Description

FUEL ECONOMIZER

Background of the Invention

1. Field of the Invention This invention relates to a fuel economizer, and more particularly to, an improved fuel economizer which accelerates the movement of fuel by strong wave motion and activates the fuel with far infrared ray of bio- ceramic members, so as to increase the engine output and save the fuel.

?. . Description of the Prior Art

In general, a fuel air mixer arranged in an engine of an automobile or a vessel requires the highly precise control in order to attain a purification of exhaust gas, reduction of the fuel consumption, and output improvement.

A fuel injector device is to electrically detect the amount of intake air and to eject the fuel corresponding to the operation condition of the engine according to the detection result. In order to control the device, a controller is usually used.

An injector to eject the fuel to intake manifolds of cylinders according to signals received from the controller includes a solenoid coil plunger, a needle valve, etc. When current is on a solenoid coil, the plunger is put under pressure such that the needle valve formed integrally with the plunger opens a discharge hole so as to discharge the fuel.

The discharge rate depends on the time that the needle valve is being opened, i.e., the resistance time of the solenoid coil.

The injector is operated by a current controlled electric circuit or a voltage controlled electric circuit. The voltage controlled electric circuit controls the injector in a way that resistance is put in the injector in series to reduce voltage.

When turning on an ignition switch, the current flows from a resistor through the injector to the controller.

In the controller, current flows to a base of a power transistor by signal of the fuel injection. When the transistor is turned on, an earth circuit is made in the injector so as for current to flow into the injector, thereby discharging the fuel.

The resistance put in the injector in series is used to improve the reply efficiency of the injector.

In order to improve the reply efficiency of the injector, if the resistance value of the injector is reduced, the voltage is decreased in the injector so as to prevent the heat generation of the solenoid coil.

The current controlled electric circuit doesn' t require the resistor, but directly applies the battery voltage to the injector in order to improve the reply efficiency of the injector. The current controlled electric circuit is controlled in the resistance time by the controller in the same way as the voltage controlled electric circuit.

The control of the current of the injector allows great current to flow into the injector when sucking the plunger, so as to improve the reply efficiency of the injector, thereby reducing the time of ineffective injection. Furthermore, when maintaining the plunger, small current flows into the injector so as to prevent the heat generation of the injector coil and to reduce the consumption of electricity.

In the meantime, it is well-known theory that the so-called "lean combustion" that the fuel is eddied in a combustion chamber and the mixture ratio near the ignition plug becomes concentrated can lead the flow acceleration of the engine such that "perfect combustion" of the fuel is performed so as to attain the increase of the output and the fuel economy effect.

Therefore, there are many kinds of fuel economizers including a screw for making the fuel eddy in an inlet portion connected to the engine.

Some of the previously used fuel economizers can increase the explosive force through the lean combustion and attain the fuel economy effect through the perfect combustion to some degree.

However, the conventional fuel economizers cannot give the fuel economy effect as good as users' expectations, because not making the properties of the fuel itself change and not making the fuel eddy strong.

Summary of the Invention

It is, therefore, an object of the present invention to provide an improved fuel economizer that accelerates the supply of the fuel so as to improve the effect of the lean combustion which has the mixture ratio become concentrated. Another object of the present invention is to provide an improved fuel economizer that activates the molecule of the fuel with far infrared ray to facilitate the perfect combustion, thereby increasing the output of the engine and fuel economy effect. Still another object of the present invention is to provide an improved fuel economizer that has the small number of components, that is relatively inexpensive, and that is conveniently repaired.

The foregoing objects are accomplished in the present invention by providing a fuel economizer which has a first case, a second case, a cylindrical case body, an undulated member, a housing, bio-ceramic members for activating the fuel with far infrared ray, and a fixing cap. The first case has a lead-in nipple for connecting to a fuel pipe of a fuel tank and the second case has a discharge nipple for connecting to a fuel pipe of an engine.

The case body is a hollow cylindrical shape and located between the first case and the second case by a screw coupling.

The undulated member has a space therein. The space has an end portion which is open and the other end portion which is blind. The undulated member is situated in the combined first case, second case and case body, maintaining fine gap between projecting portions of the undulated member and an inner diameter of the case body. The housing covers the combined first case, second case and case body. Between the housing and the cases, a space is formed.

The bio-ceramic members are filled in the space of the undulated member and the space between the case body and the housing, so as to activate the fuel passing through the fine gaps with far infrared ray.

The fixing cap is screwed with the open portion of the undulated member to seal the open portion of the space of the undulated member filled with the bio-ceramic member. The fixing cap has a supporting plate disposed at a front portion of the fixing cap and having a plurality of holes for passing the fuel through the holes.

The foregoing and other objects and features of the present invention will become more fully apparent to persons of ordinary skill in the art from the following description and appended claims, taken in conjunction with the accompanying drawings.

Brief Description of the Drawings

Understanding that these drawings depict only typical embodiments of the invention and are, therefore, not to be considered limiting of its scope, the invention will be described with additional specificity and detail through use of the accompanying drawings in which: Figure 1 is a longitudinal sectional view illustrating essential components of this invention;

Figure 2 is a longitudinal sectional view of a modified embodiment of an undulated member of this invention; Figure 3 is an enlarged view of "A" portion of Figure 2;

Figure 4 is a transverse sectional view of Figure 2; and,

Figure 5 is an enlarged view of "B" portion of Figure 4.

