Abstract
Enhanced combustibility by increasing the difference in intake gas velocity between a low flow velocity region and first and second high flow velocity regions in an intake port. An intake port of an internal combustion engine has an intake flow control port portion provided with first and second projecting portions. In the passage cross section of the intake flow control port portion, there are provided a low flow velocity region, and first and second high flow velocity regions formed on either side of and across the low flow velocity region and the first and second projecting portions wherein the maximum flow velocity of intake gas is comparatively larger than that in the low flow velocity region. The intake gas reaches intake ports with a flow velocity distribution having the relationship of the magnitudes of flow velocities in the low flow velocity region and first and second high flow velocity regions.
