1. 1-D simulation of turbocharged SI engines : focusing on a new gas exchange system and knock prediction
Abstract : 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. READ MORE

2. Theoretical and Experimental Studies of the Formation of Ionized Gases in Spark Ignition Engines
Abstract : The processes that govern the formation, existence and consumption of ions in gases have been studied both experimentally and theoretically. The aim of the work is targeted at increasing the understanding of these phenomena in the working gases inside an engine. READ MORE

5. Empirical combustion modeling in SI engines
Abstract : 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. READ MORE
