Abstract
In order to investigate the air flow characteristics through poppet inlet valves, the static and dynamic flow coefficients were measured by varying through wide limits the angle-areas and the opening periods of the valves.
As a result, it was found that when the angle-area was fixed, a valve having a lower maximum valve lift always showed better flow characteristics under both static and dynamic conditions. Also, a parameter which satisfactorily correlated the static and dynamic flow coefficients was found.
