Abstract
An engine assembly includes a vapor canister in selective fluid communication with a crankcase to store alcohol vapor when the temperature inside the crankcase causes alcohol accumulated in the crankcase to boil. The vapor canister is in selective fluid communication with an air induction system to recirculate the alcohol vapor through the engine in a metered fashion.
