Exhaust fumes reducing product mixing chamber for catalytic converter of vehicle i.e. motor vehicle, has reducing product injection device injecting reducing product at periphery of zone of chamber

摘要

The chamber (221) has a reducing product injection device (30), where a perforated wall (230) separates the chamber into a zone (227) and another zone. The perforated wall has a median part (226) forming a return pipe in direction of an upstream of flow of exhaust fumes. The injection device injects the reducing product at a periphery of the former zone of the chamber, and is equipped at the periphery of the former zone of the chamber. A case (222) is provided with reduction catalyst. Independent claims are also included for the following: (1) a catalytic converter, comprising an exhaust fumes reducing product mixing chamber (2) a vehicle.
