Beschreibung
Zusammenfassung:	An engine is provided, which includes a combustion chamber defined by a cylinder head and a piston inside a cylinder of a cylinder block, a fuel injection nozzle provided to the cylinder head and formed in a tip-end part with an injection hole from which fuel is injected into the combustion chamber, the tip-end part being exposed to the combustion chamber, and a passage-forming member formed with a passage through which the fuel injected from the injection hole passes. An outer circumferential surface of the passage-forming member contacts a combustion-chamber ceiling surface of the cylinder head, and the passage of the passage-forming member includes an enlarged part gradually increasing in a cross-sectional area thereof from an upstream side to a downstream side of the passage.
