2. 1. Characteristics of Particulate Emissions from Low Temperature Combustion and Renewable Fuels : Aerosol Mass Spectrometry of Refractory Carbonaceous Particles

   Author : Vilhelm Malmborg; NanoLund: Centre for Nanoscience; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Emissions; Soot; BC; BrC; ROS; SP-AMS; MiniCAST; Diesel Engine; HVO; RME; Cook Stove; Emissions; Soot; BC; BrC; SP-AMS; ROS; MiniCAST; Diesel Engine; HVO; RME; Cook Stove;

   Abstract : Particulate air pollution is one of the major causes of premature death in the world, and combustion-derived soot emissions contribute strongly to the particulate pollution to which humans are exposed. Black carbon (BC) is one such emission and denotes soot with strong light absorption in the ultraviolet to infrared spectrum. READ MORE

4. 2. 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

5. 3. The effects of long chain alcohol blends on engine performance and spray characteristics in CI engines

   Author : Josefine Preuss; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; spray characteristics; RME; drop-in bränslen; long chain alcohols; CI engine; HVO;

   Abstract : Replacing fossil fuels with alternatives derived from renewable sources is one way of meeting society’s increasing need for mobility while also significantly reducing greenhouse gas emissions from vehicles with internal combustion engines. To facilitate such a replacement, this thesis presents optical spray studies and engine experiments conducted to evaluate the potential of blends of biomass-derived alcohols and vegetable oils to serve as drop-in fuels for compression ignition engines.

6. 4. Combustion Chemistry Investigation of Liquid and Solid Fuels

   Author : Åsa Håkansson; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; gasoline; flame; GC MS; heptane; combustion; pyrolysis; kinetics; emissions; wood; RME;

   Abstract : The aim of this work was to study the combustion of liquid and solid fuels with the emphasis on intermediates and products. Depending on the structure and the complexity of the fuel different reactors and methods were used. Small-scale laboratory reactors were built and chemical analysis and evaluation methods were developed. Heptane. READ MORE

7. 5. Acute cardiovascular effects of biofuel exhaust exposure

   Author : Jon Unosson; Jenny A Bosson; Anders Blomberg; Jeremy P Langrish; Campen Matthew; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cardiovascular; air pollution; endothelial dyssfunction; arterial stiffness; wood smoke; woodsmoke; biodiesel; RME; biofuel; diesel exhaust;

   Abstract : BackgroundAnthropogenic air pollution is a global health problem estimated to contribute to millions of premature deaths. Exposure to biomass smoke is common due to varying sources, such as wildfires, indoor cooking over open fires, and residential heating from wood stoves. READ MORE
