摘要：
The invention relates to a spark ignition device and an internal combustion device having said spark ignition device, wherein a plurality of spark electrodes (6-10) are disposed in an arc shape on the surface or so as to be projected from the surface of an insulating member (5) 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 (11-14,26).
A spark plug (3) is provided integrally with an injector (4), and the spark plug (3) and the ignition coil (15) are integrated. The three members are constructed as an integral unit, thereby improving installability to an engine.
The combustion engine having a piston (21) with a cavity (50) an the upper surface. The fuel is injected toward the cavity at least at the latter period of a compression stroke.
