DESCRIPTION OF RELATED ART

The use of fuel additives in an internal combustion engine to improve combustion is well known in the art. For example, it is known in that art that a fuel additive containing various metals may reduce soot buildup in an internal combustion engine and thereby improve combustion. Kukin, U.S. Patent No. 3,348,932, for example, discloses a fuel additive containing combinations of various metals designed to effectively reduce soot buildup.

Other fuel additives for improving combustion efficiency of an internal combustion engine and thereby substantially reducing undesirable motor vehicle exhaust emissions as well as fuel consumption levels is offered by Sanders in U.S. Patent No. 5,266,082. The compositions of the '082 Patent are composed of a bicyclic aromatic components selected from the Group consisting of naphthalene, substituted naphthalene, biphenyl, biphenyl derivatives and mixtures thereof, zinc oxide and at least one Group 8-10 metal oxides selected from the Group consisting of iron oxide, copper oxide, cobalt oxide, ruthenium oxide, osmium oxide and palladium oxide, all dispersed in a carrier liquid. In the preferred embodiments, the composition contains a mixture of magnesium oxide, zinc oxide and iron oxide all dispersed in a carrier liquid. Exhaust emissions from internal combustion engines present serious environmental concerns Motor vehicle exhaust emission, in particular, present a serious unchecked problem in many large cities These emissions not only contribute to the smog and pollution problems resulting in the silent continual destruction of the ozone layer and may also cause long term health effects due to their potential toxicity In an attempt to regulate the levels of potentially harmful pollutants in the environment, the Environmental Protection Agency propagated emission standards setting forth acceptable levels of carbon monoxide, nitrogen oxides, paniculate matter and hydrocarbons in the exhaust emissions of various classes of motor vehicles The hydrocarbon content of vehicle emissions is indicative of the fuel burning efficiency in the engine The higher the percentage of hydrocarbons (HC) emissions, the lower the level of hydrocarbons burned efficiently The carbon dioxide (CO_:) content of the emissions reflects the combustion efficiency and catalytic action of fuel components in the engine The higher the carbon dioxide contents, the more efficient the combustive process The carbon monoxide (CO) content of the emissions is also indicative of the level of combustion in the engine chamber A higher level percentage of carbon monoxide in motor vehicle emissions, often caused by lean air to fuel ratio, is indicative of incomplete combustion in the engine chamber The high molecular oxygen (0₂) content in the emissions can mean a lean fuel to air ratio or fouled plugs Ideally motor exhaust emissions contain low percentages of hydrocarbons, carbon monoxide and molecular oxygen as well as a high percentage of carbon dioxide

During the last twenty to thirty years vast sums have been spent in an attempt to improve the gas mileage in modern automobile, truck, tractor and marine engine design and fuel research in an attempt to improve fuel utilization Attempts have been made to operate the engines with lean fuel air mixtures and lead free gasolines as well as modified diesel and two cycle engine fuels But the efforts have been slow in producing satisfactory results especially due to the Environmental Protection Agency rules which are tightened on the specific amounts and types of emissions permitted from these vehicles Achieving satisfactory performance by fuel air mixture is not a complete answer in itself only one of many adjustments which will be required to meet requirements of today and the future as to fuel efficiency utilization and emissions

Fuel additives have been a major focus in these attempts to increase fuel utilization efficiencies Clearly, a need exists to create significant reductions of emissions from a variety of fuels There fuels mav comprise for example, any of many grades of hydrocarbons, petroleum products or diesel The introduction of a fuel additive may occur, for example, in a fuel storage tank or in the fuel line or both The fuel additive itself may be in the form of a dry powder, a semi-dry paste or a suspension of paniculate matter in carrier liquids, or even a combination of suspension, emulsions and partial solutions In use, it is believed that a chemical reaction takes place between the fuel additives and the fuel, and that the products of the chemical reaction are traced into the fuel in minute molecular form, thereby not only improving the combustion of the fuel but also reducing the friction of moving parts in contact with the fuel Tvpical fuel modifiers and fuel additives include various organic components such as naphthalene camphor, tauπne and benzoyl alcohol as well as different gasoline fractions To condition the additive vaπous alcohols and other oxygenated fuel extenders are used in such a way to serve as a fuel substitute resulting in a decreased amount of actual fuel usage especially in the absence of tetraethyl lead and similar other banned additives Stπngent diesel emission regulations are also being implemented worldwide and in the

United States, the 1990 Clean Air Act mandates lowering oxides of nitrogen (NO emissions to 4 0 grams per horsepower-hour for the 1998 model year The future proposals by the U S Environmental Protection Agency call for further reduction of combined (NO ) and hydrocarbon emissions from heavy trucks and busses to 2 5 g/hp-hr for the 2004 model year Such reductions will require a combination of new engine technology and economically viable new diesel fuels having lower emissions

