摘要：
The present invention relates to a method for regenerating particulate filters for reduction of harmful emissions of exhaust gases from internal combustion engines, and an apparatus for carrying out said method.
The method according to the present invention envisages nebulizing, by means of a suitable nozzle and by pulsed injection, a suitable amount of oxidizing reagent in aqueous solution directly onto the filtering surface of the particulate filter, in such a way that droplets of average diameter below 500 micron reach the filtering surface in the liquid state. The present invention further relates to an apparatus for carrying out said method.
