The aim of nox sensor is to protect and not harm the environment and the nature by minimizing the emission of exhaust gases. The sensor system comprises a ceramic NOx sensor linked to a microprocessor. By communicating with the vehicle’s engine management, the system ensures optimal control of key engine parameters such as exhaust gas recirculation, fuel-air ratio and, for SCR systems, urea injection. The MCT sensor is employed in both cars and light and heavy-duty commercial vehicles in combination with SCR emissions control. It is also used to control the regeneration cycles of NOx storage catalysts, which feature not only in diesel vehicles but also in modern direct-injection gasoline engines.