Creating premium gasoline and diesel fuels with performance additives which meet combustion efficiency goals as well as the E P A mandates is a continuing challenge which has not been completely met by the current available market products Today the use of additives in industrial and other transportation areas is relatively low, and the automotive gasoline and diesel fuel segments will continue to present a strong growth opportunity for additives However, the additives, for example combustion catalysts must satisfy economic, governmental regulations and the reliability demanded by the public, the producer and the

E P A Demand for gasoline and other fuel additives is projected to expand to over ten billion dollars in the year 2000 Also by the year 2000, gains in commodity additives such as oxygenates will nonetheless decelerate since much of the legislative driven growth will already have been garnered While major additive manufacturers provide a variety of high quality additives developed primarily as lubricants, very few of these additives directly address the combustibility charactenstics of fuels Hence they have had little or no direct impact on fuel consumption, NO_x or paniculate matter Instead they increase the amount of smoke and/or other emissions such as hydrocarbons and carbon monoxide-carbon dioxide There is a continuing need by world energy users, particularly with respect to the internal combustion engine, to find fuel additives, fuel blends, and corresponding engine designs and the like which when combined with properly modified fuels and burned in the internal combustion engine cylinder will provide fuel efficiency as well as a friendly environmental emission systems In addition these various elements required for the future internal combustion engine performance must be competitive in pricing for the general public to utilize the engine, and the fuel source As petroleum based-oil fuels diminish due to unavailability and decreased world wide production, combustion efficiency, engine design and the like must be fine tuned and brought to bear in order to fill economic expectations as well as environmental emission standards Only in this way can the petroleum industry provide the consuming public with continuing fuel availability SUMMARY OF THE INVENTION

The present invention is directed to fuel additive compositions, the modified fuels resulting from the use of fuel additives, and to processes for improving combustion and substantially reducing hydrocarbon, carbon monoxide and molecular oxygen motor exhaust emissions Combustion catalysts for internal combustion engine fuels which enhance combustion efficiency by substantial reduction of hydrocarbon and carbon monoxide emissions is achieved by utilization of selected oxides of Group IIA and Group IIB elements provided in effective amounts generally in the form of a suspension when combined with a liquid carrier In accordance with the present invention the catalyzed or modified fuels contain from about 10 to 200 or 300 or greater ppm of the Group IIA or Group IIB element oxides These catalyst when blended with a carrier and added to a fuel have been found to provide the internal combustion engine with improvement of combustion efficiency and demonstrate that the emissions of such modified fuels meet or exceed E P A standards The fuel additive composition comprises an effective amount of Group IIA and Group IIB metal oxides selected from the Group consisting of zinc oxide, zinc peroxide, zinc hydroxide, strontium oxide, strontium peroxide, calcium oxide, calcium hydroxide and calcium peroxide These metal oxide or metal hydroxides combustion catalysts have reduced particulate size in order to form suspensions with earner liquids for direct additive to the end user fuel tank or as an addition to larger storage tanks of the distributor and manufacturer In other aspects these selected Group IIA and Group IIB metal oxides can be inserted or aspirated into the combustion chamber through other means as a dry paniculate matter but for most common usage will be applied as a liquid carrier suspension The liquid carrier suspension of the combustion catalyst is comprised of at least 90% by weight of a carrier liquid selected from a group of hydrocarbons in the kerosene boiling range as well as other components which can be utilized individually or in combination for example, the C,-C., monohydrate, dihydrate, or polyhydrate alcohols and mixtures thereof In addition, various aromatic components such as naphthalene, substituted naphthalene, biphenyl biphenyl derivatives and mixtures thereof can be utilized as carriers, as well as hosts ot hydrocarbon solvents The choice of liquid compounds suitable for forming suspsensions of the finely divided metal oxides include not only the common solvents, but also other compounds whose properties render them suitable as solvents or liquid suspension carriers Hydrocarbon solvents can be arranged in order of increasing chemical complexity under the following major classes compounds with one type of characteristic atom or Group (hydroxide compounds, esters halogenated and the like), and compounds with more than one type of characteristic, atom or Group (ether alcohols, amino alcohols, esters of keto acids and the like) In addition other liquid carriers which possibly do not meet the definition of solvents can be utilized to form suspensions comprised of these liquid media having small solid particles of the metal oxides more or less uniformly dispersed therethrough If the particles are small enough to pass through ordinary filters, and do not settle out on standing, the suspensions can be called colloidal suspension, however, various physical forms of the suspension including solvents may have other physical chemistry factors which bear on the stability of the suspension as well Dispersions and colloidal solutions of metal oxides have in recent times found numerous applications in industry, for example, as fuel oil additives, paints and inks

In another aspect the fuel additives provide a method for increasing the cetane number of diesel fuels which results in cleaner burning diesel fuels The combination catalyst additives improve cetane and provide economical improvement in cetane which is less expensive than hydro treatment of diesel fuel which lowers the aromatic content of diesel The combustion catalysts additives according to the invention are chemical cetane improvers and are compounds which are elevated temperatures readily decomposed, and in turn promote the rate of chain initiation, 1 e emission improvement for diesel fuel

