  2. 21. Experimental Study of Using Butanol or Octanol Blends as Alternative Fuels in Diesel Engines

    Author : Tankai Zhang; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : 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. READ MORE

  4. 22. Deactivation of SCR catalysts - Impact of sulfur and the use of biofuels

    Author : Johanna Englund; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Cu-SSZ-13; Cu-CHA; Catalyst deactivation; Activity test; DeNOx; Sulfur; NOx reduction; NH3-SCR; FAME; Emission control; HVO; Vanadia; Biofuel;

    Abstract : In a near future, limits on CO2 emissions from vehicles will be introduced, which requires development of more fuel-efficient engines and most likely a transition towards the use of more biofuels. With the implementation of biofuels several issues could arise, one being the lack of fuel standards for these new type of fuels, leading to higher concentrations of catalyst poisons compared to conventional fossil fuels.

  5. 23. Bio-diesel Spray Combustion Modeling Based on a Detailed Chemistry Approach

    Author : Junfeng Yang; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; engine modeling; bio-diesel; thermo-physical properties; detailed chemistry combustion; emissions formation; spray characteristics;

    Abstract : The increased use of bio-diesel fuel is expected to reduce emissions of carbon-containing greenhouse gases. To optimize the application of bio-diesel in internal combustion engines, a theoretical model has been developed. READ MORE

  6. 24. Particle Emissions from District Heating Units Operating on Solid Biofuels

    Author : Aneta Wierzbicka; Ergonomi och aerosolteknologi; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; district heating; particle emissions; biomass combustion;

    Abstract : With the increasing interest in the use of biofuels for heat and energy generation there is a growing concern about emissions from their combustion. It has been shown that biofuel furnaces emit relatively high quantities of particulate matter in comparison to natural gas and light fuel oil furnaces. READ MORE

  7. 25. A simulation tool for optimising combustion engine cylinder liner surface texture

    Author : Andrew Spencer; Martin Priest; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Maskinelement; Machine Elements;

    Abstract : Fuel efficiency is one of the most important areas of automotive vehicle research and development today, with rising fuel costs, energy security and environmental concerns being at the forefront of customers and legislators minds. Heavy Duty Diesel Engines (HDDE) are the primary source of mechanical power generation in today’s trucks and buses and this is likely to continue for the foreseeable future. READ MORE
