Very precise and real-time readings from the exhaust gas system are required for efficient exhaust-gas treatment. In diesel vehicles, the nitrogen oxide (NOx) sensor is used to provide the signals for evaluation of quantity of injected (urea solution) AdBlue® in systems for selective catalytic reduction (SCR) and NOx reduction. In petrol as well as in diesel applications the signals of a NOx sensor can be used to monitor the vehicle (on-board monitoring of emissions and on-board diagnostics).
