Chemical and physical assessment of engine oils degradation and additive depletion by soot

Soot contamination in engine oil causes a significant increase wear of components. Presence soot the is one most common reasons leading to an change intervals. There are several mechanisms that affect performance such as degradation, additive decomposition and adsorption on particles. It recommended removal from can reduce components extend service life oil. However, removing particles diminish efficiency additives oils some adsorbs these still no census this area. Thus, experimental study aims investigate how different levels Carbon Black Particles (CBP), commonly used surrogate for soot, aged influences performance. The reveals three main influence tribological expressed depletion, degradation products. Removal CBP expected reclaim results demonstrate after not good fresh These confirms reclaiming be achieved by just CBP. Other adversely during
