  2. 1. Accuracy of turbocharged SI-engine simulations

    Author : Fredrik Westin; KTH; []
    Keywords : boosting; turbocharging; supercharging; modelling; simulation; turbine;

    Abstract : 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. READ MORE
