  5. 4. Crank Angle Based Virtual Cylinder Pressure Sensor in Heavy-Duty Engine Application

    University essay from Linköpings universitet/Fordonssystem

    Author : Mikael Gustafsson; [2015]
    Keywords : CLCC; in-cylinder pressure; cylinder separation; torsion.;

    Abstract : The in-cylinder pressure is an important signal that gives information about the combustion process. To further improve engine performance, this information can be used as a feedback signal in a control system. Usually a pressure sensor is mounted in the cylinder to extract this information.

  6. 5. Virtual Sensors for Combustion Parameters Based on In-Cylinder Pressure

    University essay from Linköpings universitet/Fordonssystem

    Author : Tobias Johansson; [2015]
    Keywords : CLCC; virtual sensors; combustion parameters; in-cylinder pressure; heat release; heat-release; heavy duty vehicle;

    Abstract : Typically the combustion in engines are open-loop controlled. By using an in-cylinder pressure sensor it is possible to create virtual sensors for closed-loop combustion control (CLCC). With CLCC it is possible to counteract dynamic effects as component ageing, fuel type and cylinder variance. READ MORE
