2. 1. 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

4. 2. Challenges and Advantages of Stratified Combustion in Gasoline Direct-Injected Engines

   Author : Anders Johansson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Particulate Mass; SGDI; Particulate Number; Direct-Injected; GDI; Particulate Sampling; Spray-Guided; Particulates; Stratified Charge; Gasoline; DI;

   Abstract : The modern world is based on an extensive transport network in which passenger vehicles play a major role. Although passenger vehicles have improved significantly in recent decades, they still contribute to the pollution of our environment and global warming. Consequently, new ways of reducing their emissions are needed. READ MORE

5. 3. Gasoline Engine HCCI Combustion - Extending the high load limit

   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NVO; stratified charge; gasoline engine; high load; knock.; HCCI; stoichiometric; CAI; ringing; SCCI;

   Abstract : There is an increasing global focus on reducing emissions of greenhouse gases.For the automotive industry this means reducing CO2 emissions of the vehiclesmanufactured, which is synonymous with reducing their fuel consumption oradapting them for using renewable fuels. READ MORE

6. 4. Particulate Formation in Gasoline Direct Injection Engines

   Author : Sreelekha Etikyala; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; PM; Volatileorganic compounds; Gasoline Direct Injection; Particulate Number; Alternate fuels;

   Abstract : Gasoline direct injection (GDI) engines are facing a great challenge because of the need to comply with increasingly stringent emission regulations while improving fuel economy. GDI engines are popularly known for their high fuel efficiency (by the standards of gasoline engines) and low emissions, enabling higher compression ratios and thus increased volumetric efficiency.