DET AILED DESCRIPTION OF THE INVENTION

The present invention is directed to fuel additive compositions and processes for improving combustion in internal combustion engines as well as the modified fuels, the result being substantial reductions of potentially hazardous exhaust emissions This invention is particularly adapted for reducing the percentages of hydrocarbons, carbon monoxide and molecular oxygen in motor vehicle exhaust emission Use of the combustion fuel catalyst additive compositions may also result in increased mileage performance as well as an increase in percentage of carbon dioxide in the motor vehicle exhaust emissions However, with calcium peroxide even the gaseous carbon dioxide emissions are reduced

FIELD EVALUATION OF THE ADDITIVES EMP™ AND EZP IN MOTOR GRADE GASOLINE

EXPERIMENTAL TEST PROCEDURE

The test protocol involved sampling the tailpipe emissions of the test cars for four different gases HC (hydrocarbons), CO (carbon monoxide), C0₂ (carbon dioxide) and 0₂

(oxygen) It was not possible to measure N0 levels in the exhaust with the test sampler used in this study Of the gases that were sampled, those impacting the environment were of the most concern (HC, CO and C0₂) The levels of these three gases in the exhaust were monitored while the engine was running at idle and then at 2000 rpm The cars were first tested randomly on gasoline as it was received from the retail pump The data from these tests are given in Table 2 The vehicle used was not recorded so as not to bias subsequent tests The cars were then refueled, but this time using gasolines and the EMP™ additive

The combustion catalyst EMP™ is EnviroMax Plus which is formulated by blending together by weight 40% naphthalene crystals and 60% powdered zinc oxide (particle dιameter< 1 micron) Just enough methanol was added to make a smooth paste Then 250 grams of this naphthalene-zinc oxide paste was added to 32' allons of solvent mixture It has also been found that the oxides, peroxides and hydroxides of the Group IIA and Group IIB metals of the Periodic Table are good catalysts for use with hydrocarbon fuels to reduce gaseous, tailpipe emissions However, because some of these metals and their oxides are only a limited number of the Group II elements can actually be used

In order to prove the catalatic effects of the inventive additives a sample of zinc hydroxide was obtained, along with samples of magnesium peroxide, calcium peroxide, strontium peroxide, and barium peroxide Tests with zinc peroxide have shown that the peroxides are the preferred form of these potential combustion catalysts, because the metal peroxides can supply additional oxygen for the combustion process within the cylinder of the engine The more stable, single oxide form of these metals can also act as an oxygen supply, but the available oxygen in the case of the oxide is only one half that of the peroxide

Similarly, the hydroxides of these metals can supply the same amount of oxygen as the metal oxide However, the hydroxides are attractive because of their lower specific gravity versus that of the oxides Typically, the smaller the specific gravity of the additive, the greater will be the amount and stability of the suspensions in the liquid fuel Of the Group IIA and Group IIB elements that were tested the peroxides of zinc, calcium, and strontium were found to be the most effectiv e Zinc oxide and zinc hydroxide also performed well However, the other Group IIA and Group TIB elements were either too toxic to be used or too ineffective to be considered as good fuel catalvsts The rejected elements included beryllium (toxic) magnesium (ineffective) cadmium (toxic) barium (ineffective), mercury (toxic) and radium (toxic)

For emission testing, the oxygen rich Group II elements were suspended in several solvents and the suspension was then added directly to the liquid hydrocarbon fuel The solvents were blends of ethanol, methanol and VM&P (varnish makers and painters solvent) Concentrations of the metals suspended in the solvents ranged from about five (5) to about 500 ppm or greater by weight However, the tests also indicated that the metal oxides could be added directly to the liquid fuel without solvents and still be active catalvsts Finally, the tests also indicated that combinations of the metal oxides could be used Thus calcium peroxide, which was found to be su risingly effective for the reduction of carbon dioxide, also worked when blended with the zinc oxides

The solvent mixture contains 5% methanol, 10% ethanol and 85%VMP by volume This suspension or solution of solvents is filtered to remove filterable particulate and the filtrate is bottled as the EMP™ product In addition other catalyst such as zinc peroxide has been found to very effective in use with fuel blends, gasoline, diesel and the like in increasing performance and promoting a cleaner burn This catalyst product (EZP) is made the same way that EMP™ is made, except that 2 to 4 grams of zinc peroxide is added to 1 kilogram (32 fluid oz ) of the EMP™ paste, and then added to the solvent mixture These catalysts are present in the inventive fuel blends in amounts of from about 5 to 10 ppm to about 300 ppm or greater, limited only by separation from suspension The performance of these catalyst spiked fuels were compared with the performance of a typical consumer gasoline as the baseline Emission tests were then rerun after a short period of time (10 minutes) to allow equalization and a reasonable expectation that the fuel with the additive had reached the engine Once again the two different engine speeds (idle and 2,000 rpm) were monitored

