Abstract
Plural cylinders are divided into cylinder groups consisting of the cylinders each having an equal inspiration stroke. The cylinder groups are so disposed as to allow their inspiration strokes to be apart from each other in a direction parallel to a crank axis in which a crankshaft extends. On its side surface, the cylinder head has an opening for an intake port which is communicated with an individual intake passage. Each of plural individual intake passage is extended from the respective cylinders for each cylinder group in the direction extending or elongated over the cylinder head and merged together at that location into a merged intake passage. The merged intake passage is extended toward the intermediate position between the two cylinder groups and thereafter curved, followed by extending toward the side of one side surface of the cylinder head.
