Abstract

A variable intake system for a vehicle which controls air flow amount flowing into each combustion chamber according to rotation speed of an engine may include an air cleaner main body connected with a main duct and an auxiliary duct through which air flows, a valve housing which may be disposed within the air cleaner main body and communicated with the auxiliary duct, a valve assembly disposed to the valve housing and controlling an opening amount of the valve housing, an actuator mounted to the valve housing and coupled to the valve assembly to operate the valve assembly, and a controller controlling operation of the actuator, wherein the actuator may be a linear motor including a motor shaft which realizes linear motion according to supplying current to a coil of the actuator.

Description

[0001] Cross References to Related Applications [0002] This application claims priority from Korean Patent Application No. 10-2011-0117204 filed with the Korean Intellectual Property Office on Nov. 10, 2011, the entire contents of which are hereby incorporated by reference for all purposes. technical field [0003] The invention relates to a variable air intake system for a vehicle. More particularly, the present invention relates to a variable intake system for a vehicle that can control the flow rate of air flowing into a combustion chamber according to the rotational speed of an engine. Background technique [0004] Generally, the air intake system set to the vehicle engine purifies the air flowing through the intake duct by means of filter elements in the air filter box, and provides the engine with a plurality of intake ducts for compensating for high speed and Air volume required for high loads. [0005] In the conventional art of the variable intake system, the in...
