  1. 1. Particulate Emissions Associated with Diesel Engine Oil Consumption

    University dissertation from Stockholm : KTH

    Author : Petter Tornehed; KTH.; [2010]
    Keywords : Lubrication oil; Particulate emission; Particulate matter PM ; Oil consumption; Diesel engine; TECHNOLOGY Other technology Mechanical engineering; TEKNIKVETENSKAP Övriga teknikvetenskaper Maskinteknik;

    Abstract : Particulate emissions from diesel engines have been a key issue for diesel engine developers in recent decades. Their work has succeeded in reducing the exhaust particles from the combustion of fuel, which has led to increasing interest in the contribution of particulates from lubrication oil. READ MORE

  2. 2. Multiscale methods for the fundamental understanding of diesel soot mitigation

    University dissertation from Stockholm : KTH

    Author : Carl Justin Kamp; [2011]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Nanofabrication; Catalyst; Soot; Aftertreatment; Carbon; Particulate Matter; Oxidation; Ash; Diesel Particulate Filter;

    Abstract : Current regulations for diesel exhaust emissions cannot be met by engine improvements alone, and for this reason the diesel particulate filter (DPF) is a widely used aftertreatment component for the control of diesel particulate matter (PM). The DPF functions by trapping PM and destroying it by oxidation. READ MORE

  3. 3. Particulate Flows in Aftertreatment Systems

    University dissertation from Stockholm : KTH

    Author : Henrik Ström; [2011]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Modeling; Computational fluid dynamics; Exhaust gas aftertreatment; Particulate matter; Multiphase flow; Particulate flow;

    Abstract : Emissions from internal combustion engines contain many components that have a detrimental effect on the environment and on human health, such as nitrogen oxides (NOx) and particulate matter (PM). In addition, the final product of any combustion of fossil fuel - carbon dioxide (CO2) - contributes to global warming. READ MORE

  4. 4. Diesel exhaust and wood smoke mechanisms, inflammation and intervention

    University dissertation from Umeå : Umeå Universitet

    Author : Ala Muala; Umeå universitet.; [2014]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Air pollution; deposition; bronchoscopy; Immunohistochemstry; filter; NO bioavailability; lungmedicin; Lung Medicine;

    Abstract : Background Particulate matter (PM) air pollution is associated with increased respiratory and cardiovascular morbidity and mortality. Diesel engine exhaust (DE) and wood combustion are major contributors to ambient air pollution and adverse health effects. READ MORE

  5. 5. Eulerian-Lagrangian modeling of particle motion in exhaust gas aftertreatment systems

    University dissertation from Umeå : Umeå Universitet

    Author : Henrik Ström; [2009]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; urea-SCR; particle trapping; flow-through filter; urea decomposition; diesel particulate matter; particle motion; particle filter; AdBlue-spray; Eulerian-Lagrangian modeling;

    Abstract : In the work to design and optimize new aftertreatment system devices for NOx reduction and particulate matter removal in lean engine exhaust (such as diesel exhaust), it is of great help to be able to perform quick, robust and reliable computer simulations of system performance. A suitable platform for such simulations is Computational Fluid Dynamics (CFD) software. READ MORE
