ABSTRACT:
An electronic control device and method for determining the fuel quantity at which a burner is operated whose exhaust gas mixes with the exhaust gas of an internal combustion engine in an exhaust-gas system in front of a catalytic converter, in which a first oxygen concentration in the exhaust gas of the internal combustion engine is measured spatially before the mixing of the exhaust gas of the burner with the exhaust gas of the combustion engine, a second oxygen concentration in the intermixed exhaust gas is measured, and the fuel quantity at which the burner is operated is determined on the basis of processing the first oxygen concentration and the second oxygen concentration.
