Abstract: An internal combustion engine includes a cylinder block defining at least one cylinder, and a cylinder head coupled to the cylinder block. An exhaust manifold is coupled to the cylinder head and configured to receive exhaust gas from the cylinder head. The exhaust manifold includes a water jacket tube defining a plurality of liquid coolant passages and an exhaust tube received within the water jacket tube. The exhaust manifold also includes an air gap between the exhaust tube and the water jacket tube. A support mat is positioned in the air gap and compressed between an outer surface of the exhaust tube and an inner surface of the water jacket tube.

Abstract: A panel assembly includes a panel member having a mounting side and at least one elongated member. The at least one elongated member includes a mounting edge, a second edge opposite the mounting edge of the at least one elongated member, and a plurality of first spaced apart openings. The panel assembly further includes at least one elongated intersecting member. The at least one elongated intersecting member includes a mounting edge, a second edge opposite the mounting edge of the at least one elongated intersecting member, and a plurality of second spaced apart openings. Further, one of the at least one elongated member and the at least one elongated intersecting member includes at least one slot, the at least one elongated member and the at least one elongated intersecting member intersecting at the at least one slot.

Abstract: An internal combustion engine includes a cylinder block defining at least one cylinder, and a cylinder head coupled to the cylinder block. A modular exhaust manifold is coupled to the cylinder head and is configured to receive exhaust gas from the cylinder head. The modular exhaust manifold includes a plurality of exhaust manifold segments coupled together along a common axis. Each of the exhaust manifold segments includes a segment of a water jacket tube defining a plurality of liquid coolant passages and a segment of an exhaust tube received within the water jacket tube segment. A joint between adjacent exhaust manifold segments includes a first sealing member configured to seal the exhaust tube at the joint and a second sealing member configured to seal at least one of the liquid coolant passages at the joint. The first and second sealing members are supported on and movable with different components.
