1. Hollow cone gasoline/ethanol sprays under cold start conditions
Sammanfattning : To decrease the release of CO2 from fossil fuels into the atmosphere, within the transportation sector the efficiency of vehicles and their engines must be increased. Additionally renewable fuels may be used to further decrease our reliance on fossil fuels. LÄS MER
2. Injection and Combustion of Alternative Fuels in Spark Ignited Direct Injection Engines
Sammanfattning : Increasingly stringent vehicle emission legislation necessitates increasingly efficient combustion engines. The use of direct injection in spark ignited engines improves engine efficiency and reduces CO2 emissions. LÄS MER
3. Towards sustainable heavy-duty transportation : Combustion and emissions using renewable fuels in a compression ignition engine
Sammanfattning : Transportation should become sustainable and available to everyone. Currently, transportation accounts for approx. one sixth of greenhouse gas (GHG) emissions globally, and heavy-duty trucks are responsible for almost 30% of that. LÄS MER
4. Alcohol Flexible Dual-Fuel Direct Injection Engine
Sammanfattning : Laws concerning emissions from HD internal combustion engines are becoming increasingly stringent in terms of local emissions and emissions concerning global warming such as lowering tailpipe CO2. New engine technologies are needed to satisfy these new requirements and to reduce fossil fuel dependency and increase renewable fuels in the transportation sector. LÄS MER
5. Deactivation of commercial three-way catalysts: effect of the thermal ageing
Sammanfattning : This licentiate thesis is a summary of my study on thermal deactivated commercial threeway catalysts (TWCs). The experiments were performed using gasoline and a E85 fuelmixture of 85 vol.% ethanol and 15 vol.% gasoline. LÄS MER
