  1. 11. 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. 12. Chemical analysis for mapping of soot reactivity

    Uppsats för yrkesexamina på grundnivå, KTH/Skolan för kemivetenskap (CHE)

    Författare :Henrik Pettersson; [2013]
    Nyckelord :diesel soot; reactivity; oxidation; rail pressure; EGR; TGA; SEM; EDS;

    Sammanfattning : In order to increase the efficiency of diesel particulate filter regeneration more knowledge about diesel soot and its reactivity is required. This thesis compares soot created during accelerated filter loading by lowered rail pressure, with soot from normal filter loading. LÄS MER

  4. 13. Accuracy of PSA's DPF soot load estimator calibrated by means of a DoE model

    Master-uppsats, KTH/Maskinkonstruktion (Inst.)

    Författare :THOMAS LE BIHAN; [2013]
    Nyckelord :;

    Sammanfattning : The combustion process happening in the Diesel engine is naturally producing soot. These soot emissions have been known for being harmful for both our environment and especially our health. Aware of this situation, the governments worldwide have defined emission limits for our vehicles. LÄS MER

  5. 14. A Method for Estimating Soot Load in a DPF using an RF-based Sensor

    Master-uppsats, Institutionen för systemteknik; Tekniska högskolan

    Författare :Victor Ingeström; John Hansson; [2012]
    Nyckelord :Soot Sensor; Diesel Particulate Filter; Black Box; Average Gain;

    Sammanfattning : The European emission standard is an EU directive which describes what emission limits car manufactures are required to meet. In order to meet these requirements car manufacturers use different techniques and components. In a modern diesel automobile a Diesel Particulate Filter (DPF) is used to gather soot from the exhausts. LÄS MER

  7. 15. Modellbaserad temperaturregleringav partikelfiltrets regenereringsprocess

    Uppsats för yrkesexamina på avancerad nivå, Institutionen för informationsteknologi

    Författare :Thomas Forsberg; Martin Woxlin; [2011]
    Nyckelord :partikelfilter; katalysator; reglerteknik; IMC; framkoppling; euro-6; scania; flödesvarierande parametrar;

    Sammanfattning : Due to increasing regulations regarding new diesel vehicles particulate matteremissions the new Scania truck, Scania Euro 6, has been equipped with a particulatefilter. This component effectively stores the particles in the exhaust gas but must becleaned in order to prevent itself from clogging. LÄS MER
