Abstract
An engine assembly includes an engine structure, an air intake assembly and a positive crankcase ventilation system. The engine structure defines an intake port and a crankcase. Furthermore, the air intake assembly is in communication with the intake port. The positive crankcase ventilation system includes a fresh air line, a housing and a foul air line. The fresh air line is in communication with the air intake assembly and the crankcase. The housing defines an air inlet and an air outlet with the air inlet being in communication with the crankcase and partially defined by a wall extending into an inner volume of the housing. An oil separation mechanism may be located in the housing between the air inlet and the air outlet. The foul air line is in communication with the air intake assembly and the air outlet.
