21. Development and Application of Laser Techniques for Studying Fuel Dynamics and NO Formation in Engines
Abstract : Development and application of some laser techniques for the study of engine combustion are presented. The investigations mainly cover two aspects: fuel dynamics and formation of NO. READ MORE

22. Spray-Wall Interaction of Diesel Sprays
Abstract : A promising combustion concept that aims at reducing emissions from DI Diesel engines is HCCI (Homogeneous Charge Compression Ignition). To achieve a combustible air/fuel mixture in such an engine one possible strategy is early fuel injection during the compression stroke, even though the in-cylinder conditions are different from those in conventional DI diesel engines.

23. Divided Exhaust Period on Heavy-Duty Diesel Engines
Abstract : Due to growing concerns regarding global energy security and environmental sustainability it is becoming increasingly important to increase the energy efficiency of the transport sector. The internal combustion engine will probably continue to be the main propulsion system for road transportation for many years to come. READ MORE

24. Alternative Combustion Strategies for Gasoline Engines
Abstract : Due to increasingly strict legislative demands and customer concerns regarding CO2emissions, there is a need to develop and implement new combustion strategies forgasoline (Otto) engines. In attempts to meet this need, most attention is focusing onthe low load/speed range where the classic spark ignition strategy (SI) has poorefficiency, mainly due to the throttling of the intake air causing pumping losses.

25. Crystallographic studies on porphyrin metallation by ferrochelatase
Abstract : Ferrochelatase catalyses the terminal step in heme biosynthesis by inserting a ferrous ion into protoporphyrin IX. The reaction mechanism has in this thesis been studied by mainly crystallographic methods. READ MORE
