Title: DIESEL EXHAUST AFTERTREATMENT SYSTEM AND PROCESS
Abstract:
A diesel engine (12), exhaust gas (32), aftertreatment system and process (10). The exhaust gas is filtered by a ceramic, oxidation-catalyst, monolith filter (24) to remove particulates and soot, and the filtered exhaust gas oxidized (24) to oxidize the noncondensed hydrocarbons. Periodically, the filter is backpulsed with a compressed fluid (14), like compressed air, to remove accumulated particulates and soot from the filter.
