The present invention relates to a method for producing a substitute fuel composition, characterized by stirring at a rotational speed of 50 to 200 r, p, m, and storing the product at room temperature for 48 to 72 hours.

Herein, the volume % indicated for each mixture and each composition component indicates their volume % relative to the total amount of the substitute fuel composition of the present invention.

The fuel of the present invention can be used with the same efficiency as known gasoline, yet has no adverse effects on internal combustion engines.

Since fuel raw materials are easily available domestically, there is no need to import fuel from other countries.

Furthermore, since the fuel of the present invention does not generate smoke during combustion, environmental pollution can be prevented.

Various proposals have been made to create alternative fuels such as the fuel of the present invention.

However, since all of these alternative fuels are derived from crude oil or existing gasoline itself, they have many drawbacks.

In other words, known synthetic fuels made from commercially available gasoline have similar chemical and physical properties to the raw gasoline.

That is, an object of the present invention is to provide a new fuel oil that does not have the above-mentioned drawbacks.

For reference, the standards for commercially available gasoline are shown below.

(1) The above gasoline cannot be washed, but 5/10020
When gasoline in the range of m9/100ml is washed with the above solvent, it reaches a practical level of 5cm/roomz.

(2) Alkyl chains other than tetraethyl lead cannot be used.

The amount of alkyl chains, expressed in terms of metallic lead, may correspond to the amount of lead in tetraethyl.

The fuel must generally be applied in an inert manner to the metal materials of the equipment and/or equipment in which it is used, and must not remain stationary during movement and pumping.

Also, troublesome things such as vaporization and saturation due to vapor pressure must not occur.

It has excellent ignitability and combustibility when starting and operating an internal combustion engine.

On the other hand, if the internal combustion engine is stopped☆☆, ignition will not continue due to residual pressure.

As mentioned above, the alternative fuels that have been proposed so far are worthless from an economic point of view.

These fuels cannot be manufactured on a large scale, and they do not solve problems such as smoke generation and pollution.

(3) Tetraethyl lead or other alkyl chains have a characteristic that may cause the fuel to be colored to indicate that it contains a lead component.

This has nothing to do with octane rating.

For reference, the characteristics of gasoline according to KSM2612 147812-1 are shown below.

On the other hand, it has been found that adding benzene to gasoline improves the ignition efficiency of gasoline.

The physical properties of benzene are as follows.

As previously mentioned, the substitute fuel of the present invention is prepared by diluting a mixture of methanol, benzene, ether, texturin, and histearic acid, and then combining the diluted mixture with 5.0%
It can be obtained by mixing with a combustion accelerator.

The combined vapor pressure of methanol/water vapor/liquid thus constituted is described below.

Therefore, according to the present invention, 30 to 2
In order to obtain a boiling point of 00°C, the raw materials must be mixed in a predetermined ratio.

In order to solve the problems described at the beginning of this specification, the mixing ratio is the most important condition.

When methanol and water are mixed in the proper proportions, benzene acts as an accelerator.

Therefore, although the mixture exhibits some immiscibility,
It has excellent ignition power.

Furthermore, the amount of heat is insufficient because it is difficult to control the steam pressure.

However, when benzene is added and mixed with ether (R-0-R/) and acetic acid compound (R-COOH), the mixture becomes highly flammable and combustible.

In other words, when gasoline is used in an internal combustion engine, it combines with air to form a gas mixture, and when this gas mixture is compressed, ignited, and exploded, the piston moves back and forth.

In this way, an internal combustion engine operates in a suction/compression/explosion/exhaust cycle.

Gasoline, as a compound consisting of carbon and hydrogen, can be obtained from crude oil and/or coal, which has a large calorific value (11000-11500 cal/kg) and a low specific gravity (0.67-0.0. 76).

Methanol (flash point 15.6°C1b, p, 64.
5°C), a composition consisting of benzene, ether, xylene and a combustion promoter exhibits similar properties.

When burning regular gasoline, a constant supply of oxygen (air) is required to create good combustion conditions.

However, since the fuel of the present invention generates oxygen itself during combustion, the air used with this fuel becomes excessive, reducing power output and ignition spark.

This is because, when compared to gasoline, the fuel of the present invention has
This is because there is no need to waste air.

In the present invention, the functions performed by each component are as follows.

Methanol is the main component of fuel, and it burns rapidly inside the cylinder, causing an explosion.

Water and dextrin increase the body surface area of fuel particles.

Benzene promotes fuel detonation, and stearic acid and acetone promote fuel combustion.

Dimethyl ether increases the flammability and flammability of the fuel.

The surfactant cleans the vaporizer valve.

Examples of alternative fuel compositions according to the invention are shown below.
