Abstract
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.
Claims20
A rotating fuel injector assembly comprising:
- a base having a fuel inlet and a fuel outlet;
- an internal tip operatively configured to move between an extended closed position relative the base and a retracted open position relative to the base;
- an intermediate coaxial tip having an opening defined in a lower region of the intermediate coaxial tip, and the opening abutting the internal tip when the internal tip is in the extended closed position, the intermediate coaxial tip being affixed to the base;
- and
- an external coaxial tip operatively configured to rotate relative to the base and configured to move between an extended position and a retracted position relative to the base, the external coaxial tip having a plurality of apertures, each aperture in the plurality of apertures operatively configured to align with the opening of the intermediate coaxial tip;
- wherein the internal tip is partially disposed within the intermediate coaxial tip, and the intermediate coaxial tip is at least partially disposed within the external coaxial tip.
A rotating fuel injector assembly comprising:
- a base defining a plurality of fuel passageways and having a fuel inlet in addition to a fuel outlet;
- a first actuator, a second actuator, a third actuator and a fourth actuator affixed to the base and being in communication with an engine control module;
- an internal tip operatively configured to move between an extended closed position and a retracted open position relative to the base along a vertical axis, the internal tip being triggered by the fourth actuator;
- an intermediate coaxial tip affixed to the base and defining an opening in a lower region of the intermediate coaxial tip, the opening abutting the internal tip when the internal tip is in the extended closed position;
- and
- an external coaxial tip operatively configured to move between an extended position and a retracted position relative to the base, the external coaxial tip having a plurality of apertures, each aperture in the plurality of apertures being configured to align with the opening defined in the intermediate coaxial tip, and each aperture in the plurality of apertures having a unique axis angle;
- wherein the intermediate coaxial tip and the external coaxial tip being configured to rotate about the vertical axis via the first and second actuators.
