  1. 1. Accuracy of turbocharged SI-engine simulations

    Författare :Fredrik Westin; KTH; []
    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 prime mover in the world today is the Internal Combustion (IC) engine. The development and improvement of the internal combustion engines since Nicolaus August Otto and Rudolf Diesel has continued until today and will continue long into the future. No major competitor to the IC engine has yet emerged. LÄS MER
