Abstract

A numerical analysis of the flow and mixing of rich mixture and air inducted into the cylinder through each of the two intake ports of a stratified charge engine have been carried out. Numerical calculations were performed by finite volume method for three types of the intake port configurations: inverse V type, parallel type and V type and two types of valve timing; conventional and late closing (Miller cycle). Velocity field, turbulent kinetic energy and distribution of mixture concentration in the cylinder were examined. 3 refs., 10 figs.
