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.

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.
