摘要： An aftercooler mounting and sealing system for use with an internal combustion engine is disclosed including an intake manifold (14), a distribution manifold (16) disposed downstream of the intake manifold (14), and an aftercooler (12) clamped between the intake manifold (14) and the distribution manifold (16). Resiliently compressible U-shaped seals (32, 34) are provided between the inlet (24) of the aftercooler (12) and the intake manifold (14) and between the outlet (26) of the aftercooler (12) and the distribution manifold (16) to effectively seal against leakage of charged intake air from the manifold joints. The clamp load across the resiliently compressible seals (32, 34) is selectable independent of the clamp load across the intake manifold (14) and the distribution manifold (16).

摘要： An internal combustion engine (10) includes a cylinder block (12) with a cylinder bore (20). A cylinder liner (14) within the cylinder bore (20) has a distal end (44) with an outside diameter (56). A cooling ring (16) has a first inside diameter (58), a larger second inside diameter (60) and a plurality of radial coolant passages (74). The first inside diameter (58) is positioned closely adjacent to the outside diameter (56) at the distal end (44) of the cylinder liner (14). The second inside diameter (60) is radially spaced apart from and defines an annular coolant channel (72) with the outside diameter (56) of the cylinder liner. The radial coolant passages (74) are in fluid communication with the annular coolant channel (72).

摘要： An internal combustion engine (10) includes a cylinder block (12) with a cylinder bore (24). A cylinder head (14) is attached to the cylinder block (12) and covers the cylinder bore (24). A cylinder liner (16) within the cylinder bore (24) has a distal end (44), an inside diameter (58), and an annular recess (62) extending radially outwardly from the inside diameter (58) at the distal end (44). A piston (18) is reciprocally disposed within the cylinder liner (16). An annular scraping ring (20) positioned in the annular recess (62) has an inside diameter (64) which is smaller than the inside diameter (58) of the cylinder liner (16) and is configured to scrape deposits from the piston (18). The scraping ring (20) extends axially beyond the distal end (44) of the cylinder liner (16). An annular sealing ring (22) is separate from, located by and positioned radially outwardly adjacent to the scraping ring (20). The sealing ring (22) directly engages and seals between the cylinder head (14) and the distal end (44) of the cylinder liner (16).

摘要： A thermally conductive sealing system for the cylinder head joint (11) of an internal combustion engine (10) is disclosed comprising a spacer plate (24) clamped in direct contact between the cylinder head (12) and the cylinder block (14) and a plurality of discrete fluid gaskets (67, 70) disposed across the spacer plate (24) and clamped between the cylinder head (12) and cylinder block (14). The flange (22) of a cylinder liner (18) is received in a bore (26) of the spacer plate (24) and a combustion gas seal or 'fire ring' (32) is clamped in the bore (26) between the cylinder head (12) and the cylinder liner flange (22). The combustion gas seal (32) includes a malleable sealing ring (42) for sealing between the cylinder head (12) and the cylinder liner (18) and a hardened backing ring (44) for supporting the sealing ring (42). The plurality of discrete fluid gaskets (67, 70) includes a removable lifter compartment gasket (70) including sealing elements (78, 80) attached across a substrate (71) and a plurality of coolant ferrules (67) for sealing across coolant ports (60, 62) and around cylinder head bolts (16).
