<P>PROBLEM TO BE SOLVED: To provide an intake device of an engine capable of efficiently generating intake turbulence to a swirl direction. <P>SOLUTION: The intake device includes a first guide part 38 extended to form a spiral shape on at least either inner surface in a branch port 23, and a second guide part 39 formed in a spiral shape continuing to the first guide part 38 and extended to an inner surface of an intake port 22 before branching. Thus, intake turbulence to the swirl direction can be efficiently generated. That is, for example, even in the intake port 22 in which a port length of the branch port 23 is formed to be short, lengths of the guide parts for generating a swirl component in the intake can be sufficiently secured so as to efficiently generate the swirl component in the intake. <P>COPYRIGHT: (C)2013,JPO&INPIT |
