ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a fuel-reforming sheet and method of manufacture thereof for improving the fuel efficiencies of various types of heat engines, such as those used in work trucks, buses, passenger cars, marine vessels and boilers, which use liquid fuels such as gasoline, light fuel oil, heavy fuel oil and methanol, and gas fuels such as LPG and natural gas, while at the same time making it possible to drastically reduce emissions such as CO, HC and black smoke (produced by Diesel engines) in the exhaust gas of such heat engines.
2. Description of the Prior Art
In the field of fuel-reforming devices, the present inventor previously invented a fuel-reforming device (disclosed in Japanese Utility Model Application No. HEI 8-10566) in which a ceramic powder and a radioactive rare-earth mineral powder were mixed, granulated, dried, baked, grounded to form spherically shaped grains having roughly the same diameter, and filled into a cylindrical body which has pores smaller than the diameter of such spherically shaped grains formed in the circumferential surface and in the surface of cover portions of the cylindrical body. In this connection, the cylindrical body was given a porosity of 50% and was filled with the spherically shaped grains to have a fill ratio of 90%. Further, one cover portion of the cylindrical body was provided with a rotary-type chain such as a ball chain, and the other cover portion was provided with a fitting member such as a ring-type coupling.
However, the requirement of a baking step or the like when processing the ceramic powder and radioactive rare-earth mineral powder makes it time-consuming and expensive to manufacture such a fuel-reforming device. Furthermore, there is the inconvenience of having to place such a fuel-reforming device inside the fuel tank.
SUMMARY OF THE INVENTION
With a view toward overcoming the problems of the prior art stated above, it is an object of the present invention to provide a fuel-reforming sheet which is adapted to be placed in the air flow channel of a heat engine to ionize the oxygen molecules in the air in order to achieve complete combustion of the oxygen mixed with the fuel and thereby improve the power and fuel efficiency of the heat engine, while at the same time reducing unwanted emissions in the exhaust gas. It is a further object of the present invention to provide a fuel-reforming sheet made from a sheet-shaped backing having powder grains firmly bonded thereto. It is another object of the present invention to provide a method of manufacturing the fuel-reforming sheet according to the present invention.
In order to achieve these objects, the fuel-reforming sheet according to the present invention is constructed from a flexible backing, a double-sided adhesive sheet having a back surface which is bonded to the flexible backing, and a powdered mixture which is bonded to a front surface of the double-sided adhesive sheet, with the powdered mixture including a ceramic powder, a radioactive rare-earth mineral powder and a binder.
Further, in the fuel-reforming sheet according to the present invention, the ceramic powder and the radioactive rare-earth mineral powder have a grain size in the range of 250-350 mesh.
As for the flexible backing of the fuel-reforming sheet according to the present invention, it is possible to use a thin stainless steel sheet or a heat-resistant, cold-resistant and weather-resistant thermoplastic resin sheet.
Further, in the fuel-reforming sheet according to the present invention, the powdered mixture may also include sericite as a filler and magnetite may be used as the binder.
In the method of manufacturing a fuel-reforming sheet according to the present invention, a back adhesive surface of an ultrathin double-sided adhesive tape is first bonded to a flexible backing, and then after removing a release paper from a front adhesive surface of the double-sided adhesive tape, a powdered mixture comprising a ceramic powder, a radioactive rare-earth mineral powder and a binder is air sprayed onto the front adhesive surface of the double-sided adhesive tape to bond the powdered mixture to the double-sided adhesive tape.
