Abstract
In an operating method for internal combustion engines which operate with exhaust-gas aftertreatment systems, in particular diesel internal combustion engines, a plurality of operating programs are used. The first of these programs, as an initial stage, works on the basis of automatic regeneration. The second of these programs provides measures which assist regeneration, for example by increasing the exhaust-gas temperature, in the event of conditions which are unfavourable for regeneration, for example on account of unfavourable driving cycles. The third of these programs has the purpose of reactivating the damaged components in the event of non-irreversible damage to the components of the exhaust-gas system.
