Abstract
An exhaust gas cleaning system for an internal combustion engine for a motor vehicle has a catalytic converter housing with an associated exhaust catalytic converter and an inlet opening for connecting an exhaust pipe. A throttle element is arranged in the catalytic converter housing, in such a manner that a first reaction chamber, which lies between the throttle element and the inlet opening, and a second reaction chamber, which lies between throttle element and exhaust catalytic converter, are formed by the throttle element.
