ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to a magnetic fluid treatment method and apparatus for reducing the noxious emissions of internal combustion engines. More particularly, the invention is a magnetic fluid treatment apparatus providing a strong, focused magnetic field that is attached near or within an air/fuel mixing or injecting device.
BACKGROUND OF THE INVENTION
Magnetic apparatuses have been used for many years for the treatment of fluids, and in particular, for treating water, gasoline, or other fuel mixtures in both the liquid and gaseous state. The mechanism of operation of the magnetic apparatuses is based on a Lorentz Force, which is a resultant of the interaction of the magnetic field(s) of appropriately located magnets with moving ionic and atomic charges within a fluid or fluid spray. The magnetic interactions cause positive and negative charges within the moving fluid or fluid spray to alter trajectory, thereby causing collisions of supermolecules, or large molecules, and compounds in the fluid, which break apart these large molecules and compounds. “Supermolecules” are agglomerations of molecules. The resulting smaller molecules and compounds withing the moving fluid or fluid spray provide for improved mixing with air and other gases, and allow more complete combustion of fluid fuel or fluid spray thereof. The primary limitation of the prior apparatuses is the relatively slow movement of the fluid through the magnetic field. This limitation is because the speed of the positive and negative charges within the fluid or fluid spray media is a major contributor in creating the Lorentz Force, and thus, the subsequent breaking apart of the large molecules. A need exists for providing a treatment method and apparatus for air and fuel mixtures for an internal combustion engine to decrease noxious emissions of the engine.
OBJECTS OF THE INVENTION
The principal object of the present invention is to provide an improved magnetic fluid treatment apparatus for reducing the noxious emissions of engines which bum liquid or gaseous fuel mixtures with air.
Another object of the invention is to provide a magnetic fluid treatment apparatus having a strong, focused magnetic field that can be embedded within or mounted adjacent to a carburetor or another air and fuel mixing device.
A further object of the present invention is to provide a magnetic fluid treatment apparatus capable of generating a magnetic field having sufficient strength to affect a rapidly moving air and fuel mixture.
Another object of the invention is to provide a method for creating a magnetic field in a fuel delivery system at the point of maximum fuel mixture velocity
SUMMARY OF THE INVENTION
The present invention employs magnets positioned in close proximity to a fuel atomizing device such as a carburetor, injector, or other air/fuel mixing device. The magnetic fluid treatment apparatus generates a strong, focused magnetic field within the air and fuel stream immediately following the fuel mixing or dispensing device (i.e., venturi, nozzle, atomizer, spray jet, etc.). Preferably, the magnets are embedded within the wall of the carburetor in the vicinity of the primary venturi, a location within the carburetor where the air and fuel stream velocity is at a maximum. In another embodiment, the magnets are mounted adjacent the external surface of the wall of the carburetor downstream from the main fuel discharge jet. The position of the magnets within or adjacent to the carburetor maximizes the Lorentz Force by treating the air and fuel mixture in the carburetor at the point in the internal combustion engine where the speed of the fuel is at its maximum, thus resulting in the optimum utilization of the magnetic field generated by the magnets of the magnetic fluid treatment apparatus.
The magnetic fluid treatment apparatus uses modern technology magnetic materials to ensure that the magnetic field is as strong as is presently technologically achievable. The magnets are preferably made from a neodymium alloy such as neodymium-iron-boron (Nd
2
Fe
14
B), but also can be made from selenium cobalt or samarium cobalt alloys. However, the use of lesser strength magnetic fields is not excluded and will likewise result in an improved level of emissions reduction over the present state of the art. If multiple, adjoining magnets are used, the magnets are preferably bonded or glued together in a clamp or bracket. Because neodymium alloy magnets are prone to oxidation, it is preferred that they be coated to inhibit oxidation. This can be accomplished by electroplating the magnets, painting the magnets or encasing the magnets in resin.
