VARIABLE ZIP TYPE INTAKE SYSTEM EQUIPPED VARIABLE INTAKE DEVICE OF SEPARATED BANK TYPE

摘要

A variable zip type intake air system including bank separable variable intake system is provided to obtain the maximum torque in the entire region spanned from the low speed to the high speed by making the length of runner short and the variable diameter of the zip. A variable zip type intake air system including bank separable variable intake system comprises a zip(10) of the tube type having the predetermined curvature to the longitudinal direction; a plenum chamber(20) in which the bank separable variable intake system is equipped between the bank divided with two; a plurality of runners(30) connected in the other end part of the plenum chamber; a blade(16) varying the diameter of the zip; a cam(17) for operating the blade; an actuator(19) for rotating the cam; and a diameter variableness apparatus(15) consisting of the reconstruction spring(18) for restoring blade and maintaining the contact of blade.
