とする４サイクルエンジンの吸気装置。A passage with one end open and the other end open to the atmosphere is formed in the hole of the housing that slidably guides the intake valve, and when the intake valve is in the open state, the passage is connected to the inlet port. A groove is formed in the stem of the intake valve to communicate with the intake valve, and a negative pressure control valve is disposed in the passage, and the pressure chamber of the negative pressure control valve is communicated with the inlet port, so that the intake valve is in an open state. , and when the negative pressure in the inlet port falls below a predetermined pressure, the negative pressure operates the negative pressure control valve, thereby opening the passage and allowing atmospheric air to enter the inlet port. An intake system for a four-stroke engine, characterized in that it can be introduced.
