PURPOSE:To stably take out intake air pressure by taking out intake air pressure for controlling an engine from an intake passage on the lower course side of a timing valve when this valve is closed, in a device in which said timing valve is provided in an intake passage near an intake port. CONSTITUTION:An intake passage 10 is branched, on the lower course side of a surge tank 13, to an intake passage 10a for high load and an intake passage 10b for low load which is formed for producing a swirl, and a shutter valve 17 is provided in the passage 10a and a timing valve 18 is provided in the passage 10b. A connecting groove 18b is formed on the peripheral part of the timing valve 18 in a position slipped off from its opening 18a. A connecting port 22 which is connected to this connecting groove 18b, is opened on the intake passage 10b for low load, on the lower course side of the valve 18. And, this connecting port 22 is connected openably/closably to a pressure take-out port 21 which is connected to a combustion pressure regulator 19 via a passage 20.
