Abstract:
An engine includes: a piston including a cavity; a cylinder head configured so as to form a combustion chamber having a pent roof shape; a fuel injection valve configured to inject fuel in a period from a second half of a compression stroke until a first half of an expansion stroke; and a spark plug arranged at a position corresponding to an upper side of the cavity. Injection openings which are arranged in a circumferential direction surrounding a longitudinal axis of the valve and through each of which the fuel is injected in a direction inclined relative to the longitudinal axis by a predetermined angle is formed such that when a height of a ceiling of the combustion chamber at a position corresponding to an edge end portion of the cavity in an injection direction of the injection opening is large, the injection angle of the injection opening is large.

Claim (Index 2):
The engine according to  claim 1 , wherein the injection angles of the injection openings are set such that each of injected fuel flow path lengths each of which is a length of a path along which the fuel injected from the injection opening flows through the cavity to reach the ceiling of the combustion chamber becomes equal to the injected fuel flow path length of the injection opening located closest to the spark plug.
