    Sammanfattning : Today, one third of Sweden’s total greenhouse gas emissions come from domestic transport. To reduce these emissions, the Swedish government has set emission targets. To meet these and to avoid the global impacts of climate changes, the need for new technologies and new fuels to replace fossil fuels has become evident. LÄS MER

  4. 13. Electrification Of A Tiltrotator : Electrifying The Hydraulic Tilt Function

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Sammanfattning : As new emission regulations in the EU set more stringent requirements on greenhouse gas (GHG) emissions, original equipment manufacturers (OEM) must find ways to align with the EUs sustainability goals. By transitioning to more electrically driven machinery, operators of off-highway vehicles can benefit from better fuel economy, lower greenhouse gas emissions and less air pollution. LÄS MER

  5. 14. 3D CFD Simulations of Hydrogen Engine Combustion

    Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

    Författare :Hao Liu; [2023]
    Nyckelord :Technology and Engineering;

    Sammanfattning : With the trend of decarbonization, the transport sector is exploring possibilities of fossil fuel free solutions. Hydrogen can be a potential fuel for future engine applications. In this work, the concept of H2 HPDI is investigated, where a pilot diesel injection ignites the hydrogen jet. LÄS MER

  7. 15. Climbing to new heights : The importance of considering passengers on the flight towards more sustainable forms of aviation

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)
