21. Processes in Optical Diesel Engines - Emissions Formation and Heat Release
Sammanfattning : This project deals with questions related to generic diesel combustion research and optically accessible engines are used to study the combustion process. Images of the combustion are analyzed together with in-cylinder pressure and exhaust gas emission measurements. LÄS MER
22. Large eddy simulation of dual-fuel combustion under ICE conditions
Sammanfattning : The present thesis aims at studying n-heptane/methanol dual-fuel combustion under internal combustion engine conditions and strives to improve the understanding of its ignition, combustion, and pollutant emission mechanisms. Large-eddy simulation (LES) coupled with Eulerian stochastic fields (ESF) approach is employed to simulate single/dual-fuel combustion in a constant-volume vessel to mimic the single/dual-fuel combustion in conventional/dual-fuel premixed engines.

23. A Study of Injector Aging Effects on the Spray and Combustion in a Diesel Engine
Sammanfattning : .... LÄS MER
24. Emission and Deposit Formation in Direct Injection Stratified Charge SI Engines
Sammanfattning : A promising approach to increase the efficiency of the spark ignition (SI) engine is to inject the fuel directly into the cylinder to form a stratified charge. There is a potential to reduce the fuel consumption at low speeds and loads by 20 - 25% compared with conventional SI engines with stoichiometric homogeneous charge. LÄS MER
25. Enrichment of biogenic and anthropogenic organic substances on sea spray aerosols
Sammanfattning : The world’s oceans are the source of one of the most abundant types of natural aerosols, namely sea spray aerosols (SSA). By scattering solar radiation, SSA play a significant role in controlling the Earth’s radiation budget, while they are also involved in the formation of clouds, acting as cloud condensation nuclei (CCN).
