  1. 6. Modellering av åldring av dieseloxidationskatalysatorer

    Master-uppsats, KTH/Skolan för kemivetenskap (CHE)

    Författare :Filip Gruvnäs; [2015]
    Nyckelord :Diesel oxidation catalyst; Aging; NO oxidation; Equivalent thermal load; Sulfur;

    Sammanfattning : A conventional exhaust gas after treatment system (EATS) for the Euro VI legislation contains four different catalyst. The first two (particulate filter system) remove particulates and the last two (SCR system) remove nitrogen oxides (NOx). LÄS MER

  3. 7. Fuel quality sensors for HD engines

    Master-uppsats, KTH/Maskinkonstruktion (Inst.)

    Författare :Cosmin Duca; [2014]
    Nyckelord :;

    Sammanfattning : Under de senaste åren har de globala utsläpps standarder blivit mer stringenta när vi talar om Heavy Duty (HD) Dieselmotorer. Dessutom har varje region, eller land, sina egna regler med egna utsläppsnivåer för de huvudsakliga föroreningarna: CO, kolväten (HC), kväveoxider och partiklar (PM). LÄS MER

  4. 8. Workshop Methods for Troubleshooting the Performance of the After-treatment system

    Master-uppsats, KTH/Maskinkonstruktion (Inst.)

    Författare :André Åkerberg; Daniel Törnroos; [2013]
    Nyckelord :;

    Sammanfattning : New legislations are constantly arising in Europe that puts stringent restrictions on the emissions coming from heavy-duty vehicles. The latest one is the Euro VI that has tough limits on both nitrogen oxides (NOx) and particulate matter (PM). LÄS MER

  5. 9. Concept study - lower exhaust gas temperature in Scania buses

    Master-uppsats, KTH/Maskinkonstruktion (Inst.)

    Författare :Birk Jansson; Mikael Jarsäter; [2013]
    Nyckelord :Exhaust gas temperature reduction; diffuser; bus; EuroVI; venturi; CFD; Avgastemperaturssänkning; buss; diffusor; EuroVI; CFD;

    Sammanfattning : The thesis aims to lower the exhaust gas temperature on the coming EU6 Scania buses D7 and Otto gas and is carried out as a final part of the studies in the mechanical engineering program, KTH Stockholm. Euro 6, a new emission standard requirements for heavy duty trucks and buses, puts new demands on the amount of particulate matter and nitrogen oxides that can be emitted. LÄS MER

  7. 10. VVA-strategier för avgastemperaturhöjning på en HD-Dieselmotor

    Master-uppsats, KTH/Maskinkonstruktion (Inst.)

    Författare :Anders Wickström; [2012]
    Nyckelord :;

    Sammanfattning : Regulations on the exhaust emissions of HD-diesel engines are becoming more and more stringent, and therefore, emission after-treatment systems are commonly used. These systems rely on catalytic conversion of NOx,CO , and HC emissions, and are thus dependant on temperature. LÄS MER
