Abstract

See full text

An engine assembly includes a two-cylinder engine, an intake assembly, and an air-oil separator. The two-cylinder engine defines a first cylinder bore, a first combustion chamber, a second cylinder bore, a second combustion chamber, and a crankcase volume. The engine further includes a first piston disposed within the first cylinder bore, and a second piston disposed within the second cylinder bore. The intake assembly includes an intake manifold in fluid communication with each of the first and second combustion chambers, and the air-oil separator defines a separator volume and in fluid communication with each of the crankcase volume and the intake manifold. A reciprocal, synchronous motion of the first and second pistons is operative to exhale gas from the crankcase volume through the separator volume and into the intake manifold.
