  1. 6. 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

  3. 7. Detailed study of steady incylinder flow and turbulence using stereo-PIV

    University essay from KTH/Mekanik

    Author : Julie Vernet; [2012]
    Keywords : ;

    Abstract : Due to the increase of global warming effects and new legislation in terms of consumption and emissions of engines, it is today of paramount importance to know exactly the flow behavior inside cylinders of engines to be able to improve the combustion process. Until now, at Scania, cylinder heads have been tested in terms of flow coefficient measurements and torque measurements using steady flowrigs. READ MORE

  4. 8. Electronics in Support of Combustion Feedback in Heavy-Duty Diesel Engines : An Investigation Using an FPGA-Based Approach

    University essay from KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Author : Jonian Grazhdani; [2011]
    Keywords : ;

    Abstract :           Closed-loop controlled combustion is a promising technique to improve the overall performance of internal combustion engines and Diesel engines in particular. In order for this technique to be implemented some form of feedback from the combustion process is required. READ MORE

  5. 9. Mean Value Model of the Gas Temperature at the Exhaust Valve

    University essay from Institutionen för systemteknik

    Author : Filip Ainouz; Jonas Vedholm; [2009]
    Keywords : medelvärdesmodell; avgasventilen; avgastemperatur;

    Abstract : Over the years many investigations of the gas temperature at the exhaust valve have been made. Nevertheless the modeling of the gas temperature still remains an unsolved problem. READ MORE

  6. 10. Recognizing Combustion Variability for Control of Gasoline Engine Exhaust Gas Recirculation using Information from the Ion Current

    University essay from Sektionen för Informationsvetenskap, Data– och Elektroteknik (IDE)

    Author : Anna Holub; Jie Liu; [2006]
    Keywords : Internal combustion engines; ion current; exhaust gas recirculation; engine control; neural networks; K-nearest neighbour; combustion variability;

    Abstract : The ion current measured from the spark plug in a spark ignited combustion engine is used as basis for analysis and control of the combustion variability caused by exhaust gas recirculation. Methods for extraction of in-cylinder pressure information from the ion current are analyzed in terms of reliability and processing efficiency. READ MORE
