ABSTRACT:
An exhaust processor having a housing and a diesel particulate trap or filter retained within the housing is provided with a particulate trap seal. The housing includes an inlet for introducing a combustion product into the housing and an outlet for exhausting combustion product from the housing. The trap includes a monolithic cellular structure having two opposing ends. The structure includes a plurality of intermediate walls arranged to provide a plurality of substantially parallel passages. The intermediate walls and passages extend longitudinally from the housing inlet to the housing outlet. The exhaust processor further includes plugs for closing alternate passages at opposite ends of the particulate trap. Additionally, the exhaust processor includes a seal on the peripheral edge at each end of the outer wall of the particulate trap to block the passage of combustion product through the passages adjacent to the outer wall. Each seal can include a side wall portion embracing the outer wall of the cellular structure and a lip portion overlying a radially outer portion of one end of the cellular structure.
