Abstract
An intake system for a V-type engine having a plurality of cylinders disposed in each of left and right cylinder banks has a central surge tank which is disposed above the space between the left and right cylinder banks and communicates with the atmosphere through a common intake passage, and left and right surge tanks which are respectively disposed above the left and right cylinder banks. Communicating passages connect the central surge tank with the left and right surge tanks, and discrete intake passages communicate the left and right surge tanks with the cylinders. At least one of the communicating passages on each side of the central surge tank is disposed between the discrete intake passages on the side of the central surge tank.
