Platinum Gas Saver
New Product Claims To Enable a Gasoline Engine to be
as Fuel Efficient as a Diesel
Design Is the Latest Fuel-Saving Product from National
WASHINGTON, June 27 -- A new design that will enable a gasoline
engine to be as fuel efficient as a diesel engine has just been
awarded patent number 6,907,859 from the U.S. Patent Office,
according to a spokesperson from National Fuelsaver Corporation.
"Every consumer dreams of getting more miles to the gallon,"
comments Joe Robinson, Technical Director of National Fuelsaver
Corp, "but until today a gasoline engine could never compete with
the fuel efficiency of a diesel engine. Our latest design closes
the miles-per-gallon gap."
The newly patented design shows how to manufacture a gasoline
engine with the 16 to 1 power stroke of a diesel engine, while
retaining the 8 to 1 compression ratio of a gasoline engine. The
higher power stroke ratio delivers 8% more miles per gallon, while
the retaining of the compression ratio guarantees the engine's
When this latest design is combined with the company's "Platinum
Gas Saver," a low-cost automotive accessory that has racked up
half a million sales since it appeared on the market, a gasoline
vehicle can be as fuel efficient as the equivalent diesel vehicle.
The Gas Saver adds microscopic quantities of platinum to the air
and fuel that enters the engine. The platinum is the catalyst
which enables the non- burning fuel to burn inside the engine.
Without the Gas Saver, the typical gasoline engine will burn only
68% of each gallon. With the Gas Saver, the engine will burn 90%
of each gallon, a 22% increase.
"Obviously, when 22% more of each gallon burns inside your engine,
22% fewer gallons are required to drive the same distance,"
explains Mr. Robinson. "The savings to the driver is substantial."
After a five year study of the Gas Saver, Federal Consumer
Protection concluded: "Independent testing shows greater fuel
savings with the Gas Saver than the 22% claimed by the developer."
In addition to the fuel savings, the Gas Saver's platinum cleans
out the abrasive carbon to extend engine life and raises octane
levels, making the higher priced gasoline unnecessary for most
Although consumers will have to wait until the company's new
engine design comes to market, the Gas Saver -- which accounts for
most of the fuel savings -- can be easily installed on most
gasoline vehicles today. For further information call

CORP. ASKS: THE CLEAN AIR ACT: TO BE OR NOX TO BE?
BOSTON, Feb. 17 /PRNewswire/ -- The Clean Air Act, legislated to
reduce NOx (nitrogen oxide) emissions from diesel engines and
signed into law by President Bush, just went into effect January
1, 1998. NOx is produced when nitrogen and oxygen from the air are
brought together at the high temperatures of combustion chambers.
Lowering flame temperatures by retarding the timing will decrease
NOx, but will increase soot emissions which is not an acceptable
The only known way to reduce NOx and soot emissions simultaneously
from diesel engines is to add microscopic quantities of platinum
and rhodium to the air and fuel entering the combustion chambers.
The platinum burns the soot to CO2 while the rhodium reduces the
NOx back to nitrogen and oxygen. This is identical to the
chemistry of the catalytic converter in a gasoline vehicle where
the platinum of the catalytic converter burns the CO to CO2, and
the rhodium reduces the NOx back to nitrogen and oxygen.
But, you cannot use a catalytic converter with diesel because the
unburnt fuel is not a vapor like CO. Soot is a solid. The moment
the soot would begin to enter a catalytic converter, the
passageways of the converter would get clogged, and the engine
will stop functioning.
The simple technology of adding platinum and rhodium to the air
and fuel entering an engine was developed by National Fuelsaver
Corp. of Boston and is described in U.S. patent 5,085,841 and in
SAE paper 891634. It applies the platinum and rhodium chemistry of
catalytic converters to the combustion chambers of both gasoline
and diesel engines. In 1979, National Fuelsaver began marketing
their Platinum Gasaver which adds platinum, rhodium and rhenium to
the air and fuel entering a gasoline engine.
The platinum catalyzes the CO to burn inside the engine,
converting this pollutant into 22% more miles per gallon, while
cleaning out the carbon for longer engine life. The rhodium
reduces the NOx and the rhenium raises the octane of the gasoline,
making premium fuel unnecessary.
The vested interests have fought the proliferation of this
technology since 1977 because it reduces fuel consumption
significantly. Since diesel combustion is the one area where there
is no fuel savings with this platinum technology, it will be
interesting to see if the vested interests allow the Clean Air Act
to be or NOx to be.

