Estimation of oil consumption due to in-cylinder vaproization in internal combustion engines
Two models were developed to estimate the rate of oil consumption due to the vaporization of oil from (1) the cylinder liner and from (2) the piston ringpack in an internal combustion engine. The purpose of the models is to gauge the importance of oil vaporization as a contributor to overall engine …