The data for gasoline containing the EMP™ additive are given in Table 3 Finally, the EZP additive was added to the fuel and the same test procedure repeated However, because EZP represented a new additive formulation, more test replications were run with this fuel mixture The data for the gasoline containing the EZP product is given in Table 4 Also shown in all the tables is a column labeled "% Total Carbon as CO" The values listed under this column represent an estimation of the potential for increased fuel economy For example, when carbon in the exhaust appears as C0₂, it represents a complete chemical combustion (oxidation) of that part of the carbon originally present in the fuel The carbon monoxide fraction (CO), however, represents carbon that still has fuel potential for additional combustion For that matter so does the HC fraction of the exhaust However, the HC fraction is listed at concentrations of ppm where as the CO is listed as percent This means that the CO concentration is at least an order of magnitude greater than that of the HC, and hence the CO represents a greater reservoir of untapped chemical energy which went unburned during its passage through the engine If the CO in the exhaust would have been completely oxidized to C0₂, then a greater fuel economy, i e more miles per gallon, would have been realized Therefore, it was postulated that the percentage of carbon represented as carbon monoxide in the exhaust gases, relative to the total carbon in the exhaust, represented a potential percentage increase in mileage Thus when the observed CO levels were high, the engine was assumed to be operating with less efficiency, and some fraction of the potential fuel economy was being lost If the exhaust concentration levels of CO were observed to be low, then the fuel economy was assumed to be near maximum, and the percent levels listed in this column of the tables should approach zero This approach to the estimation of lost potential fuel economy is considered to be conservative, however It is conservative because of the presence of a catalytic converter on all newer cars The intent of having or requiring a catalytic converter is to assist in a more complete oxidation of all products of incomplete combustion in the engine's exhaust However, since the catalytic converter is installed on the exhaust system after the engine, any combustion that takes place in the converter can not be used in the power producing cycle of the engine Since all the cars but one in this test had catalytic converters, the exhaust concentrations were actually the combination of combustion reactions in both the engine and in the catalytic converter Therefore, overall, the catalytic converter primarily reduces the HC levels in the engine exhaust and has little if any effect on CO concentration levels Hence, by considering as we did that only the carbon in the CO in the exhaust gases represents a measure of lost fuel value, then the predictions of potential fuel economy that are listed in the tables should be conservative

HC Emissions The data in Table 2 suggests that on average slightly more HC is emitted at high rpm than at idle engine speeds However, because of the wide scatter in the data sample, these levels of HC emissions are probably identical The data in Table 3 suggests that with the addition of EMP™ to the gasoline, no improvement over that observed for the regular fuel for the average HC emissions at idle However, the addition of EMP™ to the gasoline did on average produce a 30-35% decrease in HC emissions at the higher 2,000 rpm. Table 3 shows a drop in the averaged HC concentrations of from 124 6 ppm at idle down to 84 9 ppm at 2,000 rpm This is significant even in light of the scatter in the data sample The data in Table 4 suggests that the use of EZP in the fuel was even more successful at reducing HC emissions With the EZP additive the reduction relative to the regular gasoline occurred both when the car was idling or at the 2,000 rpm level In both cases the average HC levels consistently dropped into the 30 to 40 ppm range These low levels, represent on average, a 70% drop in CO emissions when EZP is added to the fuel This is indeed significant by any measure Because of variations between individual vehicles only average levels of hydrocarbons in the exhaust emissions for each of the different tests was used to prepare 'the graph in Figure 1 This bar graph highlights the significant reduction in FIC levels

CO Emissions The third column of data in Table 2 indicates that for averaged CO emissions there is a significant difference between idle speeds and 2,000 rpm when the regular gasoline was used When the automobile is at idle, CO emissions averaged 0 44% When the engine was turning at 2,000 rpm the CO emissions jumped to more than four times that level, or 1.84% By contrast, the next table, Table 3, shows that the addition of EMP™ to the fuel resulted in a reversal of the averaged CO emissions between idle and 2,000 rpm In this case, CO emissions dropped from 1 51% at idle down to 0 95% at 2,000 rpm Overall, these averaged values indicate that the addition of EMP™ during this test did not significantly reduce the CO concentration levels below those which were observed in the emissions produced with the regular unleaded gasoline However, Table 4 indicates that the addition of EZP to the gasohne did result in the reduction of the CO concentration level in the exhaust gases to 044% at idle and 0 65% at 2,000 rpm On average this reduction represents a 50% decrease in CO emissions over those observed for the regular gasoline fuels These differences in CO emissions for all the tests are depicted by the bar graph in Figure 2 CO, Emissions

