  1. 6. Alcohol Flexible Dual-Fuel Direct Injection Engine

    Författare :Michael Saccullo; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fuel spray; Ethanol; Dual-fuel; Heavy duty engine; Diffusion combustion; Dual-direct injection; E85; Methanol;

    Sammanfattning : Laws concerning emissions from HD internal combustion engines are becoming increasingly stringent in terms of local emissions and emissions concerning global warming such as lowering tailpipe CO2. New engine technologies are needed to satisfy these new requirements and to reduce fossil fuel dependency and increase renewable fuels in the transportation sector. LÄS MER

  3. 7. Modeling of Spray Formation and Development in OpenFOAM with Application to Diesel and Alcohol Fuels

    Författare :Andreas Nygren; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Combustion; Spray Formation; Spray Modeling; VSB2;

    Sammanfattning : Legislation with reagards to fuel emissions are becoming more stringent. This creates a need for improved engine concepts and fuels. This work is part of an ongoin project to create a concept for a direct injection dual fuel engine, which uses alcohol as main fuel and diesel as a pilot. LÄS MER

  4. 8. Combustion of selected alternative liquid fuels at oxy-fuel conditions: experiments and modelling

    Författare :Jenny D. Nauclér; Förbränningsfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Alcohols; Nitromethane; Chemistry; Laminar burning velocity; Ignition; Combustion; Fysicumarkivet A:2016:Nauclér;

    Sammanfattning : Combustion of fuels is a major source of energy and at the same time a threat to the environment. Carbon dioxide (CO2) emissions are one of the obstacles on the route to cleaner energy. Combining Carbon Capture and Storage-technology (CCS) with use of biofuels lead to a negative net release of CO2 can be achieved. LÄS MER

  5. 9. Experimental Study of Using Butanol or Octanol Blends as Alternative Fuels in Diesel Engines

    Författare :Tankai Zhang; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : With the increased travel demand, the consumption of fossil fuels, as the main energy source for transportation, has risen sharply over the last few decades. Fossil fuels are considered a non-renewable resource. In addition, burning them in internal combustion engines can generate a large amount of greenhouse gas (GHG) emissions. LÄS MER

  7. 10. Experimental Studies on Using Butanol and Octanol Isomers as Drop-in Fuels for Diesel Engines

    Författare :Tankai Zhang; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The increasing importance of transportation in modern societies has caused fossil fuel consumption to increase greatly in recent decades. However, burning fossil fuels in internal combustion engines can lead to high emissions of greenhouse gases, which cause climate change. LÄS MER
