Abstract
An intake manifold for a V-type multi-cylinder internal combustion engine provided with two banks each including a cylinder head. The intake mainfold comprises lower and upper intake air collectors which lie one upon another and located above one of the two banks. The intake air collectors are supplied with intake air from an air filter. A first group of branch runners are provided to connect the lower intake air collector with the cylinder head of one bank, while a second group of branch runners are provided to connect the upper intake air collector with the cylinder head of the other bank. The upper end section (connected to the lower intake air collector) of each of the first group of branch runners and the upper end section (connected to the upper intake air collector) of each of the second group of branch runners lie one upon another thereby to form a space required for an ignition device and installation operation therefor, between the adjacent branch runners in the cylinder head logitudinal direction.
