Ben-Gurion University Test LG-X500

The tests that we have conducted to study the rate of reduction of air polluters emitted from diesel engines fitted with Magnetic Fuel Stabilizers of the ALGAE-X 500 type are described hereunder together with their results. We have conducted two series of tests:

Series of Tests with Chassis Dynamometer

1. The test's objective: Testing the rate of reduction of air polluters emitted from a Volvo truck used in garbage disposal, made available for the test by the Transport Department of the Tel-Aviv Municipality.
2. The subject stabilizer was installed on the 5th of November, 2006 between the fuel tank and the primary fuel filter adjacent thereto.
3. The truck was loaded with the assistance of a chassis dynamometer at a "DAN" workshop and the emission rates were measured in three different working regimes. The tests were conducted under the supervision of the signatory.
4. The composition of the exhaust gases was measured at each working regime, once before the stabilizer was fitted (on November 5th, 2006) and again after having fitted it (on December 3rd, 2006). The vehicle traveled between said dates with the fuel stabilizer (the number of kms. shows in the table).
5. During the period of time between both measurements the truck worked as usual and the truck engine did not undergo any treatment (any kind of cleaning, injectors replacement, injection or valves adjustments, filters replacement, oil replacement, etc.).
6. The three different working regimes in which the tests were conducted are detailed in Table Nr. 1.
7. NOx, HC, CO were measured at each regime as well as parameters characterizing the solid particles, namely, the particles' distribution by size and their total mass.
8. The exhaust gases' composition was measured by means of a SUN produce DGA 1000 Gas Analyzer.
9. The parameters characterizing the solid particles were measured by means of a SENSORS produce PM-300 Particulate Analyzer.
10. The results reflect single measurements and are not representative of a statistic sampling collection.

Series of Tests with an Engine Dynamometer

1. The test's objective: Testing the rate of reduction of air polluters emitted from a Ford Transit's engine loaded in this test with a turbulence currents dynamometer.
2. The subject stabilizer was installed on December 27th, 2006, between the fuel tank and the primary fuel filter adjacent thereto. All the tests were conducted on the same day.
3. The engine was loaded with assistance of a turbulence currents dynamometer and the emission rates were measured in three different working regimes.
4. The exhaust gases' composition was measured at each regime in two different protocols: according to the first protocol, at each working regime, the engine was continuously fed by moving the gate valve once thru the engine's normal fuel piping and once thru the magnetic stabilizer. The results are displayed in Table Nr. 2. According to the second protocol, the engine was tested without the stabilizer at three operating regimes one after the other and then it was tested in the same manner and at the same regimes with the stabilizer. The results are displayed in Table Nr. 3.
5. The tests were conducted under the supervision of the signatory.
6. NOx, HC, CO were measured at each working regime as well as the smoke's turbidity and the fuel consumption.
7. The exhaust gases' composition was measured by means of a SUN produce DGA 1000 Gas Analyzer.
8. The smoke's turbidity was tested by means of a SUN produce DG 8000 Smoke Meter.
9. The fuel consumption was measured by weighing fuel at measured times.
10. The results reflect single measurements and are not representative of a statistic sampling collection.

Results of the Series of Tests with a Chassis Dynamometer

1. The stabilizer helped in reducing CO emission by an average rate of 50.4%/ It should be pointed out that, as a rule, the rate of CO emission from diesel engines is very low compared with the emission rate of this component from petrol engines.
2. The HC rate of emission from diesel engines is also low compared with the emission rate of this component from petrol engines. The measured rates were between 2 and 16ppm, therefore they have no practical significance. However, it should be pointed out that except for the medium load test (apparently a measuring error), the average reduction rate is 36.5%.
3. The stabilizer helped in reducing NOx emission by a rate of 12.8%.
4. The stabilizer helped in lowering the level of the particles' emission by a rate of 3.5%.

Results of the Series of Tests with an Engine Dynamometer

1. The stabilizer helped in reducing CO emission by an average rate of 11.1% according to the first protocol and by an average rate of 25.5% according to the second one. As a rule, the rate of CO emission from diesel engines is very low compared with the emission rate of this component from petrol engines.
2. The stabilizer helped in reducing HC emission by an average rate of 5.1% according to the first protocol and by an average rate of 16.2% according to the second one. As a rule, the rate of HC emission from diesel engines is very low compared with the emission rate of this component from petrol engines.
3. The stabilizer helped in reducing NOx emission by an average rate of 13.9% according to the first protocol and by an average rate of 3.3% according to the second one.
4. The stabilizer helped in lowering the smoke emission level by a rate of 15.1% according to the first protocol and by an average rate of 23.4% according to the second one.
5. The stabilizer helped in reducing the fuel consumption by an average rate of 5.5% (9% according to the first protocol and by a rate of 2.0% according to the second one).

Conclusion: From the results obtained from the series of tests described above it can be concluded that the ALGAE-X 500 fuel stabilizer has a contribution in lowering air pollution emitted from diesel engines, including lowering the level of the NOx emitted and the smoke emission rate. From the above results the contribution in the other tested components may also be noted.

Very respectfully,
