2. 6. A simulation tool for optimising combustion engine cylinder liner surface texture

   Author : Andrew Spencer; Martin Priest; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Maskinelement; Machine Elements;

   Abstract : Fuel efficiency is one of the most important areas of automotive vehicle research and development today, with rising fuel costs, energy security and environmental concerns being at the forefront of customers and legislators minds. Heavy Duty Diesel Engines (HDDE) are the primary source of mechanical power generation in today’s trucks and buses and this is likely to continue for the foreseeable future. READ MORE

4. 7. Deactivation mechanisms influencing the performance and durability of exhaust aftertreatment systems

   Author : Jesus De Abreu Goes; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thermal degradation; Gasoline particulate filters; Lean NOx traps; Sulfur poisoning.;

   Abstract : As countermeasure to air pollution and global warming, more stringent environmental policy measures will probably come into force with the future emission standards, which will require important developments for gasoline and diesel vehicles to meet the emerging criteria. Efficient catalytic formulations and advanced strategies for exhaust aftertreatment systems will be therefore demanded to provide both high catalytic activity and stability, minimizing the environmental impact by automobiles.
