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.

Abstract: A fluid system includes a housing having a valve bore, a fluid supply conduit, and a valve positioned in the valve bore and defining a valve axis. The valve has a first outer sealing surface, a second outer sealing surface, and an inner surface forming a fluid passage extending between a fluid inlet fluidly connected to the fluid supply conduit, and at least one fluid outlet spaced axially from the first outer sealing surface and the second outer sealing surface. A thermoactuator is coupled to the valve and exposed to a flow of fluid from the fluid supply conduit. The working fluid in the fluid system may include engine oil.
