  1. 1. Artificial Neural Network in Exhaust Temperature Modelling : Viability of ANN Usage in Gasoline Engine Modelling

    Master-uppsats, Linköpings universitet/Fordonssystem; Linköpings universitet/Tekniska fakulteten

    Författare :Musa Nibras; Roos Linus; [2022]
    Nyckelord :Artificial Neural Network; Data-driven Modelling; Engine Modelling; Transient behaviour; Static behaviour; Feed Forward Network; Layer Recurrent Network; NARX; Long Short Term Memory; Gated Recurrent Network; Data processing;

    Sammanfattning : Developing and improving upon a good empirical model for an engine can be time-consuming and costly. The goal of this thesis has been to evaluate data-driven modelling, specifically neural networks, to see how well it can handle training for some static models like the mass flow of air into the cylinder, mean effective pressure and pump mean effective pressure but also for transient modelling, specifically the exhaust gas temperature.

  3. 2. Elbilar, en livscykelanalysav två alternativa tekniker : Bränslecellsbilar och batteribilar

    Master-uppsats, Uppsala universitet/Materialfysik

    Författare :Simon Nordén; [2021]
    Nyckelord :Fuel Cell Vehicle; Battery Electric Vehicle; Life Cycle Assessment; Electrolysis; Bränslecellsbil; Batteribil; Livscykelanalys; Elektrolys;

    Sammanfattning : In this thesis, two electric vehicles are compared, a fuel cellpowered vehicle and a battery powered vehicle with a conventionalvehicle with an internal combustion engine. The comparison wasdone as a life cycle assessment and consisted of two stages, avehicle stage and a fuel stage. LÄS MER

  4. 3. Model-Predictive Control of Gas Exchange in a Gasoline Engine

    Master-uppsats, Linköpings universitet/Fordonssystem

    Författare :George Jajji; [2021]
    Nyckelord :Control Engineering; Model Predictive Control; MPC; Gasoline Engine; Gas Exchange;

    Sammanfattning : The process to induct air into engine cylinders, via the air inlet system and cylin-der port valves, is referred to as the "gas-exchange". Control is achieved by theturbo-charger, the intake throttle plate and the variable valve timing (VVT) sys-tem. These actuation systems traditionally use separate control with indepen-dent SISO feedback. LÄS MER

  5. 4. A solution to misfuelling and a new experience in car refueling.

    Master-uppsats, Högskolan i Jönköping/JTH, Industridesign

    Författare :Stefanos Stefou; [2020]
    Nyckelord :Misfuelling; gas pump; diesel; gasoline; engine; Statoil; fuel; refueling; industrial design;

    Sammanfattning : The purpose of this thesis is to clarify to the reader the problem of misfuelling, which is the insertion of the wrong fuel in an engine, incompatible with the fuel inserted. Additionally, it contains research about the causes of this problem, current solutions in the market and a suggested solution according to the prior research and the findings of this thesis. LÄS MER

  7. 5. Vilket gräs är grönare? En litteraturöversikt kring nytillverkade och begagnade personbilars totala klimatpåverkan för olika drivmedel

    Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)

    Författare :Jimmy Chaundy; Niklas Björk; [2019]
    Nyckelord :;

    Sammanfattning : Människan har generellt ett behov av att transportera sig. I Sverige sker en betydande del av dessa med bil. För sträckor som är orimligt långa för gång och cykling bortom kollektivtrafiksnätet kommer behovet av bil att kvarstå. Transport med samtliga typer av dagens bilar har dock betydande klimatpåverkan.
