Abstract
Provided is an ignition plug (15) that has an antenna (54) for emitting high-frequency EM waves to combustion chamber (20) of an internal combustion engine (10), wherein the propagation velocity of the flame is augmented using the high-frequency EM waves emitted from the antenna (54). The ignition plug (15) has an ignition plug body (30) and an antenna (54). The antenna (54) is located on the front-tip side surface of the cylindrical second conductive member (33) within the ignition plug body (30), which accommodates a rod-shaped first conductive member (31) and cylindrical insulation (32) surrounding the first conductive member (31).
Claims8
An ignition plug comprising:
- an ignition plug body having a rod-shaped first conductive member, cylindrical insulating material surrounding the first conductive member, and a cylindrical second conductive member that accommodates the first conductive member and the insulating material, wherein an air-fuel mixture within the combustion chamber is ignited when a potential difference is applied between the first and the second conductive members, and electricity is discharged on the front-tip side that is exposed to the combustion chamber of the internal combustion engine;
- and
- an antenna attached to the ignition plug body that emits high-frequency EM radiation, which is externally provided, to the combustion chamber;
- the antenna is located on the front-tip side surface of the second conductive member.
