Beschreibung
Zusammenfassung:	The present invention relates to a method and an apparatus for controlling regeneration of a particle filter. The method and the apparatus are used for controlling a particle filter in a waste gas passage of a combustion engine, wherein the air input passage of the combustion engine is provided with an air damper and a waste gas feedback valve, between the air input passage and the waste gas passage there is provided the waste gas feedback valve, and the combustion of the particles in the particle filter is triggered and monitored through intervening the air flow and the attaching injection fuel. It is proposed that the regeneration process can be divided into a regeneration stage and an expanded regeneration stage, the regeneration process is used for rapidly oxidizing carbon black particles in the particle filter, the re-injection is given up in the expanded regeneration stage, just like the application in the traditional regeneration stage. The method and the apparatus can shorten the regeneration duration
