ABSTRACT:
Trap muffler apparatus with bypass to a common reactive acoustic element is disclosed. Bypass structure varies from external bypass to a common acoustic element to annular bypass of the ceramic filter to axial bypass through the middle of an annular ceramic filter. Forward or reverse regeneration are possible. Bypass to atmosphere without filtration is avoided with dual in-line traps or with the segmented trap and control of exhaust gases to traps not being regenerated.
