Abstract
An intake manifold for a multi-cylinder internal combustion engine of the type wherein blow-by gas and/or EGR gas is supplied to engine cylinders. The intake manifold comprises a plurality of branch runners each of which has a flange section fixedly secured to a cylinder head of the engine. A rib section integrally bridges the flange sections of the adjacent branch runners and is formed therein with a gas passage through which blow-by gas or EGR gas flows. The gas passage is communicated with the intake air passages of the adjacent branch runners so that the blow-by gas or EGR gas is uniformly distributed into the adjacent branch runners.
