Abstract
An engine assembly includes an engine and an intake assembly. The engine defines a combustion chamber and a crankcase, and the intake assembly includes an intake manifold in fluid communication with the combustion chamber. An air-oil separator is provided with the engine and defines a separator volume, an inlet and an outlet, where each of the inlet and outlet are in fluid communication with the separator volume. The inlet of the air-oil separator is provided in fluid communication with the crankcase, and the outlet of the air-oil separator is provided in fluid communication with the intake manifold. The air-oil separator further includes an interior surface that abuts and surrounds the separator volume, and the interior surface has a surface roughness (RA) of greater than about 75 microns.
