  4. 17. Numerical Modelling of Fuel Injection and Stratified Turbulent Combustion in a Direct-Injection Spark-Ignition Engine Using an Open Source Code

    Author : Chen Huang; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hollow-cone spray; KHRT; liquid penetration; CFD; OpenFOAM; Flame Speed Closure FSC ; ignition delay; SMD; gasoline surrogate; laminar flame speed; presumed PDF; Spray-Guided Gasoline Direct Injection engine; chemical mechanism; modelling; premixed stratified turbulent combustion;

    Abstract : Stringent regulations on the emission of pollutants, especially carbon dioxide (CO2), necessitate the development of advanced combustion technologies. Gasoline direct injection (GDI) into the combustion chamber of a Spark Ignition (SI) engine is a combustion strategy that is widely recognized as having the potential to improve fuel efficiency of internal combustion engines for passenger cars.

  5. 18. The HCCI Fuel Number - Measuring and Describing Auto-ignition for HCCI Combustion Engines

    Author : Ida Truedsson; Förbränningsmotorer; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fuel; Combustion Engines; HCCI; Auto-ignition;

    Abstract : HCCI is an advanced combustion concept, using premixed fuel and air with a diluted charge. This is thermodynamically favorable, leading to high efficiency and therefore lower CO2 emissions. READ MORE

  6. 19. Development of Laser-Induced Fluorescence for Precombustion Diagnostics in Spark-Ignition Engines

    Author : Hans Neij; Förbränningsfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; DME; fuel tracer; Laser-induced fluorescence; 3-pentanone; acetone; residual gas; dimethyl ether; water vapor; Fysicumarkivet A:1998:Neij; Fysik; Physics; ion current;

    Abstract : Motivated by a desire to understand and optimize combustion in spark-ignition (SI) engines, laser techniques have been developed for measurement of fuel and residual gas, respectively, in the precombustion mixture of an operating SI engine. The primary objective was to obtain two-dimensional, quantitative data in the vicinity of the spark gap at the time of ignition. READ MORE

  7. 20. Computer Modeling of HCCI Combustion
