Abstract

An internal combustion engine exhaust gas treatment device (11) in which exhaust gases from an engine are passed through a non conductive separation chamber (15) having corona discharge means therein comprising a plurality of tubular electrodes (21) bundled together and each tubular electrode has an oppositely charged electrode (23,24) extending coaxially therein so that particulates in the exhaust gas are ionized and charged particulates migrate to the electrodes (21). The oppositely charged electrodes (23,24) within the tubes (21) are supported and interconnected by conductive support frames (25) located one at each end of the bundled tubes and cleaning means (35) mounted on the frames hinder the agglomeration of charged particles.

9. An exhaust gas treatment device as claimed in any one of Claims 1 to 8, wherein each tubular electrode is perforated allowing exhaust gases to flow over both inner and outer surfaces of the tubular housing.
10. An exhaust gas treatment device as claimed in any one of claims 1 to 9 wherein each cleaning means is a spinner rotatably mounted on its respective support frame such that exhaust gases move the spinner relative to the frame.
11. An exhaust gas treatment device as claimed in claim 10 when dependant upon Claim 3, wherein each spinner is mounted on a ceramic bearing in turn mounted on the respective radial arm .
12. An exhaust gas cleaning device as claimed in Claim 11, wherein at least one ceramic bearing locates in a co-operating hole in the ceramic housing to locate the frame.
13. An exhaust gas cleaning device as claimed in any one of claims 1 to 12 , wherein operation of the corona discharge means is by control means connected to a conductive support frame and to the bundle of tubes,
14. An exhaust gas cleaning device as claimed in claim 14, wherein the chamber has a tubular ceramic housing which is held in a tubular metal container and the control means is located in an aperture in a wall of the container .
