Engine with combustion chamber

An engine, comprising:

• 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 a plurality of injection holes 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,
• wherein the plurality of injection holes include a first injection hole and a second injection hole, and
• wherein the passage-forming member is disposed around the tip-end part of the fuel injection nozzle so as to cause a difference between a speed at which fuel injected from the first injection hole flows toward a circumferential part of the combustion chamber, and a speed at which fuel injected from the second injection hole flows toward the circumferential part of the combustion chamber.
