Beschreibung
Zusammenfassung:	The EGR gas distributor is attached to an intake manifold to distribute EGR gas to each of branch pipes constituting the intake manifold. The EGR gas distributor includes a gas distribution part including a gas inlet port for EGR gas, a plurality of gas outlet ports connected to each corresponding branch pipe, and a gas passage that extends by branching off into a plurality of branch sections from the gas inlet port to each gas outlet port. The gas passage has a tournament branch shape that extends by stepwise branching off from the gas inlet port to each gas outlet port and is symmetric about the gas inlet port. The EGR gas distributor includes a heating part provided adjacent to the entire gas distribution part to heat the gas distribution part. The heating part is constituted of a hot-water passage part configured to allow hot water to flow therethrough.
