Description

A METHOD OF USING AN EMERGENCY FUEL IN AN INTERNAL COMBUSTION ENGINE}

The problem of "gas depletion" is as old as using gasoline to power electric vehicles such as cars and ships. This has long been a problem and no one has ever provided a safe and practical answer. This problem did not provide a solution because gasoline generally contains some butane and pentane, giving a flash point of -40 ° to -50 ° F. The butanes and pentanes are necessary for the cold motor to be easily started. This means that the spilled gasoline quickly vaporizes to form explosive vapors that can be ignited by the flame. As a result, it is quite dangerous for storing or transporting gasoline in containers in automobiles or other means of transport. In fact, many states make it illegal to store gasoline containers in the trunk of a car. However, the alternative fuel does not contain butane or pentane and can be safely stored in an automobile or other transport means. In addition, it is safe and does not degrade quality even after long-term storage for more than one year.

Most prior applicants have been interested in improving the combustibility of gasoline, enabling fuel use at lower temperatures, and improving the octane rate for faster start-up and faster speeds. This is done by adding alcohols, ketones and ethers to gasoline and petroleum fuel products. The following patents focus on this goal:

These prior art do not relate to the use of alternative fuels for internal combustion engines that are safe to store in vehicle means.

The only prior art for emergency alternative fuels was the 1970 "RESCUE" by Cristy of Pittsburgh, MA. This product is commercialized under the name "This product has already lost its market transactions and has not been commercially successful due to the difficulty of starting the engine, smoke and odors when used. Furthermore," RESCUE Commercialized containers do not have blowpipes and use an auxiliary funnel to inject the product into the gas tank.

Therefore, there is a need for emergency alternative fuels used in containers that are safe, operate efficiently in internal combustion engines and can be used without auxiliary components.

The present invention relates to an alternative gasoline motor fuel that is convenient to use in emergency situations where regular fuel is consumed and can be stored safely over a long period of time. The invention also includes means for storing the fuel in a container having certain features.

The object of the present invention is as follows:

end. Alternative fuels that can be safely stored in most vehicles.

I. Alternative fuel with flash point of 5 ° F or higher. Even at a flash point of 5 ° F., the fuel is safer than gasoline. Increasing the flash point above 5 ° F makes the fuel safer. At the same time, studies with test motors show that starting the motor becomes more difficult at higher flash points.

All. Alternative fuel that can be added to a tank of "gas depleted" vehicle means and can be started if the motor of the vehicle means cools.

la. Alternative fuels will work flexibly in most internal combustion engines.

hemp. A container for said alternative fuel having a neck or an expandable blowpipe for pressing said metal shield to open near said vehicle gas tank opening to allow said alternative fuel to be injected into said fuel tank. The neck or outlet pipe is small in diameter to fit into the lead-free gas tank inlet.

bar. Means for closing said container, said closure device being opened and then again said closure device made unused. This makes it impossible for the user to empty the container and fill it with storage gasoline in the vehicle.

four. Alternative fuels, including one or more oxygen-containing solvents, which, through sufficient dissolution, dissolve and remove rubber deposits in tanks and fuel systems to extend the range of use of ordinary gasoline.

According to the above object according to the invention, a disposable plastic container comprising an emergency alternative fuel for an internal combustion engine is disclosed. The container has an outlet and the outlet is sealed with a removable seal. The container cannot be reused for storage after the seal is removed. The container is formed with a material that does not chemically react with the alternative fuel and which does not react.

The alternative fuel may be a mineral spirit, a mixture of n-butanol and amyl alcohol isomers, 1-pentanol or a mixture of 0-100% oxygenated solvent and 0-100% mineral spirit. The alternative fuel is preferably free of olefins. The olefin may be of a minimum amount if an oxygenated solvent such as an alcohol is present in the fuel to dissolve the rubber formed from the olefin.

It is another object of the present invention will be very clearly understood by those skilled in the art in the following description, which will be illustrated and described through preferred embodiments of the present invention. Briefly, for example, the present invention will next be described in the present disclosure, which will be apparent to the person skilled in the art on the following experiment, or which can be seen through practice of the present invention. Accordingly, the drawings and disclosure are to be regarded as illustrative in nature and should not be construed as limiting.

The emergency alternative fuel disclosed in the present invention provides a method for safely coping with the long-standing problem of "gas depletion". The supply of fuel can be safely stored in the vehicle means and can be used successfully in case of emergency.

