Abstract

A variable intake manifold apparatus for an internal combustion engine, may include an inlet drawing in outside air and being connected to a main passage, first and second outlets branched from the main passage and fluid-connected to the inlet through the main passage and releasing the outside air drawn through the main passage through the first and second outlets, and a partition dividing the main passage and one of the first and second intake passages.

Description

[0001] Cross References to Related Applications [0002] This application claims priority from Korean Patent Application No. 10-2012-0147808 filed on December 17, 2012, the entire contents of which are hereby incorporated by reference for all purposes. technical field [0003] The present invention relates to a variable intake manifold for an internal combustion engine and a variable intake device using the variable intake manifold, more particularly to such a variable intake manifold for an internal combustion engine and a variable intake device, which enhances the tumble and swirl of the intake air. Background technique [0004] Typically, combustion chambers are formed in internal combustion engines for direct injection of fuel by coupling a cylinder head to a cylinder block in which a piston is configured to reciprocate to compress or expand the combustion chamber and change its volume. [0005] An intake port for introducing air into the combustion chamber and an exhau...
