    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. 2. Fischer-Tropsch and FAME Fuels as Alternatives for Diesel Engines; an Experimental Study

    Author : Monica Johansson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Emissions; SME; Fischer-Tropsch; NOx; Combustion; Alternative fuels; Soot; Biodiesel; RME; FAME; GTL; PME;

    Abstract : Research into alternative fuels is necessitated by our heavy reliance on limited oil reserves and increasingly strict emissions legislation. The studies reported in this thesis involved conducting engine tests using alternatives to fossil Diesel fuel in both heavy-duty and light-duty single cylinder engines. READ MORE

  5. 3. Experimental evaluation of renewable drop-in fuel blends for compression ignition engines

    Author : Josefine Preuss; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Compression Ignition Engine; Renewable fuels; Particle emissions; long-chain alcohol blends;

    Abstract : Driven by the need to reduce greenhouse gas emissions while meeting the growing demand for mobility, the transport sector is shifting towards more sustainable and less polluting energy sources. Although vehicle electrification is advancing, it will take decades for electric vehicles to completely replace all current vehicles powered by internal combustion engines. READ MORE

  6. 4. Methanol Diesel Dual Fuel Direct Injection in a HD-CI Engine

    Author : Michael Saccullo; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Alcohol Fuels; Heavy Duty Engine; Dual Fuel; Combustion;

    Abstract : Laws concerning emissions from heavy duty (HD) internal combustion engines are becoming increasingly stringent. New engine technologies are needed to satisfy these new requirements and to reduce fossil fuel dependency. READ MORE

  7. 5. Energy systems studied of biogas : Generation aspects of renewable vehicle fuels in the transport system

    Author : Mimmi Magnusson; Per Alvfors; Umberto Desideri; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Anaerobic digestion; biogas; biomass; energy system; first-generation biofuels; renewable vehicle fuels; second-generation biofuels; supply- and demand-side measures; third-generation biofuels; transport system;

    Abstract : The transport sector is seen as particularly problematic when concerns about climate change and dependency on fossil energy are discussed. Because of this, bioenergy is strongly promoted for use in the transport sector, both on a European level and nationally in Sweden. READ MORE
