2. 1. Alcohol Flexible Dual-Fuel Direct Injection Engine

   Author : Michael Saccullo; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fuel spray; Ethanol; Dual-fuel; Heavy duty engine; Diffusion combustion; Dual-direct injection; E85; Methanol;

   Abstract : Laws concerning emissions from HD internal combustion engines are becoming increasingly stringent in terms of local emissions and emissions concerning global warming such as lowering tailpipe CO2. New engine technologies are needed to satisfy these new requirements and to reduce fossil fuel dependency and increase renewable fuels in the transportation sector. READ MORE

4. 2. Transient Air to Fuel Ratio Response in a Fuel Injected S.I Engine

   Author : Göran Almkvist; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; dynamic; A F; model; transient; air to fuel; response; time constant; film; behavior; lambda; time-delay; fuel; mass; deposit factor;

   Abstract : Future emission standards make it necessary to focus on the conditions under which engine emissions are produced, especially before the catalyst light off. During practical driving conditions, such as those represented by the FTP 75 test cycle, the engine is operated very much under transient conditions regarding load and speed. READ MORE

5. 3. Characterization of the Homogeneous Charge Compression Ignition Combustion Process

   Author : Anders Hultqvist; Förbränningsmotorer; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; akustik; Motors and propulsion systems; Motorer; framdrivningssystem; Termisk teknik; termodynamik; Thermal engineering; applied thermodynamics; vakuumteknik; hydraulik; Maskinteknik; vibration and acoustic engineering; hydraulics; vacuum technology; ATAC; Mechanical engineering; MK; CAI; TS; MULDIC; PREDIC; HCCI; fuel tracer; combustion; injection; direct; port; engine; LDV; LIF; PLIF; vibrationer;

   Abstract : The main objective of this project was to characterize the HCCI combustion process. Central parts in the project were the progress of the HCCI combustion process, the influence of charge homogeneity on the combustion process and sources of UHC and CO emissions in HCCI combustion.

6. 4. Methanol Diesel Dual Fuel Direct Injection in a HD-CI Engine

   Author : Michael Saccullo; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Alcohol Fuels; Heavy Duty Engine; Dual Fuel; Combustion;

   Abstract : Laws concerning emissions from heavy duty (HD) internal combustion engines are becoming increasingly stringent. New engine technologies are needed to satisfy these new requirements and to reduce fossil fuel dependency. READ MORE

7. 5. Large-Eddy Simulation of Gasoline Fuel Spray Injection at Ultra-High Injection Pressures

   Author : Sandip Wadekar; 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; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LES; High pressure fuel injection; spray-wall interaction; spray-turbulence interaction; GDI engine; Spray modeling;

   Abstract : Gasoline direct injection is a state-of-the-art technique that reduces hydrocarbon and particulate emissions. However, further improvement is needed to meet current as well as future emission regulations. READ MORE
