1. Torque based combustion property estimation and control for diesel engines
Sammanfattning : Modern diesel engines are becoming increasingly complex as a result of demands on the reduction of both fuel consumption and emissions. This escalating complexity not only applies to the engine itself, but also to its control system. LÄS MER
2. Optical Diagnostics Applied to Internal Combustion Engines: Catalysis, Sprays and Combustion
Sammanfattning : 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. LÄS MER
3. Computer Modeling of HCCI Combustion
Sammanfattning : During the last decade an alternative to conventional internal combustion engines, i.e. spark-ignited and Diesel engines, has been under investigation by an ever-increasing number of research groups. LÄS MER
4. On Alternative Fuels for Internal Combustion Engines : A study of biodiesel, gaseous methane and methanol
Sammanfattning : This thesis covers some of the environmental impacts of internalcombustion engines running on alternative fuels. The focus of thestudies conveyed is the reduction of greenhouse gases and particleemissions, as these two factors are of great importance for the pathsthat road transportation is facing. LÄS MER
5. Development and application of laser diagnostics - from laboratory devices towards practical combustion engines
Sammanfattning : For many decades, research work on combustion has been focused on improving combustion efficiency and reducing harmful emissions. Laser diagnostics is one of the best ways to investigate the combustion process and emission formation as it is non-intrusive and it has high spatiotemporal resolution. LÄS MER
