  1. 1. Characterization of NOx sensor performance under oscillating pressure conditions

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Álvaro López Méndez; [2023]
    Keywords : NOx sensors; engine – out heavy duty vehicle conditions; oscillating pressure; test rig testing; NOx-sensorer; motor – ut tunga fordonsförhållanden; oscillerande tryck; testriggtestning;

    Abstract : The NOx sensor is essential in the modern after-treatment system. Due to the introduction of regulations from the US, it is necessary to investigate how these sensors operate in conditions of pulsating pressures generated engine - out, after the turbocharger. READ MORE

  3. 2. Behaviour of NOx sensors at their end of life

    University essay from KTH/Förbränningsmotorteknik

    Author : Jose Mathew; [2020]
    Keywords : NOx sensor; failure modes; oscillatory fault monitor; diagnosis of sensors; NOx sensor; felfunktioner; oscillerande felmätare; diagnos av sensorer;

    Abstract : NOx-sensorn är grundläggande i det moderna efterbehandlingssystemet och dess pålitlighet är avgörande för att kunna leva upp till rådande emissionslagkrav. Livslängden samt sensorns beteende i slutet av denna varierar betydligt. READ MORE

  4. 3. Water blow out phenomena inside a heavy truck silencer

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Rohit Suram Venkata Subramaniyam; [2020]
    Keywords : Water blow out in after treatment devices; Dew point strategy; Exhaust after treatment system; NOx sensors; Water formation in the exhaust; Vatten blåser in efter behandlingsanordningar; Daggpunktsstrategi; Avgas efter behandlingssystem; NOx-sensorer; Vattenbildning i avgaserna;

    Abstract : NOx sensors have become salient components in the development of efficient exhaust after treatment system for heavy duty vehicles in the past few years. When the accumulated water inside the silencer splashes on to the NOx sensor, it can cause permanent cracks in the sensor. READ MORE
