  1. 1. Laminar Burning Velocity and Development of a Chemical Kinetic Model for Small Oxygenated Fuels

    Author : Moah Christensen; [2016]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Oxygenated fuels; Kinetic mechanism; Validation; Sensitivity; Laminar burning velocity; Heat flux method; Fysicumarkivet A:2016:Christensen;

    Abstract : The thesis work was performed with the aim of increasing knowledge and understanding of the combustion of oxygenated fuels and intermediates. This was accomplished in two steps: experimental measurements of the laminar burning velocity to expand current databases and development of a reaction mechanism. READ MORE

  2. 2. Impact of Fuel Properties on Partially Premixed Combustion

    Author : Hadeel Solaka; [2014]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; PPC; Reference Fuels; Gasline; Diesel; Ignition Delay; Quadratic Regression Model;

    Abstract : Compression ignited engines generally have higher efficiency than spark ignition engines. However, the most common combustion concept in compression ignited engines, conventional diesel combustion, struggles with high levels of particulate matter and NOx emissions. READ MORE

  3. 3. Chemistry of Combustion Products Investigation of Combustion Chamber Deposits Formed in a Gasoline Direct Injection Stratified Charge SI Engine

    Author : Farshid Owrang; [2004]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; gasoline fuels; SI engine; gasoline direct injection; stratified charge; combustion chamber deposits; engine oil; oxidation; in situ measurement; thermal desorption; GC MS; fast neutron activation analysis; spin-lattice relaxation constant; NMR;

    Abstract : The aim of this work was to characterize deposits formed in the combustion chambers of a gasoline direct injection stratified charge SI engine. The engine was run with several types of gasoline fuels and a special reference engine oil. READ MORE

  4. 4. Particulate Formation in Gasoline Direct Injection Engines

    University dissertation from Gothenburg : Chalmers tekniska högskola

    Author : Sreelekha Etikyala; [2019]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Volatileorganic compounds; Particulate Number; Alternate fuels; Gasoline Direct Injection; PM;

    Abstract : Gasoline direct injection (GDI) engines are facing a great challenge because of the need to comply with increasingly stringent emission regulations while improving fuel economy. GDI engines are popularly known for their high fuel efficiency (by the standards of gasoline engines) and low emissions, enabling higher compression ratios and thus increased volumetric efficiency.

  5. 5. Pyrolysis of mixed plastics and paper to produce fuels and other chemicals

    University dissertation from KTH Royal Institute of Technology

    Author : Nanta Sophonrat; Weihong Yang; Linda Sandström; Tobias Richards; [2019]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Pyrolysis; Mixed plastics and biomass; Cellulose; Refuse derived fuels RDF ; Paper rejects; Interactions; Stepwise pyrolysis; Calcium oxide CaO ; Chemical Engineering; Kemiteknik; Energiteknik; Energy Technology;

    Abstract : As the world population and economy grow, higher consumption results in higher waste packaging, plastics and paper residues. Pyrolysis offers a way to recover fuels and other chemicals from this waste fraction. READ MORE
