<p>An oil scavenging system for a vehicle engine, which has a balance shaft housing (10) including at least one upward-facing air inlet opening (36, 38, 39, 41) and at least one upward-facing air/oil discharge opening (40) to draw air into the housing through the inlet (36, 38, 39, 41) as the balance shaft (28, 30) rotates and expels air/oil to the engine through the outlet (40). The inlet opening (36, 38, 39, 41) and the discharge opening (40) are arranged so as to provide for rapid purging of oil from the housing (10), minimizing oil aeration, heating and motoring losses.</p> |
