Abstract
An EGR gas distributor for distributing EGR gas to branch pipes of an intake manifold includes a plurality of gas distribution passages arranged side by side for the branch pipes, a gas inflow passage and a gas chamber to deliver the EGR gas to each of the gas distribution passages. The gas inflow passage includes two, first and second, gas passage parts branched in a single stage. When the EGR gas distributor is mounted on the intake manifold, a passage cross-section of each gas passage part perpendicular to a central axis has an uppermost vertex and a lowermost vertex. The passage cross-sections of the gas passage parts are sized such that their lengths in a vertical direction are gradually longer from an upstream side of the first gas passage part to a downstream side of the second gas passage part.
