  2. 16. Application and Development of Optical Soot Diagnostic Techniques

    Author : Ted Lind; Förbränningsmotorer; []
    Keywords : Soot; Soot diagnostics; Soot oxidation; Extinction Imaging; Soot thermometry; Optical diagnostics;

    Abstract : Internal combustion engines (ICE) have been a vital part of society ever since their inception more than a hundred years ago. While initially it seemed as if the replacement of horse and carriage had solved the issue with pollutant emissions, it became evident in the 60’s that emission from ICEs is a major concern.

  4. 17. Low Temperature Combustion in a Heavy Duty Diesel Engine

    Author : Malin Ehleskog; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LIVC; heavy duty; VVA; Diesel engine; Combustion; soot; EIVC; NOx; LTC;

    Abstract : In recent years, there have been major efforts to reduce engine emissions and fuel consumption. The studies described in this thesis were conducted with the aim of identifying methods for reducing harmful engine-out emissions of soot and nitrogen oxides (NOx) under high load without increasing fuel consumption.

  5. 18. Laser-based diagnostics for investigating soot formation in combustion processes

    Author : MANU Mannazhi; Förbränningsfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Soot formation; Laser diagnostics; Combustion; Laser-induced Incandescence; Fysicumarkivet A2022:Mannazhi;

    Abstract : In this work, laser-based diagnostic techniques were developed and applied to investigate soot formation in small-scale laboratory burners as well as in practical combustion devices. Quantitative 2D laser-induced incandescence (LII) measurements often use a cylindrical lens to shape the beam and illuminate the planar region of interest. READ MORE

  6. 19. Investigations of Diesel Sprays in Optical Engines - Liquid Fuel Penetration and Lift-Off Length

    Author : Guillaume Lequien; Förbränningsmotorer; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; high-speed imaging; liquid penetration; lift-off length; soot; optical engine; Diesel sprays;

    Abstract : Diesel engines are widely used as powertrain solutions for transportation vehicles. Their low fuel consumption and high performance make them attractive, however, their associated pollutant emissions is a major drawback which represent a hazard for public health and the environment.

  7. 20. Laser Diagnostics for Applications to In-Cylinder Engine Investigations

    Author : Robert Collin; Förbränningsfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; LII; Rayleigh scattering; formaldehyde; OH; soot; dimethyl ether; Laser technology; Fysik; Laserteknik; Physics; LIF; Laser diagnostics; combustion engines; Fysicumarkivet A:2004:Collin;

    Abstract : In the work presented in the thesis laser diagnostics was employed primarily in the investigation of engines, but was also used to study soot in flames. Quantitative measurements were performed for visualizing both in-cylinder soot formation and DME sprays in a combustion vessel. READ MORE
