Abstract

Porous ceramic diesel particulate filters are regenerated to combust accumulated carbon particulates trapped therein through a controlled regeneration process wherein heat is input to the filter at a ramped or staged heating rate below that rate at which the particulate combustion process would proceed so rapidly and extensively that filter temperatures would be raised to filter-damaging levels.
