Abstract
(DE)
Beschrieben ist ein Verfahren zum Zuführen von thermischer Energie in ein in den Abgasstrang einer Brennkraftmaschine eingeschaltetes Abgasreinigungsaggregat (2) durch Erwärmen des das Abgasreinigungsaggregat (2) anströmenden Abgases. Dieses wird auf eine SOLL-Temperatur erwärmt. Bei diesem Verfahren wird das von der Brennkraftmaschine aus gestossene Abgas durch Konvertieren von in den Abgasstrom dosierten Kohlenwasserstoffen (HC) an zwei in Strömungsrichtung des Abgases hintereinandergeschalteten Oxidationskatalysatoren (7, 10) auf die SOLL-Temperatur erwärmt.
(EN)
The invention relates to a method for feeding thermal energy into an exhaust emission control unit (2) connected in the exhaust gas system of an internal combustion engine by heating the exhaust gas flowing to the exhaust emission control unit (2). Said exhaust gas is heated to a SET temperature. In said method, the exhaust gas discharged from the internal combustion engine is heated to the SET temperature by converting hydrocarbons (HCs) metered into the exhaust gas flow at two oxidation catalytic converters (7, 10) series-connected in the flow direction of the exhaust gas.

L'invention concerne un procédé pour alimenter en énergie thermique une unité d'épuration de gaz d'échappement (2) montée dans le système d'échappement d'un moteur à combustion interne en chauffant les gaz d'échappement affluant dans l'unité d'épuration de gaz d'échappement (2). Ceux-ci sont chauffés à une température de consigne. Selon ce procédé, les gaz d'échappement expulsés du moteur à combustion interne sont chauffés à la température de consigne par conversion d'hydrocarbures (HC) dosés dans le courant de gaz d'échappement sur deux catalyseurs d'oxydation (7, 10) montés l'un derrière l'autre dans le sens d'écoulement des gaz d'échappement.
