Abstract:
1. A catalytic converter assembly for a motor vehicle comprising: an external shell formed of two halves including a first half and a second half, the external shell halves mating together along first perimeter flanges to form an inlet end, an outlet end and a center portion between the inlet and outlet ends, the inlet and outlet ends adapted for connection with components of an exhaust system of the motor vehicle, a catalyst substrate that is enclosed within the center portion of the external shell, a first internal shield formed of two halves including a first half and a second half, the first internal shield halves mating together along second perimeter flanges and each of the halves including an end flange and at least one local tab that extends axially from a circumferential edge of the first internal shield and extends laterally along said edge a short circumferential length parallel to an adjacent contour of the external shell, which tab contacts an external shell half enabling a connection of a first internal shield half to an external shell half, with the end flange contacting the external shell halves at their inlet ends and the tabs contacting the external shell center portion, and a second internal shield formed of two halves including a first half and a second half, the second internal shield halves mating together along third perimeter flanges and each of the halves including an end flange and at least one local tab extends axially from a circumferential edge of the second internal shield and extends laterally along said edge a short circumferential length parallel to an adjacent contour of the external shell, which tab contacts an external shell half enabling a connection of the second internal shield half to an external shell half, with the end flange contacting the external shell halves at their outlet ends and the tabs contacting the external shell center portion.
