  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

    Sammanfattning : The ever increasing demands on today's engine performance and emissions control is forcing the automotive industry to make use of innovative solutions. One of these is to apply the technology of VNT turbos on commercial petrol vehicles. LÄS MER

  4. 3. 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

  5. 4. Variable Stator Nozzle Angle Control in a Turbocharger Inlet

    Master-uppsats, KTH/Kraft- och värmeteknologi

    Författare :Enrique Carrasco Mora; [2015]
    Nyckelord :Turbocharger Radial Turbine Blade Nozzle;

    Sammanfattning : Turbochargers are becoming an essential device in internal combustion engines as they boost the intake air with more pressure in order to increase the power output. These devices are normally designed for a single steady design point but the pulsating flow delivered from the internal combustion engine is everything but steady. LÄS MER

  7. 5. Transient Control of SIDI-Engine with VGT and VVT

    Master-uppsats, KTH/Maskinkonstruktion (Inst.)

    Författare :Erik Klingborg; [2012]
    Nyckelord :;

    Sammanfattning : Today's development of spark ignited (SI) engines is to a large extent focused on downsizing, i.e where a large naturally aspirated engine is replaced with a smaller turbocharged engine with the same output power. LÄS MER
