  4. 3. HCCI Combustion by Retaining Residuals. Development and Analyses of a Method to Reduce Fuel Consumption for Passenger Car Gasoline Engines

    Författare :Lucien Koopmans; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; gasoline; variable valve timing; homogeneous charge compression ignition HCCI ; internal combustion engines; fuel-consumption; engine emissions; controlled auto-ignition CAI ;

    Sammanfattning : The demand for more powerful engines on one hand, and greater fuel-efficiency on the other, requires a revolution in engine combustion technology. Homogeneous charge compression ignition (HCCI) can be a fuel-saving, low emissions approach that seems to be very suitable for large displacement passenger car engines. LÄS MER

  5. 4. Simulation of Combustion and Mixture Formation for Gasoline Direct Injection Engine Application

    Författare :Chen Huang; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VSB2; Reitz-KHRT; gasoline surrogate; LISA; sensitivity study.; Reitz-Diwakar; Trajectory collision; laminar flame speed; chemical kinetics; TAB; Rosin-Rammler; ignition delay; OpenFOAM; ethanol; O Rourke collision; SMD; hollow cone spray; liquid penetration;

    Sammanfattning : The development and introduction of new engine technologies are primarily motivated by the need to comply with increasingly stringent emissions legislation and to reduce fuel consumption. One of the most important of these new engine technologies is direct gasoline injection, which is considered to be an important and cost-effective measure to meet both targets. LÄS MER

  7. 5. Energy demand management in selected African countries

    Författare :Philip Kofi Adom; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

    Sammanfattning : This thesis contains five empirical papers that contribute to the energy demand management literature on Africa. It investigates the following policy issues – business cycle and energy conservation, government fuel subsidies and energy efficiency, economic growth and environmental quality, structural effects in parameters, the transition between energy efficiency and energy inefficiency, forecast of energy demand, shifts in demand behaviour, and the persistence profile of energy demand to shocks – using data from five countries: Algeria, Nigeria, South Africa, Cameroon and Ghana.
