  4. 2. Lagrangian CFD Modeling of Impinging Diesel Sprays for DI HCCI

    Author : Per Strålin; Hans-Erik Ångström; Christian Kreuger; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HCCI; Diesel; early direct-injection; impinging nozzle; CFD; Lagrangian modeling; collision models; O’Rourke; Engineering mechanics; Teknisk mekanik;

    Abstract : The homogeneous charge compression ignition (HCCI) concept has been acknowledged as a potential combustion concept for engines, due to low NOx and soot emissions and high efficiency, especially at part-load. Early direct-injection (DI) during the compression stroke is an option when Diesel fuel is used in HCCI. READ MORE

  5. 3. Simulation of Combustion and Mixture Formation for Gasoline Direct Injection Engine Application
