ABSTRACT:
A device for the after-burning of combustible components of engine exhaust gases, particularly for mounting on an engine block of an Otto engine, comprises a reactor housing which has an interior elongated reaction chamber. The reaction chamber is divided by a perforated bottom plate which extends across the reaction chamber and divides it into first and second chamber portions. An exhaust gas conduit is connected into the first chamber portion along with a secondary combustion air supply conduit, and the second chamber portion is connected to a treated gas discharge conduit for conducting away from the gases. The exhaust gas conduit is made very short and it has a flange thereon for mounting the device directly on the combustion engine block. The plate is perforated, and it includes one or more plate portions which permits the portions to be displaced relatively in order to accommodate any thermal expansion and contraction. In a similar manner, the housing itself is made of an inner shell portion, having parts which are relatively movable, and which is covered by an outer shell with insulation disposed therebetween.
