Abstract
An internal combustion engine includes an intake air passage provided with a throttle valve, and an idling air passage by-passing the throttle valve and provided with an idling air flow rate adjusting device which includes a variable orifice. The orifice is formed by a stationary plate with an opening, and a movable plate in contact with and slidably movable with respect to the stationary plate. The two plates consist of this sheet material to prevent accumulation onto the surface of the orifice, of dust and oil particles contained in the intake air. The device further includes an adjusting screw connected to the movable plate to move the same with respect to the stationary plate to thereby adjust the opening degree of the opening in the stationary plate.
