Intake apparatus for internal combustion engine

An intake apparatus for an internal combustion engine that includes a first bank and a second bank, the intake apparatus comprising:

• an intake pipe including a single fresh air intake pipe portion through which fresh air flows, two branching pipe portions for the first bank and the second bank, and a branching portion that connects the fresh air intake pipe portion to the two branching pipe portions;
• an EGR gas pipe connected to the branching portion and configured to draw EGR gas into the intake pipe;
• and
• a partition wall arranged at a periphery of an opening of the EGR gas pipe that opens in the intake pipe, wherein
• the partition wall defines an EGR gas accumulation chamber into which EGR gas flows and out of which EGR gas flows toward the first bank and the second bank, and
• the EGR gas accumulation chamber includes
• a first bank flow passage through which EGR gas flows out toward the first bank, and
• a second bank flow passage through which EGR gas flows out toward the second bank,
• wherein a first effective cross-sectional area of the first bank flow passage and a second effective cross-sectional area of the second bank flow passage are smaller than a flow passage cross-sectional area of the EGR gas pipe at the opening.
