  3. 3. System Simulation of Partially Premixed Combustion in Heavy-Duty Engines : Gas Exchange, Fuels and In-cylinder Analysis

    University dissertation from Energy Sciences, Lund University

    Author : Erik Svensson; Lunds universitet.; Lund University.; [2019-05-20]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Partially Premixed Combustion PPC ; Compression ignition; Direct injection; Methanol; Engine optimization; Stochastic reactor model; T-phi diagrams; Partially premixed combustion; Compression Ignition; Direct Injection; Methanol; Engine Optimization; Stochastic reactor model; Gas exchange; T-phi diagrams;

    Abstract : The concept of partially premixed combustion (PPC), applied to conventional diesel engines, has shown to yield high gross efficiencies and low emissions of oxides of nitrogen and soot. PPC emerged from the knowledge gained from homogeneous charge compression ignition (HCCI) research. READ MORE

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

    University dissertation from Energy Sciences, Lund University

    Author : Lucien Koopmans; [2005]
    Keywords : 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 ;

    Abstract : 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. READ MORE

  5. 5. Alternative Combustion Strategies for Gasoline Engines

    University dissertation from Energy Sciences, Lund University

    Author : Daniel Dahl; [2009]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; engines; SI; SGDI; CAI; HCCI; Otto; lean burn; gasoline; combustion; fuel consumption;

    Abstract : Due to increasingly strict legislative demands and customer concerns regarding CO2emissions, there is a need to develop and implement new combustion strategies forgasoline (Otto) engines. In attempts to meet this need, most attention is focusing onthe low load/speed range where the classic spark ignition strategy (SI) has poorefficiency, mainly due to the throttling of the intake air causing pumping losses.