Detailed Description of the Preferred Embodiments

Figure 1 is a sectional view illustrating a construction of the present invention. In figure 1, a fuel economizer according to the present invention includes a first case 10 having a lead-in nipple 11, a second case 20 having a discharge nipple 21, and a case body 30 located between the first case 10 and the second case 20 by a screw coupling. An undulated member 40 which has a space 50 having an end portion which is open and the other end portion which is blind, and a fixing cap 60 which seals the open end portion of the undulated member 40 are inserted into the cylindrical case body 30. After that, the first case 10 and the second case 20 are respectively screwed to opposite end portions of the case body 30.

As shown in Figure 1, the undulated member 40 has a tooth shape in its undulation form, and the fuel passes through a fine gap formed between the case body 30 and projecting portions of the undulated member 40.

Figure 2 is a longitudinal sectional view of another embodiment of the undulated member 40 having an asymmetrical mountain shape in its undulation form. The undulated member 40 of Figure 2 has the same function as the undulated member 40 of Figure 1.

Figure 3 is an enlarged view of "A" portion of Figure 2. In Figure 3, the projecting portions of the undulated member 40 include a plurality of grooves 41 along their ends.

As shown in Figures 3 to 5, the grooves 41 of the undulated member 40 allow the fuel to pass through the grooves 42, thus creating strong wave motion and effect of accelerated injection. The lead-in nipple 11 is connected to a fuel pipe of a fuel tank and the discharge nipple 21 is connected to a fuel pipe of an engine. Thus, the fuel supplied from the fuel tank changes physically and chemically while passing through this fuel economizer. In order to attain the effect of the acceleration injection, it is preferable that the undulated member 40 has a plurality of grooves 41 along the ends of each of the projecting portions so that the fuel passes through the grooves 41 with the strong wave motion. Though the tolerance is caused by accuracy of proceeding of the case body 30 and the undulated member 40, or the fine gap is clogged with foreign matter such that the fuel cannot pass through the fine gap, the fuel can be surely supplied through the grooves 41 of the undulated member 40 to the engine.

As previously described above, the fuel is supplied through the fine gap between the case body 30 and the undulated member 40 and through the grooves 41 of the undulated member 40, with strong wave motion. At this time, the speed of injection can be increased by the formular as follows:

Q = VA (Q = total flow rate, V = speed, A = sectional area) As you can see from the formular, supposing that total flow is uniform, the rate of injection increases while the sectional area gets narrow.

When the rate of the fuel injection is increased instantaneously in the case body 30, and the fuel of the strong wave motion is discharged from the engine, it can be attained to perform the perfect combustion through the lean combustion, to save the fuel, and to reduce the production of the harmful exhaust gas.

The combined first case 10, second case 20 and case body 30 is covered by a housing 45, maintaining a predetermined space between the cases and the housing 45.

The housing 45 has a plurality of sections to be screwed one another in one united body.

Bio-ceramic members 50 closely fill the space of the undulated member 40 and the space between the combined case and the housing 45.

The bio-ceramic members 50 make the fuel passing between the case body 30 and the undulated member 40 activate with far infrared ray. The bio-ceramic members 50 filling the spaces of the undulated member 40 and the housing 45 not only activate the fuel with far infrared ray but also prevent the freezing of the fuel in the cold winter season. As previously described above, the space 42 of the undulated member 40 filled with the bio-ceramic member 50 is sealed with the fixing cap 60 and each of sections of the housing 45 filled with the bio-ceramic member 50 are sealably screwed one another. Thus the bio-ceramic members 50 can maintain the effect of far infrared ray for a long time.

The fixing cap 60 which is screwed with the open end portion of the undulated member 40 includes an integral supporting plate 62 at the front portion thereof. The supporting plate 62 has a plurality of holes 61 for allowing the fuel flowing through the first case 10 to pass through the fine gap between the case body 30 and the undulated member 40.

The other end portion of the undulated member 40 has the same shape as the fixing cap 60.

The supporting plate 62 of the fixing cap 60 has the same diameter as an inner diameter of the case body 30. The diameter of the fixing cap 60 is somewhat larger than that of the projecting portions of the undulated member 40. Thus, the undulated member 40 can be located inside the case body 30, maintaining fine gap through which the fuel passes. When the fuel passes through the fine gap under the pressure of the fuel pump, the fuel is atomized and the passage speed is accelerated. The fixing cap 60 and the end portion of the undulated member 40 formed as the above allow the fuel to pass through the holes 61 of the fixing cap 60 through the fine gap and through holes of the end portion of the undulated member 40. The fuel passing through the holes of the end portion of the undulated member 40 is discharged through the discharge nipple 21 of the second case 20 and supplied to the combustion chamber of the engine. When the fuel passes through the case body 30, the undulated member 40 creates the strong and fast wave motion and the acceleration force and the bio-ceramic members 50 activates the fuel with far infrared ray to facilitate the combustion of the fuel. Those skilled in the art will readily recognize that these and various other modifications and changes may be made to the present invention without strictly following the exemplary application illustrated and described herein and without departing from the true spirit and scope of the present invention.
