    Abstract : Several aspects make today’s transport system non-sustainable: • Production, transport and combustion of fossil fuels lead to global and local environmental problems. • Oil dependency in the transport sector may lead to economical and political instability. READ MORE

  4. 7. Chemical-Looping Combustion with Liquid Fuel

    Author : Patrick Moldenhauer; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Chemical-looping combustion (CLC) is a promising technology for future energy conversion on the basis of combustion of fossil fuels with inherent CO2 separation. In comparison to other carbon-capture technologies there is no need for energy demanding gas separation in order to obtain pure CO2. READ MORE

  5. 8. A Surface Engineering Approach to Reduction of Frictional Losses of Heavy Duty Diesel Engines

    Author : Staffan Johansson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cylinder Liner; Tribometer; Wear; Diesel Engine; Lubrication; Design of Experiments; Rig testing; Friction; Piston Ring; Oil consumption;

    Abstract : Reducing emissions is a top priority within heavy duty diesel engine development and research. The aim of the work is to decrease the fuel consumption by decreasing frictional losses of the Power Cylinder Unit.Full scale testing of engine components improvements is time-consuming and costly.

  6. 9. Simulation of twin land oil control ring in heavy duty diesel engines

    Author : Markus Söderfjäll; Peder Klit; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Maskinelement; Machine Elements;

    Abstract : With today’s striving towards reduction of fuel consumption it is moreimportant than ever to understand how different components in theinternal combustion engine function. There is a need for tools that canbe used to investigate and predict the result of specific design changesmade on the components. READ MORE

  7. 10. Towards sustainable heavy-duty transportation : Combustion and emissions using renewable fuels in a compression ignition engine

    Author : Maja Novakovic; Förbränningsmotorer; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; RME; HVO; E85; methanol; ethanol; decarbonization; defossilization; heavy-duty; compression-ignition engine; ow temperature combustion; PPC; emissions; PM; particles; aerosol; OA; SOA; DOC;

    Abstract : Transportation should become sustainable and available to everyone. Currently, transportation accounts for approx. one sixth of greenhouse gas (GHG) emissions globally, and heavy-duty trucks are responsible for almost 30% of that. READ MORE
