BYPASS STRUCTURE OF AN INTAKE MANIFOLD SUITABLE FOR PREVENTING A DECREASE IN INTAKE EFFICIENCY

摘要

PURPOSE: A bypass structure of an intake manifold is provided to improve engine performance by improving the efficiency of an air intake and to reduce energy consumption required for driving a compressor.;CONSTITUTION: A bypass structure of an intake manifold comprises an intake manifold(100), a compressor(310), a bypass passage(140), and an air opening/closing member(200). The intake manifold includes a surge tank(110), a main passage(111), a first sub passage(120), and a second sub passage(130). The compressor is arranged between the first and second sub passages and makes compressed air flow into the surge tank. The bypass passage connects the first and second sub passages. The air opening/closing member allows or blocks the air inflow according to rotation.;COPYRIGHT KIPO 2013;[Reference numerals] (230) Motor
