    Sammanfattning : This thesis work concerns methods for improved spectroscopy including stray-light suppression, dynamic range improvement and signal enhancement. These methods were applied in Raman and Thomson- scattering spectroscopy in combustion and plasma. LÄS MER

  3. 28. Stochastic Knock Control for Improved Efficiency

    Master-uppsats, Linköpings universitet/Fordonssystem

    Författare :Jonas Vedin; Robert Widén; [2019]
    Nyckelord :Knock control; Stochastic knock control; Knock simulation;

    Sammanfattning : Increasing the efficiency and performance of internal combustion engines is always of interest in the automotive industry. One limiting factor to achieve this in gasoline combustion engines is the ignition timing which can not always be set where optimal ignition efficiency and performance is obtained. LÄS MER

  4. 29. Evaluation of Different Concepts for Pressed and Sintered Connecting Rods

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Mattias Rehn; [2019]
    Nyckelord :Connecting Rod; Con Rod; Fatigue; Buckling; Manufacturing; Höganäs AB; CAD; FEM; FEA;

    Sammanfattning : Connecting rod are found in most combustion engines and transmits thrust from the piston to the crankshaft. The connecting rod needs to withstand forces from the piston and inertia forces which results in axial tension, compression stresses and bending. LÄS MER

  5. 30. Combustion Simulations with reduced mechanisms using hybrid optimization

    Kandidat-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Förbränningsfysik

    Författare :Marius Burman Ingeberg; [2018]
    Nyckelord :Optimization; Reduced mechanism; Hybrid optimization; simulated annealing; Genetic algorithm; Physics and Astronomy;

    Sammanfattning : In order to simulate complex combustion systems, the kinetic mechanisms describing the chemical processes have to be reduced. To minimize the error introduced by the reduction, coefficients of the reaction rates included in the mechanisms can be adjusted in ways so that simulations using the reduced mechanism behave like simulations that use detailed mechanisms.
