To provide a technology for an engine in which an air-fuel mixture flowing into an ignition chamber from a combustion chamber through a nozzle hole is spark-ignited at an ignition point by an ignition plug, which is achieved in the sure leading of the air-fuel mixture to the ignition point and the prevention of the occurrence of a misfire thereby providing stable combustion flame and achieving stable operation.
The ignition plug 7 in which the ignition chamber 8 is formed in a plug cover 7b covering the ignition point P is loaded in a cylinder head 6, the plurality of nozzle holes 10 are formed at the plug cover 7b, the ignition chamber 8 comprises throat spaces 8a formed at the nozzle holes 10 and an ignition space 8b communicating with the throat space 8a and having the ignition point P. The inside diameter of the throat space 8a is formed to be smaller than that of the ignition space 8b. The center axis Y of the throat space 8a is set to be parallel to the center axis X of the ignition space 8b and shifted by a predetermined distance D from the center axis X. The throat space 8a is arranged at the end of the ignition space 8b in a direction orthogonal to the center axis X of the ignition space 8b.
