Abstract

An air intake apparatus for an internal combustion engine is an apparatus introducing intake air into a combustion chamber (40), and includes an intake manifold (200) attached to a cylinder head (30), and a cartridge (300) fitted into the intake manifold (200). The cartridge (300) includes a tube-like main body (310) forming an air intake channel (50), a partition (320) provided on the main body (310) to separate the air intake channel (50) into first and second passages (51, 52), and an air intake control valve (330) capable of reducing a channel cross sectional area of at least one of the first and second passages (51, 52) separated by the partition (320).

Description

technical field [0001] The invention relates to an intake device for an internal combustion engine, in particular to an intake device with an intake control valve for an internal combustion engine. Background technique [0002] In general, an intake device for an internal combustion engine having an intake control valve is known. [0003] For example, Japanese Patent Publication No. 2003-206761 (Patent Document 1) discloses an air supply device capable of providing a variable intake flow rate in which a valve element is provided in each cylinder of an inline four-cylinder internal combustion engine. [0004] Furthermore, the specification of German Patent Publication No. 10108729 (Patent Document 2) discloses an internal combustion engine having a partition inserted into a cylinder head. [0005] Furthermore, the specification of US Patent No. 5273014 (Patent Document 3) discloses an insertion member inserted into an intake passage of an internal combustion engine, which ha...
