Abstract

A method for removing solid particulate matter from the exhaust of a diesel engine (62), which comprises passing the engine's exhaust flow through at least a part fo filter means (64) to trap solid particulate matter contained initially in the exhaust, thereby to remove said matter from said exhaust flow, periodically interrupting the exhaust flow through at least said part of the filter means (64), passing, during said interruption, at least one backflush fluid pulse through at least said part of the filter means (64) thereby to disloge from the filter means, and entrain, said solid particulate matter, and transporting said dislodged solid particulate matter to the intake (76) of said engine (62) so that said matter can be combusted in the engine (62), and an apparatus for accomplishing same.
