    摘要： A mounting support for a catalyst body which is adapted to be installed into an exhaust gas line of an internal combustion engine; the forces necessary for fixing the catalyst body which act in the longitudinal direction are thereby produced by walls of the mounting support which are located in front of and/or to the rear of the catalyst body, as viewed in the longitudinal direction of the mounting support, on that side on which the forces act laterally on the catalyst body; these walls support themselves at a distance from the catalyst body as measured in the longitudinal direction.

    摘要： In an exhaust system for an internal combustion engine, wherein pollutants are removed from the exhaust gases by catalytic conversion, a pinwheel type of deflector positioned within the exhaust flow provides a radially-outwardly deflected swirl flow to the gases as they emanate from an exhaust pipe of one diameter into a canister of larger diameter for housing a catalytic converter. Such flow distribution results in improved catalytic conversion efficiencies obtainable by the converter and reduces its degradation rate inherent with time.

    摘要： A low profile catalytic converter made of sheet metal wherein catalyst material is contained in a space between top and bottom catalyst retaining plates which in turn are located between top and bottom shells to define a structure wherein engine exhaust gases entering at one end of the converter pass through the catalyst material and exit at the opposite end. Sagging of the bottom catalyst retaining plate is avoided by one or more elongated support channels each having a web in face-to-face supporting relation to the bottom shell and upstanding longitudinal sides which fit against and support the bottom catalyst retaining plate at a series of spaced points along their lengths. Each support channel includes a web that is struck upwardly to define a pair of flat portions that fit against and are welded to the bottom catalyst retaining plate, one of these flat portions has fore and aft rigidity while the other has fore and aft flexibility, so that the welds do not break under the temperature gradients and varying thermal expansion conditions of the converter, when used.
