  2. 2. Characterization of an Electrical Sensor for Combustion Diagnostics

    University dissertation from Combustion Physics, Lund Institute of Technology

    Author : Axel Franke; Lunds universitet.; Lund University.; [2002]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; ion sensor; combustion; nitric oxide; chemi-ionization; equilibrium; Physics; ionized gases; Fysicumarkivet A:2002:Franke; ionization sensor; Fysik;

    Abstract : Popular Abstract in Swedish Joniseringssensorn är en elektrisk sensor för diagnostik i förbränningsmotorer. Sensorn används idag för att till exempel detektera knack. Sensorn bygger på att energifrigörelsen i motorn leder till jonisering av olika ämnen, vilket betyder att gasens lednigsförmåga ökar. READ MORE

  3. 3. Combustion Valve Wear A Tribological Study of Combustion Valve Sealing Interfaces

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Peter Forsberg; Uppsala universitet.; [2013]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Combustion valves; wear; tribofilm; test rig; combustion residue; Teknisk fysik med inriktning mot tribomaterial; Engineering Science with specialization in Tribo Materials;

    Abstract : The exhaust valve system of combustion engines experiences a very complex contact situation of frequent impact involving micro sliding, high and varying temperatures, complex exhaust gas chemistry and possible particulates, etc. In addition, the tribological situation in the exhaust valve system is expected to become even worse due to strict future emission regulations, which will require enhanced combustion and cleaner fuels.

  5. 5. Development and application of laser diagnostics - from laboratory devices towards practical combustion engines

    University dissertation from Division of Combustion Physics, Department of Physics, Lund University

    Author : Zhenkan Wang; Lunds universitet.; Lund University.; [2018-05-04]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Combustion diagnostics; Laser induced fluorescence LIF ; Ultra-high-speed; Burst-mode laser; Ballistic imaging; Particle imaging velocimetry; Laser Doppler anemometry; Turbulent premixed combustion; Plasma; Internal combustion engine; Partially premixed combustion PPC ; Auto-ignition; OH radical; CH2O formaldehyde ; Fysicumarkivet A:2018:Wang;

    Abstract : For many decades, research work on combustion has been focused on improving combustion efficiency and reducing harmful emissions. Laser diagnostics is one of the best ways to investigate the combustion process and emission formation as it is non-intrusive and it has high spatiotemporal resolution. READ MORE
