Abstract:
A system and method are provided for increasing heating of engine oil during a cold start. In one example, engine oil is returned directly to the oil pump inlet, thus bypassing the sump. In this way, a smaller volume of oil receives more heat and is used for lubricating engine components during a cold start, thus providing reduced friction earlier than otherwise possible.
