  2. 16. 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.

  4. 17. Methanol Diesel Dual Fuel Direct Injection in a HD-CI Engine

    Author : Michael Saccullo; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Alcohol Fuels; Heavy Duty Engine; Dual Fuel; Combustion;

    Abstract : Laws concerning emissions from heavy duty (HD) internal combustion engines are becoming increasingly stringent. New engine technologies are needed to satisfy these new requirements and to reduce fossil fuel dependency. READ MORE

  5. 18. Combustion Engine Characterization and Development by Means of Laser Diagnostics

    Keywords : NATURVETENSKAP; NATURAL SCIENCES; framdrivningssystem; Laser technology; Laserteknik; plasma; fluiddynamik; Gaser; plasmas; Gases; fluid dynamics; Motorer; laser engine lif plif; Motors and propulsion systems; Fysicumarkivet A:2002:Richter;

    Abstract : Planar laser induced fluorescence (LIF) has been utilized for two-dimensional imaging in combustion environments. By using tracer LIF the fuel distribution prior to ignition has been monitored in a GDI-engine. READ MORE

  6. 19. 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.

  7. 20. Advancing the understanding of pilot ignition in dual fuel engines : Experimental and conceptual studies

    Author : Menno Merts; Förbränningsmotorer; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Combustion engines; Dual fuel; RCCI; Pilot injection; renewable fuels; Conceptual model; LTC; Heavy duty; Marine; Start of combustion; Optical engine research;

    Abstract : The energy transition is looking for new technologies to reduce CO2 emissions. One of the promising options is the dual fuel engine. In this concept, based on a diesel engine, a small pilot diesel injection is used to ignite a second fuel. READ MORE
