  1. 1. Virtual Test Cell : a Real-Time digital twin of an internal combustion engine

    M1-uppsats, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Rasmus Malmqvist; [2024]
    Nyckelord :Virtual Test cell; Digital twin; Software in the loop; Real-time;

    Sammanfattning : As the world is evolving faster and technology gets cheaper and more powerful, simulations are proving to be more and more beneficial. Simulations allow for faster development with less lead time between iterations which means that product versions can be released more often and at less cost. LÄS MER

  3. 2. Development and Application of an End-of-Life Framework

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

    Författare :Daniel Blomberg; David Lorang; [2023]
    Nyckelord :;

    Sammanfattning : As the global climate crisis becomes more urgent, organizations are forced to find ways of reducing their environmental footprint to meet changing climate policies and consumer demands. As the automotive industry is adapting to the shift from internal combustion engines to electrification, as well as the shift from traditional linear business models to circular ones, there is a chance for new actors entering the market to adopt circular business models from their inception, giving them an edge over incumbent firms who have slower adaption times.

  4. 3. Exhaust system for hydrogen fuelled combustion engines: effect of high-water content on the SCR vanadium catalyst

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

    Författare :Cecilia Zambelli; [2023]
    Nyckelord :;

    Sammanfattning : Transportation represents a key secot in the journey towards a greener future, and alternative solutions are needed to meet the decarbonaisation need. Hydrogen internal combustion engines could represent a solution in the short-term, allowing for emission reduction with limited modification to the already existing traditional combustion engines.

  5. 4. High Temperature Tribology of Exhaust Components in Alternative Fuel Engines

    Master-uppsats, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Muhammad Hashir Zaheer; [2023]
    Nyckelord :High temperature tribology; Wear; Friction; Exhaust manifold; Lip seal ring; Wear resistant coatings; Inconel 718c; SiMo51 ductile cast iron; AlTiN; Tribaloy 400;

    Sammanfattning : Internal Combustion Engine (ICE) exhaust components are exposed to extreme operating temperatures. Thus, it is necessary that they are designed with materials that can sustain thermal and vibrational stresses. LÄS MER

  7. 5. EV battery temperature estimation : Designing a model for minimal temperature of high-voltage battery in a BEV

    Uppsats för yrkesexamina på grundnivå, Mittuniversitetet/Institutionen för data- och elektroteknik (2023-)

    Författare :Björn Arvidsson; [2023]
    Nyckelord :BEV; temperature estimation; lowpass filter; BEV; lågpassfilter; temperaturestimering;

    Sammanfattning : Fordonsindustrin är inne i ett skifte, där förbränningsmotorer (ICE) bör-jar fasas ut och det satsas mer på eldrift med hjälp av batterier (BEV).  I detta arbete, som efterfrågades av Volvo Cars, utvecklades en matema-tisk modell som uppskattar den lägsta temperaturen i en elbils högspän-ningsbatteri.
