Abstract

A method for metering a fuel into at least one exhaust duct of an internal combustion engine and a device for implementing the method. The fuel is converted in an exothermic reaction for achieving a specified setpoint temperature of a component to be heated. The required metering quantity of the fuel is calculated with the inclusion of a model of the exothermic reaction. The method makes it possible to achieve the specified setpoint temperature of the component to be heated or of the exhaust gas in front of the component to be heated using a minimal quantity of fuel.
