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 (NA), the inclination angle (γ) the angular flow parameter (PA) and the flow angle (φ) were introduced as new evaluation indices for the bulk motion of in-cylinder flow.
