Popis: The potential of gasoline direct-injection (GDI) engines for significantly enhanced fuel economy, transient response and cold-start hydrocarbon emission levels has led to a large number of research and development projects that have the goal of understanding, developing and optimizing such engine system. This study deals with the numerical analysis on the thermo-fluid dynamic phenomenon in cylinder of the GDI engine. The analysis is restricted to a period from the compression to the expansion stroke in which include gasoline injection, mixing with air and combustion phenomena. In this study, the combustion process is focused adopting the Weller 3 equation model for the flame propagation in stratified premixed gases.
