Deutsche Vergaser Gmbh & Co Kommanditgesellschaft

Gunter Hartel

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.

Control installation for the proportioning of a secondary air quantity

Method and installation for the predetermined addition of secondary air used in effecting optimum combustion of internal combustion engine exhaust gases, including a control arrangement including one or more measuring devices sensing engine operating or exhaust gas contents and, in response to the sensed conditions, regulating the addition of secondary air in order to obtain optimum exhaust gas combustion.