Whenever the HC and CO emission levels are reduced in any combustion process, then the carbon dioxide emission should increase that is unless the additional CO, which is being produced is also in some way being removed The potential chemical reactions that are possible with the ingredients in EMP™ and EZP suggest that this could be the case I e that the carbon is removed as a carbonate rather than being emitted as carbon dioxide The data in Tables 2, 3 and 4 suggest that indeed the addition of EMP™ and EZP do increase the averaged percent emissions of CO, over those measured for the regular gasoline alone An average, base level of 10 2% carbon dioxide was recorded for the tests with just regular gasoline The averaged CO, level was observed to increase to 12 7% when EMP™ was added to the gasoline, and then rose to an additional averaged value of 13 5% when the EZP was added It should be noted that the maximum CO, concentration (on a dry basis) for combustion of a saturated, paraffin hydrocarbon using stoichiometπc air is approximately 14 5% This theoretical level rises to 15% for naphthionic hydrocarbons and to 17% for aromatic hydrocarbon fuels In the expeπmental tests excess air is typically used Under such lean burning conditions, the theoretically predicted percentages of CO, in the exhaust (14 5%,

15% and 17%) should be reduced in the direction of the 13 5% level which was measured Hence, we have concluded that while the use of EMP™ and EZP as additives to gasoline do not reduce the emissions of the "greenhouse" carbon dioxide from internal combustion engines, both additives can reduce the levels of HC and CO in automobile emissions by increasing the level of combustion of the fuel The bar graph in Figure 3 substantiates this by depicting the increases in carbon dioxide emissions when the additives were utilized Reductions of the magnitudes observed in this studv for HC and CO would be significant to improvements being sought to air pollution problems in which HC, CO and NO together with UV, can trigger serious health problems in highly congested population areas

% Total Carbon as CO As mentioned earlier, any increase in vehicle fuel economy should be directly aligned with an overall decrease in vehicle emissions per mile of travel Thus the last column in

Tables 2, 3 and 4 was generated in an attempt by the investigators to tie any decrease in the CO emissions to a potential percentage increase in fuel economy This hypothesis is based on the assumption that EMP™ and EZP are both active in the combustion process in the engine, and both are not just assisting the reactions taking place in the catalytic converter This assumption is also based in part on hearsay reports from users of both products that the mileage on their cars increased when the additives were being used The increases in mileage were reported by customers to range from 3% up to 30% The data in Tables 2, 3 and 4 suggest that on average a 4% increase in mileage is very probable when EMP™ is utilized and an averaged 6% increase in mileage would be realized with the use of EZP The higher potential increases in fuel economy would be possible only when an automobile is not kept well tuned and combustion within the engine is incomplete Of the seven vehicles in this study, at least one was found to be in need of a tune-up Hence, with a proper tune and the use of EMP™ or EZP, the operator of that car might realize a step improvement in their fuel economy of greater than 10% This limited field test has demonstrated the very significant potential derived from the use of the additives EMP™ and EZP in gasoline to reduce undesirable emissions of hydrocarbons (HC) and carbon monoxide (CO) Even though the data were scattered, this conclusion was reached based on comparisons between the averaged values of emissions from seven different cars fueled from five different retail gasoline sources The study also concludes that these undesirable pollutants can be reduced with a simultaneous increase in fuel economy This means that the emissions of HC and CO per mile of travel will be even more enhanced and harmful pollution further reduced

SUSPENDED FUEL CATALYSTS

Data were collected as a result of field studies on twelve different used cars These cars had never been exposed to catalyst products, and the study represents a one time testing only In every case, the cars were fueled with regular gasoline The tailpipe emissions were then recorded with a Sun, four gas analyzer, (HC, CO, CO, and 0₂) These data were taken while the cars were stationary first with the engine running at idle and then with it running at 2000 rpm The test samples of the peroxides, oxides, or hydroxides of the selected Group II elements (suspended in ethanol) were then added to the fuel in the gas tank of the car The cars were then dπven for 16 miles and a retest of the tailpipe emissions was performed The Figures 5-1 1 show the emission levels before and after the addition of the suspended catalysts

EXPECTED RESULTS

Earlier work with zinc oxide and zinc peroxide indicated that these two additives, when suspended in fuels, crated conditions which produce a more complete combustion of the fuel in internal combustion engines It was suspected that other Group II elements in the

Peπodic Table might also exhibit such behavior If the oxides of these other elements were successful, then the like with the zinc catalyst, the hydrocarbon and carbon monoxide levels in the exhaust emissions should go down while the carbon dioxide levels in the exhaust increased This outcome is assumed to be indicative of a more complete combustion of the fuel Figures 5 through 1 1 show the results of the successful test which were observed If there were no changes in the gaseous emission levels, these data were recorded but not plotted However, the negative results are noted in the preceding summary However, with calcium peroxide, the carbon dioxide levels in the exhaust emission sometimes went down instead of up This was attributed to the reaction between calcium oxide with carbon dioxide, produced dunng combustion, to form calcium carbonate Hence, a blend of calcium peroxide with zinc peroxide might be used to substantially eliminate most of the harmful and greenhouse gaseous emissions from automobiles Figure 5 Tests performed with zinc hydroxide (ZH) suspended in ethanol and added to the regular gasoline in the tank Car (1) was an Olds Cierra with 99,389 miles Car (2) was a 1994 Chevy Pickup with 104,250 miles Except for car (1) at high rpm, the zinc hydroxide produced a substantial decrease in the carbon monoxide levels in the exhaust emission The anomaly observed with car (1 ) at high rpm should disappear after the car is driven greater distances on the ZH fuel catalyst additive

