3. 2. 1D engine simulation of a turbocharged SI engine with CFD computation on components

   Författare :Ulrica Renberg; Hans-Erik Ångström; Laszlo Fuchs; Per Birkestad; KTH; []
   Nyckelord :1D modeling; CFD modeling; turbine efficiency; pipe flow; turbocharged engine; TECHNOLOGY; TEKNIKVETENSKAP;

   Sammanfattning : Techniques that can increase the SI- engine efficiency while keeping the emissions very low is to reduce the engine displacement volume combined with a charging system. Advanced systems are needed for an effective boosting of the engine and today 1D engine simulation tools are often used for their optimization. LÄS MER
