Patent ID: 6865884

Claim:
An operating method for an internal combustion engine which operates with an exhaust-gas aftertreatment system in which a plurality of operating programs, which can be used in a step sequence, are used for the exhaust-gas aftertreatment system operating with a particle filter, the particle filter being regenerated as a function of its loading and monitored for a limit loading being exceeded, comprising: using a support program for regeneration of the particle filter with a temperature increase of the exhaust gases fed to the particle filter, and using a reactivation program for components which are associated with the exhaust-gas aftertreatment system in addition to the particle filter when the successive, preceding and successful activations of the support program occur at a frequency greater than a predetermined limit frequency, wherein the components which are associated with the exhaust-gas aftertreatment system for which the reactivation program is used include at least one of a catalytic coating, a fuel additive supply device, and an internal combustion engine exhaust gas heating device.
