<P>PROBLEM TO BE SOLVED: To improve the supply responsiveness of an air amount necessary for an internal combustion engine by efficiently supplying air in a resonance chamber to a surge tank side in an intake manifold for the internal combustion engine. <P>SOLUTION: The intake manifold 10 comprises: a plurality of first to fourth branch pipes 12, 14, 16 and 18; a surge tank 20 to which ends of the first to fourth branch pipes 12, 14, 16 and 18 are connected, respectively; a suction connecting part 22 arranged at one end of the surge tank 20 along the longitudinal direction of the tank; the resonance chamber 24 arranged in parallel with the surge tank 20; and a communication passage 36 which makes the surge tank 20 and the resonance chamber 24 communicate with each other. Then, an opening 36b of the communication passage 36 is connected to a first resonance room 30 which is arranged in the center among a plurality of resonance rooms 30, 32a, 32b, 34a and 34b which constitute the resonance chamber 24. <P>COPYRIGHT: (C)2013,JPO&INPIT |
