Definitions
- the present invention relates to a gasoline composition and its use, particularly, in combustion engines.
- Spark initiated internal combustion gasoline engines require fuel of a minimum octane level which depends upon the design of the engine. Petroleum refineries are constantly faced with the challenge of continually improving their products to meet increasingly severe governmental efficiency and emission requirements, and consumers' desires for enhanced performance. For example, in producing a fuel suitable for use in an internal combustion engine, petroleum producers blend a plurality of hydrocarbon containing streams to produce a product that will meet governmental combustion emission regulations and the engine manufacturers performance fuel criteria, such as research octane number (RON). Similarly, engine manufacturers conventionally design spark ignition type internal combustion engines around the properties of the fuel. For example, engine manufacturers endeavor to inhibit to the maximum extent possible the phenomenon of auto-ignition which typically results in knocking and, potentially engine damage, when a fuel with insufficient knock-resistance is combusted in the engine.
- a gasoline composition comprising (a) a major amount of a mixture of hydrocarbons in the gasoline boiling range and (b) a minor amount of at least one hydrocarbon having 5 to 12 carbon atoms and containing at least one cyclopropyl group and at least one acetylenic group.
- the present invention provides a method of improving the flame speed of a gasoline which comprises adding to a major portion of a gasoline mixture, minor amount of the additive described above.
- the present invention provides a method for operating a spark ignition engine which comprises burning in said engine such fuel composition described above.
- FIG. 1 represents the Schlieren images of single combustion event 30 ms after ignition of Base Fuel-1 plus 20% Cyclopropylacetylene.
- FIG. 2 represents the Schlieren images of single combustion event 30 ms after ignition of Base Fuel-1 only.
- FIG. 3 represents improvement in Hyundai Acceleration Performance of the Faster Flame Speed fuel blends versus Base Fuel-2 (reference fuel); all additive concentrations in ppmw.
- flame speed is the measured rate of expansion of the flame front, generally measured in meters/second (m/s).
- flame speed depends on gas pressure, temperature, and density change as a result of changes in volume due to piston motion (see Internal Combustion Engine Fundamentals, John B. Heywood. McGraw-Hill Book Co., 1988).
- rate of expansion of the flame front can also be measured by the increase in the pressure.
- Early pressure rise after spark (at 0 seconds) is also a measure of high burning velocity.
- the gasoline composition of the present invention contains component (b) of at least one hydrocarbon having 5 to 12 carbon atoms and containing at least one cyclopropyl group and at least one acetylenic group.
- acetylenic group refers to unsaturated hydrocarbons that have carbon atoms in chains linked by one or more triple bonds.
- the component (b) can be a compound having the formula:
- n is an integer from 0 to 7;
- R 1 to R 6 are independently hydrogen, alkyl group having 1 to 7 carbon atoms, alkenyl group having 1 to 7 carbon atoms, alkynyl group having 1 to 7 carbon atoms, cyclic group having 1 to 7 carbon atome, with the proviso that the total number of carbon atoms in the compound are from 5 to 12.
- n is an integer from 0 to 5, more preferably 0 to 3.
- R 1 to R 6 are independently hydrogen, alkyl group having 1 to 5, more preferably 1 to 3 carbon atoms, with the proviso that the total number of carbon atoms in the compound are from 5 to 12.
- cyclopropylacetylene can be prepared by chlorination of acetylcyclopropane with PCl 5 in the presence of an org. base in a chlorinated hydrocarbon with dehydrochlorination of the mixt. of alpha,-alpha dichlorocyclopropane and alpha-chlorovinylcyclopropane (with base at reflux in a solvent) and simultaneous distillation.
- Cyclopropyl Cyanide can be prepared by the reaction of sodium amide with chlorobutyronitrile (Organic Syntheses, Volume 3, page 223. John Wiley & Sons, Inc. Submitted by M. J. Schlatter and checked by R. L.shriner and Chris Best). Other methods can be used to prepare the cyclopropyl group-containing acetylenic compounds useful in the invention as are known to one who is skilled in the art of organic synthesis.
