Abstract: 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.

Abstract: An internal combustion engine includes a cylinder block defining a cylinder and a cylinder head mounted to the block. The cylinder head supplies air and fuel to the cylinder for combustion therein. The engine also includes an exhaust manifold operatively connected to the cylinder head and having first and second outlets configured to exhaust post-combustion gasses from the cylinder. The engine also includes a turbocharging system including a low-flow turbocharger driven by the post-combustion gasses from the first outlet to pressurize the airflow and a high-flow turbocharger driven by the post-combustion gasses from the second outlet. The turbocharging system also includes a flow control device for selectively directing the post-combustion gasses to the low-flow and high-flow turbochargers. The turbocharging system additionally includes a motor-generator to selectively assist the post-combustion gasses in driving either the low-flow or the high-flow turbocharger and generate electric current when driven via the subject turbocharger.
