  4. 2. In-Cylinder Fluid Flow, Fuel Preparation and Combustion in SI Engines - Application of Optical Diagnostics

    Author : Martin Ekenberg; Förbränningsmotorer; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Laserteknik; vakuumteknik; vibrationer; akustik; Motors and propulsion systems; Motorer; hydraulik; Maskinteknik; PIV; vibration and acoustic engineering; hydraulics; vacuum technology; Mechanical engineering; framdrivningssystem; Laser technology;

    Abstract : In this thesis laser-based measurements of in-cylinder flow and fuel concentrations in two stroke and direct injected four-stroke engines are presented. The major problem with the carburetted two-stroke engine is the short-circuiting of fuel that occurs during the scavenging phase. This leads to large emissions of unburned hydrocarbons. READ MORE

    Author : Magnus Pålsson; Förbränningsmotorer; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; vibration and acoustic engineering; Maskinteknik; vakuumteknik; vibrationer; akustik; Motors and propulsion systems; Motorer; framdrivningssystem; hydraulik; Mechanical engineering; hydraulics; vacuum technology; termodynamik; Termisk teknik; applied thermodynamics; Thermal engineering; heat pipe; ejector; solar energy; CGR; recirculation; EGR; catalytic combustion; premix combustion; Stirling engine; combustor;

    Abstract : The main objective in the research described in this thesis was to design and test the use of lean premixed combustion using combustion gas recirculation for gas fuelled Stirling engine combustors. A system using a flame-arrester type of flame-holder to stabilize the flame and an ejector system for the recirculation of combustion gas was designed and tested in the laboratory. READ MORE
