An apparatus sizes an exhaust component that includes an outer shell that surrounds first and second substrates. At least one sensor hole is formed in the outer shell at a location between the first and second substrates. A first end of the outer shell is surrounded with a plurality of first fingers to size the first end around the first substrate to a first cross-section. At least one first finger has a protruding portion at a first finger distal end that is longer than first finger distal ends of the other first fingers. A plurality of second fingers surrounds the second shell end to size the outer shell about the second substrate to a second cross-section. At least one second finger has a recess portion at a second finger distal end that receives the protruding portion of the at least one first finger.

Apparatus for sizing a component shell having at least two different cross-sections

A method and apparatus forms an exhaust component that includes first and second substrates. An outer shell surrounds the first and second substrates. At least one sensor hole is formed in the outer shell at a location between the first and second substrates. A first end of the outer shell is surrounded with a plurality fingers to size the first end around the first substrate to a first diameter. The plurality of fingers includes an extended finger that is longer than the other fingers such that the extended finger at least partially covers the sensor hole during sizing of the first end. A second end of the outer shell is then surrounded by the fingers to size the second end around the second substrate to a second diameter. The extended finger at least partially covers the sensor hole during sizing of the second end.

An emission abatement device comprises a hydrocarbon trap, a 3-way catalyst downstream from the hydrocarbon trap, and a valve movable to control flow of exhaust gas to the hydrocarbon trap and the 3-way catalyst.
