Abstract

1. Apparatus for eliminating soot or the like from the exhaust gases of an internal combustion engine, more particular a diesel engine, comprising a micro-wave source (18), a cavity resonator (1) constituting an intermediate member coupled to the exhaust-gas pipe (15) and containing a metal grating (14) in each of its two exhaust-gas openings (6, 8) disposed in the end faces (2, 3), and a tubular soot filter (20) made of dielectric material and disposed in the region of maximum energy density of the electromagnetic field in the flow path of the exhaust gases in the cavity resonator (1), one exhaust-gas opening (6) being situated radially inside the filter cross-section, characterised in that the tubular soot filter (20) extends from one end wall (2) to the other end wall (3) of the cavity resonator (1), the other exhaust-gas opening (8) is situated radially outside the filter cross-section, and the metal gratings (14) are honeycomb gratings and extend from the exhaust-gas openings (6, 8) for a preset axial minimum length into the exhaust-gas pipe (15).
