Abstract:
1. An internal-combustion engine, comprising: an intake valve for opening and closing a combustion chamber; an exhaust valve for opening and closing the combustion chamber; a driving mechanism for driving both the intake valve and the exhaust valve; a control device; and a plasma generator positioned within a region containing gas used for combustion during a combustion stroke, the plasma generator comprising wherein the control device instructs electromagnetic-wave radiation source to radiate the electromagnetic pulse at any point during a timing that starts when exhausting concludes and ends before the intake starts, and is set according to a valve-timing setting in the driving mechanism, thereby activating burnt gas remaining in the combustion chamber after combustion, and wherein the electromagnetic pulse has a frequency in the GHz band and the duration of the electromagnetic pulse is approximately one microsecond or less.
