吸気装置。 In the case where the intake pipe leading to the intake port is divided into two passages and a control valve is provided in one of the passages, the passage in which the control valve is installed is tapered so that the passage cross-sectional area gradually decreases toward the intake port. The other passage has the same passage cross-sectional area with a size that maintains the required flow rate in the low-speed operation region, and the control valve has a configuration in which the pipes of both passages are sized to maintain the required flow rate in the low-speed operation region. A variable intake device characterized in that the opening degree is controlled so that the valve opening degree takes into account road resistance and overall flow velocity.