In the prior art, gasoline, which is very dangerous to store in automobiles or other vehicle means, was the only choice. However, this alternative fuel differs from such gasoline in several ways. Components that make gasoline dangerous for storage are butane, pentane and similar light hydrocarbons with low boiling points. They are removed from the alternative fuel. At the same time, the rather heavy components are balanced to each other and are within the boiling range of gasoline, which allows them to work smoothly in the internal combustion engine.

One of the factors for fuel safety is the flash point of the fuel. For optimum compromise between stability and ease of starting versus flash point, the preferred flash point is 104 ° to 110 ° F. This range provides very little safety above 100 degrees Fahrenheit, below which the US Department of Transportation classifies substances as "flammable". If the flash point is above 100 ° F, the DOT classifies the material as "combustible" and the safety rules are less stringent. Oxygenated solvents as well as a wide variety of mineral spirits, petroleum distillates and petrochemicals can be used if they fall within the desired flash point parameters and meet different requirements. All flash points mentioned below are those specified by ASTM D56, closed cup. Three typical typical mineral spirits are:

Mineral Spirit A B C

The paraffins, naphthenes and aromatic compounds are hydrocarbons containing 9 to 12 carbon atoms in each molecule. The following list lists the oxygenated solvents considered in connection with the formulas of the present invention.

Material Flash Point F Evaporation Rate Boiling Point F

1.1-pentanol 119 0.18 280

Internal combustion engines work well with only 1-pentanol or with 1-pentanol mixed with mineral spirits. It does not generate odorous and smoky emissions. It is a solvent for rubber formed in gasoline and will absorb moisture in the fuel system. When mixed with mineral spirits, the price is reasonable. When 25% of 1-pentanol is mixed with 75% of mineral spirits having a flash point of 108 ° F., the mixture has a flash point of 102 ° F. It has no sulfur and is stable for long term storage. It does not attack High Density Polyethylene (HDPE) containers.

2. Primary Amyl Alcohol 113 0.20 272

15. Others:

end. Many esters such as hexyl acetate, pentyl propionate, butyl propionate and the like can be contemplated but are expensive and there are doubts regarding peroxide formation.

I. Many derivatives of ethylene glycol and propylene glycol have the appropriate flash point and evaporation rate. However, they are all easy to form poisoning peroxides and are excluded for this reason.

All. Derivatives of furan, such as furperyl alcohol, may be available. However, they are all unsaturated molecules that become unstable upon contact with air, as is known, or are too expensive.

la. A great number of esotheric materials can be used but can be expensive or have other disadvantages. Some of these are:

Propionic acid

Acetic acid

Formic acid

Various aliphatic amines

Dibutyl carbonate

N-methyl ethylene diamine

Tributyl phosphine

Variety of Aliphatic Nightlit

These may be used alone or in combination with mineral spirits or alcohols.

Many other solvents, chemicals and synthetic petrochemicals can be used as long as all fuel conditions can be met. Some of these include alkyl benzenes and alkylates obtained by olefin paraffins and isoparaffin reactions. In addition to higher analogs, oxygenated fuels such as methyl tertiary butyl ether, tertiary amyl methyl ether may also be included. Often, certain chemicals are produced by mixing two or more substances. The desired end product has a lower flash point than desired for this alternative fuel. However, after the desired end product is evaporated, the base product may have a flash point that makes it useful as an alternative fuel.

The flash point of the alternative fuel is sufficiently high that the combustion match thrust in the fuel is extinguished, preventing the fuel from igniting. In order to move smoothly, the fuel must have the same or more octane number than regular gasoline. This is generally 86 to 88. It must also be in the gasoline distillation range with a distillation "end point" not higher than 450 ° F. Very many petroleum distillates, such as mineral spirits or standard solvents, satisfy both requirements. Naphthenes, aromatics and isoparaffins help to increase the octane number. Normal paraffins reduce octane number but are not superior except for crude oil, which never cracks in "direct" mineral spirits. Most mineral spirits do not fall into this category. On the other hand, many common chemicals and solvents, such as cyclohexanone, ethyl butyl ketone and diacetone alcohol, have good octane numbers.

