Abstract
An intake pipe for an internal combustion engine has an intake assembly to which the air supplied from an air cleaner flows in accordance with the opening of a throttle valve, and independent intake pipes receive the air in the intake assembly and distribute the air into each cylinder of the internal combustion engine. The intake passage between the air cleaner and the throttle valve assembly is arranged next to and separated by a partition wall from at least one of a negative pressure part of the intake passage downstream of the throttle vale, the intake assembly provided in the negative pressure part and the independent intake pipes, whereby two independent intake spaces are formed on either side of the partition wall.
