  1. 1. Electrically Assisted Turbocharger: Modelling And Control Strategy

    Master-uppsats, Linköpings universitet/Fordonssystem

    Författare :Erik Vandor; Gabriel Ehlin; [2022]
    Nyckelord :EAT; VGT; VNT; Hybrid powertrain; electric turbocharger;

    Sammanfattning : A major cause of CO2 emissions today is fossil fuel vehicles, and lowering these emissions is of key importance, resulting in increasing electrification and hybridisation nowadays. Turbochargers have been used for a long time to recycle exhaust gas heat losses to improve engine performance by compressing the intake air. LÄS MER

  3. 2. Turbo For Fuel Cell Electric Vehicle

    Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

    Författare :Adam Hansson; Mohammed Abu Al-Soud; [2022]
    Nyckelord :Turbo; Fuel Cell; Centrifugal Compressor; Radial Turbine; Axial Turbine; Technology and Engineering;

    Sammanfattning : Turbo systems have long been implemented into vehicles to increase the specific power. Increasing the pressure for conventional vehicles decreases the mass of the engine and increases the efficiency. Conventional vehicles do however produce carbon dioxide emissions which have become an increasing issue that needs a solution. LÄS MER

  4. 3. Compressor Surge: Simulation, Modeling and Analysis

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

    Författare :Robin Massiquet; [2022]
    Nyckelord :Turbo compressor; Surge; Simulation; Modelling;

    Sammanfattning : The master thesis subject takes place in the automotive industry and specifically in the internal combustion engine area. The need of improving the efficiency of the engines leads to develop new technologies like turbo compressors. Some of the challenges to overcome are high rotational speed difficulties or extreme load and fatigue in the rotors. LÄS MER

  5. 4. Performance Investigation & Gas Exchange Assessment of Exhaust Piston–assisted Turbocharged Engine (EPTE) Concept : A simulation-based assessment

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

    Författare :Nachiketh Lingachari Acharya; Saurav Dasgupta; [2021]
    Nyckelord :;

    Sammanfattning : There is an increasing stringency in the emission legislation within the transport industry along with ambitious performance demands from the customer side. These have pushed the vehicle manufacturers and relevant component suppliers to develop and integrate a wide portfolio of engine technologies. LÄS MER

  7. 5. Throughflow Study on Bleeding for Part Load Compressor Operation

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

    Författare :Simon Hedkvist; [2019]
    Nyckelord :Compressor; Minimum environmental load; Aerodynamic; Throughflow; Stability; Bleeding;

    Sammanfattning : The transition of the European energy grid to renewable energy sources is increasing the demand for back-up capacity with high flexibility. Current fossil fuel plants are continuously being forced into part load operation, where they are limited by pollution regulations that dictate their minimum environmental load, MEL. LÄS MER