Another difference between the emergency alternative fuel of the present invention and gasoline is the presence of olefins. Gasoline generally forms rubber and contains olefins that degrade the gasoline after extended periods of time. The olefin can be easily removed from the hydrocarbon by hydrogenation. Many hydrotreated mineral spirits are available on the market. Their olefin content is virtually zero, allowing for excellent stability in long term storage. The olefin may be irrelevant in small amounts if there is an alcohol that dissolves the rubber formed therefrom. In addition, most synthetic petrochemicals are basically free of olefins. Hydrocarbons present in most olefin-free mineral spirits are quite stable and do not form unstable peroxides. The same holds true for cyclohexanone and some other oxygenated solvents. On the other hand, chemicals such as ethylene glycol monomethyl ether may form unstable peroxides when stored in contact with oxygen. These unstable peroxides may decompose dangerously at temperatures in the trunk of a car on hot days.

The emergency alternative fuel must also have a low content of aromatic components to be able to prevent or reduce the production of combustible and smoky combustion products. Aromatic compounds are harmful to internal combustion engines and are also undesirable for consumer approval. It is preferable that content of the aromatic compound of the said alternative fuel is 15% or less in volume.

It is desirable to add oxygenated solvent to the alternative fuel to produce a fuel that can remove rubber from the system while the fuel system performs its primary function. Many oxygenated chemicals such as alcohols, esters, ketones and ethers can be used for this purpose unless they form the following situation:

end. Situations where the flash point is lowered to an undesirable level.

I. A situation in which the usability of the alternative fuel is affected by interacting with the container being used to damage the container or to extract material from the container.

All. Situations that form unstable peroxides. Many oxygenated chemicals cannot be used because they form unstable peroxides that can be dangerous during prolonged storage upon contact with air. Some of these chemicals are as follows: isobutyl isobutylate, ethyl 3-ethoxypropionate, propylene glycol monomethyl ether acetate, ethylene glycol monomethyl ether, propylene glycol mono teshiryyl butyl ether and the like.

la. Situations in which carcinogenic risks exist, as in the case of benzene and other substances.

In some cases, the oxygenated solvent can be used as an alternative fuel in itself without mixing with the mineral spirits. One such solvent is 1-pentanol and the other is a mixture of isomers of n-butanol and amyl alcohol.

Plastics such as high density polyethylene and polyethylene terephthalate or other plastics may be selected as the building material of the container. The addition of aggressive solvents, such as ketones or ethers, to alternative fuels makes it important to select plastic and oxygenated solvents that do not cause chemical reactions but do not interact with each other. Metal containers may be used but have the disadvantage of lacking some of the advantages of plastic containers.

Referring now to FIGS. 1 to 8, the container 10 for storing the emergency alternative fuel 11 preferably has a handle 12 so that a user can move the container and hold it when injecting it. Preferably, the handle 12 is an integral part of the container 10. The container 10 forms an outlet 14 through which the fuel 11 can be injected. A removable seal 16 is located on the opening of the outlet 14 to retain the fuel 11 in the container 10, prevent evaporation of the fuel 11, and provide proof of change. . In one embodiment, the seal 16 is a brittle layer, such as a foil, which is secured surrounding the outer circumferential surface of the outlet 14 by adhesive, ultrasonic sealing or other means. The outlet 14 also includes a threaded outwardly extending neck. An interactive threaded cap 18 is formed on the distal end of the outlet 14 such that the brittle yarn 16 lies between the cap 18 and the outlet 14 and the seal 16 ) To protect against unexpected damage or rupture. The cap 18 has at least one opening 20 formed through the top surface of the cap 18. The opening 20 should be large enough to protect the seal 16 from damage, but should be large enough to allow liquid and vapor to pass through the opening 20. The purpose of the use of the cap 18 with at least one opening 20 is to remove the seal 16 and to store fuel such as gasoline or other flame-producing materials after use of the emergency alternative fuel 11. In order to prevent the reuse of the container 10. Without such a closure, some consumers will open the container, use the alternative fuel, and then fill the container with gasoline for future use. This can be very dangerous.

In another preferred embodiment (FIG. 9), the seal 16 covers the outlet 14 and includes a band 22 integrally attached to the cover. The band extends entirely around the outlet and keeps the seal 16 on the outlet 14. The band 22 forms a pull tab 24. Pulling the pull tab 24 separates the band 22 from the cover to remove the cover so that the alternative fuel can be used. When the cover and the band 22 are secured to the outlet 14, the replacement fuel 11 is retained in the container 10 during at least one year of storage. After the seal 16 is removed, the cover cannot be reattached to the outlet so that the container 10 cannot be reused for storage of gasoline and similar fuels.

