22. Lagrangian CFD Modeling of Impinging Diesel Sprays for DI HCCI
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
