INTAKE MANIFOLD FOR REDUCING RUMBLE NOISE

PURPOSE: An intake manifold for reducing a rumble noise is provided to change the forming position of manifolds connected to a surge tank so as to reduce the rumble noise generated because the distance from an air outlet of a throttle body to each manifold is different from each other. CONSTITUTION: In an intake manifold for reducing a rumble noise, a barrel type surge tank(31) is communicated with a side of a throttle body(32). A first and a fourth manifold(41,44) are formed so that the distance(L1) from the outlet(33) of the throttle body to the position for connecting the first manifold can be the same as the distance(L4) from the outlet of the throttle body to the position for connecting the fourth manifold. A second and a third manifold(42,43) are formed so that the distance(L2) from the outlet of the throttle body to the position for connecting the second manifold can be the same as the distance(L3) from the outlet of the throttle body to the position for connecting the third manifold.