Because the practice of refining crude oil to produce and improve the quality of motor gasoline has been extensively developed over the last several decades, a number of standard tests to measure quality have evolved. These tests have become routine to the extent that they have received ASTM designations and/or, in the case of corrosion, the test have been sanctioned by NACE (National Association of Corrosion Engineers). Since the additives EMP™ and EZP are added to motor fuels as a means decreasing emissions and increasing engine performance, it seemed appropriate to subject blends of gasoline and diesel with EMP™ and EZP to several of the more common laboratory tests. Core Laboratories of Houston, Texas was selected as an independent laboratory and requested to perform the ten tests listed in Table 6.

The attached data sheets and graphs give core laboratory's finding from these ten tests Their results are summaπzed here It should be kept in mind that the active ingredients in both EMP™ and EZP are solid particulate matter which has been suspended in selected solvents prior to addition to the liquid fuel By design the concentration of suspended solids should not exceed 10 ppm In fact the "particulate matter" test (ASTM - D-2276) indicates that there was only 1 to 2 mg per liter (ppm) in the gasoline sample which were tested Regular, pump grade gasoline by comparison was shown to have concentration of particulate matter of less than 0 1 mg per liter

Because the additives represent such a small fraction of the fuel blend, the property of "fuel ash content" by ASTM - D-482, and the "fire and flash point" characteristics by ASTM - D-92 of the pump grade gasoline were found to be unaffected by either additive However, both of the additives appear to decrease the "heat of combustion" level for the fuel by 1% The change in this property, which is indicative of the energy content of the gasoline, may not be significant overall if the particulate catalysts actually provide more complete combustion in the engine Other tests on the gaseous emissions from engines with fuels containing EMP™ and EZP appear to confirm that more complete combustion of the fuel does in fact occur when the additives are present.

With respect to the Ried Vapor Pressure (ASTM - D-5191), the EZP product caused and increase of just over 7% in RVP, while the EMP™ produced no change at all Generally, the lower the RVP the less volatile the fuel, and the lower the amount of fugitive emissions of hydrocarbons form the fuel The EZP also produced much higher levels of peroxide in the tested gasoline blends in which EZP was used This was not unexpected; since EZP technology is based on the use of a peroxide as a catalyst The only major concern with peroxides in the fuel is that any cracked fractions of the gasoline (unsaturated aliphatic hydrocarbons) may polymerize and form resin deposits However, these same peroxides in an aromatic based fuel can help open the aromatic ring structures and prevent carbon deposit formation in the engine Hence, EMP™ and EZP might be tailored for different types of fuels, if the fuel analysis is known The EMP™ product also appeared to be more effective at increasing "research octane" and "research cetane" levels of the fuels in which were tested It is still not understood as to how or why this increase takes place Moreover, the increase generated by the use of EMP™ did not occur with the higher, premium octane grades of gasoline This might imply that the solvents used with EMP™ and EZP produce the observed octane and cetane increases

Finally, the addition of EMP™ and EZP to regular U S , pump grade gasoline does not appear to change the ASTM - D-86 distillation test However, the Pemex regular grade gasoline had a flattened area over the range of 20% and 50% distillation This flatten area was removed by the addition of EMP™ and EZP to a more favorable linear increase This change implies that the Pemex gasoline should perform better in the engine when EMP™ or

EZP is added

The above data while being inconclusive should further be compared with cetane

ASTM D-613 analysis of commercially available diesel which gave a cetane number of 47.6. The same diesel fuel utilizing ZP (zinc peroxide) and TP8 (tertary butyl hydroperoxide) raised the cetane number to 63.7. In addition, a second commercially available diesel sample treated with zinc peroxide and tertary butyl hydroperoxide provided a cetane number of 73.1 These tests clearly indicate that the combinations in zinc peroxide and an organic peroxide as an additive to diesel yield substantial increases in cetane which is most desirable. In addition, Pemex diesel without additive provided a cetane number of 51.0 and yet when provided with an additive of zinc peroxide and tertary butyl hydroperoxide yielded a cetane number of 73.1. Clearly the combination of a metal oxide additive with an organic peroxide utilized in combination with commercially available diesel supply increases cetane numbers substantially as much as 53%

