Claims15
Method for cleaning a spray electrode of an electrofilter with a cleaning body, said electrofilter suitable for use with an internal combustion engine, comprising the steps of
- providing a two-stage spray electrode having a first stage for forming a corona, said first stage terminating in a free end, and
- wiping only the first stage of the spray electrode with the cleaning body by moving the cleaning body along the first stage, thereby cleaning the spray electrode.
An electrofilter, suitable for use with an internal combustion engine, having a movably mounted cleaning body, comprising a two-stage spray electrode having a first stage terminating in a free end for generating a corona, wherein said first stage has a diameter smaller than the diameter of a second stage and said second stage has a length greater than the length of said first stage, wherein the cleaning body is adapted for movement along said first stage to clean the spray electrode.
