1. Characterization of the Combustion of Light Alcohols in CI Engines : Performance, Combustion Characteristics and Emissions
Sammanfattning : Alternative fuels for combustion engines are becoming increasingly popular as society is pushing to phase out fossil energy to reduce CO2 emissions. The compression ignition (CI) engine has a high overall efficiency which makes it a valuable option for the transport fleet, despite the well known NOx and soot pollutants it emits. LÄS MER
2. Characterization and Control of Multi-Cylinder Partially Premixed Combustion
Sammanfattning : In the last decade diesel combustion has developed in a new direction. Research has been carried out trying to prolong the ignition delay and enhance fuel/air premixing to avoid diffusion combustion as well as lowering the combustion temperature through use of EGR. One of these new combustion concepts is Partially Premixed Combustion (PPC). LÄS MER
3. Combustion Bowl Heat Transfer Analysis in Diesel and PPC Engines
Sammanfattning : This thesis concerns a numerical investigation on heat transfer in internal combustion engines, with the aim of increasing engine efficiency. The efficiency gains are to be extracted from reduced heat transfer losses, by increasing the knowledge on how the heat transfer process is affected by various hardware and operational parameters in the engine.
