Claims

[Scope of utility model registration request]

An intake guide plate 2 for guiding the intake air toward the outer side A is provided in the middle of the spiral intake port 1 of the engine E in an inclined shape where the leeward side approaches the outer side A, and as the rotational speed of the engine E increases, the inclined guide plate 2 gradually deviate to the inner side B,
In an intake outer guide device for a spiral-shaped intake port 1 of an engine configured to increase the intake cross-sectional area, a plurality of plate portions 3 and 3 are arranged such that an inclined guide plate 2 is stacked front and back.
It consists of..., and there is a ventilation part 4 in the middle of the front plate part 3.
The ventilation part 4 can be opened and closed by the rear plate part 3, and the rear plate part 3 elastically opens and closes according to changes in the intake negative pressure, and when the negative pressure is low, the ventilation part 4 can be opened and closed. □ An intake outer guide device for a spiral-shaped intake port of an engine, characterized in that it is configured to move forward toward the outer circumference side A and close, and to retreat toward the inner circumference side B and open when high negative pressure is present.
