Abstract
A plurality of spark electrodes are disposed in an arc shape on the surface or so as to be projected from the surface of an insulating member formed on a part of the wall face of a combustion chamber, and are formed so as to be in series electrically via discharging gaps. A spark plug is provided integrally with an injector, and the spark plug and the ignition coil are integrated. The three members are constructed as an integral unit, thereby improving installability to an engine.
