  1. 1. Accuracy of turbocharged SI-engine simulations

    Detta är en avhandling från Stockholm : Maskinkonstruktion

    Författare :Fredrik Westin; KTH.; [2002]
    Nyckelord :boosting; turbocharging; supercharging; modelling; simulation; turbine;

    Sammanfattning : This licentiate thesis deals mainly with modelling ofturbocharged SIengines. A model of a 4-cylinder engine was runin both steady state and transient conditions and the resultswere compared to measured data. Large differences betweenmeasurements and simulations were detected and the reasons forthis discrepancy were investigated. LÄS MER

    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

  4. 4. Transient simulations of heavy-duty diesel engines with focus on the turbine

    Detta är en avhandling från Stockholm : KTH

    Författare :Niklas Winkler; KTH.; [2008]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : The finite response time of the turbocharger is the most notable effect oftransient operation on a turbocharged diesel engine. To fulfil future emission requirements high amounts of transient EGR will be required. LÄS MER

  5. 5. Divided Exhaust Period on Heavy-Duty Diesel Engines

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Stefan Gundmalm; KTH.; [2013]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Due to growing concerns regarding global energy security and environmental sustainability it is becoming increasingly important to increase the energy efficiency of the transport sector. The internal combustion engine will probably continue to be the main propulsion system for road transportation for many years to come. LÄS MER
