The present invention relates to an exhaust gas reducing fuel reducer for an internal combustion engine, and more particularly, is installed on a fuel supply line of an internal combustion engine to pressurize and diffuse fuel, and at the same time, atomize molecules to achieve complete combustion of fuel. TECHNICAL FIELD The present invention relates to an engine exhaust fuel saving fuel reducer.

In general, a mixer supplied to an engine such as an internal combustion engine used in an automobile or a ship requires very precise control to simultaneously satisfy reduction of exhaust gas, reduction of fuel consumption, and output improvement.

The fuel injection device applied to the internal combustion engine electrically detects the intake air amount and injects the fuel according to the detected air intake to suit the operating conditions of the engine. The fuel injection device includes a control unit.

The injector is a component that injects fuel into the intake manifold of each cylinder in response to a signal from the controller.It consists of a solenoid coil plunger and a needle valve, and when the current flows through the solenoid coil, the plunger is sucked and formed integrally with the plunger. By opening the injection port by pulling the needle valve which is present serves to inject the fuel.

In the above operation, the injection amount of fuel is determined by the time when the needle valve is opened, that is, the time when the solenoid coil is energized.

The electric circuit for operating such an injector is roughly divided into a voltage control type and a current control type. The voltage control type and the current control type are determined by the use of a resistor (register).

On the other hand, the fuel inlet is installed on the inlet side connected to the engine to cause a swirl flow of the fuel injected from the injector, this fuel saver is known in various forms, for example, the present inventors Fuel savings such as 2004-0005552 have been proposed.

The prior art is an inlet-side housing to which the fuel pipe on the fuel tank side is connected, a first permanent magnet fixed to the inside of the inlet-side housing, and coupled to the inlet-side housing by coupling means, one end of the engine-side fuel tube The discharge side housing to be connected, the second permanent magnet fixed to face the same polarity as the first permanent magnet in the discharge side housing, and installed in the middle portion of the housing to partition the interior of the housing, the fuel passage hole in the center A formed diaphragm, a third permanent magnet installed on the fuel inlet side of the diaphragm, a fourth permanent magnet installed on the fuel discharge side of the diaphragm and provided with a first ball retractable in the through hole, and installed on one side of the diaphragm. And a sleeve having a fuel passage hole formed at the center thereof, and installed on the fuel passage hole of the sleeve to open and close the fuel passage hole by the magnetic force of the fourth permanent magnet. A second ball for miniaturizing the fuel, a cap provided on one side of the sleeve, and a plurality of fuel supply holes formed so that the fuel is supplied to the combustion chamber side as the second ball opens the fuel passage hole of the sleeve by pressing the activator; And a first diffuser plate provided in the inlet-side housing to diffuse fuel primarily, and a second diffuser plate installed in the discharge-side housing to secondary diffuse and refine the fuel.

However, the prior art has the disadvantage that the surface coating layer of the permanent magnet is continuously exposed to the fuel, such as oxidation and corrosion, and the magnet flows due to the gap between the magnets or the minute vibration is repeated, the magnetic force is sharply reduced or the magnet There was a problem of weak durability, such as a problem such as cracking.

In addition, since there is not enough space between the first ball and the fourth permanent magnet provided to be able to move in and out of the fourth permanent magnet, when fine debris accumulates in the fuel, the fuel does not pass and is blocked. Since the position is determined depending on the Gaussian size of the permanent magnet and the third permanent magnet, it is necessary to measure and assemble the Gaussian of each magnet one by one. There was a problem that the durability and stability are not good, such as the ball retreating up to the third permanent magnet to go out with the first diffusion plate to damage the diffusion wing.

Accordingly, the present invention devised to solve the above problems is to atomize while spreading the fuel several times in the process of supplying fuel by a pair of diffusion plate, a plurality of permanent magnets (ring magnet), and a metal ball It is possible to achieve complete combustion, to reduce exhaust gas due to the complete combustion of fuel, and to improve the durability and stability of the fuel saver for realizing this, while increasing the output power by increasing the explosive power according to the complete combustion. The purpose is to provide an exhaust gas reducing fuel saver for an internal combustion engine.

