A system for NO


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 has flowing to the exhaust emission control unit (2). Said exhaust has is heated to a SET temperature by converting hydrocarbons (HCs) metered into the exhaust has flow at two oxidation catalytic Converters (7, 10) series-connected in the flow direction of the exhaust gas.
