Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides an atomized or gaseous shield produced by a hollow rod with holes in a mixer, optionally located in the exhaust region of a vaporizer. The present invention relates to a fuel saving device and an operating device therefor.

Various types of fuel saving devices have been developed in the past. Each of these has two purposes. In other words, it is important to move cars efficiently and to prevent environmental pollution caused by harmful substances.

In fuel saving devices aimed at improving the combustion process in motors, the fuel droplets initially created in the carburetor (which are already mixed with the combustion air) are transformed by speed conversion and current transformation processes. The key point is to approach the ideal ratio in the combustion chamber with additional secondary air. If this is achieved, which is desired to be the optimum ratio for the combustion type and combustion rate, it will be possible to save fuel and at the same time minimize gaseous harmful substances by reducing the air-fuel mixture.

It is known that such an optimum state can be achieved by adjusting the amount of air supplied to the carburetor by the motor in accordance with the degree of pressure reduction. In this case, the amount of supplied air is controlled by the controller in accordance with the increase in the degree of pressure reduction (suppressed before the throttle valve).

It is already known that such a fuel saving device for atomized fuel can be realized by hollow ronds arranged in the mixing region. In this case, the mixer is arranged in the outlet region of the vaporizer, and a hollow rond with holes is made as a mixing nozzle (jet or orifice).

However, the above-mentioned devices have not yet reached the stage of being fully reliable. This is because the vaporized flow and the secondary air, which have not yet been sufficiently created, can be thoroughly mixed through the holes to achieve the best possible mixing condition. Although the flow rate of the gas mixture to be combusted requires very high mixing efficiency in a short time, the best solution to the above situation needs to be found.

The present invention solves the problem of obtaining this mixing efficiency at very high speeds and in a very short time in a small space by using specially shaped hollow rods (Steg) in the mixing zone. I left at the beginning.

The above problems can be solved according to the present invention.

The fuel saving device according to the invention can be applied to gaseous fuels as well as atomized (vaporized) liquid fuels. The invention makes use of a hollow rod with holes, which is arranged in the medium stream to be produced, optionally in the exhaust area of the vaporizer. The hollow rod is constructed as a mixing nozzle, a) with a constriction at its nozzle mouth, b) with a triangular part with a slit arranged in the mixing part, and C) with this triangular part. d) The entire mixing portion is disposed in the mixing area.

In a further embodiment of the invention, the axis of the hollow rod forms an angle of approximately 20° with respect to the throttle valve axis.

The hollow rod is roughly divided into halves with respect to the perpendicular to the hollow rod axis, with one half forming one slope and the other half forming the other slope. Purposeful. In the second case, the slopes are arranged at an angle to the direction of the medium flow, and the slits of one group of slits are arranged at an angle to the slits of the other group of slits. There is.

Further details of the invention are set out in the dependent claims.

Next, the present invention will be explained in more detail based on the embodiments shown in the drawings.

In FIGS. 1 to 4, a mixing region with a mixer (1η) according to the invention is shown; the mixer αη according to the invention is in the form of a hollow rod (1ω) with a sulin (111). In particular, it is clear from Fig. 4 that the hollow rod has a slope of 0.
The base of the triangle formed in that case is a semicircle.

With respect to the perpendicular to the hollow rod axis, the slope (IJl(1
A slit group a9.06) is arranged on 41. The slit groups (15) and (16) are arranged at an angle to each other, and the air supply pipe to the hollow rod (101 and its surrounding area forms a mixing chamber α mark.Hollow rod QO). suddenly tapers off at ff01 in front of the mixing chamber. ing. The flow velocity is therefore increased at this location.

FIG. 5 shows the mechanism of the mixing chamber. That is, the mixing chamber is connected to an air filter (1), a vaporizer (4), a power distribution device (40), and a specially configured secondary air controller (50). Air is then sucked through the air filter @),
The filtered air is directed into a vaporizer. vaporizer (to)
A normal throttle valve (311) is disposed inside.The air filter (2) is connected to the exhaust conduit side λ for the crank chamber.

Conduit c! 1) and the intake conduit for the controller (50) are connected by a conduit. From the vaporizer (@), it is led via a vacuum conduit (2) to a controller (4) and via a T-, a fitting and another vacuum conduit (41) to a power distribution device (40).

