Description

DETAILED DESCRIPTION OF THE INVENTION

Example 1. Method for Improving Diesel Fuel Efficiency of the Present Invention and Results for Pour Point, Cetane Index, Calorific Value and Total Sulphur

[0027] 10 liters of diesel fuel were introduced in a fuel tank. A frequency generator was connected to the fuel thank by means of two electrodes. These electrodes were introduced in the fuel tank. A resonance frequency between 1.600 to 1.750 Hz was applied to the diesel fuel during at least one hour. The fuel obtained was compared with two samples of commercial diesel fuel.

[0028] Table 1 shows the values obtained from the pour point, cetane index, calorific value, and total sulphur for two samples of commercial diesel fuel (samples 1 and 2) and a sample of diesel fuel treated by the method of the present invention (treated sample).

TABLE-US-00001 TABLE 1 Values obtained for the pour point, cetane index, calorific value and total sulphur of the samples analyzed. Measurement Treated Test method used Sample 1 Sample 2 sample Pour point ( C.) ASTM D97 1.1 1.1 6 Cetane index ASTM D976 45 45 55.4 Calorific value ASTM D240 20.001 (Btu/lb) Total sulphur ASTM D1266 0.5 0.5 0.019 (wt %)

[0029] In the values obtained (see Table 1), the sample treated with the method of the present invention presents an increase in the Cetane index of 10 points and an increase in the calorific value from 192 00 Btu/lb to 20 001 Btu/lb, which indicates that it delivers more energy during the burning of the fuel thus increasing the fuel efficiency in kilometers per liter.

[0030] The treated sample also presents a reduction in the percentage of sulphur falling from 0.5% to 0.019% by weight, which ensures a better lubricity in the equipment and less wear of parts due to corrosion, such as fuel pump, filters, injectors, rings among others.

[0031] The reduction in sulphur content also means less pollution of the atmosphere by exhaust gases from vehicles and industrial plants; fuels with a high sulphur content release sulphur oxide (SOx), which are precursors to acid rain and other greenhouse gases.

[0032] The improvement in combustion allows to obtain up to 25% increase in power, an increase in performance in kilometers per liter of 20% and a substantial decrease in the emission of polluting gases and avoiding the noise (known as rattle or piston) that occurs when using low-octane gasoline.

[0033] There is also an improvement in the pour point from 1 C. to 6 C., which is very useful for use in mining centers at high altitudes and low ambient temperatures.

Example 2. Method for Improving Commercial Gasoline Efficiency of the Present Invention and Results of Dynamometer, Density, and Viscosity Tests

[0034] 10 liters of commercial gasoline were introduced in a fuel tank. A frequency generator was connected to the fuel thank by means of two electrodes. These electrodes were introduced in the fuel tank. A resonance frequency between 1.600 to 1.750 Hz was applied to the gasoline during one hour. The gasoline obtained was compared with one sample of commercial gasoline.

[0035] Table 2 shows the values obtained in a dynamometer study measuring the power in wheels and torque using one sample of commercial gasoline (sample 1) and a gasoline treated by the method of the present invention (treated sample).

TABLE-US-00002 TABLE 2 Values obtained from the dynamometer test of the samples analyzed. Increase Test No. Sample 1 Treated sample (%) Torque [N-m] 1 101.90 118.90 16.68 2 113.40 118.60 4.59 3 116.80 119.00 1.88 Average 110.70 118.80 7.32 Wheel power (kw) 1 12.00 22.20 85.00 2 14.80 22.60 52.70 3 17.10 22.80 33.33 Average 14.60 22.50 54.11

[0036] The values obtained show an average increase of 7.32% in torque and 54.11% in power at the wheels in the dynamometer tests carried out with the gasoline treated by the method of the present invention.

[0037] The change in density and viscosity of the fuel was also tested. Table 3 shows the density measurement by gravimetry using a pycnometer with a volumetric capacity of 25 ml, both for the treated sample and the sample 1.

TABLE-US-00003 TABLE 3 Density values obtained by gravimetry of both samples. Vacuum Full Pycnometer pycnometer Period (g) Treated 32.54 51.89 19.35 Sample 32.55 51.88 19.84 32.56 51.97 19.83 Average Mass (g) 19.84 Volume (ml) 25 Density (g/ml) 0.7936 Sample 33.44 52.34 18.90 1 33.45 52.33 18.89 33.46 52.32 18.88 Average Mass (g) 18.89 Volume (ml) 25 Density (g/ml) 0.7556

[0038] The results show that gasoline treated with the method modifies its density by increasing it, which indicates that there is more mass in a certain volume after treatment and this affects performance and combustion since a denser gasoline contains more energy per unit volume and therefore generates more energy.

[0039] Table 4 shows the comparison of the measurement of the viscosity using a Brookfield viscometer.

TABLE-US-00004 TABLE 4 Comparison of the viscosity of the two samples. Sample 1 Treated sample Viscometer constant at 3.82674 10.sup.7 3.49487 10.sup.7 40 C. m.sup.2/s.sup.2 m.sup.2/s.sup.2 Viscosity (Pa .Math. s) 6.94 10.sup.4 7.70 10.sup.4

[0040] The values obtained show an increase in the viscosity of the fuel treated with the method, the value obtained is within normal parameters but corresponds to a fuel of better quality and higher octane. Density and viscosity are variables directly related to fuel quality, and higher viscosity indicates that it contains more energy per unit volume.
