  1. 1. Late Cycle Soot Oxidation in Diesel Engines

    University dissertation from Lund University Faculty of Engineering Department of Energy Sciences Division of Combustion Engines P.O. Box 118, SE-221 00 LUND Sweden

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

    Abstract : 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. READ MORE

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

    University dissertation from Lund University Faculty of Engineering Department of Energy Sciences Division of Combustion Engines P.O. Box 118, SE-221 00 LUND Sweden

    Abstract : Diesel engine developers are facing major challenges when meeting future demands on NOx and particulate emissions. The exhausts after treatment systems are rapidly improving and the technologies available in a few years will be capable of cutting emission levels close to the demanded levels. READ MORE

  5. 5. Experimental Investigations of Combustion Chamber Heat Transfer in a Light-Duty Diesel Engine

    University dissertation from Department of Energy Sciences, Lund University

    Author : Jessica Dahlström; Lund University.; Lunds universitet.; [2016-06-03]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; internal combustion engines; heat transfer; diesel engine; Diesel combustion; combustion chamber geometry; piston geometry; spray parameters;

    Abstract : This work concerned experimental studies of heat transfer in a light-duty diesel engine. Combustion is affected by several parameters, such as pressure, engine speed, mass of injected fuel and in-cylinder gas flow. These parameters are in turn affected by the combustion chamber geometry and fuel spray characteristics. READ MORE
