Abstract
A device for re-treating exhaust gases of an internal combustion engine is proposed, in which to promote the efficiency of a downstream reducing catalytic converter, fuel is metered via a metering valve and introduced into the exhaust system via an evaporator device. A metal sheath is provided with a sheathed glow-plug element that is used as the evaporator device and via a flow opening on a face end introduces an evaporated reducing agent into the exhaust gas stream.
