1. 1-D simulation of turbocharged SI engines : focusing on a new gas exchange system and knock prediction
Sammanfattning : This licentiate thesis concerns one dimensional flow simulation of turbocharged spark ignited engines. The objective has been to contribute to the improvement of turbocharged SI engines’ performance as well as 1 D simulation capabilities. Turbocharged engines suffer from poor gas exchange due to the high exhaust pressure created by the turbine. LÄS MER
2. A drivetrain simulation module for turbocharged engines
Sammanfattning : .... LÄS MER
3. Air charge estimation in turbocharged spark ignition engines
Sammanfattning : Turbocharged (TC) spark-ignited (SI) engines are popular as they combine high power output with good fuel economy. Furthermore, their emissions can be successfully reduced using a three way catalyst (TWC) provided that the air-fuel ratio is precisely controlled. LÄS MER
4. Empirical combustion modeling in SI engines
Sammanfattning : This licentiate thesis concerns the modeling of spark ignition engine combustion for use in one dimensional simulation tools. Modeling of knock is of particular interest when modeling turbocharged engines since knock usually limits the possible engine output at high load. LÄS MER
5. Simulation of turbocharged SI-engines - with focus on the turbine
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
