  1. 1. Filtering Pressure Oscillations in a Common Rail Pressure Signal with IIR Notch Filters for Injected Fuel Amount Estimation

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Marcus Akkila; Denis Ramsden; [2023]
    Nyckelord :DSP; Water hammer effect; IIR; Common-rail; Injected fuel amount estimation; Notch filter; Water hammer effect; IIR; Digital signalbehandling; Injektionsmängd; Common-rail; bandstoppfilter;

    Sammanfattning : This project concerns an inline six-cylinder (I6) diesel truck engine equipped with common-rail injection system. It has been done at the Swedish truck manufacturer Scania CV AB. The main focus is digital signal processing of the rail pressure sensor signal from the injection system. LÄS MER

  3. 2. Investigation of fuel and water injection in gas turbine combustion : Evaluate the methodologies available in Star CCM+ for modeling of water injection in simplified combustor using liquid and gas fuels

    Master-uppsats, Linköpings universitet/Mekanisk värmeteori och strömningslära

    Författare :Sanger Shinwari; [2023]
    Nyckelord :Diesel and Methane fuel combustion; FGM combustion model; Lagrangian multiphase modelling; Inert Stream; Water injection; STAR CCM ;

    Sammanfattning : The negative impact of gas turbine emissions on the environment and human health is a growing concern. Recent studies suggest injecting water into the combustion process effectively reduces emissions and increases power output. However, this approach presents new challenges that need to be thoroughly investigated. LÄS MER

  4. 3. Design of Experiment Based on Full Factorial CFD Spray Modelling

    Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

    Författare :Olle Faritzon; [2023]
    Nyckelord :CFD; spray; liquid; injection; DoE; Design of Experiment; fuel spray; Propane; LPG; OpenFOAM; Experiment; Fluid dynamics; maritime shipping; engine; Technology and Engineering;

    Sammanfattning : Design of experiment is a powerful tool that can reduce the amount of physical testing needed to save resources, time and money. A CFD-setup was constructed in OpenFOAM-8, simulating injection of liquid propane with a standard multi-hole injector. The model was then validated against experimental results. LÄS MER

  5. 4. 3D CFD Simulations of Hydrogen Engine Combustion

    Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

    Författare :Hao Liu; [2023]
    Nyckelord :Technology and Engineering;

    Sammanfattning : With the trend of decarbonization, the transport sector is exploring possibilities of fossil fuel free solutions. Hydrogen can be a potential fuel for future engine applications. In this work, the concept of H2 HPDI is investigated, where a pilot diesel injection ignites the hydrogen jet. LÄS MER

  7. 5. Förnybara drivmedel och deras förutsättningar för implementering i Försvarsmakten

    Uppsats för yrkesexamina på grundnivå, Försvarshögskolan

    Författare :Klara Söderberg; [2022]
    Nyckelord :Renewable fuels; Swedish Armed Forces; FAME; HVO; Biogas; DME; Förnybara drivmedel; Försvarsmakten; FAME; HVO; biogas; DME;

    Sammanfattning : Today’s society is adapting to reduce the climate footprint which is why the Swedish Armed Forces is expected to revise its use of fossil fuel. The choice of fuel is not obvious, and this report aims to examine the possibilities and limitations for a few renewable fuel’simplementation in the Swedish Armed Forces. LÄS MER
