1. Evaluation of a Variable Nozzle Turbine Turbocharger on a Diesel Engine under Steady and Transient Conditions
Abstract : The growing global call for reduced emissions and fuel consumption together with the market call for engines with higher power density and application-oriented torque curves can be met using turbochargers with variable geometry turbines (VGT). The second generation of VGT turbochargers is currently being developed and is starting to appear on the market. READ MORE

2. Embedded Systems and FPGAs for Implementation of Control Oriented Models, Applied to Combustion Engines
Abstract : Performance demands put on combustion engines are ever increasing, e.g. demands on emissions and fuel consumption. The increased demands together with new combustion concepts increase the need for feedback engine and combustion control. READ MORE

3. On CFD-Analysis of Heat Transfer of a Heavy-Duty Diesel Engine
Abstract : In this work, a heavy-duty diesel engine was studied by employing CFD simulations on a closed volume engine segment. These simulations were used to evaluate both the effects from certain parameters on the wall heat transfer, and to examine how reduction of heat transfer would effect the engine performance and emission levels.

4. Thermodynamic Simulation of HCCI Engine Systems
Abstract : This thesis focuses on engine system simulation using thermodynamics and chemical kinetic models to investigate the performance and efficiency of Homogeneous Charge Compression Ignition (HCCI) engines for stationary applications. It includes the development of software as well as models for engine, turbocharger, intercooler, inlet and exhaust manifolds, wastegate valve, inlet air humidifier, inlet air heater and more.

5. THE EFFECTS OF VARIOUS NOZZLE HOLE CONFIGURATIONS ON DIESEL ENGINE PERFORMANCE
Abstract : Any improvement that can be done with the diesel engine to reduce emissions and fuel consumption is of importance. The aim of the studies presented in this thesis was to determine whether changes in the nozzle geometry of the fuel injection systems used in diesel engines might improve their emissions and fuel consumption.
