Abstract
An after-treatment component for receiving an exhaust stream from an internal combustion engine comprises a vessel having a first end, a second end, and an intermediate section. The vessel defines an inlet port and an outlet port. The inlet port is in fluid communication with an inlet diffuser disposed within the vessel. The inlet diffuser is in fluid communication with the inlet port and with a diesel oxidation catalyst disposed within the vessel. The diesel oxidation catalyst is in fluid communication with the inlet diffuser and with a transfer duct. The transfer duct is in fluid communication with the diesel oxidation catalyst and with an intermediate diffuser disposed within the vessel. The intermediate diffuser is in fluid communication with the transfer duct and with a catalyzed filter disposed within the vessel. The catalyzed filter is in fluid communication with the intermediate diffuser and with the outlet port.
