  1. 1. Reducing Diesel Engine Emissions - An Experimental Investigation

    Författare :Arjan Helmantel; [2004]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Optical methods; Soot; Diesel; Emissions; HCCI;

    Sammanfattning : In the recent past, the Diesel engine has been improved considerably in the areas ofperformance, fuel efficiency and exhaust emissions. In Europe, these improvements haveresulted in a strong increase in the sales of passenger cars equipped with a Diesel engine. LÄS MER

  2. 2. On soot oxidation in heavy duty diesel engine combustion

    Författare :Jan Eismark; [2012]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Diesel engine; oxidants; soot oxidation; soot formation; emissions; combustion; turbulence;

    Sammanfattning : Soot emissions from diesel engine combustion are harmful both for the health and the environment. Soot is also a limiting factor in the work to lower the emissions of nitrogen emissions (NOx) and to improve the fuel consumption. In the present work, experimental and simulation methods were used to study soot processes during the combustion. LÄS MER

  3. 3. 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; [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. Water-in-diesel emulsion and microemulsion fuels: composition, structure and effect on emissions

    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 :Anna Lif; [2010]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NOx; microemulsion; combustion; diffusometry; alternative fuels; emission; emulsion; Fischer-Tropsch; MFC; PM; microfibrillated cellulose; NMR; surfactant; soot; diesel;

    Sammanfattning : Water-in-diesel fuels, as emulsions and microemulsions, give reduced emissions of nitrogen oxides (NOx) and particulate matter (PM) in combustion in diesel engines compared to regular diesel. These fuels can contribute to an improved local environment in densely populated areas as they can replace regular diesel in existing vehicles without any engine modification requirements. LÄS MER
