Abstract
A method and apparatus for cleaning of a soot filter in the exhaust line of a diesel engine with a combustion chamber placed in front of the soot filter where a fuel nozzle and an adapted electrical ignition mechanism is built in thereby enabling an after burning of the exhaust without secondary air. The exhaust in the combustion-chamber is mixed with the fuel, which is injected through the fuel nozzle, and ignited by an ignition-device with the existing portion of the unburned oxygen. The hot exhaust effects the burn down of the accumulated soot in the soot filter.
