Abstract
An oil scavenging system for a vehicle engine, which has at least one upward-facing air inlet opening and at least one upward-facing air/oil discharge opening to draw air into the housing through the inlet as the balance shaft rotates and expels air/oil to the engine through the outlet. The inlet opening and the discharge opening are arranged so as to provide for rapid purging of oil from the housing, minimizing oil aeration, heating and motoring losses.