In another embodiment as shown in FIGS. 10-12, the seal 16 is a threaded cap 28 with threads that interact with threads on the outlet 14. The upper portion of the cap 28 has a prestressed ridge 30 formed therein. The prestressed ridge 30 surrounds the outer circumferential surface of the cap and also delimits a limited area of the upper end of the cap 28. In the region bounded by the prestress ridge 30, a pull ring 32 is attached on top of the cap 28. As a result, the cap 28 closes and seals the outlet 14 of the container 10 when the container 10 with the alternative fuel 11 therein is stored for at least one year. . If the alternative fuel 11 is to be used, the user grasps the pull ring 32 and pulls it out of the cap 28. The entire area of the cap 28 attached to the pull ring 32 in the area delimited by the prestress ridge 30 is separated from the cap 28 leaving an opening in the cap 28. do. The opening has a diameter large enough to allow the spout pipe 26 to extend through the opening and the alternative fuel may come out of the container 10. The container with the opening in the cap 28 cannot already be used for fuel storage and the container 10 is used once and corresponds to a consumable.

Other types of removable seals may be used so long as they have alternative fuel stored in the container for at least one year. The seal is made of a material that does not chemically react with the alternative fuel and the seal cannot be used to seal the container for reuse.

In addition, the container 10 is provided with a blowing means 26 to smoothly exit the alternative fuel 11 from the container 10. This eliminates the need for the long neck funnel used to inject the alternative fuel into the fuel tank. Such funnels are difficult to find and cumbersome to store. In emergency situations, the long neck funnel is not easy to use. The container 10 has a ejection means 26 formed integrally with the outlet 14 located at the distal end of the container body. In a preferred embodiment, the ejecting means 26 is a separate member retained in the container 10 and extends outwardly from the outlet 14 after the seal 16 is removed. The blowing means 26 has a length sufficient to open by pressing the metal shield in the inlet of the automobile gas tank and the diameter of the blowing means 26 is formed small enough to fit the inlet of the unleaded gas tank.

The container 10 is made to a desired size. One quart of capacity is appropriate for motorcycles and similar vehicle means, one gallon of capacity for a typical vehicle, and five gallons for trucks and ships.

For small motor boats and motorcycles, alternative fuels will mostly start warm motors and drive them flexibly. Such motors are almost always warm when the gas is exhausted and will be able to start the motor well if an alternative fuel is used immediately. If the motor is cold and does not start, it is necessary to use a "starter" such as butane spray in the carburetor to start the motor.

It also works well with alternative fuels. Although starting fluid is required, it is quite easy to use in small motors.

Automobiles are particularly different in that they have a widely used fuel-injection system. However, for cars, unexpected surprises occur. If the car is "out of gas" and the motor is stopped, there is still gasoline remaining in the tank and fuel system. When the replacement fuel is replenished, it is mixed with its remaining gasoline, providing enough butane and pentane to drive a cold motor.

The alternative fuel cannot be used to replace gasoline on a long term basis because it lacks butane and pentane necessary to start a cold motor under normal conditions. For emergency use in the short term, the alternative fuel is quite satisfactory.

To illustrate the manner in which the invention is practiced, the following examples are given. However, these examples are for illustrative purposes and should be understood so that the present invention is not to be considered as being limited to any particular material or condition disclosed herein. Or unless otherwise indicated, parts disclosed in the above examples correspond to parts of the whole.

First embodiment

This example shows the sole use of a mineral spirit type petroleum distillate. This material has an ASTM D56 flash point of 109 ° F and an ASTM D86 distillation range of 324 ° F to 381 ° F. The composition is 40% paraffin, 45% naphthene and 15.0% aromatic compound. The olefin content is zero. Cold test motors do not start with this material, but once the test motor warms up, it is easily started and flexibly driven using the material.

Second embodiment

This example shows the use of a mixture of oxygenated solvent and mineral spirits. The mineral spirit has a flash point of 106 ° F. and a boiling range of 319 ° F. to 383 ° F. The oxygenated solvent is methyl isobutyl carbinol having a flash point of 103 ° F. and a boiling point of 269 ° F. The mixing of the two materials is made using 60% of the mineral spirits and 40% of the carbinol. The mixture of the two materials has a flash point of 94 ° F. The olefin content is zero. Cold test motors do not start with the mixture, but after the test motor warms up, it is easily started and flexibly driven using the mixture. The mixture performs a visible cleaning action in the gas tank, such as removing some of the rubber precipitate.

