  2. 1. 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

  4. 2. NOx reduction with dimethyl ether in lean exhaust

    Author : Sara U Erkfeldt; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NOx storage; Dimethyl ether; ether; hydrocarbon-SCR; lean NOx reduction; alcohol; Cu-ZSM-5; lean NOx trap; alkane; alternative fuel;

    Abstract : There is a growing concern worldwide about the increase in anthropogenic greenhouse gas emissions, particularly carbon dioxide (CO2) from the combustion of fossil fuels. Vehicles with internal combustion engines contribute significantly to these emissions, which has led to an increased demand for engines running on alternative (non-fossil) fuels. READ MORE

  5. 3. Water-in-diesel emulsion and microemulsion fuels -The effect of water on emission levels

    Author : Anna Lif; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Combustion; Diesel; Soot; NMR; Microemulsion; PM; Emulsion; Surfactant; NOx; Diffusometry; Alternative fuels; Emission;

    Abstract : Water-in-diesel emulsions are known as environmentally favourable alternatives to conventional diesel fuel. Introducing water into the combustion results in reduced emissions of the health hazardous components nitrogen oxide (NOx) and particulate matter (PM). The concept of using emulsions is advantageous as it is easy to replace regular diesel. READ MORE

  6. 4. CFD Modeling of an Alcohol-Diesel Direct-Injection Dual-Liquid-Fuel Engine using OpenFOAM

    Author : Andreas Nygren; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Renewable Fuels; Dual-Fuel Combustion; CFD; Spray Modeling;

    Abstract : Legislation for heavy duty combustion engines are becoming more stringent. To keep up with the legislation, new engine technology is required. Furthermore, renewable fuels can also be used together with new engine technology to further reduce emissions. READ MORE

  7. 5. 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
