Abstract
A procedure for the operation of an internal combustion engine is disclosed, in whose exhaust gas area a particle filter is arranged which is freed from the stored particles during a regeneration. A measure for a load of the combustion engine is compared to a load threshold value. An overrun cut-off, at which the fuel metering is completely suppressed, is carried out if the measure for the load falls below the load threshold value and if the engine speed of the combustion engine lies above an engine speed threshold value. The load threshold value that has been determined to a value higher than zero is further dependant on the particle filter's regeneration signal. The procedure aims to prevent the overheating of the particle filter during its regeneration.
