2. 1. Optical Diagnostics of Gasoline Compression Ignition : HCCI-PPC-Diffusion Combustion

   Author : Marcus Lundgren; Förbränningsmotorer; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Optical engine; LTC; HCCI; PPC; Gasoline; High load;

   Abstract : Access to clean and affordable energy is one of the cornerstones of the world's society. Since the introduction of the internal combustion engine, diesel engines have become widely used for transportation in the commercial sector. READ MORE

4. 2. Evaluation of Gasoline PPC in a Multi-cylinder Engine : Capabilities & Challenges

   Author : Nikolaos Dimitrakopoulos; Förbränningsmotorer; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Partially Premixed Combustion PPC ; Light duty engine; Efficiency; Gasoline Compression Ignition; renewable gasoline;

   Abstract : Internal combustion engines have been the most used engine design when it comes to vehicle propulsion and transportation. But as the number of vehicles increase, new problems arise as well. READ MORE

5. 3. Supervisory control of complex propulsion subsystems

   Author : Dhinesh Vilwanathan Velmurugan; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Look-ahead control; engine control; exhaust after-treatment; supervisory control;

   Abstract : Modern gasoline and diesel combustion engines are equipped with several subsystems with the goal to reduce fuel consumption and pollutant exhaust emissions. Subsystem synergies could be harnessed using the supervisory control approach. Look-ahead information can be used to potentially optimise power-train control for real time implementation. READ MORE

6. 4. Bio-Inspired Urea Dosing and NOx Conversion : using a Biomimetic Effervescent Injector

   Author : Peter Larsson; Förbränningsmotorer; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bio-Inspired; Biomimetics; Bombardier Beetle; AdBlue; DEF; AUS-32; SCR; Exhaust After-treatment; Dosing; Nitrogen Oxides;

   Abstract : Transport of people and freight on-road have a big impact on the total energy use in the world. The majority of these transports is propelled with diesel engines and the reason is simply that the diesel engine is better than the gasoline engine due to lower fuel consumption. But the cost of this is the increase in dangerous nitrogen oxides (NOx). READ MORE

7. 5. Aging effects on commercial lean NOx trap catalysts

   Author : Jesus De Abreu Goes; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; aging; thermal degradation; sulfur poisoning; characterization; commercial lean NOx traps; NOx storage and reduction;

   Abstract : As a countermeasure to global warming, vehicles with low carbon emissions are being investigated by promoting lean-burn engines and high combustion efficiencies. However, one limitation to the increasing use of these engines is the need to develop corresponding catalytic systems for controlling the nitrogen oxide (NOx) emissions in their lean exhaust.