- the preferred cyclopropyl group-containing acetylenic compounds maybe, for example, cyclopropyl acetylene; 1-cyclopropyl-1-propyne; 1-cyclopropyl-2-propyne; 1-methyl-1-ethynyl-cyclopropane; 2-methyl-1-ethynyl-cyclopropane; 1,1-(3-methylene-1-propyne-1,3-diyl)bis-; 1,1-bicyclopropyl, 2,2-diethynyl-; 1-cyclopropylpenta-1,3-diyne; cyclopropane, 1,1-(1,3-butadiyne-1,4-diyl)bis-; cyclopropane, 1,1-(3-methyl-1-propyne-1,3-diyl)bis-; and 1,4-dicyclopropylbuta-1,3-diyne.
- the fuel composition of the present invention comprises a major amount of a mixture of hydrocarbons in the gasoline boiling range and a minor amount of component (b).
- component (b) means less than 50% by weight of the total fuel composition, preferably less than about 30% by weight of the total fuel composition. However, the term “minor amount” will contain at least some amount, preferably at least 0.001% by weight of the total fuel composition.
- An effective amount of one or more compounds of component (b), more particularly Formula I, are introduced into the combustion zone of the engine in a variety of ways to improve flame speed.
- a preferred method is to add a minor amount of one or more compounds of component (b) to the fuel.
- one or more compounds of component (b) may be added directly to the fuel or blended with one or more carriers to form an additive concentrate which may then be added at a later date to the fuel.
- each compound of component (b) used will depend on the particular variation of Formula I used, the engine, the fuel, and the presence or absence of carriers and additional detergents. Generally, each compound of component (b) is added in an amount up to about 20% by weight, especially from about 0.005% by weight, more preferably from about 0.05% by weight, even more preferably from about 0.5% by weight, most preferably from about 1% by weight, based on the total weight of the fuel composition.

- Preferred are gasoline mixtures having a saturated hydrocarbon content ranging from about 40% to about 80% by volume, an olefinic hydrocarbon content from 0% to about 30% by volume and an aromatic hydrocarbon content from about 10% to about 60% by volume.
- the base fuel is derived from straight run gasoline, polymer gasoline, natural gasoline, dimer and trimerized olefins, synthetically produced aromatic hydrocarbon mixtures, or from catalytically cracked or thermally cracked petroleum stocks, and mixtures of these.
- the hydrocarbon composition and octane level of the base fuel are not critical.
- the octane level, (R+M)/2, will generally be above about 85.
- Any conventional motor fuel base can be employed in the practice of the present invention.
- hydrocarbons in the gasoline can be replaced by up to a substantial amount of conventional alcohols or ethers, conventionally known for use in fuels.
- the base fuels are desirably substantially free of water since water could impede a smooth combustion.
- the word major amount is used herein because the amount of hydrocarbons in the gasoline boiling range is often 50 weight or volume percent or more.
- the hydrocarbon fuel mixtures to which the invention is applied are substantially lead-free, but may contain minor amounts of blending agents such as methanol, ethanol, ethyl tertiary butyl ether, methyl tertiary butyl ether, tert-amyl methyl ether and the like, at from about 0.1% by volume to about 15% by volume of the base fuel, although larger amounts may be utilized.
- blending agents such as methanol, ethanol, ethyl tertiary butyl ether, methyl tertiary butyl ether, tert-amyl methyl ether and the like, at from about 0.1% by volume to about 15% by volume of the base fuel, although larger amounts may be utilized.
- the fuels can also contain conventional additives including antioxidants such as phenolics, e.g., 2,6-di-tertbutylphenol or phenylenediamines, e.g., N,N′-di-sec-butyl-p-phenylenediamine, dyes, metal deactivators, dehazers such as polyester-type ethoxylated alkylphenol-formaldehyde resins.

