2. 1. Optical Diagnostics for Engine Efficiency in Gasoline Compression Ignition

   Author : Miao Zhang; Förbränningsmotorer; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; PPC; Optical engine; Engine Eciency; Multiple-injection strategies; Thermodynamic analysis;

   Abstract : The internal combustion engine has played a significant role in a vast number of applications from small cars to giant tankers, setting people free from geographical barriers and heavy labor. However, it has also generated many tons of harmful emissions and CO2that damage to humans and the environment. READ MORE

4. 2. Investigation of PPC in an Optical Engine : With focus on Fuel Distribution and Combustion Characterization

   Author : Sara Lönn; Förbränningsmotorer; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Optical engine; PPC; Fuel distribution; Methanol;

   Abstract : The global society is dependent on transportation to function and a big part of these transports are driven by an internal combustion engine. Heavy-duty vehicles utilizes conventional diesel combustion is a combustion concept where the fuel is often ignited during the injection event and while it gives a high combustion efficiency, the combustion mode is also characterized by high emission of NOx and soot.

5. 3. Reducing Diesel Engine Emissions - An Experimental Investigation

   Author : Arjan Helmantel; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Optical methods; Soot; Diesel; Emissions; HCCI;

   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

6. 4. Optical Diagnostics of Soot in Combusting Sprays

   Author : Raul Lima Ochoterena; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Optical diagnostics.; Laser Induced Incandescence LII ; Elastic Light Scattering ELS ; Soot formation; Flame temperature; Spray combustion; Light Extinction LE ;

   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.
