  1. 6. Reduced models for flows in IC-engines

    Författare :Niklas Winkler; Hans-Erik Ångström; Angelo Onorati; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The finite response time of the turbocharger is the most notable effect of transient operation on a turbocharged diesel engine. To fulfill future emission requirements, high amounts of transient EGR will be required even though after-treatment devices are being used. LÄS MER

  3. 7. Diluted Operation of a Heavy-Duty Natural Gas Engine - Aiming at Improved Effciency, Emission and Maximum Load

    Författare :Mehrzad Kaiadi; Förbränningsmotorer; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Turbulence; Natural gas engine; Dilution limit; VGT; Cyclic variation; Closed-loop control; Heavy-duty;

    Sammanfattning : Most heavy-duty engines are diesel operated. Severe emission regulations, high fuel prices, high technology costs (e.g. catalysts, fuel injection systems) and unsustainably in supplying fuel are enough reasons to convenience engine developers to explore alternative technologies or fuels.

  4. 8. Simulation of turbocharged SI-engines - with focus on the turbine

    Författare :Fredrik Westin; Hans-Erik Ångström; Gordon P Blair; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Engineering design; turbocharging simulation 1D turbine accuracy SI-engine; Konstruktionsteknik; Construction engineering; Konstruktionsteknik;

    Sammanfattning : The aim is to share experience gained when simulating (and doing measurements on) the turbocharged SI-engine as well as describing the limits of current state of the technology. In addition an overview of current boosting systems is provided. LÄS MER