The present invention for achieving the above object is a housing coupled to the inlet-side housing is connected to the fuel tank side fuel pipe at one end and the discharge-side housing is connected to the engine side fuel pipe at the other end, and the ring magnet at each housing inner end; The diffuser is mounted in sequence, the inner center of the housing, the sleeve is provided so that the spherical sleeve ball in the fuel cylinder hole can be retracted, a plurality of discharge holes are provided, the cap coupled to the fuel cylinder hole on the sleeve, the plurality of fuel cylinder holes An exhaust gas reducing fuel saver for an internal combustion engine is provided, in which ring magnets are inherently overlapped and have a combination of a sleeve body coupled to a lower portion of the sleeve, wherein a wall of the inner end of the outlet housing is curved to diffuse the fuel. Corresponding to each of the ring magnets superimposed within the sleeve body and on the outermost side respectively. Characterized in that a washer is interposed in the size of the ring magnet and the interior of the washer has a convex surface on the inner surface being formed with a projection formed on one end of the ball bushing is moved forward and backward can be provided in the cylindrical inner bushing within the

Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to FIGS. 1 to 3.

1 is an exploded perspective view of a fuel saver according to an embodiment of the present invention, Figure 2 is a longitudinal cross-sectional view showing the assembled state of the fuel saver according to an embodiment of the present invention, the fuel saver of the present invention with reference to Figs. The configuration is as follows.

One end of the discharge-side housing 10 is provided with a discharge nipple 11 so that the engine-side fuel pipe is fitted, and the fuel tank is located on the other side of the inlet-side housing 90 coupled with the discharge-side housing 10 by a conventional screwing means. Inlet nipple 91 is provided to be coupled to the fuel pipe connected with.

At each inner end of the discharge side housing 10 and the inlet side housing 90, a ring-shaped ring magnet 20 and a washer 21 having a size corresponding to the ring magnet 20, as shown in FIG. 2. And diffusers 30 and 31 formed of a plurality of blades are provided in symmetry with each other.

At this time, the inner surface of the discharge-side housing 10 is preferably curved so that the cross section is curved so that the inner diameter is gradually reduced toward the discharge nipple (11) side as shown in the curved form in FIG.

The prior art proposed by the present inventors has a straight shape, but when manufactured in a curved shape as in the present invention, the fuel diffused and discharged through the discharge-side diffuser 30 hits the reflective surface 12 and causes diffuse reflection. Fuel can be efficiently distributed over a large area.

Meanwhile, a cap 40, a sleeve 60, and a sleeve body are formed in each of the diffusion plates 30 and 31 of the housings 10 and 90 in which the discharge side housing 10 and the inlet side housing 90 are coupled. An assembly in which 80 is coupled to each other is incorporated.

First, the sleeve 60, the sleeve body 80 is coupled to the bottom, as a medium means for coupling the cap 40 to the top, that is, the spherical sleeve ball 50 in the fuel cylinder hole 61 is advanced It is provided to be possible, the lower portion of the fuel cylinder hole 61 is formed with a protruding nozzle portion 62 so that the sleeve ball 50 does not retreat any more, the lower portion of the nozzle portion 62 is curved inclined portion 63 On the other hand, the cap 40 having a plurality of discharge holes 41 is screwed to the outer circumferential surface of the fuel cylinder 61, the cap 40 is a sleeve ball 50 in the fuel cylinder 61 It has a structure to prevent the departure.

Here, the curved inclined portion 63 also, when the fuel that passes through the inside of the bushing 70 to be described later, like the curved portion 12 formed in the discharge side housing 10 is reflected while hitting the curved inclined portion 63, the fuel The fuel is further activated by the magnetic force of the ring magnet 20, while dispersing it efficiently over a large area.

The sleeve body 80 which is screwed under the sleeve 60 is alternately embedded in the inner fuel hole 81 with a plurality of ring magnets 20 and washers 21 as shown, wherein each ring The partition wall 82 protruding from the sleeve body 80 may be formed between the magnet 20 and the washer 21 so that these gaps may be defined by the partition wall 82. It is also possible to prevent the gap or flow of (21). Of course, the arrangement of the washer 21 and the magnet 21 is not limited to the order of the illustrated example.

The cylindrical bushing 70 is interpolated inside the magnetic material in which the plurality of ring magnets 20 and the washers 21 are alternately stacked.

The bushing 70 is provided with a spherical bushing ball 51 therein so that the bushing ball 51 can be moved in and out of the bushing 70, and the bushing ball 51 has the sleeve ( Retraction is prevented by the curved inclined portion 63 formed at 60, and retraction is prevented by the jaw 72 protruding inwardly from the other end of the bushing 70 at the time of retreat.

