Existen otras formas de NOx como el N2O4 (el d\u00edmero del NO2), que s\u00f3lo existe a temperaturas m\u00e1s bajas, y el N2O5, por ejemplo. <\/p>\n\n\n\n<p class=\"has-text-align-justify wp-block-paragraph\">Sin embargo, debido a temperaturas de combusti\u00f3n mucho m\u00e1s altas debido a la alta compresi\u00f3n de los cilindros y al turbo o sobrealimentaci\u00f3n, los motores di\u00e9sel producen emisiones de NOx mucho m\u00e1s altas que los motores de gasolina de encendido por chispa. <\/p>\n\n\n\n<p class=\"has-text-align-justify wp-block-paragraph\">La reciente disponibilidad de reducci\u00f3n catal\u00edtica selectiva (SCR) permite que un motor di\u00e9sel debidamente equipado emita valores similares de NOx en el tubo de escape en comparaci\u00f3n con un motor de gasolina t\u00edpico con un catalizador de 3 v\u00edas. <\/p>\n\n\n\n<p class=\"has-text-align-justify wp-block-paragraph\">Adem\u00e1s, el catalizador de oxidaci\u00f3n del di\u00e9sel aumenta significativamente la fracci\u00f3n de NO2 en \u201cNox\u201d al oxidar m\u00e1s de 50% de NO utilizando el exceso de ox\u00edgeno en los gases de escape del di\u00e9sel.<br \/>El impulso para desarrollar un sensor de Nox proviene de factores ambientales. Los gases NOx pueden causar diversos problemas como el smog y la lluvia \u00e1cida. <\/p>\n\n\n\n<p class=\"has-text-align-justify wp-block-paragraph\">Muchos gobiernos de todo el mundo han aprobado leyes para limitar sus emisiones (junto con otros gases de combusti\u00f3n como Sox (\u00f3xidos de azufre), CO (mon\u00f3xido de carbono) y CO2 (di\u00f3xido de carbono) e hidrocarburos). <\/p>\n\n\n\n<p class=\"has-text-align-justify wp-block-paragraph\">Las empresas se han dado cuenta de que una forma de minimizar las emisiones de NOx es detectarlas primero y luego emplear alg\u00fan tipo de circuito de retroalimentaci\u00f3n en el proceso de combusti\u00f3n, minimizando la producci\u00f3n de NOx mediante, por ejemplo, la optimizaci\u00f3n de la combusti\u00f3n o la regeneraci\u00f3n de trampas de NOx.<\/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.
