Definitions
- the particulate filter cleaning agent which is liquid in the reservoir for storage and then expands in the interior of the particulate filter into a foam, is almost completely filled and thus completely wetted with a small amount of cleaning agent and thus cleaned in all areas.
- the generation of the foam can be done simply by the physical expansion of an overpressure area in the means for transport in a larger area with lower pressure in the interior of the particulate filter in a simple manner.
- the means of transport extends only to the interior and is therefore not polluted or may not break off in the interior and thus endanger the function of the particle filter.
- the pressure to be used is relatively low and secured by the pressure reducer, so that no danger can arise during operation.
