A plasma generation device (30) for generating electromagnetic wave plasma by emitting electromagnetic waves in a combustion chamber (21) in an internal combustion engine (20), wherein the combustion is promoted by increasing the contact between the electromagnetic wave plasma and the gas in the combustion chamber (21). An antenna (36) extends along the ceiling surface of the combustion chamber (21). A regulator (37), for altering the position of a strong electric field in the antenna when the electromagnetic waves have been supplied, is provided. During the electromagnetic wave plasma generation period, a control device (10) controls the regulator (37) and alters the position of the electromagnetic wave plasma on the basis of the state of the combustion chamber (21). |
