Abstract:
1. A method for cleaning particle filters in exhaust gas systems of combustion engines, comprising: exposing an opening leading into an interior of a housing, the opening positioned upstream of the particle filter to be cleaned, inserting a spray nozzle into the interior of the housing, through the opening, so that nozzle openings of the spray nozzle oppose an upstream end face of the particle filter through which exhaust gas flows during operation of the combustion engine; and spraying a noncombustible, ash-free cleaning fluid into the particle filter by the spray nozzle at a pressure of from 5 to 12 bar, across an area of said filter through which the exhaust gas flows during the operation of the combustion engine, such that the cleaning fluid flows from the upstream end face of the particle filter to a downstream end face thereof, in a quantity corresponding approximately to half the volume of the particle filter such that the interior of the particle filter is soaked.
