の吸気装置。[Claims for Utility Model Registration] (1) An air cleaner, an upstream intake passage that communicates the uncleaned side of the air cleaner with the atmosphere, and a downstream intake passage that communicates the clean side of the air cleaner with the intake port of the engine body. A sub-suction port is opened in the middle of the upstream intake passage, a pressure regulating valve is provided in the sub-suction port, and when the inside of the upstream intake passage reaches a negative pressure of a predetermined value or more, the pressure regulating valve is opened. The intake system for an engine is characterized in that the pressure regulating valve is provided with a detection and display device that detects the opening of the valve and operates an indicator. (2) In the engine intake system according to claim (1) of the utility model registration, the detection display device includes a detector that detects the opening of the pressure regulating valve, and a detector that responds to a detection signal from this detector. An intake system for an engine, comprising: a display; and a timer that operates the display after a predetermined period of time has elapsed after the detector has been activated.
