Abstract: A cylinder liner is provided that includes a cylinder bore capable of housing a piston, a top end having an annular flange, a first cylindrical section, a second cylindrical section, and an annular ridge that separates the first cylindrical section and the second cylindrical section. When employed in an a liner bore of an engine bock, the cylinder liner provides for two channels that allow for coolant to be supplied to the cylinder liner.

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.

Abstract: An internal combustion engine having an engine block and one or more cylinder heads. The engine block houses a plurality of cylinder liners and includes a cylinder liner coolant jacket below an upper planar surface of the engine block and in fluid communication with the plurality of cylinder liners. The one or more cylinder heads are attached to the upper planar surface of the engine block and each of the one or more cylinder heads including one or more cylinder head coolant jackets and one or more downward coolant passages extending from the one or more cylinder head coolant jackets to the cylinder liner coolant jacket for delivering coolant from the one or more cylinder head coolant jackets to the cylinder liner coolant jacket.

Abstract: A passive diverter fitting for a cooling system of an engine includes a base defining an interior cavity, an inlet opening extending through the base that is in fluid communication with the interior cavity, an outlet opening that is in fluid communication with the interior cavity, and a bypass opening that is in fluid communication with the interior cavity. The base is configured to be removably disposed in a cavity of an engine block. The inlet opening is positioned to receive coolant when the passive diverter fitting is disposed in the cavity of the engine block. The outlet opening is in fluid communication with the area exterior to the engine block when the passive diverter fitting is disposed in the cavity of the engine block. The bypass opening is in fluid communication with an interior coolant passage of the engine block when the passive diverter fitting is disposed in the cavity of the engine block.
