ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a cleaner for combustion systems and catalytic converters, and more particularly, to a method and apparatus used for cleaning the combustion chambers and fuel and exhaust passages of an internal combustion engine.
2. Description of the Prior Art
It is known to clean internal combustion engines by flushing out the engine with a cleaning fluid or other type of chemical solvent solution. Typical of such systems is U.S. Pat. No. 5,097,806, issued Mar. 24, 1992 and assigned to Winn Oil Company for a “Multi-mode Engine Cleaning Fluid Application, Apparatus and Method”. In the above-mentioned patent, a separate canister containing a liquid mixture of engine fuel and injector cleaning solvent is connected to the fuel line of an internal combustion engine, and the engine is operated using the fuel solvent mixture.
U.S. Pat. No. 5,381,810 issued Jan. 17, 1195 to Frederick Mosher. Columns 1 and 2 of this United States patent describe the background of the evolution of internal combustion engine cleaners and the problems of removing the buildup of carbon and other organic compounds on the internal engine surfaces.
As described in the Mosher patent, the mixture of fuel and solvent can also be problematic because the better the solvent, the more corrosive it can be which, of course, is detrimental to the internal surfaces of the engine. The solution proposed by Frederick Mosher is to more accurately control the pressure and pump speed to adjust the fuel cleaner solution pressure.
SUMMARY OF THE INVENTION
It is an aim of the present invention to provide a method and apparatus for readily cleaning an internal combustion engine of carbon deposits and other contaminants.
It is an aim of the present invention to provide a cleaning solution, which is a highly combustible fuel.
The method is dependent on the use of a fuel, which has been processed in accordance with the method described in co-pending International Application No. PCT/CA98/00367, filed Apr. 16, 1998, published Oct. 29, 1998 under Publication No. WO 98/47982, entitled “Fuel and Process for Fuel Production”, which is incorporated herein by reference. Furthermore, a molecular reactor for producing the fuel is described in International Application No. PCT/CA98/00454, filed May 8, 1998 and published Nov. 19, 1998 under Publication No. WO 98/51924 and entitled “Molecular Reactor for Fuel Induction”.
The process, in accordance with the above-mentioned published patent application WO98/47982, provides a highly combustible fuel vapor of negatively charged particles of fuel for use directly in the air/fuel manifold for an internal combustion engine. In the present invention, the vaporized fuel, which has been processed according to the above method, is allowed to condense and is distributed in a liquid form.
In accordance with the present invention, the condensed processed fuel is passed through a vessel provided with electrodes that provide a negative electrical charge to the molecules of the liquid fuel. The electrically charged fuel is then connected through the fuel line to the engine to be cleaned, and the engine is operated for approximately a half hour utilizing the electrically charged fuel, whereby the operation of the engine using the electrically charged fuel results in the cleaning of carbon deposits and other contaminants within the engine and the catalytic converter if such is connected to the exhaust.
An apparatus in accordance with the present invention includes a vessel for receiving a liquid fuel, at least an electrode protruding within the vessel, wherein the electrode has a negative polarity and the walls of the vessel or ground have a positive polarity, the vessel having an inlet and an outlet port, a pressure regulator at the inlet port for permitting air under pressure to enter into the vessel to pressurize the liquid fuel, and an outlet port for exhausting the charged fuel into the engine to be cleaned.
