摘要: An intake system for an internal combustion engine comprises an intake manifold and a surge tank member connected together to form a plurality of long bowed first discrete intake passages each leading to one of the cylinders and a volume chamber disposed on the upstream ends of the first discrete intake passages. The intake manifold is further provided with a plurality of second discrete intake passages each of which branches off from one of the first discrete intake passages to extend on the inner side of the same and is shorter than the first discrete intake passages, and with a communicating passage for interconnecting the second discrete intake passages. A valve is provided in each second discrete intake passage to open and close the second discrete intake passage according to the operating condition of the engine. A part of the wall defining the communicating passage is formed by a plate member sandwiched between the intake manifold and the surge tank member.
