3. 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

5. Ion Current Dependence on Operating Condition and Ethanol Ratio
University essay from Institutionen för systemteknikAbstract : This masters thesis investigates the possibility to estimate the ethanol content in the fuel using ion currents. Flexible fuel cars can be run on gasoline-ethanol blends with an ethanol content from0 to 85 percentage. It is important for the engine control system to have information about the fuel. READ MORE
