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

    Master-uppsats, Linköpings universitet/Fordonssystem

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

    Sammanfattning : 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. LÄS MER

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

    Master-uppsats, KTH/Mekanik

    Författare :Julie Vernet; [2012]
    Nyckelord :;

    Sammanfattning : 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. LÄS MER

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

    Master-uppsats, KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Författare :Jonian Grazhdani; [2011]
    Nyckelord :;

    Sammanfattning :           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. LÄS MER

  5. 9. CFD simulering av en fyrtakts Otto motorcykel motor

    Master-uppsats, KTH/Maskinkonstruktion (Inst.)

    Författare :Stefan Gundmalm; [2009]
    Nyckelord :;

    Sammanfattning : This thesis deals with the numerical 3D simulation of a four stroke, spark-ignited, internal combustion engine, which is mounted on a high performance motorcycle. The work, carried out in collaboration with Politecnico di Milano and MV Agusta, focuses on the simulation of the intake, compression and expansion stroke, including combustion simulation, using an open source CFD code.

  7. 10. Mean Value Model of the Gas Temperature at the Exhaust Valve

    Uppsats för yrkesexamina på avancerad nivå, Institutionen för systemteknik

    Författare :Filip Ainouz; Jonas Vedholm; [2009]
    Nyckelord :medelvärdesmodell; avgasventilen; avgastemperatur;

    Sammanfattning : 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. LÄS MER