Therefore, the inner diameter of the bushing 70 is somewhat larger than the outer diameter of the bushing ball 51, the inner diameter of the jaw 72 is preferably smaller than the outer diameter of the bushing ball 51, where the bushing ( 70) The gap between the uneven surface 71 formed in the longitudinal direction on the inner surface and the bushing ball 51 can be appropriately designed depending on the type of internal combustion engine within the range of 0.05 to 0.2 mm.

At this time, the uneven surface 71 formed in the longitudinal direction of the bushing 70 allows the fuel blocked by the bushing ball 51 to pass through the uneven portion of the uneven surface 71. 71 is formed on the entire inner circumferential surface of the bushing 70. In the illustrated embodiment, unevenness is formed in the longitudinal direction of the bushing 70, but it is possible to form a vortex while extending the residence time of the fuel further. In order to ensure that the irregularities can be manufactured in the form of a spiral like a female thread.

The height of the unevenness is different depending on the type and displacement of the internal combustion engine, but it is preferable to be within the range of 0.1mm to 1.0mm. If the height of the unevenness is too low, the amount of fuel is supplied so that the fuel pump is overloaded. The fuel pump may be burned out. On the contrary, if the fuel pump is too high, there is a limit to atomizing the fuel, which is not suitable because the effect of the fuel saver is inferior.

When configured in this way, the number of the Gaussian of the ring magnets 20 according to the position or do not need to separately manage, assembling the size of the Gaussian, it is advantageous than the conditions of the prior art in terms of assembly and management.

On the other hand, the ring magnet 20 is generally treated with a metal coating such as nickel plating on the surface to improve the durability of the magnet, the metal coating layer is easily peeled off when exposed to fuel for a long time.

Thus, if the side surface of the ring magnet 20 is assembled using the washer 21 having the same size as the ring magnet 20, the metal coating layer is not directly exposed to the fuel by the washer 21, so durability Is improved.

FIG. 2 is a state diagram without stepping on the accelerator, and FIG. 3 is a longitudinal cross-sectional view showing the assembled state of the fuel saver according to the embodiment of the present invention.

Referring to Figures 2 and 3, the operation of the present invention will be described.

First, when the fuel saver of the present invention is installed on a fuel supply line of an automobile, the sleeve ball 50 is retracted by the magnetic force of the ring magnet 20 formed inside the sleeve body 80 to close the nozzle 62. do.

In this state, when the fuel pump is driven by driving the engine, fuel is introduced into the inlet housing 90 by the pumping force of the fuel pump, and the fuel introduced into the inlet housing 90 is a ring magnet. The bushing ball 51 formed in the inner surface of the bushing 70 after passing through the washer 21 and spreading and spreading primarily inside the inlet-side housing 90 through the inlet-side diffuser 31. It passes through between the concave and concave surface 71, and at this time, since the concave and convex surface 71 is formed over the entire inner circumferential surface of the bushing 70, the fuel is dispersed over the entire surface, and the fuel is also bushing ( 70) It is further activated by the magnetic force of the ring magnet 20 provided on the outer circumferential surface of the bushing 70 while passing through the inside.

When the dispersed and activated fuel reaches the nozzle part 62 of the sleeve 60, the bushing ball 51 opens the nozzle part 62 by the pumping pressure of the fuel, and the fuel is nozzle part 62. And atomized again while passing between the bushing ball 51 and supplied to the discharge side housing 10 through the plurality of discharge holes 41 formed in the cap 40, and then inside the discharge side housing 10, the discharge side diffuser 30. By diffusing again, it is possible to realize complete combustion of fuel in the combustion chamber.

What has been described so far is the idle state without the driver stepping on the accelerator.

However, when the driver steps on the accelerator for driving, a pressure difference is generated by the pressure of the fuel pump so that the bushing ball 51 moves in the fuel supply direction and the sleeve ball 50 also opens the nozzle part 62.

At this time, while the sleeve ball 50 closes a part of the discharge hole 61 formed in the cap 40 to reduce the fuel passage cross-sectional area, the pumping pressure of the fuel is further increased, and eventually, the discharge hole 61 of the cap 40. After passing through), fuel is quickly supplied to the combustion chamber. That is, more fuel is supplied to the combustion chamber side during the same time.

As described above, after the fuel refined by the bushing 70 passes through the discharge hole 61 of the cap 40, the diffuser 30 and the reflective surface 12 provided in the discharge side housing 10 are described. By the fuel is diffused and activated again by the fuel, it is possible to realize the complete combustion of the fuel in the combustion chamber (not shown).