Third embodiment

This example shows the use of a mixture of ketones and mineral spirits. The mineral spirit has a flash point of 109 ° F and a distillation range of 324 ° F to 381 ° F. The ketone is a cyclohexanone having a flash point of 116 ° F. and a boiling point of 312 ° F. The mixture is made of a 50 to 50 mixture of the mineral spirits and the ketones. The mixture has a flash point of 109 ° F. and the olefin content is zero. Cold test motors do not start with the mixture, but after the test motor warms up, it is easily started and flexibly driven using the mixture.

Fourth embodiment

This example shows an alternative fuel that is only an oxygenated solvent. n-butanol has a flash point of 98 ° F. and mixed isomers of amyl alcohol have a flash point of 113 ° F. Mixtures of mixed isomers of 50% n-butanol and 50% amyl alcohol have a flash point of 104 ° F. classified as "combustible" materials. This mixture works better than other mixtures due to its higher volatility of n-butanol, but is more expensive. It does not attack HDPE containers and is stable during storage. The high oxygen content results in better exhaust capacity compared to mixtures with mineral spirits. Cold test motors do not start with the mixture, but after the test motor warms up, they are easily started and run flexibly.

Fifth Embodiment

This example shows the use of mixed isomers of single alcohol, amyl alcohol. The material has a flash point of 113 ° F. Cold test motors do not start with the material, but after the test motor warms up, they are easily started and run flexibly.

Sixth embodiment

This example shows the use of mineral spirits with a flash point of 108 ° F. alone. Boiling ranges range from 320 ° F. to 372 ° F. The composite is as follows:

Paraffin 46.6%

Naphthene 53.3%

It does not contain olefins that can form rubber during storage. Without alcohol, mineral spirits will not act as a solvent to remove rubber from the fuel system. The mineral spirit does not start the cold test motor, but after the test motor warms up, it is easily started and flexibly driven.

Seventh embodiment

This example shows the use of a mixture of mixed isomers of 75% mineral spirit and 25% amyl alcohol shown in the sixth example. The mixture has a flash point of 102 ° F. Cold test motors do not start with the mixture, but after the test motor warms up, they are easily started and run flexibly.

Eighth embodiment

This example shows the use of a mixture of 75% mineral spirit and 25% cyclohexanone having a flash point of 111 ° F. and a boiling point of 314 ° F. shown in the sixth example. The mixture has a flash point of 101 ° F. The cold test motor does not start with the mixture, but after the test motor warms up, it starts and runs flexibly.

9th embodiment

This example shows the use of mineral spirits containing some olefin and mixed with alcohol. Olefins are considered a potential problem in materials that require long-term storage, by oxidizing them to form rubbers that foul fuel systems. However, the mixture of this example will contain an alcohol that acts as a solvent for the rubber formed so that the rubber will not dirty the fuel system. For maximum long term storage, the olefin content should be minimal, even if alcohol or other oxygenated solvent is present. The content of the olefin in the final mixture should not exceed 50%, preferably 5% or less. In this example, the mineral spirits used have the following characteristics:

Flash point 125 ℉

Initial boiling point 346 ℉

Dry Point 390 ℉

composite:

Aliphatic Hydrocarbon 96%

Olefin 4%

Aromatic Compounds ---

100% in total

The following mixture is prepared:

65% of mineral spirits

n-butanol 5%

Amyl alcohol, mixed isomer 30%

100% in total

The mixture has a flash point of 104 ° F. The cold test motor does not start with the mixture, but after the test motor warms up, it is easily started and flexibly driven.

Although the alternative fuel does not drive the cold test motor in the above embodiments, the alternative fuel will drive the engine with the remaining gasoline in the fuel tank. As mentioned above, the alternative fuel contains no butane or pentane, but the remaining gasoline has a low flash point and allows a sufficient amount of these materials to start the engine. After the engine is started, it will continue to operate using the alternative fuel of the present invention.

Obviously, many other modifications may be made without departing from the basic scope of the invention. Thus, it will be understood by those skilled in the art within the scope of the appended claims, and the invention may be practiced otherwise than as specifically described herein.
