6. Reducing Diesel Engine Emissions - An Experimental Investigation
Abstract : In the recent past, the Diesel engine has been improved considerably in the areas ofperformance, fuel efficiency and exhaust emissions. In Europe, these improvements haveresulted in a strong increase in the sales of passenger cars equipped with a Diesel engine. READ MORE

7. Optical Diagnostics of Soot in Combusting Sprays
Abstract : Optical diagnostics in combusting diesel sprays were carried out in the Chalmers High Pressure, High Temperature (HP/HT) spray rig at conditions similar to those in an internal combustion engine, reaching up to 100 bar and 630 ◦ C. Spray development studies and combustion characterisation were done by high speed shadowgraphs that were digitally processed to measure the start of combustion, break-up, droplets and vapour penetration.

8. High Repetition Rate Laser Diagnostics for Combustion Applications
Abstract : High repetition rate laser diagnostics has proven to be a useful tool for studying combustion phenomena. Laser techniques are, in general, relatively non-intrusive and have the potential to measure specific species at very low concentrations and with extremely high temporal resolution. READ MORE

9. Processes in Optical Diesel Engines - Emissions Formation and Heat Release
Abstract : 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. READ MORE

10. Engine Knock: Characteristics and Mechanisms
Abstract : Knock in SI engines limits both power density and fuel conversion efficiency. The main mechanisms with the potential to generate the cylinder pressure fluctuations generally observed during knocking combustion are discussed. It is reasoned that some mechanisms of flame acceleration can further amplify a shock wave generated by autoignition. READ MORE
