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

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

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

    Sammanfattning : 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. LÄS MER

  4. 3. Electrically Assisted Turbocharger: Modelling And Control Strategy

    Master-uppsats, Linköpings universitet/Fordonssystem

    Författare :Erik Vandor; Gabriel Ehlin; [2022]
    Nyckelord :EAT; VGT; VNT; Hybrid powertrain; electric turbocharger;

    Sammanfattning : A major cause of CO2 emissions today is fossil fuel vehicles, and lowering these emissions is of key importance, resulting in increasing electrification and hybridisation nowadays. Turbochargers have been used for a long time to recycle exhaust gas heat losses to improve engine performance by compressing the intake air. LÄS MER
