A stacked plate heat exchanger for a motor vehicle is disclosed. The stacked plate heat exchanger includes a plurality of elongated stacked plates extending in a longitudinal direction and stacked against one another perpendicularly to the longitudinal direction in a stacking direction. First hollow spaces and second hollow spaces are disposed between adjacent stacked plates, through which alternatingly a first medium and a second medium flows. At least one stacked plate has a rib structure disposed on a respective plate surface, structured and arranged to provide a plurality of flow passages within the respective hollow space. The rib structure has a guiding region and two distribution regions. The rib structure differs in the guiding region and in the two distribution regions by shape and size of the plurality of flow passages.

The present disclosure describes an arrangement for a motor vehicle including an internal combustion engine, a heat exchanger for cooling exhaust gas present in the internal combustion engine, and an exhaust system for discharging the exhaust gas. The heat exchanger has a channel system including at least one exhaust gas channel, through which an exhaust path leads, and at least one coolant channel, through which a coolant path of a coolant leads, fluidically separate from the exhaust gas path and arranged in a heat-transferring manner with the exhaust gas path for heat exchange during operation. A cooling gas outlet, opening into the exhaust gas path upstream of the channel system, is provided for introducing a cooling gas into the exhaust gas path upstream of the channel system.

Arrangement with internal combustion engine and heat exchanger

An exhaust gas system for a motor vehicle may include an exhaust gas aftertreatment device communicating fluidically with an exhaust gas evaporation device. The exhaust gas aftertreatment device and the exhaust gas evaporation device may be arranged in one or more housings. A connecting line may be provided to fluidically connect the exhaust gas aftertreatment device to the exhaust gas evaporation device. The connecting line may include a fluid inlet connected to the exhaust gas aftertreatment device and a fluid outlet connected to the exhaust gas evaporation device. An evaporation bypass line may branch off from the connection line at a branching-off point. A valve apparatus may be arranged in at least the connecting line and may be adjustable between a first position to fluidly connect the fluid inlet to the fluid outlet, and a second position to fluidly connect the fluid inlet to the evaporator bypass line.

Exhaust gas system for a motor vehicle

The application relates to a system for using the waste heat of an internal combustion engine through the Clausius-Rankine cycle. Such system prevents operating medium from the Clausius-Rankine cycle from leaking into combustion air or exhaust air. The system has a first flow channel formed by at least one first limiting component and a second flow channel formed by at least one second limiting component. The system has a fluid-conducting connection to the surroundings or to a receiving chamber from the first limiting component and preferably from the second limiting component, so that in the event of a leak the operating medium is conducted into the surroundings or into the receiving chamber.
