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.
