1. 1. On-Engine Turbocharger Performance Considering Heat Transfer

   Författare :Habib Aghaali; Hans-Erik Ångström; Jose R. Serrrano; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; turbocharger; Internal combustion engine; heat transfer; turbocharged engine; on-engine turbocharger; turbocharger performance; توربو شارژر، موتور احتراق داخلی، انتقال حرارت، توربوچارجر; turbo; turboladdare; förbränningsmotor; värmeöverföring; turboladdad motor;

   Sammanfattning : Heat transfer plays an important role in affecting an on-engine turbocharger performance. However, it is normally not taken into account for turbocharged engine simulations. LÄS MER

3. 2. Turbocharged HCCI Engine, Improving Efficiency and Operating Range

   Författare :Thomas Johansson; Förbränningsmotorer; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HCCI; NVO; turbo; direct injection; combustion; CAI; low temperature; simulation; engine;

   Sammanfattning : Increasing fuel prices and environmental concern drives the research and development for the internal combustion engine. Homogeneous Charge Compression Ignition (HCCI) is a promising combustion concept with high fuel efficiency and low emissions. LÄS MER

4. 3. 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

5. 4. 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
