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

    Detta är en avhandling från Stockholm : KTH

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

    Sammanfattning : 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. LÄS MER

  2. 2. Respiratory effects of particulate matter air pollution studies on diesel exhaust, road tunnel, subway and wood smoke exposure in human subjects

    Detta är en avhandling från Umeå : Umeå universitet

    Författare :Maria Sehlstedt; Umeå universitet.; [2011]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Airway inflammation; antioxidant; bronchoscopy; detoxification; immunohistochemistry; particulate matter; MEDICINE Social medicine Public health medicine research areas Environmental medicine; MEDICIN Socialmedicin Folkhälsomedicinska forskningsområden Miljömedicin;

    Sammanfattning : Background: Ambient air pollution is associated with adverse health effects, but the sources and components, which cause these effects is still incompletely understood. The aim of this thesis was to investigate the pulmonary effects of a variety of common air pollutants, including diesel exhaust, biomass smoke, and road tunnel and subway station environments.

  3. 3. Particulate Flows in Aftertreatment Systems

    Detta är en avhandling från Umeå : Umeå universitet

    Författare :Henrik Ström; [2011]
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  4. 4. Late Cycle Soot Oxidation in Diesel Engines

    Detta är en avhandling från Lund University Faculty of Engineering Department of Energy Sciences Division of Combustion Engines P.O. Box 118, SE-221 00 LUND Sweden

    Författare :Yann Gallo; Lunds universitet.; Lund University.; [2016-11-08]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Soot oxidation; Laser extinction; Optical diagnostics; Diesel engines; Gas sampling; Particulate matter;

    Sammanfattning : Diesel engines are the most common engine technology used in transportation. Its widespread use comes from its inherent high efficiency and its relative low cost. It suffers from pollutant emission issues, however, that need detailed understanding of their origins to meet the strictest current and upcoming emission standards. LÄS MER

  5. 5. Oil-related Particle Emissions from Diesel Engines

    Detta är en avhandling från Stockholm : KTH

    Författare :Petter Johansson; KTH.; [2008]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Diesel engine; Particle emissions; Particulate matter; PM; Lubrication oil; Inter-ring pressure; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : In recent decades much effort has gone into reducing particle emissions in the exhaust gases of heavy-duty diesel engines. Engine development has now reached the stage where it is worth to put heavy focus on the contribution of lubricating oil to particulate emissions in order to further reduce these emissions. LÄS MER
