Abstract: The present invention relates to a heat exchanger for exhaust gas cooling, in particular for motor vehicles. The heat exchanger includes a flow duct which is formed from heat exchange tubes being arranged in parallel to one another, and through which the exhaust gas to be cooled can flow and around which a liquid coolant can flow, and secondly includes a housing having a housing wall and tube bottoms. The housing wall and the tube bottoms delimit a flow chamber for the coolant. The heat exchange tubes being arranged so as to form a tube bundle are formed with straight sections and deflection zones, wherein the heat exchange tubes in at least two deflection zones sweep an angle of at least 90°.

Abstract: A device of a system for air ducting of an internal combustion engine in a motor vehicle with a turbocharger arranged between an exhaust gas line and an intake line. The device includes a high pressure flow pathway with a valve branching from the exhaust gas line between the internal combustion engine and a turbine side of the turbocharger, a low pressure flow pathway with a valve branching in the flow direction of the exhaust gas downstream from the turbine side of the turbocharger, and an exhaust gas heat exchanger. A first flow pathway with a valve and a second flow pathway with a valve merge into a mouth region with a third flow pathway. At least one section of the high pressure flow pathway, the low pressure flow pathway, the flow pathways, and the exhaust gas heat exchanger are integrated inside a housing formed as a continuous compact unit.

Abstract: An assembly and method for operating actuators, the assembly including a control device with at least a first control device part and a second control device part, wherein the first control device part is connected at least indirectly to a first actuator and the second control device part is connected at least indirectly to a second actuator. The method including a control device provided with a first control device part and a second control device part, wherein the first control device part controls a first actuator and the second control device part controls a second actuator simultaneously, wherein control is accomplished wherein at least a first condition, in which the first and second actuators are closed simultaneously, and a second condition, in which the first actuator is closed and the second actuator is opened or the first actuator is opened and the second actuator is closed, can be controlled.
