Abstract:
To provide an intake control device which can supply a prescribed quantity of bypass intake air even if a capacity of a bypass flow passage is relatively small.SOLUTION: An intake control device 1 controls an intake amount of an internal combustion engine 2, and comprises a plurality of intake pipes 4 in which intake air introduced into the internal combustion engine 2 passes, valve bodies 5 arranged at intake pipes 4, respectively, and adjusting intake amounts of the intake pipes 4, and cross bypass passages 6 of the same number as that of the intake pipes 4. Each of the cross bypass passages 6 has an upstream-side opening part 7 which is opened at an inner wall face of one intake pipe 4 at an upstream side with respect to the valve body 5, and a downstream-side opening part 8 which is opened at an inner wall face of the other intake pipe 4 at a downstream side with respect to the valve body 5. The downstream-side opening part 8 exists one by one at each intake pipe 4.SELECTED DRAWING: Figure 1