- dehazers such as polyester-
- Corrosion inhibitors such as a polyhydric alcohol ester of a succinic acid derivative having on at least one of its alpha-carbon atoms an unsubstituted or substituted aliphatic hydrocarbon group having from 20 to 50 carbon atoms, for example, pentaerythritol diester of polyisobutylene-substituted succinic acid, the polyisobutylene group having an average molecular weight of about 950, in an amount from about 1 ppm (parts per million) by weight to about 1000 ppm by weight, may also be present.
- a polyhydric alcohol ester of a succinic acid derivative having on at least one of its alpha-carbon atoms an unsubstituted or substituted aliphatic hydrocarbon group having from 20 to 50 carbon atoms, for example, pentaerythritol diester of polyisobutylene-substituted succinic acid, the polyisobutylene group having an average molecular weight
- the fuel compositions of the present invention may also contain one or more detergents.
- the fuel composition will comprise a mixture of a major amount of hydrocarbons in the gasoline boiling range as described hereinbefore, a minor amount of one or more compounds of component (b) as described hereinbefore and a minor amount of one or more detergents.
- a carrier as described hereinbefore may also be included.
- the term “minor amount” means less than about 10% by weight of the total fuel composition, preferably less than about 1% by weight of the total fuel composition and more preferably less than about 0.1% by weight of the total fuel composition.
- the one or more detergents are added directly to the hydrocarbons, blended with one or more carriers, blended with one or more compounds of component (b), or blended with one or more compounds of component (b) and one or more carriers before being added to the hydrocarbon.
- the compounds of component (b) can be added at the refinery, at a terminal, at a depot, at a retail site, or by the consumer.
- the treat rate of the fuel additive detergent packages that contains one or more detergents in the final fuel composition is generally in the range of from about 0.007 weight percent to about 0.76 weight percent based on the final fuel composition.
- the fuel additive detergent package may contain one or more detergents, dehazer, corrosion inhibitor and solvent.
- a carrier fluidizer may sometimes be added to help in preventing intake valve sticking at low temperature.
- the Research Octane Number (RON) (ASTM D2699) and Motor Octane Number (MON) (ASTM D2700) will be the techniques used in determining the R+M/2 octane of the fuel.
- the RON and MON of a spark-ignition engine fuel is determined using a standard test engine and operating conditions to compare its knock characteristic with those of primary reference fuel blends of known octane number. Compression ratio and fuel-air ratio are adjusted to produce standard knock intensity for the sample fuel, as measured by a specific electronic detonation meter instrument system.
- a standard knock intensity guide table relates engine compression ratio to octane number level for this specific method.
- the specific procedure for the RON can be found in ASTM D-2699 and the MON can be found in ASTM D-2700.
- Table I contains the engine conditions necessary in determine the RON and MON of a fuel.
- the fuels were injected into the bomb and allowed to vaporize fully, than a stoichiometric amount of air was added.
- the gases were mixed with stirring fans inside the vessel and the contents were heated to the desired temperature. The fans were turned off prior to ignition. Mixtures were ignited using a spark plug. Pressure transducers were flush mounted inside the bob and recorded the pressure rise as a function of time.
- the base fuel physical properties used in the tests can be found in Table II.
- Cyclopropylacetylene in the Base Fuel-1 shows the pressure increase in the combustion chamber 0.1 seconds after ignition of the homogeneous charge is statistically (>95%) significantly greater than the Base Fuel-1 (reference fuel).
- Base Fuel-1 reference fuel
- Cyclopropylacetylene, 1-Pentyne were blended at 0.5% and 1.0% into Base Fuel-2. Each fuel blend was tested in a single day along with the reference fuel (base fuel without the additive) in an A-B-A-B . . . type test design on the chassis dynamometer. A Hyundai Coupe was used for the testing. As this vehicle has shown to be insensitive to changes in fuel octane the improvements in acceleration performance achieved between the test and reference fuel are attributed to changes in the laminar flame speed of the fuel. A standard chassis dynamometer power and acceleration test procedure on a Hyundai Coupe was used to obtain these results as shown in FIG. 3 . The figure shows over 0.2% acceleration performance improvements with 1% cyclopropylacetylene as an additive as compared to the base fuel without the additive.
