ABSTRACT:
An engine provided with a fuel injector for directly injecting fuel into a cylinder, a spark plug positioning a spark gap in a flight path of fuel injected from the fuel injector, and a cavity formed in a piston top face, wherein at the time of stratified combustion, the fuel injector injects substantially all of the fuel in a direction merging with a tumble flow, swirling in a longitudinal direction along the cavity at the compression stroke, along the swirl direction of the tumble flow and uses the spark plug to ignite the fuel while the fuel at the end period of injection is passing through the spark gap.
