Abstract
An in-line exhaust system for a v-configured transverse-mounted internal combustion engine includes a first passage for a first exhaust gas stream and a second passage for a second exhaust gas stream having a catalyst system disposed therein. An hydrocarbon adsorber structure having an inlet and outlet end, a desorption temperature and comprising a first substantially unobstructed flow region, and a second more obstructed flow region abutting the first region, is provided and positioned so that both the first and second exhaust gas streams are able to flow therethrough. A fluidics diverter is provided and disposed in the second exhaust gas stream upstream, and proximate to the first region, of the adsorber for diverting the second exhaust gas stream away from the said first region. The system additionally includes a burn-off catalyst disposed downstream from the adsorber.
