A fuel spray is directed toward an ignition plug. To an injection bole outlet portion of a swirl type fuel injector, an L-shaped cut out is provided, and the fuel spray is formed with a deflection fuel spray which has a strong swirl component that can inject with a large quantity. Accordingly, a reduction in the discharge HC amount and an improvement in the fuel consumption can be attained.
