Abstract
Various systems and methods are described for reducing engine oil dilution in a boosted engine. One method comprises, when engine oil dilution is higher than a first threshold and engine oil temperature is below a temperature threshold, adjusting a position of an air induction system (AIS) throttle, generating a vacuum, and providing the vacuum to a crankcase of the boosted engine to enhance fuel evaporation from engine oil. The providing of vacuum may be discontinued when engine oil dilution is lower than the first threshold and/or when engine oil temperature rises above the temperature threshold.
