Abstract

An intake system includes two surge tanks for cylinders in first and second cylinder banks of a V-type internal combustion engine which are arranged side by side over one of the first and second cylinder banks in the lengthwise direction of its associated engine and, are preferably formed as one unit and includes intake passages arranged in series in the lengthwise direction, each intake pipe connecting the surge tank with each of the cylinders in the first and second cylinder banks. The outermost intake passages disposed at the opposite ends of the surge tanks extend outward of the surge tanks in the opposite directions and are bent back into a space between the first and second cylinder banks. The remaining intake passages for the cylinders in the first cylinder bank are of C-shaped passage and the remaining intake passages for the cylinders in the second cylinder bank cross inside the C-shaped intake pipes in the space.
