Abstract
An improved method for performing a conditioning process for a particulate filter, preferably adapted for an aftertreatment system arranged downstream of an internal combustion engine. The proposed method provides for conditioning of a filter under controlled conditions such that the filter may reach a desired operation state in a more efficient and faster manner. Further, the proposed method also advantageously provides for maintaining the desired operation state, in which the filtration capacity may be at a usable level.
