In order to reduce the combustion residues, such as unburnt hydrocarbons, carbon monoxide and soot, occurring in all current combustion engines, such a temperature is created in the afterburner whilst increasing the pressure by means of a retaining plate and limiting a passage that these substances can be afterburnt. Constant combustion conditions are thereby produced despite the variable engine speed and hence variable exhaust gas volumes and temperatures. At low exhaust gas temperatures an electrically operated exhaust heating is also switched on, which prevents any accumulation of solid combustion residues. A reactor part contained in the afterburner, through which a plurality of tubes passes, acts as an energy reservoir and is thus capable of imparting energy to contacting exhaust gas molecules.
