Exhaust gas facility for diesel vehicles with an SCR catalytic converter

摘要

The system has parallel lines (2, 3) connected with an engine and a selective catalytic reduction (SCR) catalytic converter (5). An injection device (9) is provided at the line (2) for a reducing agent, and a mixing device (10) is connected upstream of the converter, where the lines end in the device. The device is configured for mixing an exhaust gas stream with the agent from the line (2), and reducing agent-free exhaust gas stream from the line (3). The mixing device has a housing attached to the converter, and a perforated hollow body i.e. tubing section, arranged in the housing.
