Exhaust gas recirculation device for a motor vehicle

摘要

An exhaust gas recirculation device for a motor vehicle is disclosed with includes an unburnt gas line for guiding an unburnt gas flow and at least one exhaust gas feed line for supplying exhaust gas into the unburnt gas line. At least two discharge openings offset relative to each other in the circumferential direction of the unburnt gas line are provided in the unburnt gas line, by way of which the exhaust gas can be or is supplied to the unburnt gas line.

主权项

1. An exhaust gas recirculation device for a motor vehicle comprising:
a housing having a first inlet port in fluid communication with a first gas feed for supplying an intake gas to the housing, a second inlet port in fluid communication with a second gas feed for supplying a recirculated exhaust gas to the housing, and an exhaust port for exhausting a mixture of the intake and recirculated exhaust gases from the housing; and a mixing device for mixing intake and recirculated exhaust gases, the mixing device having a pipe segment disposed within an interior space of the housing to define a mixing region, the pipe segment having a pipe inlet in fluid communication with the first inlet port, a pipe outlet in fluid communication with the exhaust port and a second gas passage defined between the pipe segment and the housing in fluid communication with the second inlet port, the pipe segment having at least two discharge openings formed therethrough which are offset relative to each other in a circumferential direction of the first gas feed, wherein the first gas feed comprises a first circumferential section which is aligned flush with the second gas feed and the flow cross section of the discharge openings becomes larger the more remote they are from the first circumferential section in the respective circumferential direction.
