Oil loss mechanisms in internal combustion engines have been subject to many
researches. By the help of technological developments effects of several problems
due to oil losses were examined and tried to be reduced. Environmental pollution and
performance loss are important issues that oil consumption in internal combustion
engines contribute. In this study the effects of individual parameters on the oil
accumulation in 2nd land crevice of internal combustion engines, volume between
top compression rings, were investigated.
The study aimed to investigate the effects of oil film thickness and oil film
temperature on the oil accumulation in the 2nd land which contributes to one of the
mechanisms of oil consumption in internal combustion engines. Controlled
experiments were performed on a modeled piston cylinder assembly.
It was seen that oil accumulated in the 2nd land crevice by blow-by gases was
affected by the film thickness of lubricating oil and the temperature of the lubricating
oil. The amount of oil accumulated increased with increasing oil film thickness. The results also showed that below oil film thickness of 45 & / #956 / m / amount of oil
accumulated increased with the increase of oil temperature.
