Abstract
An intake system for a V-type engine comprises a surge tank, a common intake pipe upstream of the surge tank and a plurality of discrete intake pipes for connecting the respective cylinders in the cylinder banks of the V-type engine with the surge tank. Each of the discrete intake pipes for the cylinders in each cylinder bank comprises a U-shaped bight portion which projects from the side of the surge tank remote from the cylinder bank toward the other cylinder bank and is bent toward the cylinder bank, and a crossing portion which is connected between the corresponding intake port in the cylinder bank and the downstream end of the U-shaped bight portion and crosses the discrete intake pipes for the cylinders in the other cylinder bank below the surge tank.
