NOx sensors represent state of the art technology that is applied to gasoline lean burn engines, as part of an engine control and diagnostic system, used to insure proper operation of the NOx emission control system. These sensors can be incorporated, independent of the NOx emission control technology used on the vehicle, and their function is primarily to monitor the NOx conversion efficiency and regeneration of the catalyst material. The sensors can work as part of a feedback to the ECM, and to make real time adjustments to the NOx regeneration using a momentary 3 to 10 seconds rich mixture. The principle of operation of the NOx sensor is based on proven solid state technology developed for oxygen or wide-band sensors. The dual chamber zirconium sensing element and electro-chemical pumps, work in conjunction with precious metals electrodes, to control the oxygen concentration within the sensor chambers and then convert the NOx to nitrogen. The sensor sends an output voltage signal that is directly proportional to the NOx concentration. The NOx sensor can be incorporated upstream and downstream of the catalyst, to provide a feedback control loop to the ECM, indicative of the ... Get the whole story right here in this video...
