Exhaust gas system for passenger car, has injector angularly ending at axial direction of inner pipe that is arranged in region of corrugated pipe, and mixing device arranged at inner pipe for mixing reducing agent with exhaust gas

摘要

The system (10) has two pipes (12, 16) and a corrugated pipe (14) surrounding an inner pipe (18) in which exhaust gas flows in an axial direction. An injector (22) injects a reducing agent (24) into the inner pipe, where the reducing agent is provided for reducing nitrogen monoxide to the nitrogen. The injector angularly ends at an axial direction of the inner pipe that is arranged in a region of the corrugated pipe. A mixing device (30) is arranged at the inner pipe for mixing the reducing agent with the exhaust gas.
