1. Simulations of compressible flows associatedwith internal combustion engines
Sammanfattning : Vehicles with internal combustion (IC) engines fueled by hydrocarbon compoundshave been used for more than 100 years for ground transportation.During these years and in particular the last decade, the environmental aspectsof IC engines have become a major political and research topic.

2. Development of catalysts for natural gas-fired gas turbine combustors
Sammanfattning : Due to continuously stricter regulations regarding emissions from power generation processes, further development of existing gas turbine combustors is essential. A promising alternative to conventional flame combustion in gas turbines is catalytic combustion, which can result in ultralow emission levels of NOx, CO and unburned hydrocarbons. LÄS MER
3. Computation and Analysis of EGR Mixing in Internal Combustion Engine Manifolds
Sammanfattning : This thesis deals with turbulent mixing processes occurring in internal combustion engines, when applying exhaust gas recirculation (EGR). EGR is a very efficient way to reduce emissions of nitrogen oxides (NOx) in internal combustion engines. LÄS MER
4. Pulsating Combustion - Combustion Characteristics and Reduction of Emissions
Sammanfattning : In the search for high efficiency combustion systems pulsating combustion has been identified as one of the technologies that potentially can meet the objectives of clean combustion and good fuel economy.Pulsating combustion offers low emissions of pollutants, high heat transfer and efficient combustion.

5. Modeling and Control of EGR on Marine Two-Stroke Diesel Engines
Sammanfattning : The international marine shipping industry is responsible for the transport of around 90% of the total world trade. Low-speed two-stroke diesel engines usually propel the largest trading ships. This engine type choice is mainly motivated by its high fuel efficiency and the capacity to burn cheap low-quality fuels.
