Patent ID: 8887704

Claim:
An engine assembly comprising: an engine block at least partially defining a combustion chamber and a crankcase volume; wherein the engine block defines an opening in fluid communication with the crankcase volume; a first air-oil separator mounted to the engine block at the opening and configured to separate oil from blowby gasses flowing through the first air-oil separator from the crankcase volume; a cylinder head mounted to the engine block; an air intake system operatively connected to the cylinder head; a second air-oil separator in fluid communication with the air intake system; wherein the engine block defines a passage that at least partially establishes fluid communication between the first air-oil separator and the second air-oil separator such that oil is first separated from the blowby gasses by the first air-oil separator and is further separated from the blowby gasses by the second air-oil separator; wherein the engine block is configured to support a rotatable crankshaft extending through the crankcase volume; wherein the engine block defines cylinder bores arranged in a first bank and in a second bank in a substantially V-shaped formation about the crankshaft; wherein the cylinder bores of the first bank are axially offset from the cylinder bores of the second bank along an axis of rotation of the crankshaft; and wherein the second air-oil separator is positioned between the banks of cylinder bores in a valley defined by the banks of cylinder bores.
