Adem\u00e1s, se han desarrollado sensores de NH3 para su uso en sistemas SCR. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">El desarrollo de estos sensores comenz\u00f3 en la d\u00e9cada de 1990 y las versiones comerciales se introdujeron por primera vez a principios de la d\u00e9cada de 2000 para su uso en autom\u00f3viles de pasajeros de gasolina de mezcla pobre y veh\u00edculos di\u00e9sel con adsorbentes de NOx y postratamiento de urea-SCR para motores di\u00e9sel de servicio ligero y pesado.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">El sensor de NOx mide la cantidad de \u00f3xidos de nitr\u00f3geno (NOx) presentes en los gases de escape de un motor de combusti\u00f3n interna. Estos sensores utilizan una celda electroqu\u00edmica para detectar la concentraci\u00f3n de NOx en la corriente de escape y proporcionar retroalimentaci\u00f3n en tiempo real al sistema de control del motor, que luego puede ajustar la mezcla de aire y combustible o el funcionamiento del sistema de postratamiento de NOx para reducir las emisiones. La funci\u00f3n del sensor es crucial para garantizar que el motor cumpla con los est\u00e1ndares de emisiones y funcione de manera eficiente.<\/p>\n\n<div class=\"text-center mt-12 py-10 bg-gradient-to-r from-blue-600 to-blue-800 rounded-xl text-white\">\n<h3 class=\"text-2xl font-bold mb-3\">Browse Our NOx Sensors<\/h3>\n<p class=\"text-blue-100 mb-6 max-w-xl mx-auto\">Find the right NOx sensor for your vehicle.
