ABSTRACT:
The exhaust gas catalytic converter (1) with an ordered substrate structure (10) for catalysing material comprises layers (13) with parallel channels. The layers are substantially parallel to the direction (15) of main flow of the exhaust gas. The cross-sectional surfaces of the substrate structure along the direction of main flow has, according to the invention, at least partly variable area and/or variable shape; the channels make with the direction of main flow and angle between about 10.degree. and 70.degree. and the channels in adjacent layers are open towards each other and cross each other. The exhaust gas catalytic converter according to the invention enables its shape to be adapted to the conditions of small space.
