Internal combustion engine, has mixing device comprising heating device formed by flow conducting surface that projects into concavely curved surface of mixing device, where concave surface forms separating edge at downstream end

摘要

The engine (1) has an exhaust line (2), and an exhaust gas aftertreatment device (3) i.e. selective catalytic reduction-catalytic converter, arranged in the line. A metering device (4) is arranged upstream of the aftertreatment device and provided introducing additive into exhaust gas flow (S). A mixing device (5) has a heating device that is formed by a flow conducting surface for the exhaust gas flow. The conducting surface projects into a concavely curved conducting surface of the mixing device, where the concave surface forms a separating edge at a downstream end.
