6. 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.

7. Large eddy simulation using linear eddy sub-grid mixing modeling
Sammanfattning : As emissions regulations are getting stricter and efficiency requirements of engines are increasing, different concepts to improve combustion are beinginvestigated. For example lean stratified premixed combustion, homogeneous charge compression ignition(HCCI), use of more exhaust gas recirculation (EGR) to reduce NOx etc. LÄS MER
8. A Representative Interactive Linear Eddy Model
Sammanfattning : To further improve the efficiency and emissions profiles ofinternal combustion engines, many new combustion conceptsare currently being investigated. Examples includehomogeneous charge compression ignition (HCCI), stratifiedcharge compression ignition (SCCI), lean stratified premixedcombustion, and the use of high levels of exhaust gasrecirculation (EGR) in diesel engines.
