  4. 3. Model-Based Control of Gasoline Partially Premixed Combustion

    Författare :Gabriel Ingesson; Institutionen för reglerteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Pressure-Sensor Feedback; Model Predictive Control; Model-Based Controller Design; Partially Premixed Combustion;

    Sammanfattning : Partially Premixed Combustion (PPC) is an internal combustion engine concept that aims to yield low NOx and soot emission levels together with high engine efficiency. PPC belongs to the class of low temperature combustion concepts where the ignition delay is prolonged in order to promote the air-fuel-mixture homogeneity in the combustion chamber at the start of combustion.

  5. 4. Force and Flow Characteristics of a Partially Submerged Propeller

    Författare :Niclas Olofsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; partially submerged propellers; performance prediction theory; inclined propellers; dynamic blade loads; yawed propellers; blade vibration;

    Sammanfattning : Model experiments have been conducted to determine the average and dynamic performance of a high-speed partially submerged propeller. The purpose of the experiments was to examine the influence of shaft yaw and inclination angles on the propeller characteristics at different Froude and cavitation numbers and to study the flow around the propeller blades in different conditions.

  7. 5. Characterization and Control of Multi-Cylinder Partially Premixed Combustion

    Författare :Magnus Lewander; Förbränningsmotorer; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Efficiency estimation; Closed-loop control; EGR; Diesel engine; Partially Premixed Combustion; Combustion control;

    Sammanfattning : In the last decade diesel combustion has developed in a new direction. Research has been carried out trying to prolong the ignition delay and enhance fuel/air premixing to avoid diffusion combustion as well as lowering the combustion temperature through use of EGR. One of these new combustion concepts is Partially Premixed Combustion (PPC). LÄS MER
