摘要:
An intake device for an internal combustion engine comprises an outwardly extending flange attached to a throttle barrel and a saucer-like member attached to the flange to form a ring-shaped intake passage therebetween. An air flow meter duct is arranged with the outlet disposed at the portion of the ring-shaped intake passage having the smallest cross-sectional area. The air flow velocity within the duct is equal to the velocity at this smallest cross-sectional area section, thus permitting measurement thereof by measuring the flow through the meter and scaling appropriately by the ratio of meter flow passage to intake passage cross-sectional areas.
