Abstract
A modular catalytic converter and muffler is used to purify exhaust from a relatively large diesel engine. The device includes various structural components that are mounted in the exhaust flow path within a housing having an inlet and an outlet. A plate mounted within the housing divides the housing into an inlet chamber and an outlet chamber. A plurality of catalytic converter sub-cans are mounted across the plate between the inlet chamber and the outlet chamber. A flow distributor is mounted within the housing upstream of the catalytic converter sub-cans. The flow distributor divides and directs a portion of the exhaust to each of the catalytic converter sub-cans. Some muffler structure is mounted within the housing between the catalytic converter sub-cans and the outlet in order to attenuate noise in the exhaust.
