    Abstract : New combustion engine principles increase the demands on feedback combustion control, at the same time economical considerations currently enforce the usage of low-end control hardware limiting implementation possibilities. Significant development is simultaneously and continuously carried out within the field of Field Programmable Gate Arrays (FPGAs). READ MORE

  2. 2. 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; Lunds universitet.; Lund University.; [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.

  4. 4. Predictive Control of HCCI Engines using Physical Models

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

    Author : Anders Widd; Lunds universitet.; Lund University.; [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

    Abstract : Due to increasingly strict emission legislation and stronger demands on fuel consumption, typical passenger car diesel engines become increasingly complex with more and more controllable systems added. These added systems open up for the possibility to operate the engine at more efficient conditions, but it also becomes more challenging to optimize the settings in the engine management system.
