Bertrand Lemire, Tim Walde: Method for determining a NOx concentration. Siemens Aktiengesellschaft, Laurence A Greenberg, Werner H Stemer, Ralph E Locher, March 2, 2004: US06699383 (170 worldwide citation)

A thick-film measurement sensor includes two measurement cells and is used to measure the NOx concentration in the exhaust gas from an internal combustion engine. The 1/&lgr; value of the exhaust gas is determined from an oxygen ion pump current flowing in the first measurement cell, for example, by ...

Bertrand Lemire, Willibald Schurz: Method for testing the functional capability of a catalytic converter with an oxygen sensor. Siemens Aktiengesellschaft, Herbert L Lerner, Laurence A Greenberg, November 2, 1999: US05974787 (12 worldwide citation)

A method for testing the functional capability of a catalytic converter of an internal combustion engine uses an exhaust-gas probe having a measuring electrode for measuring the resistance of a metal oxide layer having low catalytic activity. The resistance of the metal oxide layer is dependent on t ...

Bertrand Lemire, Willibald Schuerz: Exhaust gas sensor and circuit configuration for the exhaust gas sensor. Siemens Aktiengesellschaft, Laurence A Greenberg, Herbert L Lerner, June 16, 1998: US05767386 (3 worldwide citation)

An exhaust gas sensor has first and second sensor elements. Exhaust gas surroundings of the first sensor element are catalytically activated, so that an oxygen partial pressure which is in equilibrium will always be measured by the first sensor element, regardless of the conversion capability of a c ...
