Patent ID: 11098633

Abstract:
The invention relates to an exhaust gas aftertreatment system for an internal combustion engine comprising a first catalytic converter that has a first exhaust gas inlet to admit the exhaust gas into the first catalytic converter and has an exhaust gas outlet positioned on the opposite side, also comprising a second catalytic converter that is arranged downstream from the first catalytic converter and that is flow-connected to the first catalytic converter in order to allow the exhaust gas to pass from the first catalytic converter into the second catalytic converter and that likewise has a second exhaust gas inlet that is at a physical distance from the exhaust gas outlet of the first catalytic converter. The exhaust gas aftertreatment system also comprises a particulate filter that is arranged downstream from the second catalytic converter and that is flow-connected to the second catalytic converter in order to allow the exhaust gas to pass from the second catalytic converter into the particulate filter. A flow-around area is formed adjacent to an outer surface of the first catalytic converter in which the exhaust gas flows from the exhaust gas outlet to the second exhaust gas inlet into the second catalytic converter.
