Abstract: The invention relates to a process for heating a catalytic converter, a nitric oxide storage catalytic converter and/or particle filter in particular mounted in an exhaust system of a diesel internal combustion engine of a vehicle, to a desulfation and/or decarbonization temperature, a process in which the catalytic converter is heated to a desulfation and/or decarbonization temperature at the beginning of the desulfation and/or decarbonization phase as regeneration phase. A rich exhaust gas flow is delivered periodically to the catalytic converter for the purpose of direct heating of this catalytic converter to a regeneration temperature, in such a way that the unburnt exhaust gas components, hydrocarbons and carbon monoxides in particular, react to the oxygen stored in the catalytic converter and the thermal energy released in the process heats the catalytic converter to a regeneration temperature.
