- an inner member positioned coextensive with the tubular body having an air-pervious portion and an end portion, said end portion being substantially air-impervious and including an aperture proximate the ignition means, said end portion diverting most of the vaporized fuel/air mixture through said air-pervious portion of said inner member;
- an outer member, positioned coextensively with the tubular body and concentrically disposed about said inner member, said outer member having an air-pervious portion;
- and
- a catalytic substrate disposed between said air-pervious portions of said inner and outer members.
