  2. 11. The Pneumatic Hybrid Vehicle - A New Concept for Fuel Consumption Reduction

    Author : Sasa Trajkovic; Förbränningsmotorer; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VVA; Regenerative; Air-motor; Compressor; Pneumatic; Hybrid; Vehicle; Electric Hybrid; Drive Cycle; GT-Power; Simulink; FPGA;

    Abstract : Urban traffic involves frequent acceleration and deceleration. During deceleration, the energy previously used to accelerate the vehicle is mainly wasted on heat generated by the friction brakes. If this energy that is wasted in traditional internal combustion engines (ICE) could be saved, the fuel economy would improve. READ MORE

    Author : Clement Chartier; Förbränningsmotorer; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Diesel; Combustion; Soot; UHC; Injections; Lift-off length; air-entrainement;

    Abstract : Internal combustion engines have been an important technological field for more than a century. It has had an important impact on society through improved transportation and industrial applications. READ MORE

  5. 13. Diffusive Combustion of Ethanol in a Dual-Fuel Direct Injection Compression Ignition Engine

    Author : Nicola Giramondi; Anders Christiansen Erlandsson; Mihai Mihaescu; Anders Jäger; Jan Erik Eismark; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Machine Design; Maskinkonstruktion;

    Abstract : The impact of climate change due to global warming necessitates rapid and extensive measures to enhance the sustainability of the energy and transport sectors. In this context, there are large environmental and societal benefits to be gained by replacing diesel with renewable fuels for road freight transport. READ MORE

  6. 14. Laser Diagnostics of HCCI and Partially Premixed Combustion

    Author : Leif Hildingsson; Förbränningsmotorer; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; low temperature combustion; Motorer; Motors and propulsion systems; Teknik; Technological sciences; PIV; in-cylinder flow structures; hydroxyl; OH; partially-oxidized fuel; formaldehyde; HCOH; LIF; diesel combustion; partially premixed combustion; PPC; HCCI; framdrivningssystem;

    Abstract : The work presented in this thesis deals with measuring in-cylinder combustion species and events using different laser-based diagnostic methods. A variety of engine operating modes, like HCCI and partially premixed diesel combustion, have been investigated. READ MORE

  7. 15. Investigation of a prototype industrial gas turbine combustor using alternative gaseous fuels

    Author : Ivan Sigfrid; Kraftverksteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Combustion; Gas Turbine; Laminar flame speed; Stretch; Lean blowout; Emissions;

    Abstract : In this thesis, the effect of alternative gaseous fuels, with high hydrogen content and lower calorific value, on gas turbine combustion was investigated experimentally. The aim of the investigation was to find operational limitations for an experimental burner and to supply data for validation of computational fluid dynamics (CFD). READ MORE
