    Abstract: The present disclosure provides a fuel injection unit for an internal combustion engine. The fuel injection unit includes: a separator that is disposed in an intake port to supply air into a combustion chamber formed in an engine head, and that divides a channel for air into an upper channel and a lower channel; a blade disposed ahead of the separator and opening or closing the upper channel or the lower channel by rotating; and a first injector disposed over the intake port. In particular, when the first injector injects fuel, the blade does not interfere with the fuel.
