Abstract:
An internal combustion engine comprises a fuel injector  31 , a spark plug  16 , a piston  14  having a cavity  91 , a swirl control device  95 , and a control system  70 . The cavity is formed so as to change in distance from the fuel injector to a side wall surface of the cavity, in the circumferential direction. The system performs ignition assist control for successively performing injections of main fuel and ignition assist fuel, makes an air-fuel mixture formed by the ignition assist fuel burn by flame propagation by the spark plug, and makes the remaining fuel burn by pre-mix compression self-ignition. The system controls the swirl control device during the ignition assist control so that when the engine load is high, the fuel sprayed heads toward parts of the side wall surface which are short in distances from the fuel injector.

Claim (Index 6):
The internal combustion engine according to  claim 3 , wherein said fuel injector has a number of spray holes equal to the number of said inside projecting parts of said cavity, and the spray holes of said fuel injector and said inside projecting parts are arranged at equal intervals in the circumferential direction of a cylinder.
