機関の給気制御装置。 A two-stroke internal combustion engine with an air intake valve and an exhaust valve installed in the cylinder head is equipped with a movable mask plate that protrudes into the air intake port and can close the opening on the exhaust valve side formed between the air intake valve and its valve seat. During the first half of the intake valve opening period, the movable mask plate closes the exhaust valve side opening formed between the intake valve and its valve seat, and during the second half of the intake valve opening period, the movable mask plate closes the opening formed between the intake valve and its valve seat. An air supply control device for a two-stroke internal combustion engine, in which an opening formed between an air supply valve and its valve seat is opened all around by retracting a mask plate.