STUDIES OF FILTERS

A Ford Econoline E350 Diesel Van was used to test the effectiveness of fuel additive ZP for reduction of particulate emissions This vehicle had appr oximately 63,000 miles on its odometer and a thirty gallon fuel tank The van's gas tank was filled with commercial , pump-grade diesel fuel from a local Lubbock, Texas retail outlet The Van was driven in normal street traffic to warm up the engine Following this warm up period, the particulate exhaust emissions from the tailpipe were captured with a high volumetric filter at an isokinetic air velocity The particulate matter was first captured at an idle engine speed and then again at a high engine rpm However, the Van was stationary at all times during these tests. Once these background data had been collected, the ZP fuel additive was added to the

Van's fuel tank The additive consisted of 8 ounces of an ethanol carrier containing the zinc peroxide (ZP) catalyst at a concentration of 200 ppm The Van was again driven in city traffic for fifteen minutes to make sure that the additive and the fuel were reasonably well blended After this stabilization period the particulate matter in the exhaust was again sampled at the isokinetic air velocities associated with idle (30 mph) and high (60 mph) rpm engine speeds

The filters used in these tests were 8" x 1 1 " sheets of Whatman No 1882-866 These filters consist of random mats of pure borosilicate glass fibers which enable detailed chemical analysis of trace pollutants with minimal interference and background The filters have been heat treated to remove any residual organic traces and are rated at a 99 99% efficiency for

DOP 0 3 micron sized particles The filters were especially developed for high volume air sampling of atmospheric particles and aerosols and are approved by EPA Microscopy The test filters with the exhaust debris attached were sent to SemTech, Inc. For microscopy analysis Each filter had a 3/8-inch diameter sample cut from a random location on the filter These samples were then mounted with carbon tape on individual stubs with the appropriate side up and examined at 400X to 600X Particle sizing , energy dispersive X-ray analysis spectra (EDX), and scanning electron microscopy (SEM) were performed on each sample The specific instrument used for these measurements was an Hitachi S-2460N Scanning Electron Microscope interfaced with a calibrated NORAN Voyager III X-ray/image analysis system The data from the microscopy studies were reduced to indicate the number of particles per square mm of the filter surface captured during a thirty minute test Several individual particles were also analyzed for chemical composition The average length to width ratio of the particles was also determined, and these are also shown in Table 8 This table indicates that the use of the additive generated a 60% reduction in the numbers of particles in the exhaust for an idle engine rpm and a 30% reduction at high rpm The LAV ratio indicated that the particles produced prior to the additive had higher aspect ratios indicative of rod or stick like shapes, while the particles produced after the additive was used were more spherical or elliptical in shape As expected, the high engine rpm levels with the higher isokinetic velocities always produced more particles on the filter surfaces which were skewed towards larger average particle sizes

In both cases, with and without the additive, the particles were found to consist primarily of oxides and other minerals of iron, sulfur, phosphorous, and copper These elements are common to the additives used in diesel fuels, or to the metallurgy of the engine For example, sulfur and phosphorous can be found in the fuel, while iron and copper are common wear metals from engine components Another study has shown that the use of the ZP additive can reduce the amount of wear metals formed during engine operation while the levels of sulphur and phosphorous remain dependent on the fuel being used

Finally, as noted above, the lower engine rpms produced particles with smaller size distributions, while the exhaust velocities at the higher rpms were capable of sweeping more and larger sized particles out of the exhaust system This is a kinetic energy effect in which more and larger particles are entrained and translated at the higher velocity Also shown in Table 8 for comparison purposes are the same types of data taken from a vehicle fueled on regular unleaded gasoline. In this case the numbers of particles are greatly reduced for gasoline versus diesel, and the additive was found to actually add to the particulate emissions at low rpm engine speeds

ANALYSIS OF FILTER SAMPLES

Nine other samples were glass fiber filters identified as #l -#8 and E520 Elemental analysis and the size distribution were to be performed on a random selection of particulates on the filters

METHOD OF INVESTIGATION

Scanning Electron Microscopy (SEM) and Energy Dispersive X-ray analysis (EDX) were performed using a Hitachi S-2460N Scanning Electron Microscope interfaced with a Noran Voyager ITT X-ray/image analysis system The microscope and the NORAN voyager III system were calibrated prior to particle size measurement. The results of the particle size measurements were tabulated and plotted using an Excel spreadsheet

DETAILS OF INVESTIGATION The samples 1-8 and E520 were examined for the constituent elements of particulates on the glass fiber filters. Each of the nine filter samples had one 3/8-inch diameter pieces taken randomly from the filter. Samples were mounted with carbon tape on individual stubs with the appropriate side up. Each specimen was examined at 400X - 600X The area of the field was calculated according to the magnification used Particle sizing and EDX spectra were made of 10 to 20 fields in each of the nine samples Table 10 shows the elements present in particulates found on the respective 9 filters The last entry are the background elemental constituents of an unused, clean area on a glass fiber filter

