    摘要: The invention essentially concerns a method for regenerating a device for filtering exhaust gases produced by an engine, said method being of the type whereby the particles, retained on a filtering means of said filtering device, are burnt by the action of a combustion catalyst. Said method is characterized in that it essentially consists in using an ammonium nitrate solution, so as to produce an intimate mixture between the nitrate and the carbon particles and cause said particles to be burnt. The invention also concerns a device for implementing said method, which mainly comprises means for filtering (22) exhaust gases contained in a reaction chamber (18), in the path of the exhaust gas streams produced by an engine (10) and means for injecting the ammonium nitrate solution connected to said reaction chamber (18).

    摘要: The invention relates to a particle filter system for engines and a method for reducing pressure loss in said filter. The system comprises a filter in an exhaust line of the engine, a water injector at the inlet of the filter, a conduit between a water supply source and the injector, an injection pump, pressure sensors at the inlet and the outlet of the filter for determining a pressure loss in the filter, and a control unit for controlling the actuation of the pump. The method comprises detecting a pressure loss between the inlet and the outlet of the filter, injecting pressurized water into the inlet of the filter when the pressure loss reaches a permitted maximum value and controlling the operating conditions required for filter regeneration in order to re-start the soot accumulation process in the filter.
