特徴とする空気供給装置。 Each cylinder connects an intake valve, an intake port upstream of the intake valve, a cutoff valve capable of blocking the intake port so that it has a predetermined volume, and an upstream side and a downstream side of the cutoff valve. In a multi-cylinder internal combustion engine each comprising a sub-intake pipe and a control valve for opening and closing the sub-intake pipe, means for measuring the average effective pressure of each cylinder at least when the engine is idling; When the average effective pressure of some of the cylinders differs by a predetermined value or more compared to the average value of the average effective pressure in the previous cycle, the sub-intake is supplied to the intake ports of the some of the cylinders. An air supply device comprising: an electronic control device that operates to correct the opening/closing period of the control valve in order to increase or decrease the amount of air supplied from the pipe.
