摘要： To alleviate or eliminate a problem of unburned fuel discharged to the outside of a cylinder in a case in which an air fuel mixture is insufficiently combusted in a combustion chamber. During the expansion stroke in which a high voltage is applied to an ignition plug via an ignition coil, and a spark discharge is caused to occur at the ignition plug, thereby the air fuel mixture in the combustion chamber is ignited and combusted, in a case in which deterioration of combustion state is detected, a microwave electric field is created in the combustion chamber prior to an opening timing of an exhaust valve at an end stage of the expansion stroke, thereby plasma is generated and enlarged in the combustion chamber.

摘要： An analysis apparatus includes a plasma generation unit and an optical analysis unit. The plasma generation unit generates initial plasma by momentarily energizing a target substance to be turned into a plasma state, and maintains the target substance in the plasma state by irradiating the initial plasma with an electromagnetic wave for a predetermined period of time. The optical analysis unit identifies the target substance based on information with respect to emission intensity during a period from when the emission intensity reaches a peak due to the initial plasma until when the emission intensity increases and reaches approximately a constant value due to electromagnetic wave plasma maintained by the electromagnetic wave, or information with respect to emission intensity after the electromagnetic wave irradiation is terminated.
