    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; detailed-chemistry; surrogate fuel; homogeneous charge compression ignition; internal combustion engines; modeling; HCCI; gasoline; auto-ignition; combustion;

    Abstract : During the last decade an alternative to conventional internal combustion engines, i.e. spark-ignited and Diesel engines, has been under investigation by an ever-increasing number of research groups. READ MORE

  4. 22. 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.
