PURPOSE: A surge tank of a vehicle engine is provided to prevent noise caused by contacting flowing waves to a wall surface of a tank, and to improve the NVH(noise, vibration, and harshness) of an engine by mounting poles at the inner portion of the surge tank, thereby compensating the introduced flowing waves. CONSTITUTION: In a surge tank of a vehicle engine, poles(12) are disposed vertically with respect to ports(11) at the inner portion of a surge tank(10) for generating interference with relation to flowing waves sucked through the port. The poles are formed in cylinder shape. A number of the poles are the same as the number of the ports. The poles interfere with the flowing waves drawn from the ports by fixing both end of the poles at the zenith and bottom of the surge tank.