The shaded area in Table 10 are elements found in the glass fiber filter In order to distinguish these background elements from the particulates found on the filter, each spectra collected had the background elements' peaks subtracted form each EDX spectrum to the degree consistent with the amount found in background control spectrum The remaining peaks, even elements previously identified as background elements, are a true depiction of the constituent elements of a particulate

Particulate size distribution was determined using the Noran Voyager image analysis software Images were converted to a binary format and then adjusted so that only the particulate binary images remained The software then determined the area, length, and width dimensions of the particulates This process was followed for images from all filters Table 11 shows the averages for each of the nine Groups

The data of Table 12 indicates that new oil is relatively clean Of the eight (8) metals examined in the test, zinc, copper and iron appear to be the biggest contributors to contaminated oil However as can be seen the iron contamination is reduced substantially through the use of E M P after 3000 miles as is zinc and copper Differences in oils, equipment, locations and operations prohibit a simple guideline for establishing where metal limits will fall. However, significant increases from one sample to the next of five (5) to ten (10) ppm or 100% , whichever is greater, should prompt concern. One should also be reminded that zinc is considered to be an antiwear additive and is typically utilized in the industry as an additive for lubrication purposes. On the other hand, most iron complex particulate material is generally quite hard (used as a polishing powder) and creates wear problems through its presence in the lubricating oil.

Outboard marine two cycle engines were tested utilizing EnviroMax Plus fuel catalyst. The initial deposit results of a small 9.9 horsepower, two stroke outboard engine utilizing EMP™ additive were most encouraging. After four (4) hours of engine service utilizing oil-gasoline blend, treated with EMP™ at the rate of one (1) fluid ounce per five (5) gallons of blend fuel, the combustion chambers of the two cycle engines as well as piston tops of the two cycle engine which was a used engine at the beginning, were cleaner and drier. The exhaust system was clean and dry with the complete disapperance of the normally oily deposits. The combustion catalyst additives in accordance with the present invention were most suitable for enhancing cleaner burn with less emissions even in two cycle engines as indicated by the two cycle used engine evaluation test. Miles Per Gallon Test

On April 4, 1998, test were run on a 1995 cadillac fleetwood brougham having a mileage of 20.750 from Lubbock to Dallas, Texas with mileage going out to Lubbock from Dallas at 20J miles per gallon on a 93 Octane gasoline. Temperatures on the return trip from Lubbock to Dallas, Texas ran from 68 to 75 degrees Fahrenheit averaging. The 150 miles had a 10-20 mile headwind for the full trip. The fuel used was 91 Octane (Premium) for the high planes of Phillips 66 Premium fuel with catalyst comprised of zinc peroxide and tertiary butyl hydroperoxide blend at a rate of one ounce per five gallons (0.18 ounces per gallon of each additive). Speeds were 50-80 miles per hour with an average on the interstate or major portion of the trip at 75 miles per hour. The trip was for 348 miles using approximately 14.8 gallons for a mileage per gallon ratio of 23.5. The 23.5 represented a 13.6% improvement vs. the 20J miles per gallon.

Another test was run on April 12, 1998 for 120 miles of 30 or 40 headwinds in a raised top wheelchair 3/4 GMC Van of 1992 vintage. The van has a 350 engine and automatic transmission. The temperature was 72 degrees F averaging with a mileage of about 40,000 miles. The van used 1 1.94 gallons on 93 octane purchased in Dallas for a 12.8 miles per gallon averaging 55 to 75 miles per hour on state roads and interstate 35 between Oklahoma and Texas

The same van, 1992 GMC 3/4 ton high top van with a 350 engine having 41 ,200 miles was again tested on April 13, 1998 with 93 Octane Phillips and 7 ounces fluid combination of zinc peroxide and tertiary butyl hydroperoxide blended liquid additive (0 18 ounces per gallon of zinc peroxide and 0 18 ounces per gallon of tertiary butyl hydroperoxide) added to the tank an average of 50 to 75 miles an hour and with a ambient temperature of 74 degrees and a tailwind of 10-20 miles per hour along at least a major portion of the trip on 1-35 between Oklahoma and Texas The other portions either had head winds of about 20 miles an hour or crossw ds or at a drive-in restaurant with the air conditioner on at idle speed for 20 minutes Miles traveled were 155 miles utilizing 91 Octane Phillips premium purchased at Ardmore,

Oklahoma yielding a miles per gallon of 14 9 versus a normal for this vehicle of 10 miles per gallon with no additional combination catalyst

Further use of the catalyst and premium fuel Phillips 91 Octane purchased in Dallas, for over 400 miles yielded an average of 35% increase for city and highway driving for this 92 van which had never had the plugs changed in over 40,000 miles

The following tables and test data show fuel improvement using catalyst according to the invention and are self-explanatory EDM is an expression for the tertiary butyl hydroperoxide Other organic oxides and peroxides can be utilized according to the invention but the tertiary butyl hydroperoxide single or in combination with the other additives, has been best for diesel and gas mileage
