CATALYTIC UNIT FOR EXHAUST NEUTRALIZER AND METHOD OF MAKING SAME Russian patent published in 1995 - IPC

FIELD: engine engineering. SUBSTANCE: catalytic unit has roll made as a corrugated heat resistance steel belt. The belt starts at the center of the unit and is wound in two layers 2,3 to provide the tight roll. Hollows 4 and ridges 5 of the belt corrugations are arranged at an angle or over the arc or break line to the edge of the belt. The ridges of one layer is mounted for crossing the hollows of adjacent layer to form gas passages. The surface of the passages is coated with a catalyzer. Ridges 5 and hollows 4 of the adjacent layers are forced into each other in cross points. EFFECT: enhanced efficiency. 9 cl, 4 dwg
