ABSTRACT:
The instant invention is directed at an in-line engine exhaust system comprised of the following: (1) a first close-coupled catalyzed structure located in the exhaust stream, the catalyzed structure having an inlet and an outlet end disposed in a housing, a lightoff temperature, and comprising a first substantially unobstructed flow region, and a second more obstructed flow region abutting the first region, the first region being disposed to provide a substantially unobstructed flow path for exhaust gases in the exhaust gas stream; and, (2) a flow diverter connected to a secondary air source and disposed in the housing for diverting the exhaust gases away from the first region. Furthermore, the exhaust system may be provided with a second catalyzed structure located in the exhaust gas stream downstream from the housing. Also disclosed herein is a method of treating a hydrocarbon-containing engine exhaust steam utilizing the aforementioned inventive exhaust system.
