17. Optical Diagnostics Applied to Internal Combustion Engines: Catalysis, Sprays and Combustion
Abstract : Gasoline direct injection with spray-guided charge formation is one of the most promising concepts to reduce fuel consumption and CO2 emissions of spark ignited engines. The advantages with the system are owing to un-throttled operation and stratification of the injected fuel resulting in a globally lean combustion. READ MORE

18. Spark Ignition Combustion of Direct Injected Alternative Fuels
Abstract : Several technologies and modifications exist to increase the fuel efficiency of passenger vehicles in general and spark ignition engines in particular. Combining a spark ignition engine with an electric drive system in hybrid powertrain and thermodynamic cycle improvements are two such approaches with the potential to greatly reduce fuel consumption.

20. In-Nozzle Flow, Spray and Combustion Investigations of Two-Stroke Marine Diesel Engine Fuel Injectors
Abstract : This thesis focuses on the experimental studies of the cavitating in-nozzle flow of large two-stroke marine Diesel engine fuel injector nozzles and how it affects the spray morphology and combustion behaviour. To further increase the efficiency of large two-stroke marine Diesel engines, a better understanding of the fuel spray atomization process is necessary. READ MORE
