Abstract
An internal combustion engine intake device is configured to improve the uniformity with which purge gas or other introduced gas is distributed to the cylinders of an engine. The intake device basically has a throttle chamber, an intake air collector, an air induction pipe, a partitioning part and a gas introducing pipe. The air induction pipe is provided between the throttle valve and the intake air collector. The partitioning part divides the space inside the air induction pipe into first and second air induction spaces. The gas introducing pipe is configured and arranged to introduce purge gas into the space inside the air induction pipe at a position between the throttle valve and the partitioning part. In one embodiment, the partitioning part is configured such that an upstream portion thereof is slanted with respect to a rotary shaft of the throttle valve.
