INTAKE DEVICE IN INTERNAL COMBUSTION ENGINE

摘要

PROBLEM TO BE SOLVED: To suppress the deflection vibration of each intake line of an intake device without causing increase of weight and increase of a cost, in the intake device which is formed by connecting pipe-made intake line from each air cylinder to a surge tank arranged on the side of a multi-air cylinder internal combustion engine. SOLUTION: A manifold 13 in which respective intake lines 5, 6, 7 are mutually tightly stuck, is arranged in a part in the middle of the intake lines 5, 6, 7, and the intake lines 5, 6, 7 are mutually connected in this manifold 13 by welding 14 or brazing.
