Investigation into air flow characteristics through inlet valve of directed ports
- Tianjin Univ. (China)
The velocity and turbulence intensity profiles at exit of intake valve from typical SI engine intake ports (horizontal and sloping directed ports) were measured by hot wire anemometry (HWA) in a steady flow rig. The characteristics of velocity and turbulence intensity distribution under different valve lifts and at distances along valve axis were analysed and compared between above two intake ports. Results showed that velocity and turbulence intensity profiles are strongly dependent on intake port form, valve lift and surrounding geometry. They vary not only around the valve head periphery but also along the valve axis. 9 refs., 14 figs.
