Abstract (en)
[origin: EP2392790A1] A system for regenerating a particulate trap in an exhaust system of an internal combustion engine and including a wall-flow particulate trap having a plurality of porous walls for filtering engine exhaust and removing particulates therefrom to form a particulate cake on the porous walls, a valving mechanism downstream of said trap for periodically creating a reverse pressure throughout said trap, a reversing apparatus operative after the reverse pressure is created for periodically creating a substantially instantaneous reverse pressure drop across the porous walls of said trap to dislodge accumulated particulate cake and causing the filtered exhaust gas to flow back through the porous walls to remove the dislodged particulate from said trap, and controls for starting and stopping a regeneration cycle.
