摘要： A cylinder liner (100) is provided that includes a cylinder bore (106) capable of housing a piston (212), a top end (102) having an annular flange (108), a first cylindrical section (114), a second cylindrical section (116), and an annular ridge (112) that separates the first cylindrical section and the second cylindrical section. When employed in a liner bore (210) of an engine block (200), the cylinder liner provides for two channels that allow for coolant to be supplied to the cylinder liner.

摘要： An internal combustion engine (10) having an engine block (12) and one or more cylinder heads (32). The engine block houses a plurality of cylinder liners (14) and includes a cylinder liner coolant jacket (64) below an upper planar surface (30) 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 (60, 62) and one or more downward coolant passages (66) 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.

摘要： A passive diverter fitting (108) for a cooling system (100) of an engine (102) includes a base (320) defining an interior cavity (322), an inlet opening (224) extending through the base that is in fluid communication with the interior cavity, an outlet opening (226) that is in fluid communication with the interior cavity, and a bypass opening (228) that is in fluid communication with the interior cavity. The base is configured to be removably disposed in a cavity of an engine block (238). 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 (240) of the engine block when the passive diverter fitting is disposed in the cavity of the engine block.
