ABSTRACT:
An oxygen partial pressure measuring device for determining oxygen partial pressures in exhaust gases emitted from internal combustion engines comprises a metallic vessel mounted within an exhaust pipe of the engine and having an exhaust gas inlet facing to the exhaust gas flow and an exhaust gas outlet formed in a side surface of the vessel, an oxygen concentration cell shutting the exhaust gas out of the air in an air-tight manner, and a monolithic structure, what is called a honeycomb structure, located between the exhaust gas inlet and the oxygen concentration cell within the vessel for burning the exhaust gas.
