  5. 4. Late Cycle Soot Oxidation in Diesel Engines

    Författare :Yann Gallo; Förbränningsmotorer; []
    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

  7. 5. Processes in Optical Diesel Engines - Emissions Formation and Heat Release

    Författare :Ulf Aronsson; Förbränningsmotorer; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Diesel Engines; Optical Engines; Heat Release; Combustion; Emissions Formation; Mechanical Deformation;

    Sammanfattning : This project deals with questions related to generic diesel combustion research and optically accessible engines are used to study the combustion process. Images of the combustion are analyzed together with in-cylinder pressure and exhaust gas emission measurements. LÄS MER
