  • Exhaust gas system with HC adsorber and parallel catalytic converter, and vehicle comprising such an exhaust gas system
    Patent number: 9062580
    Abstract: The invention relates to an exhaust gas system (10) for an internal combustion engine (12), having an exhaust gas path which includes at least in sections two parallel exhaust gas lines (34, 36), namely a main line (34) and an auxiliary line (36), an adsorber (46) for reversible sorption of unburnt hydrocarbons (HC) and/or nitrogen oxides (NOx) being situated in the auxiliary line (36); having an adjusting means (48) for selectively guiding an exhaust gas flow into the main line (34) and/or into the auxiliary line (36) and having a main catalytic converter (44) situated downstream from the parallel exhaust gas lines (33, 36). An exhaust gas flow-conducting, gas-permeable element (58) is provided upstream from the adsorber (46), which separates the auxiliary line (36) from the remaining exhaust gas flow-conducting areas. In addition, the adsorber (46) may also be equipped with a particle filtering function and/or a catalytic function.
