Abstract
A multipoint ignition engine () includes a central electrode pair (), disposed in the center of a combustion chamber (), for forming a central spark gap (), and a plurality of peripheral electrode pairs () held in a head gasket (), which has an opening portion having a substantially identical diameter to an opening portion of a cylinder () in a position corresponding to the opening portion of the cylinder (), for forming a plurality of peripheral spark gaps () around the inner periphery of the opening portion in the cylinder (). An air-fuel mixture in the combustion chamber (), which is obtained by mixing together fuel and air evenly to the stoichiometric air-fuel ratio or a richer/leaner air-fuel ratio than the stoichiometric air-fuel ratio, is ignited using both the central spark gap () and the plurality of peripheral spark gaps ().
