[Problems to be Solved by the Invention]

By the way, in the above-mentioned conventional cleaning apparatus, a high voltage current is used, which is very dangerous, and a voltage change occurs due to a change in the oil level due to the fuel processing in the fuel tank. However, there is a problem that it takes a long time to process the fuel and the mounting and removal of the conductive coil are not easy.

Therefore, the inventor of the present invention first invented a fuel cleaning device which is safe, easy to control, and low in cost by applying a low voltage and low current to fuel and / or water during refueling. Japanese Patent Application No. 4-25929, Japanese Patent Application No. 5-23223
No.). However, since a conductive coil is used to apply this low voltage and low current to the fuel and / or water, the electrostatic induction electric field is applied to the fuel when the fluid inside the oil supply pipe or the like flows without being sufficiently filled. There is a possibility that the fuel cannot be sufficiently worked to completely clean the fuel.

The present invention has been made in view of the above problems of the prior art, and an object thereof is to apply a low voltage, low current to fuel and / or water during refueling. By using the arc-shaped conductive plates facing each other, it is intended to provide a reliable fuel cleaning device which is safe, easy to control, and low in cost.

In order to achieve the above-mentioned object, a fuel cleaning apparatus according to the present invention comprises a fuel distribution synthetic resin pipe connected in a fuel supply pipe between a fuel tank and an engine.

It is characterized by being applied to a conductive plate.

Further, in the hydrous fuel supply device having a fuel supply conduit from the fuel tank, a water supply conduit from the water tank, and a hydrous fuel supply conduit for supplying the hydrous fuel to the engine, at least the water supply conduit and the hydrous fuel supply pipe On the outer circumference of the synthetic resin pipe connected in the road, arc-shaped conductive plates facing each other along the outer circumference of the resin pipe are arranged, and the outer circumference is covered with a protective cover, so that the low voltage from the AC signal generator connected to the battery is reduced. The present invention is characterized in that a low current of low frequency and low voltage is applied to the arc-shaped conductive plate.

[0008]

[Function] The fuel and / or water are dissolved in the fuel and / or water by causing a molecular fluctuation in the fuel and / or water by causing an electrostatic induction electric field to act on the fuel and / or water from the opposing arc-shaped conductive plates by a low current of low frequency and low voltage. Oxygen can be increased, and NOx or CO contained in exhaust gas after being used in the engine can be significantly reduced. Since this processing is performed in the middle of the fuel supply pipe between the storage tank and the engine, the electrostatic induction field acts uniformly on the fuel and / or water to be supplied, so that the entire fuel and / or water is supplied with the fuel and / or water. Facilitate the modification of. Even when a small amount of fuel and / or water is supplied and only a part of the fuel supply pipe is made to flow down, if a part of the flowing fuel and / or water falls within the area of the arc-shaped conductive plates facing each other, it will be quiet. It is surely cleaned by the action of the electric field.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT A first embodiment of the present invention will be described with reference to FIGS. In the figure, reference numeral 1 denotes a fuel tank mounted on an automobile or the like, a fuel supply pipe 2 is arranged between the fuel tank 1 and an engine (not shown), and a fuel supply pipe 2 is provided in the middle of the fuel supply pipe 2.

On the outer circumference of the fuel-flowing synthetic resin tube 3, arc-shaped conductive plates 4 facing each other are arranged along the outer circumference of the resin tube. The arc-shaped conductive plates 4 prevent the conductive plates from being displaced due to vibrations and damage. It is covered with a protective cover 5 for prevention. Further, screws 6 are formed at both ends of the fuel distribution synthetic resin pipe 3, and the fuel distribution synthetic resin pipe 3 is connected to the fuel supply pipe 2 by the screws 6, 6.

It is selectively controlled in the range of 1.8 mmA according to the type of fuel, and it is 30H in the frequency generation circuit 10.
Low frequencies of z to 130 Hz can be generated. In addition, the transformer circuit 11 transforms the voltage so that a voltage can be applied between the arc-shaped conductive plates 4 in the range of 1 V to 3 V according to the type of fuel.

It is advisable to select about 1.5 mmA to relatively reduce the increase in oxygen content, and in the case of gasoline, frequency 30-60 Hz, voltage 1-
As a result of an experiment, it was found that it is better to select 3 V and a current of about 800 μA to 1.8 mmA and relatively increase the amount of oxygen contained. The current / voltage value is slightly higher than that when the conductive coil is used because the conductive plate has a little more current / voltage loss than the conductive coil.

Since the arc-shaped conductive plate 4 always forms a constant electrostatic induction electric field between the electrode plates 4 by the electrodes, the fuel supply amount is small and only a part of the fuel supply pipe flows down. Even in such a case, if a part of the flowing fuel falls on the area of the arc-shaped conductive plates facing each other, the fuel is surely cleaned by the action of the electrostatic induction electric field.

After increasing the dissolved oxygen, it may be mixed with the water whose specific gravity is reduced.

In the above case, for example, the current is controlled to 10 mmA by the AC signal generator 7, the frequency is 50 Hz and the voltage is 10 V, which is sent to the device 17, and
For example, the AC signal generator 7 controls the current to 2 to 5 mmA, the frequency is 180 Hz and the voltage is 1.5 V, and the voltage is sent to the device 18. Further, for example, the AC signal generator 7 controls the current to 5 mmA. Frequency of 100 to 1

[0018]

According to the present invention, the fuel is subjected to an electrostatic induction field due to a low current of a low frequency and a low voltage through an arc-shaped conductive plate, whereby a molecular fluctuation is given to the fuel to dissolve dissolved oxygen in the fuel. It can be increased and NOx or CO contained in the exhaust gas after being used in the engine can be remarkably reduced, which is very advantageous in terms of pollution control. In the case of an arc-shaped conductive plate, if a part of the fuel falls within the area of the arc-shaped conductive plate facing the fuel, the fuel is reliably cleaned by the action of the electrostatic induction electric field. Also, in this case, the fuel can be surely cleaned, the production is easier than the coil, and there is no fear of disconnection.
