摘要:
The invention relates to a motor vehicle (20) which comprises a diesel propulsion engine (21) whose exhaust circuit (29) is provided with a gas cleaning device (R) which is discontinuously regenerable. The inventive motor vehicle is characterised in that a fuel evaporation unit (10) connected to a fuel tank (23) of the vehicle is mounted prior to said gas cleaning device (R) and is used for enriching the exhaust gas of the engine with a fuel vapour (11), and in that the fuel evaporation unit (10) comprises a fuel evaporator (6) in the form of a heat exchanger (12) which is exposed to the exhaust gas flow and comprises a fuel supply (13), the output for the fuel vapour (14) and an auxiliary oxidation catalyst (2) disposed prior to the heat exchanger (12), and also in that the content of unburned diesel fuel in the exhaust gas supplied to the auxiliary oxidation catalyst (2) is controllable with the aid of an enriching unit (15,15').

The invention relates to a fluidic switching element consisting of a feed channel (1), a Coanda tulip (5), at least two outlets (11, 12) and a displacement body (6) that is arranged in the area of the Coanda tulip (5) and is provided with an essentially even flow surface (7). A casing (8) is joined to said surface (7) in the direction of flow. The transitional area between the flow surface (7) and the casing (8) is defined by a separating edge (15).

The invention relates to a device for stabilising the flow in the exhaust line of an internal combustion engine, especially at the exhaust-end exit of an exhaust turbocharger connected downstream of an internal combustion engine. The device consists of a guide plate (3, 8), comprising a plurality of web plates (6) which extend in the direction of flow, crosswise to the exhaust pipe (1).
