Exhaust system

摘要

Embodiments of the invention are directed to an exhaust system for a combustion engine with a bent pipe section conducting an exhaust gas flow. The exhaust system further includes an injector for introducing a liquid reduction agent into the exhaust gas flow, which is connected to the pipe section via a connecting pipe so that the injector can introduce the reduction agent through the connecting pipe into an introduction region of the pipe section into the exhaust gas flow. The risk of a crystallization of the reduction agent can be reduced with a return flow plate, which in the pipe section is arranged upstream of the introduction region.

1. An exhaust system for a combustion engine, in particular of a motor vehicle, comprising:
a bent pipe section conducting an exhaust gas flow, which comprises an inlet region and an outlet region, an injector for introducing a liquid reduction agent into the exhaust gas flow, which is connected to the pipe section via a connecting pipe so that the injector can introduce the reduction agent through the connecting pipe into an introduction region of the pipe section located between inlet region and outlet region in the direction of the outlet region into the exhaust gas flow, a return flow plate, which in the pipe section is arranged upstream of the introduction region, which with its longitudinal direction extends sloped relative to a flow direction in the direction of the outlet region, which comprises the exhaust gas flow in the inlet region and which can be subjected to a lateral exhaust gas flow.
