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 that is equipped with an auxiliary intake pipe and a control valve that opens and closes the auxiliary intake pipe, a booster, which is a booster for hydraulic operation, is connected only to the intake port of a specific cylinder. While the pressure extraction pipe is connected,
When the booster is operated to consume negative pressure,
An air supply device comprising: an electronic control device that operates to reduce and correct a valve opening period of the control valve that supplies air to the intake port of the specific cylinder.
