| titleOfInvention |
Method and apparatus for the operation of a sensor for determination of exhaust gas components, in particular for a motor vehicle |
| abstract |
The invention relates to a method and a device for operating a sensor (7) which is provided in an exhaust system of an internal combustion engine (1) for determining the emissions contained in an exhaust gas flow, in particular of nitrogen oxides, ammonia, oxygen and / or soot, wherein the Exhaust gas flow during measurement phases on the sensor (7) acts. Between the measuring phases, the sensor (7) is at least largely kept free of the exhaust gas flow, the duration and / or the frequency of the measuring phases being adjustable as a function of operating parameters of the internal combustion engine (1) and / or the exhaust gas control system. A measurement space (6) surrounding the sensor (7) is acted upon immediately after a measurement phase with a purge gas under pressure, whereby the exhaust gas present in the measurement space is displaced from the measurement space into the exhaust gas flow. |
