NATIONAL INSTITUTE OF BCOLOGIA                                             FORMS CG-1A MAIN DIRECTORATE OF MANAGEMENT ENVIRONMENTAL DOO - 900 - 115 City of Mexico, D.F., to 6 of March of 1996 KENNETH L. DAVIS S.V. TECHNOLOGIES, INC.. 558 BIRCH STREET, BUILDING #3 LAKE ELSINORE, CALIFORNIA 92530 U.S.A.           By this conduit I allow myself to send to you, the obtained results derivatives of the evaluation tests asked for you, for the device demanded " Econovalve EC-1 ".           Object of the tests conducted to the mentioned device, was the evaluation of the immediate effect as far as the discharge of the proven polluting agent and gas discharge of the escape of the automobile vehicle in circulation.           The tests, were made in the Laboratory of Vehicle Emissions of the INE, following a test certificate previously established, for to as I am used dynamometer of maca chassis Clayton. The gas current emitted, was collected and analyzed in a bank of annalistic sampling of diluted gases Horrible mark, being related to the this series of tests following ones: Carbon Monoxide, Hydrocarbon and Nitrogen Oxide, like the determination of the yield in the fuel.           The development of the evaluation tests, was according to the procedure established in Norm NMX-DGN-AA-11-1980, the tests were carried out in two vehicles whose marks and characteristics are similar to continuation: Vehicle # 1: Dodge Pick Up, model 1993, motor one of 8 cylinders with manual transmission of 4 speeds. Vehicle # 2: Chrysler Spirit, model 1991, motor one of 4 cylinders with automatic transmission. Results: Vehicular #1 CO HC NOx Yield grams/Kilometro Km/1 Line Bases 25.39 1.90 1.06 4.94 With Device 26.54 1.91 1.01 5.58 Difference + 1.15 + 0.01 - 0.05 - 0.64 % of Variation + 4.33% + 0.52% - 4,"95%" +11.47% Vehicle #2 CO HC NOx Yield grams/Kilometro Km/1 Line Bases 6.03 0.16 1.64 7.90 With Device 3.18 0.09 1.42 10.04 Difference - 2.85 - 0.07 - 0.22 + 2.14 % of Variation - 47.26% - 43.75% - 13.41% + 21.31%          Commentaries:           Derivative of the analysis of the results obtained when using the device " Econovalve EC-1 " is very observed a behavior dissemble in the effect on the emissions of Carbon Monoxide, Hydrocarbon and Nitrogen Oxide,.           It is important to remember, that the obtained distinctions, were product of an immediate effect since not effected a route of the vehicles between test and test, reason why the variation is not known that could have the effect in if, in the same way, the durability of the same one. As it is of his knowledge, the present does not represent a recommendation of the product before mentioned. To T And N T A.m. And N T E EFFECTIVE SUFFRAGE, NONCRE-ELECTION THE CHIEF OF A MAIN DIRECTORATE SIGNED DR ADRIAN FERNANDEZ BREMAUNTZ c.c.p. C. Ing.
