Abstract of the Disclosure Separate exhaust pipes each receive exhaust gases from a plurality of cylinders of an internal combustion engine. The exhaust pipes merge into a common outlet pipe delivering exhaust gases into a first reaction chamber and then into a second reaction chamber enclosing the first reaction chamber. The second reaction chamber also encloses the exhaust pipes and outlet pipe. The cross section areas of the exhaust pipes, discharge pipe and continuing passageway through the first reaction chamber are substantially the same in effective cross section area to avoid temperature drop in the exhaust gases due to expansion. Oxygen-rich exhaust gases from the engine are held at a high temperature for long residence time to oxidize HC and CO and thereby minimize the quantity of these pollutants discharged into the atmosphere.
