PURPOSE: An intake valve integrated with an injector is provided to prevent fuel from being injected into the wall of an intake port by forming the injector at a valve stem of the intake valve to inject the fuel into a combustion chamber. CONSTITUTION: A containing room is formed at the lower side of a valve face through the center of a valve stem. A body of a plunger(41) is contained in the containing room. A wing integrated with the body lies adjacent to a drive coil. The plunger opens a nozzle(34) to supply the fuel supplied from a fuel line(26) to a combustion chamber. A spring(46) is contained in the containing room to support the upper end of the plunger, and makes the plunger shut off the nozzle if the drive coil is not operated. A unit(50) is inserted into a valve mounting part of a cylinder head(20) to cover the wing of the plunger and the drive coil. An electronic control unit(60) controls the drive of the plunger according to the driving condition of an engine.