As the piston changes over time, the pressure inside the conduit (21) becomes reduced when the piston in the engine chamber is on the downward stroke, and becomes overpressure when the piston is on the upward stroke. In the present invention, by utilizing this phenomenon,
A bypass is made in the conduit (2I) for secondary air exhaust. In other words, the conduit is that. As a result, the conduit (211) and the controller are directly connected via the intake conduit (23) that connects the filter (20) and the controller Kasumi. ) and (2) are also small.

The installation of this connecting conduit will yield greater results than expected. Experiments with Stroen vehicles have shown that fuel savings of 10 to 20% can be achieved on average.

Although it is surprising, as a secondary result, the emission of harmful substances has decreased by 30% for NOx, and 45% for CH.
It was observed that CO was reduced by 70 inches.

This surprising number can be explained by the fact that the aerodynamically pulsating air flow between the crankcase and the conduit (21) contains atomized oil vapor.

Conventionally, there has been a phenomenon in which the filter part becomes contaminated with oil, but this can also be explained in the same way as above.

In the present invention, it has been confirmed that the installation of the connecting conduit (24) causes no or almost no precipitation of mist oil. This indicates that a significant amount of atomized oil is being directed into the intake conduit (22) to the controller (50) by the example connecting conduit. The air mixture thus obtained is then drawn into the mixer (1η), i.e. the initially produced vaporized fuel is passed through the connecting conduit (24) with the clean air drawn from the p-filter (20).
), a high-performance fuel mixture is obtained which is capable of very good combustion.

- As shown in Figures 6 to 8, the controller (50) for the secondary air includes bypass control (51), no-load control (521), pressure adjustment for the control piston, and control. A suction pipe for the device and a discharge pipe for the hollow rod are provided.The cross section of the suction pipe is triangular as shown by Q56 in the drawing.

The piston is a sliding piston M. The cap I01 is further provided with a lubricant/membrane chamber (57). film(
58) is spring loaded.

The function of the mixer (1η) is characterized by a dual action in two directions, in view of the pneumatic action in the mixing chamber (18).

Both channels encounter gas flowing in one after another. The highest turbulence therefore occurs in very narrow spaces. This high turbulence allows the device according to the invention to function as an excellent mixer for gas production. Conventional mixing chambers, at their state of the art, have not reached the level of producing an ideal gas-air mixture. The introduction of the mixer according to the invention is therefore a notable technical improvement in terms of fuel savings. However, it is noteworthy that combustion gas can be consumed very effectively not only from the viewpoint of reducing harmful substances but also from the viewpoint of reducing harmful substances.

Further embodiments are shown in FIGS. 1-19. This is the hollow rod 00) and the controller (50
).

In this case, the slit group (nozzle group - hollow rod 00)
The position of I5) and (16) on the slope relative to the longitudinal axis (12) of the nozzle group-hollow rod has been improved so that they are no longer parallel to each other but at an angle. Experiments have shown that this arrangement according to the invention significantly increases the mixing efficiency.

ing.

In addition, the nozzle group - a small diameter insert (
19) is arranged, which allows the gas mixture to pass through the slit group (151, (in the stage before IGI)
It is considered to be of excellent quality. Finally, a screw hole (101) is provided at the tip of the nozzle group-hollow rod (10), which facilitates installation and removal. That is, as is clear from FIG. 14, by tightening the fixing screw (102), the position of the nozzle group (hollow rod 00) is firmly fixed;
By loosening the hollow rod 02), the hollow rod can be removed very easily on a case-by-case basis, for example for servicing.

Improvements to the controller (50) include a stop or stroke limit (551) under pressure from the piston range and support spring (573).

This fixes the screw (551).

The function of the sliding piston 155) is improved by the arrangement of a space limiter in the intake hole (59). This spacer (561) is fixedly placed in the intake air (59). (561) is the cylindrical upper part (5
62) and a lower part (563) forming an acute angle.

Its open cross section (564) then runs parallel to the axis of the intake hole (59), which has a circular cross section surrounding it.

For all functions of the controller (50), the sliding piston and the triangular spacer interact together.

The triangular space acts to prevent motor intake or choking during complete adjustment, and to slowly feed air from the controller in the exhaust direction (591).

For the purpose of equilibrium, a hole (521) with a relatively small diameter is provided in the upper membrane chamber η, while an intake hole (575) is provided in the lower space (574) of the membrane chamber. bypass control device (51) for any type of motor.
