摘要：

The purpose of this study is to find new evaluation indices for the bulk motion of in-cylinder flow instead of the current swirl or the tumble coefficient and ratio using a steady flow test rig on intake port systems. To do this, port flow rig tests were conducted on the double-overhead cam head. Finally, the angular flow coefficient (N-A), the inclination angle (gamma), the angular flow parameter (P-A) and the flow angle (phi) were introduced as new evaluation indices for the bulk motion of in-cylinder flow.
