  1. 1. A GENeric Internal Combustion Engine model : LiU-Genie

    Master-uppsats, Linköpings universitet/Fordonssystem

    Författare :Oskar Lind Jonsson; [2021]
    Nyckelord :;

    Sammanfattning : As the demand for control in modern vehicles grows, models are needed to develop a better understanding of processes and engine behavior. The thesis contributes with a generic extended MVEM with SI and CI as well as VVA compatibility and modeling structure using MATLAB/Simulink environment. LÄS MER

  3. 2. Exhaust Temperature Modeling and Optimal Control of Catalytic Converter Heating

    Master-uppsats, Linköpings universitet/Fordonssystem

    Författare :Victor Petersson; [2019]
    Nyckelord :cold-start; catalyst heating; ignition retardation; GDI;

    Sammanfattning : After reaching its light-off temperature, the catalytic aftertreatment system plays a major part in maintaining emissions at low levels for vehicles equipped with combustion engines. In this thesis, modelling of the exhaust gas temperature is investigated along with optimal control strategy for variable ignition and exhaust valve opening angles for optimal catalytic converter heating.

  4. 3. Insugstrycksreglering av turbomotoriserade dragracingmotorcyklar

    Kandidat-uppsats, Linköpings universitet/Fordonssystem

    Författare :Kalle Torniainen; [2019]
    Nyckelord :Turbo; Tryckreglering;

    Sammanfattning : Vid acceleration från stillastående med en turbomotoriserad dragracingmotorcykel behöver motorcykelns insugstryck regleras. Om regleringen av insugstrycket inte lyckas uppstår en okontrollerad och hastig ökning av insugstrycket. En för hastig ökning av insugstrycket leder till att vridmomentet från motorn ökar snabbare än önskat. LÄS MER

  5. 4. Compressible Flow Modeling with Combustion Engine Applications

    Master-uppsats, Linköpings universitet/Fordonssystem

    Författare :Carl Vilhelmsson; [2017]
    Nyckelord :Compressible; Flow; Modeling; Combustion; Engine; Throttle; EGR; Wastegate; Valves; Gas;

    Sammanfattning : The high demands on low fuel consumption and low emissions on the combustion engines of both today, and the future, is highly dependent on advanced control systems in order to fulfill these demands. The control systems and strategies are based on models which describe the physical system. LÄS MER

  7. 5. Model Based Control of Throttle, EGR and Wastegate : A System Analysis of the Gas Flows in an SI-Engine

    Master-uppsats, Linköpings universitet/Fordonssystem

    Författare :Henrik Andersson; [2017]
    Nyckelord :Model; Control; SI-engine; gas-flow; system analysis;

    Sammanfattning : Due to governmental requirements on low exhaust gas emissions and the drivers request of fast response, it is important to be able to control the gas flow in a spark ignited engine accurately. The air into the cylinder is directly related to the torque generated by the engine. LÄS MER
