<p>A structure for increasing suction efficiency of a surge tank is provided to enhance performance of the surge tank by forming vacuum at an auxiliary vacuum tank and removing a boundary layer in a zip tube by using negative pressure of the sub-vacuum tank. A structure for increasing suction efficiency of a surge tank comprises a suction hole(11) formed in a zip tube(10a) in which a boundary layer is to be formed. A auxiliary vacuum tank(13) is additionally installed at the surge tank(10). A first connection hose(14) connects the suction hole(11) to the auxiliary vacuum tank(13). A second connection hose(15) connects the auxiliary vacuum tank(13) to the surge tank(10). A first valve(16) is mounted at the first connection hose(14). A second valve(16) is mounted at the second connection hose(15). The first valve(16) or the second valve(16) is a check valve.</p> |
