ABSTRACT:
A control installation for the proportioning of a secondary air quantity employed for achieving optimum combustion or after-burning in internal combustion engines. The installation provides for stabilization of the measuring receptivity of sensors employed for the measurement of the oxygen content or carbon monoxide content of the exhaust gases, and to reduce the load on a subsequently switched-in after-burner. Upstream of the sensor employed for the measurement of the oxygen content or carbon monoxide content of the exhaust gases, there is located a catalytically operative element for effecting the conversion of the deleterious materials into other harmless materials or compounds. The catalytically operative element may be combined in a unitary structure with a mixing chamber.
