Abstract
An assembly for particulate filter traps in which engine exhaust particulates are deposited for the treatment of internal combustion emission, includes a filter trap support containing a plurality of individual particulate filter traps arranged side-by-side and parallel to the direction of exhaust gas flow therethrough. An inflow housing overlying the trap support is removable for inspection of the filter traps, and a sectioned cover of the trap support underlying the removable housing permits one or more individual traps to be inspected and separately replaced.
