Dar\u00fcber hinaus wurden NH3-Sensoren f\u00fcr den Einsatz in SCR-Systemen entwickelt. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Die Entwicklung dieser Sensoren begann in den 1990er Jahren und kommerzielle Versionen wurden erstmals in den fr\u00fchen 2000er Jahren f\u00fcr den Einsatz in Personenkraftwagen und Dieselfahrzeugen mit Magerverbrennungsmotor mit NOx-Adsorbern und Harnstoff-SCR-Nachbehandlung f\u00fcr leichte und schwere Dieselmotoren eingef\u00fchrt.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Der NOx-Sensor misst die Menge an Stickoxiden (NOx), die im Abgas eines Verbrennungsmotors vorhanden sind. Diese Sensoren nutzen eine elektrochemische Zelle, um die NOx-Konzentration im Abgasstrom zu erfassen und liefern Echtzeit-Feedback an das Motorsteuerungssystem, das dann das Luft-Kraftstoff-Gemisch oder den Betrieb des NOx-Nachbehandlungssystems anpassen kann, um die Emissionen zu reduzieren. Die Funktion des Sensors ist entscheidend daf\u00fcr, dass der Motor die Emissionsnormen einh\u00e4lt und effizient arbeitet.<\/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.
