  2. 1. Development and Application of Laser Techniques for Studying Fuel Dynamics and NO Formation in Engines

    Author : Öivind Andersson; Förbränningsmotorer; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Motors and propulsion systems; LIF; Laser Diagnostics; Rayleigh Scattering; Fluorescence; Combustion; Pollutant; Nitric Oxide; Spray Combustion; DME; Laserteknik; Laser technology; Motorer; framdrivningssystem; Physics; Fysik; Fysicumarkivet A:2000:Andersson;

    Abstract : Development and application of some laser techniques for the study of engine combustion are presented. The investigations mainly cover two aspects: fuel dynamics and formation of NO. READ MORE

  4. 2. Zero and Multi-Dimensional Modeling of Internal Combustion Engines with respect to Ion Current and Soot Formation

    Author : Abdelhadi Ahmedi; Institutioner vid LTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; engine knock; pollutant emissions; detailed chemical kinetics; thermal ionization.; ion current sensor; method of moments; ionization; soot formation oxidation; modeling; auto-ignition; Spark ignition engine; diesel engine;

    Abstract : The work presented in this thesis can be divided into the three following fields of investigation: First of all the ionization model developed in this thesis is meant to simulate the thermal ionization process or the so-called second peak. Equilibrium assumptions have been adopted for the modeling of the thermal ionization, in which Saha’s equation was derived for singly ionized molecules. READ MORE

  6. 4. Particulate Formation in GDI Engines

    Author : Sreelekha Etikyala; Chalmers tekniska högskola; []
    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; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; PM; Alternate fuels; Gasoline Direct Injection; internal combustion engines; Particulate Number; Load transients;

    Abstract : The need to comply with stringent emission regulations while improving fuel economy and reducing criteria pollutant emissions from transportation presents a major challenge in the design of gasoline Direct Injection (DI) engines because of the adverse effects of ultrafine Particulate Number (PN) emissions on human health and other environmental concerns. With upcoming advances in vehicle electrification, it may be the case that electric vehicles completely replace all current vehicles powered by internal combustion engines ensuring zero emissions.

  7. 5. Decontamination of Mercury from Aqueous Systems via Electrochemical PtHg4 Alloy Formation

    Author : Vera Roth; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Mercury; Platinum; Alloy Formation; Electrochemistry; Mercury Removal;

    Abstract : Mercury is worldwide a severe heavy metal pollutant and a serious threat to human health and ecosystems. Mercury can be released into the environment by various natural processes; however, mercury pollution has been significantly amplified by human activities such as mining, production of fertilizers, waste incineration and disposal.
