enhancing engine efficiency and extending operational service life.
