✦ Synopsis
In this study, influence of fuel and lubricant oil components on the combustion chamber deposit (CCD) formation was investigated using both a two-stroke engine and an autoclave. The results obtained show that the influence of lubricant oil on CCD formation was greater than that of the fuel and most CCD was formed from the detergent dispersant added to the lubricant oil. In particular the metallic detergent formed a larger amount of CCD than the ashless dispersant. The influence of deposit formation under the low-pressure condition on CCD accumulation at the engine appeared to be greater than that of deposit formation under the high-pressure condition.
