Abstract:
A control device for a cleaning installation which is interconnected in the exhaust gas system of an internal combustion engine and absorbs the harmful substances of the exhaust gases; the control device thereby controls the through-flow of the exhaust gases through the cleaning installation as a function of the operating condition of the internal combustion engine and utilizes for this control a flow-controlled exhaust gas conduit system; the flow-controlled exhaust gas conduit system is arranged between an exhaust gas manifold and a catalyst serving as cleaning installation and is itself controlled automatically by the flow resistance of the catalyst and by exhaust gas channels of different cross sections and/or configurations interconnected in the exhaust gas conduit system.
