  1. 1. Combined Empirical and 1D Modeling Approach for Exhaust Aftertreatment System for Heavy Duty Diesel Engines

    H-uppsats, Chalmers tekniska högskola/Institutionen för tillämpad mekanik

    Författare :Frida Almqvist; [2017]
    Nyckelord :Diesel oxidation catalyst; Diesel particulate filter; Kinetic modeling; Transport resistance;

    Sammanfattning : The aim of this project was to develop a model for the first part of the exhaust aftertreatmentsystem including diesel oxidation catalyst (DOC) and diesel particulate filter (DPF). The modelwould then be tested against test cell data to evaluate if it could be used in a virtual test rig. LÄS MER

  2. 2. A Method for Reducing Ash Volume in Wall-Flow Diesel Particulate Filters : Water Injection as a Service Tool to Improve Fuel Consumption and Particulate Filter Service Life

    Master-uppsats, Linköpings universitet/Maskinkonstruktion

    Författare :John Allen; [2017]
    Nyckelord :;

    Sammanfattning : .... LÄS MER

  3. 3. 1D Modeling and Simulations of Soot Oxidation in Diesel Particulate Filters and Monoliths using GT-POWER

    H-uppsats, Chalmers tekniska högskola/Institutionen för tillämpad mekanik

    Författare :Chanin Lerdmaleewong; Staffan Luong; [2016]
    Nyckelord :GT-POWER; Diesel Particulate Filter; Soot Oxidation; Detailed Kinetics Modeling; 1-D Simulation; Pressure Drop Model;

    Sammanfattning : Diesel particulate filter (DPF) is part of the exhaust aftertreatment system for diesel engines.The DPF’s main function is to trap particulate matter (soot) from the exhaust stream.The trapped soot is removed by regeneration of the filter. The regeneration process involvessoot oxidation via oxygen and nitrogen dioxide. LÄS MER

  4. 4. Thermal control of a lab-scale in-situ reator for soot oxidation

    H-uppsats, Chalmers tekniska högskola/Institutionen för tillämpad mekanik

    Författare :Annika Biro; Rebecka Eriksson; [2016]
    Nyckelord :Thermal fronts; Particulate Matter; Soot oxidation; DPF; Open flow substrate; 2D CFD model;

    Sammanfattning : CFD simulations were coupled with lab-scale experiments to study steep temperatureincreases (thermal fronts) during thermal regeneration of a diesel particulatefilter (DPF) via soot oxidation. The study investigated the conditions under whichthese fronts appear. LÄS MER

  5. 5. 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
