Abstract
Provided is an in-combustion chamber flow control device used in an engine having an intake passage connected to an intake opening formed in a ceiling surface of a combustion chamber, at an angle inclined with respect to a direction of an axis of a cylinder. This in-combustion chamber flow control device comprises a plasma actuator () disposed inside the combustion chamber (). The plasma actuator comprises: a dielectric body () disposed along the ceiling surface () of the combustion chamber, at a position closer to a center of the ceiling surface than the intake opening (); an exposed electrode () disposed on one side of the dielectric body facing the combustion chamber; and an embedded electrode () disposed on a side opposite to the exposed electrode across the dielectric body. The embedded electrode is disposed at a position closer to the intake opening than the exposed electrode.
