Abstract: A cooler arrangement for connection to an exhaust gas manifold or to an exhaust gas outlet of an engine block of an internal combustion machine includes an exhaust gas cooler comprising at least one exhaust gas duct and a coolant jacket. The exhaust gas cooler is configured to be mounted at the engine block or at the exhaust gas manifold. An exhaust gas recirculation valve is configured to regulate an exhaust gas flow. An actuator is disposed on a side of the exhaust gas recirculation valve opposite the exhaust gas cooler. The actuator is configured to actuate the exhaust gas recirculation valve. A coolant duct segment is arranged between the exhaust gas manifold or the engine block and the actuator. The coolant duct segment is fluidically connected to the coolant jacket.

Abstract: An exhaust gas cooling module for an internal combustion engine includes an exhaust gas recirculation valve comprising an exhaust gas recirculation valve housing having an inlet, an exhaust gas heat exchanger, an exhaust gas non-return valve comprising an exhaust gas non-return valve housing, and two exhaust gas channels. The two exhaust gas channels are arranged in the exhaust gas cooling module so as to separately extend from the inlet of the exhaust gas recirculation valve housing to the exhaust gas non-return valve housing via the exhaust gas heat exchanger.

Abstract: A heat exchanger for an internal combustion engine includes a channel configured to have a fluid to be cooled flow therethrough, a coolant channel, and a separating wall configured to separate the coolant channel from the channel. The separating wall comprises knobs on a surface facing the coolant channel. The knobs are arranged on the surface so as to form first zones comprising the knobs and second zones comprising a smooth surface without the knobs. The first zones and the second zones are arranged relative to each another so as to from zones with a different flow resistance.

Abstract: The invention relates to a controllable two-way valve (1), in which a valve rod (3) is connected in a permanent manner to at least two valve members (4, 5, 6, 24, 25; 39, 40), the valve rod (3) being actuated by means of an actuator (2). The housing (7) comprises an inlet (8; 4) or outlet and two corresponding outlets (9; 32; 42), (10; 28; 43) or inlets. According to the invention, the two valve members (4, 5, 6; 24, 25; 39, 40) correspond with at least two valve seats (12, 17, 22; 29, 37, 38; 46, 47) and the two or more valve members (4, 5, 6; 24, 25; 39, 40) have three control surfaces (11, 13, 18; 26, 27, 31; 44, 45, 48). The invention thus provides a dirt-resistant valve, which is easy to operate, has fixed valve members and does not require additional equipment. Said valve permits both the inlet to be completely blocked and the two outlets to be controlled independently of one another.

Abstract: An exhaust gas recirculation system for a combustion engine is proposed that includes all important functions within a housing. For this purpose an exhaust gas recirculation valve, an exhaust gas cooling device with a heat exchanger unit, as well as a bypass channel with a bypass flap likewise embodied in the housing, form a unit. In addition, the exhaust gas recirculation valve in the area of its valve seat is cooled by the coolant of the exhaust gas cooling device. Thus a solution is proposed that, in comparison with known exhaust gas recirculation systems, greatly reduces construction space and weight, at the same time features low-cost assembly, and is also to be implemented very cost-effectively by the possibility of producing all housing parts in the die-casting method.

Abstract: Exhaust gas feeding device for a internal combustion machine for introducing exhaust gas into a suction channel section of an intake manifold through at least one opening, having an exhaust gas feed section, an exhaust gas feedback valve and an exhaust gas introduction plate that forms a annular channel in the wall region of the suction channel section, wherein the exhaust gas introduction plate is designed as a stamped part with formable webs in such a manner that the webs define a ring channel annular channel with openings in the built-in state of the exhaust gas introduction plate.

Abstract: An air intake duct system for internal combustion engines, and in particular for V-engines, comprises a plurality of air intake ducts (10, 12). Each air in-take duct is formed by two duct portions (18), and (20) and (22), respectively. The second duct portions (20, 22) are arranged to swivel about a swivelling axis (34) and (36), respectively, for varying the length of the air intake duct. According to the invention the two swivelling axes (34, 36) are supported in a common bearing part (44) which comprises two swivelling axis bearings each provided for one of the two swivelling axes (34, 36).
