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.

Abstract: This paper suggests a procedure for the operation of an internal combustion engine, which has a particle filter arrayed to its emission system, which, during regeneration, is cleansed of its stored particles. This also describes the procedure's comparison of the engine's amount of a load to the load threshold value. It also has a throttle cut-off, which suppresses the fuel supply entirely when the engine's amount of a load is lower than the load threshold value and the engine's revolutions are higher the revolution threshold value. The set load threshold value above null is further dependant on the particle filter's regeneration signal. These procedures, based in this invention, are to prevent the overheating of the particle filter during its regeneration.
