  1. 1. Control Structures for Low-Emission Combustion in Multi-Cylinder Engines

    University dissertation from Department of Automatic Control, Lund Institute of Technology, Lund University

    Author : Maria Henningsson; Lund University.; Lunds universitet.; [2008]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LQG control; fumigation; mid-ranging control; HCCI engine; engine control;

    Abstract : Traditionally, heavy-duty diesel engines have high efficiencies but also high emissions of NOx and soot particles. New engine concepts show the potential to retain diesel-like efficiencies while reducing emissions by forming a completely or partially homogeneous mixture of fuel and air prior to ignition through compression.

  2. 2. Predictive Control of HCCI Engines Using Physical Models

    University dissertation from Department of Automatic Control, Lund Institute of Technology, Lund University

    Author : Anders Widd; Lund University.; Lunds universitet.; [2009]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Model Predictive Control; HCCI engine; engine control;

    Abstract : Homogeneous Charge Compression Ignition (HCCI) is a promising internal combustion engine concept. It holds promise of combining low emission levels with high efficiency. However, as ignition timing in HCCI operation lacks direct actuation and is highly sensitive to operating conditions and disturbances, robust closed-loop control is necessary. READ MORE

  3. 3. Closed-Loop Control of HCCI Engine Dynamics

    University dissertation from Department of Automatic Control, Lund Institute of Technology (LTH)

    Author : Johan Bengtsson; Lund University.; Lunds universitet.; [2004]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; robotteknik; Automatiska system; reglerteknik; Automation; robotics; control engineering;

    Abstract : The topic of the thesis is control of Homogeneous Charge Compression Ignition (HCCI) engine dynamics. HCCI offers a potential to combine high efficiency with very low emissions. In order to fulfill the potential benefits, closed-loop control is needed. READ MORE

  5. 5. Energy Efficient Longitudinal Control

    University dissertation from Gothenburg : Chalmers tekniska högskola

    Author : Rickard Arvidsson; [2018]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Autonomous Vehicles; Optimal Control; Hybrid drivetrain control; Combustion Engines;

    Abstract : Vehicles are contributing to global and local environmental problems as a result of fossil fuels. A majority of the combustion engine population is driven by fossil fuels and electrified vehicles are also to a large extent dependent on electricity production from fossil fuels. READ MORE
