2. 1. Learning control for flex-fuel CI engine and fuel cell

   Author : Xiufei Li; Förbränningsmotorer; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Flex-fuel CI Engine; Fuel Cell; Model Predictive Control; Learning Control; Adaptive Control; Gas System Model; Ignition Delay Model; Data-based Modeling; Gaussian process;

   Abstract : This thesis investigated the modeling and control problems in the context of the flex-fuel compression-ignition (CI) engine and fuel cell, which shows great potential in the transition from fossil fuel to renewable energy sources.The modeling parts included the flex-fuel engine combustion process and intake system, and the system scale fuel cell model.

4. 2. Transient Spray Mode Fuel Injection

   Author : Lokesh Mopuri; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; clogged nozzle; non-evaporative and reactive spray; thimble structure; Spray characteristics;

   Abstract : This research examines the pivotal role of transient fuel spray in internal combustion engines, primarily focusing on their influence on dual-fuel (DF) engines. In the case of dual-fuel (DF) engines functioning in a gas mode, the controlling of the primary fuel’s ignition is usually managed through the direct injection of liquid pilot fuel. READ MORE

5. 3. Combustion characteristics of some alternative fuels in ICE: : a detailed numerical study

   Author : Siyuan Hu; Strömningsteknik; []
   Keywords : Combustion; duel fuel; methane; hydrogen; nheptane; methanol; DNS; simulation; openFoam; mixture-averaged; RCCI; ignition wave;

   Abstract : Two major fuels commonly used in compression ignition (CI) and spark ignition (SI) enginesare diesel and gasoline. The reserve of diesel and gasoline is limited, however the combustion ofthese fuels giving rise to air pollution. READ MORE

6. 4. High Repetition Rate Laser Diagnostics for Combustion Applications

   Author : Johan Sjöholm; Förbränningsfysik; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; spray; diesel; optical engine; simultaneous; laser-induced fluorescence; fuel tracer; SLIPI; Raman; LII; laser diagnostic; combustion; high repetition rate; high-speed; PLIF; multi-YAG; LIF; fuel jet; Fysicumarkivet A:2012:Sjöholm;

   Abstract : High repetition rate laser diagnostics has proven to be a useful tool for studying combustion phenomena. Laser techniques are, in general, relatively non-intrusive and have the potential to measure specific species at very low concentrations and with extremely high temporal resolution. READ MORE

7. 5. Experimental and Modeling Studies of Sulfur-Based Reactions in Oxy-Fuel Combustion

   Author : Daniel Fleig; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SO3; acid dew-point; coal combustion; oxy-fuel; sulfur; flue gas recycle; corrosion; Carbon capture and storage; H2SO4; SO2;

   Abstract : Oxy-fuel combustion is a technology for CO2 capture that is suitable for large-scale, coal-fired power plants. In this system, the combustion air is replaced by a mixture of O2 and recycled flue gases, so as to enrich for CO2 in the flue gas. READ MORE
