    Abstract: The present invention relates to an exhaust-gas recirculation cooler (7) for an internal combustion engine system (1), which cooler has a heat exchanger (9) with a housing (10) and at least one flange (14). An installation space-saving design and/or an increased efficiency of the exhaust-gas recirculation cooler (7) results from the fact that the at least one flange (14) has two flange exhaust-gas openings (15) and two flange coolant openings (16), and the housing (10) has, for the respective flange exhaust-gas opening (15), an associated housing exhaust-gas opening (17) and, for the respective flange coolant opening (16), an associated housing coolant opening (18), wherein at least one of the housing coolant openings (18) is arranged on the side of the housing (10) that faces the associated flange coolant opening (16). The invention further relates to an internal combustion engine system (1) having such an exhaust-gas recirculation cooler (7).

    Abstract: A marine outboard motor (2) has an internal combustion engine (100) including an engine block (110), at least one cylinder (114), an air intake (120) configured to deliver a flow of air to the at least one cylinder and an exhaust conduit (130) configured to direct a flow of exhaust gas from the at least one cylinder. The internal combustion engine also includes an exhaust gas recirculation system (140) configured to recirculate a portion of the flow of exhaust gas from the exhaust conduit to the air intake. The exhaust gas recirculation system comprises a heat exchanger (150) for cooling recirculated exhaust gas. The heat exchanger has a fixed part which is integral to the engine block and a removable part which is mounted on an external surface of the engine block. In this manner, the heat exchanger is removably integrated into the engine block.

    Abstract: A heat exchanger is provided. The heat exchanger includes a bundle of elongated tubes having open ends for a first fluid, a pair of manifolds and a housing. The pair of manifolds located on both sides of the open ends of the elongated tubes. The housing is configured to form a conduit for the second fluid and at least partially encapsulating the elongated tubes. The housing includes an inner surface facing the elongated tubes and at least one connection point formed by two perpendicular portions of the housing. Further, one of the perpendicular portions has a bent section forming the connection point by parallel arrangement with the other portion. The heat exchanger further includes at least one sealing portion located at least within the housing, so that the sealing portion overlaps at least portion of the connection point adjacent to at least one manifold.
