Abstract
An internal combustion engine includes a fuel injection nozzle in which a nozzle hole that injects fuel is provided to be exposed to a combustion chamber from a cylinder head of the internal combustion engine, and a hollow duct in which an inlet and an outlet are exposed to the combustion chamber. The duct is provided to penetrate through an inside of the cylinder head so that fuel spray injected from the nozzle hole of the fuel injection nozzle passes from the inlet to the outlet. The duct is preferably configured so that a direction from the inlet to the outlet corresponds to a direction of the fuel spray injected from the nozzle hole.
