2. Full Cycle Cylinder State Estimation in DI Engines with VVA
University essay from Linköpings universitet/FordonssystemAbstract : Tougher legal demands on pollutions require a better developed understanding of the processes that take place in the cylinder. The thesis contributes with a cylinder model that uses the same set of equations for intake, compression,expansion/combustion and exhaust. READ MORE

3. Physically Based Modelling for Knock Prediction in SI Engines
University essay from Linköpings universitet/FordonssystemAbstract : The high demand for an increase in performance and at the same time loweringthe emissions is forcing the automotive industry to increase the efficiency of thevehicles. This demand lead to a problem called knock, which often is the limitingfactor when increasing the efficiency of the engine. READ MORE

4. Effects and Models of Water Injection in an SI Engine
University essay from Linköpings universitet/FordonssystemAbstract : Downsizing and turbocharging is a popular combination nowadays in cars inorder to decrease the fuel consumption. However, the boost pressure increasesthe risk of engine knock, limiting the engine in high-load operating points. Inthe current engines, fuel is used to cool the engine in these operating points,leading to a higher fuel consumption. READ MORE
