Abstract

An internal combustion engine has a crankcase, a crankshaft, a cylinder block, and cylinder head assembly. The cylinder block has at least one cylinder. At least one piston is disposed in the at least one cylinder. The at least one piston is operatively connected to the crankshaft. An oil tank enclosure is connected to at least one of the crankcase outer wall and the cylinder block outer wall. The oil tank enclosure and the at least one of the crankcase outer wall and the cylinder block outer wall together form an oil tank. The arrangement of the oil inlet, oil outlet, and blow-by gas outlet in an oil tank; an oil tank having an angled portion for separating blow-by gases from oil; and an arrangement of a blow-by gas passage connected to an oil tank are also described.
