摘要：Plural cylinders are divided into cylinder groups consisting of the cylinders eachhaving an equal inspiration stroke. The cylinder groups are so disposed as to allow theirinspiration strokes to be apart from each other in a direction parallel to a crank axis inwhich a crankshaft extends. On its side surface, the cylinder head has an opening for anintake port which is communicated with an individual intake passage. Each of pluralindividual intake passage is extended from the respective cylinders for each cylindergroup in the direction extending or elongated over the cylinder head and mergedtogether at that location into a merged intake passage. The merged intake passage isextended toward the intermediate position between the two cylinder groups andthereafter curved, followed by extending toward the side of one side surface of thecylinder head.
