<p>The invention relates to a catalytic combustion engine exhaust gas purifier with additional air supply. The exhaust gas purifier comprises a housing structure (1) accommodating an exhaust gas inlet (2), at least one catalyst element (3), means (4) for laminarizing the exhaust gas flow, means (5 and 6) for dividing the housing structure (1) into several chambers (7-9), an exhaust gas outlet (10) and, additionally, means (11) for supplying additional air (17 and 18) into the exhaust gas flow (14 and 15) in the housing structure (1). One or more suction plates (19 and 20) are provided in the chamber (8) after the means (4) laminarizing the exhaust gas flow and at the same time in the vicinity of the means (11) supplying additional air. The suction plates (19 and 20) comprise exhaust gas ports and additional air (17 and 18) ports, and the suction plates (19 and 20) are arranged against the exhaust gas flow (14 and 15) and the additional air flow (17 and 18) so that the additional air is arranged to be sucked through the additional air ports and from the suction plates (19 and 20) into the exhaust gas flow (15) passing through the exhaust gas ports of the suction plates (19 and 20).</p> |
