  2. 1. 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

  4. 2. Oil-related Particle Emissions from Diesel Engines

    Author : Petter Johansson; Sören Andersson; KTH; []
    Keywords : Diesel engine; Particle emissions; Particulate matter; PM; Lubrication oil; Inter-ring pressure; TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : In recent decades much effort has gone into reducing particle emissions in the exhaust gases of heavy-duty diesel engines. Engine development has now reached the stage where it is worth to put heavy focus on the contribution of lubricating oil to particulate emissions in order to further reduce these emissions.

  5. 3. Particle emissions from residential wood and biodiesel combustion

    Author : Robin Nyström; Christoffer Boman; Dan Boström; Markus Broström; Michael Strand; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Combustion; biomass; wood; biodiesel; particulate matter; emissions; aerosols; physicochemical properties; size distribution; PAH;

    Abstract : Emissions from anthropogenic combustion sources, such as vehicles and biomass combustion, contribute significantly to ambient particulate matter (PM) both on a local and global scale. Exposure to ambient PM and air pollution in general is linked to a variety of different health effects and it has been estimated that as many as 2. READ MORE

  6. 4. Particulate and gaseous emissions from residential biomass combustion

    Author : Christoffer Boman; Anders Nordin; Ingwald Obernberger; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Chemistry; aerosols; air pollution; emissions; fuel pellets; residential biomass combustion; inorganic characterization; incomplete combustion; particulate matter; polycyclic aromatic hydrocarbons; trace elements; Kemi; Chemistry; Kemi;

    Abstract : Biomass is considered to be a sustainable energy source with significant potentials for replacing electricity and fossil fuels, not at least in the residential sector. However, present wood combustion is a major source of ambient concentrations of hydrocarbons (e.g. READ MORE

  7. 5. The Regulation of Global SOx Emissions from Ships: IMO proceedings 1988-2008

    Author : Erik Svensson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; IMO; SOx; global cap; Annex VI; MARPOL; air pollution; ships; sulphur oxides; policy-making; emissions;

    Abstract : MARPOL Annex VI regulates air pollution from international shipping. Emissions of sulphur oxides (SOx) are regulated through a global limit for the sulphur content of bunker fuels (referred to as a global cap) as well as a stricter limit in particularly sensitive areas, referred to as SOx Emission Control Areas (SECAs).
