| Abstract: | This paper presents a KIVA 3 code based numerical model for three dimensional transient intake flow in the intake port valve cylinder system of internal combustion engine using body fitted technique, which can be used in numerical study on internal combustion engine with vertical and inclined valves, and has higher calculation precision. A numerical simulation (on the intake process of a two valve engine with a semi sphere combustion chamber and a radial intake port) is provided for analysis of the velocity field and pressure field of different plane at different crank angles. The results revealed the formation of the tumble motion, the evolution of flow field parameters and the variation of tumble ratios as important information for the design of engine intake system. |
