  4. 2. HCCI Combustion - Engine Operation and Emission Characteristics

    Author : Magnus Christensen; Förbränningsmotorer; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Motorer; framdrivningssystem; Motors and propulsion systems; efficiency; emissions; combustion; HCCI; engine;

    Abstract : The potential and limitations of the Homogeneous Charge Compression Ignition (HCCI) engine concept has been experimentally investigated. The operation range, in terms of usable air/fuel ratio and engine load, and the emission characteristics have been studied. An 1. READ MORE

  5. 3. Characterization of the Combustion of Light Alcohols in CI Engines : Performance, Combustion Characteristics and Emissions

    Author : Sam Shamun; Förbränningsmotorer; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Methanol; Ethanol; Oxygenated Fuel Blends; Compression Ignition Engine; Partially Premixed Combustion; Combustion Characteristics; Efficiency; Emissions; Particulate Matter; Metanol; Etanl; Oxygenerade Bränsleblandningar; Kompressionsantänd Motor; Partiellt Förblandad Förbränning; Förbränningsegenskaper; Verkningsgrad; Emissioner; Partiklar;

    Abstract : Alternative fuels for combustion engines are becoming increasingly popular as society is pushing to phase out fossil energy to reduce CO2 emissions. The compression ignition (CI) engine has a high overall efficiency which makes it a valuable option for the transport fleet, despite the well known NOx and soot pollutants it emits. READ MORE

  7. 5. Disturbances in Fixed-Bed Combustion

    Author : Sven Hermansson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CFD; modelling; packed bed; bed; combustion; channelling; grate furnace;

    Abstract : Conversion of solid fuels in fixed beds is a common method for heat and power production. A frequent fixed-bed technique in small to medium scale is combustion in grate furnaces. Grate furnaces are widely used in the industrial energy branch and appreciated for their stability and simplicity of control. READ MORE
