A rotating fuel injector assembly for a vehicle engine includes a base, an internal tip, an intermediate coaxial tip, and an external coaxial tip. The internal tip may be configured to move between an extended closed position and a retracted open position relative to the base. The intermediate coaxial tip may include an opening defined in a base of the intermediate coaxial tip. The base and the opening abuts the internal tip when the internal tip is in the extended closed position. The external coaxial tip may move between an extended open position and a retracted closed position relative to the base. The external coaxial tip includes a plurality of apertures which may align with the at least one opening in the intermediate coaxial tip at a predetermined event.
