Abstract
An engine includes a cylinder block having formed therein a plurality of cylinders, a main oil gallery, and a spray jet gallery. A cross-hole is fluidly connected to the main oil gallery and extends to the spray jet gallery. Oil spray jets are each fluidly connected to one of a plurality of oil feed holes fluidly connected to the spray jet gallery. An oil admission valve, which can be hydraulically actuated or electrically actuated, is supported in the cylinder block and movable between a closed position to block the spray jet gallery and each of the oil feed holes from the cross-hole, and an open position.
