  2. 11. Experimental Studies of Advanced Ignition Systems for Lean Burn Natural Gas Engines

    Author : Jessica Dahlström; Förbränningsmotorer; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ignition system; spark energy; internal combustion engine; engine; spark ignition; natural gas;

    Abstract : One of the greatest challenges for the transport sector today is reducing its environmental impact. This applies especially to the emission aspects, much due to increasingly stringent emissions legislations. READ MORE

  4. 12. Injection and Combustion of Alternative Fuels in Spark Ignited Direct Injection Engines

    Author : Lars Christian Riis Johansen; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; gas fuel; direct injection; E85; stratified combustion; spark ignition; alternative fuels; optical measurements;

    Abstract : Increasingly stringent vehicle emission legislation necessitates increasingly efficient combustion engines. The use of direct injection in spark ignited engines improves engine efficiency and reduces CO2 emissions. READ MORE

  5. 13. Efficient energy use in different applications

    Author : Lars Johansson; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energiteknik; Energy Engineering;

    Abstract : There is a steadily growing awareness for environmental issues caused by the increased energy use, mainly in the industrial world. The use of fossil fuels has reached the point where it can not be looked at as an endless source, the resources are decreasing at a pace where alternative energy sources will be a necessity for this and future generations.

  6. 14. 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

  7. 15. National Energy System Modelling of Industry : Optimising the Transition Towards Carbon Neutrality

    Author : Erik Sandberg; Anna Krook-Riekkola; Andrea Toffolo; Åsa Lindman; Peter Lund; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energiteknik; Energy Engineering;

    Abstract : Industry is a major user of energy and emitter of fossil CO2. At the same time, Sweden targets net-zero greenhouse gas emissions by 2045. Current policies to reduce greenhouse gas emissions and mitigate climate change, and the transition of the energy system it requires, will present major challenges for industry. READ MORE
