Patent ID: 10612498

Abstract:
There is provided an intake manifold of a multicylinder engine capable of facilitating homogenization of concentration distribution of EGR gas in intake air and distribution of EGR gas into respective cylinders. The intake manifold is configured such that an EGR gas guide portion is provided in an intake air introducing sleeve portion, the EGR gas guide portion includes an upstream EGR gas release port and a downstream EGR gas release port, the upstream EGR gas release port is provided on a side of a passage outlet of an EGR gas introducing passage, the downstream EGR gas release port is provided on an opposite side of a central portion of the intake air introducing sleeve portion from the upstream EGR gas release port, and the EGR gas introduced from the passage outlet of the EGR gas introducing passage into the intake air introducing sleeve portion is released from both of the upstream EGR gas release port and the downstream EGR gas release port into intake air passing through the central portion of the intake air introducing sleeve portion.
