Abstract

The invention provides the intake device of an internal combustion engine, which comprises a plurality of air intake passages used for introducing air from an air filter into a throttle body. A connection supporting member (52) supported in an air cleaning box (44) comprises a first downstream air inlet passage part (61) and a second downstream air inlet passage part (62) used for communicating the flow outlet of a high-speed air intake passage (53) with the flow outlet of a low-speed air intake passage (54), and a confluence part used for converging the first downstream air inlet passage part (61) with the second downstream air inlet passage part (62). Through the connection supporting member (52), the high-speed air intake passage (53) and the low-speed air intake passage (54) are supported within an air cleaner (22).

Description

technical field [0001] The present invention relates to an air intake device for an internal combustion engine for feeding air introduced by an air cleaner into the internal combustion engine. Background technique [0002] An intake device for an internal combustion engine is known in which a low-speed intake passage connected to an air cleaner and a high-speed intake passage merge upstream of a throttle body (see Patent Document 1). [0003] In the air intake device disclosed in Patent Document 1, the projections of the low-speed intake passage and the high-speed intake passage on the projection plane in the axial direction of the pipe with the throttle valve are approximately the same, and the low-speed intake passage passes through and is formed in the high-speed intake passage. The openings on the side walls of the gas path are connected to merge with the high-speed air intake path. Each intake path is connected to an opening formed in the air cleaner. [0004] In this...
