Es gibt andere Formen von NOx, wie zum Beispiel N2O4 (das Dimer von NO2), das nur bei niedrigeren Temperaturen existiert, und N2O5. <\/p>\n\n\n\n<p class=\"has-text-align-justify wp-block-paragraph\">Aufgrund der viel h\u00f6heren Verbrennungstemperaturen aufgrund der hohen Zylinderkompression und der Turbo- oder Aufladung erzeugen Dieselmotoren jedoch viel h\u00f6here NOx-Emissionen als Ottomotoren mit Fremdz\u00fcndung. <\/p>\n\n\n\n<p class=\"has-text-align-justify wp-block-paragraph\">Die j\u00fcngste Verf\u00fcgbarkeit der selektiven katalytischen Reduktion (SCR) erm\u00f6glicht es einem ordnungsgem\u00e4\u00df ausgestatteten Dieselmotor, \u00e4hnliche NOx-Werte am Auspuff auszusto\u00dfen wie ein typischer Benzinmotor mit einem 3-Wege-Katalysator. <\/p>\n\n\n\n<p class=\"has-text-align-justify wp-block-paragraph\">Dar\u00fcber hinaus erh\u00f6ht der Dieseloxidationskatalysator den NO2-Anteil in \u201eNox\u201c erheblich, indem er \u00fcber 501 TP3T NO unter Verwendung des \u00fcbersch\u00fcssigen Sauerstoffs in den Dieselabgasen oxidiert.<br \/>Der Antrieb zur Entwicklung eines Nox-Sensors ergibt sich aus Umweltfaktoren. NOx-Gase k\u00f6nnen verschiedene Probleme wie Smog und sauren Regen verursachen. <\/p>\n\n\n\n<p class=\"has-text-align-justify wp-block-paragraph\">Viele Regierungen auf der ganzen Welt haben Gesetze zur Begrenzung ihrer Emissionen erlassen (zusammen mit anderen Verbrennungsgasen wie Sox (Schwefeloxide), CO (Kohlenmonoxid) und CO2 (Kohlendioxid) sowie Kohlenwasserstoffe). <\/p>\n\n\n\n<p class=\"has-text-align-justify wp-block-paragraph\">Unternehmen haben erkannt, dass eine M\u00f6glichkeit zur Minimierung von NOx-Emissionen darin besteht, sie zun\u00e4chst zu erkennen und dann eine Art R\u00fcckkopplungsschleife im Verbrennungsprozess einzusetzen, um die NOx-Produktion beispielsweise durch Verbrennungsoptimierung oder Regeneration von NOx-Fallen zu minimieren.<\/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.
