  2. 21. Investigation of Partially Premixed Combustion in an Optical Engine : In-Cylinder Flow and Combustion Characterization

    Author : Slavey Tanov; Förbränningsmotorer; []
    Keywords : PPC; in-cylinder flow structures; Combustion diagnostics; Gasoline; Gasoline-Ethanol; Multiple Injection; Stratification Level;

    Abstract : The diesel engine is one of the most economic power sources and is therefore used in a range of technical solutions. The low fuel consumption combined with high engine performance makes it attractive for transportation vehicles. READ MORE

  4. 22. In-Nozzle Flow, Spray and Combustion Investigations of Two-Stroke Marine Diesel Engine Fuel Injectors

    Author : Reto Balz; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; spray morphology; marine Diesel engine; fuel injection; in-nozzle flow; combustion; cavitation;

    Abstract : This thesis focuses on the experimental studies of the cavitating in-nozzle flow of large two-stroke marine Diesel engine fuel injector nozzles and how it affects the spray morphology and combustion behaviour.  To further increase the efficiency of large two-stroke marine Diesel engines, a better understanding of the fuel spray atomization process is necessary.

  5. 23. Optical and laser diagnostics : The versatility of Imaging

    Author : Alexios Matamis; Förbränningsfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; methanol; COMBUSTION; diesel; schlieren; spray; imaging; pilot-injection; high-speed imaging; Fysicumarkivet A:2021:Matamis;

    Abstract : Optical and laser diagnostics is a field where optical techniques are developed that offer remote, non-intrusive measurements in order to characterise a system. Imaging is a big part of this field and the versatility it offers makes it a great tool in the hands of researchers and in practical applications. READ MORE

  6. 24. Optical diagnostics of Soot in optically dense sprays

    Author : Raul Lima Ochoterena; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Soot diagnostics in engines can be carried out with optical methods that have the potentialfor high temporal and spatial resolution. Some of these methods were appliedto study diesel spray combustion in the Chalmers High Pressure, High Temperature(HP/HT) spray rig. READ MORE

  7. 25. THE EFFECTS OF VARIOUS NOZZLE HOLE CONFIGURATIONS ON DIESEL ENGINE PERFORMANCE

    Author : Andreas Matsson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Diesel engine combustion non-circular nozzle hole cavitation hydrogrinding optical study flame wall interaction;

    Abstract : Any improvement that can be done with the diesel engine to reduce emissions and fuel consumption is of importance. The aim of the studies presented in this thesis was to determine whether changes in the nozzle geometry of the fuel injection systems used in diesel engines might improve their emissions and fuel consumption.
