Abstract:
1. A method for regeneration, the method comprising the following steps: providing a combustion engine arrangement having a combustion engine, an exhaust-gas after treatment device, and a carbon particulate filter provided in an exhaust passage of the combustion engine, switching the combustion engine arrangement to a heating operation for increasing the exhaust-gas temperature, which is suitable to heat the exhaust-gas to a carbon particulate ignition temperature, determining and monitoring a specific energy input as an energy input per carbon particulate mass necessary for regeneration, the specific energy input based on an operation condition of the combustion engine arrangement, and heating the exhaust-gas to the carbon particulate ignition temperature and regenerating the carbon particulate filter by igniting the carbon particulate using the heated exhaust-gas in response to the specific energy input falling below a threshold value for the specific energy input.