Method for reduction of
pollution from combustion chambers
February 4, 1992
-- A catalyst
mixture of platinum, rhodium, and rhenium is employed in the
combustion of gaseous, liquid and/or solid fuel in combustion
chambers such as diesel and gasoline engines, for reduction of
pollution emitted from the combustion chambers. The platinum
serves as a catalyst with carbon and carbon monoxide to produce
carbon dioxide, the rhodium serves for reducing oxides of nitrogen
to nitrogen gas and oxygen gas, and the rhenium serves as a
catalytic promoter for the catalytic functions of the platinum and
the rhodium. The rhodium also promotes the catalytic action of the
platinum. The catalytic mixture is introduced into a flame zone of
a combustion chamber in any convenient manner, such as by use of
an air draft. The composition of the mixture is as follows,
namely, 1-9 milligrams of platinum, 0.3-3 milligrams rhodium, and
0.3-3 milligrams rhenium for treating 24 kilograms of fuel.

Diesel Engines by Homogeneous Catalysis of Group Platinum Metals,
The Society of Automotive Engineers, Aug. 1989..
BACKGROUND OF THE INVENTION
The present invention relates to a method for reduction of
pollution emitted from combustion chambers. More specifically the
invention relates to a method for reduction of pollution emitted
from combustion chambers as in diesel and gasoline engines in
motor vehicles and chambers in which combustion of gaseous, liquid
and/or solid fuel takes place. The reduction of pollution is
achieved by rhodium, platinum and rhenium as catalysts.
It is well established that the major pollutants produced by
combustion chambers are soot (carbon), carbon monoxide, and oxides
of nitrogen hereinafter referred to as NO.sub.x.
In recent years attempts were made to reduce pollution in various
ways by using platinum-group catalysts but the results were only
partially successful. In addition rhenium was used in order to
increase the octane number in gasoline instead of using lead.
It became apparent that as combustion temperatures rose, soot and
CO decreased but at the same time NO.sub.x increased, the latter
being an undesirable result. On the other hand, if the combustion
temperature is decreased, the NO.sub.x indeed drops, but the
amount of soot and CO increases, and simultaneously the efficiency
of the fuel utilization drops.
Attempts were made to use platinum as a catalyst for oxidizing the
undesired carbon and the CO to CO.sub.2 in combustion chambers.
(See U.S. Pat. No. 4,295,816). This patent discloses use of the
entire Platinum group for oxidation purposes, but refers primarily
to platinum. Over the last decade platinum has been used as a
homogeneous catalyst to oxidize C+CO to CO.sub.2 in both engines
However, the problem remained as to how to reduce the NO.sub.x
chemically to the gases N.sub.2 and O.sub.2, this being an
SUMMARY OF THE INVENTION
The purpose of the present invention is to oxidize the carbon and
the carbon monoxide to CO.sub.2 and simultaneously to reduce the
NO.sub.x to N.sub.2 and O.sub.2 without one process being at the
expense of the other.
According to the present invention the catalyst mixture is
comprised of platinum, rhodium and rhenium. Wherein the platinum
serves for oxidizing the carbon and CO to CO.sub.2, the rhodium
serves for reducing the NO.sub.x to N.sub.2 and O.sub.2, and the
rhenium serves as a catalytic promoter for the catalysts platinum
and rhodium. The rhodium also promotes the catalytic action of the
The rhenium enables the platinum and rhodium to fulfill their role
optimally. A defined ratio must be maintained among the catalysts
and between the quantities of catalysts and fuel.
The site at which said simultaneous oxidation and reduction takes
place is the combustion chamber to which the catalysts are
transported by various means. See for example U.S. Pat. Nos.
4,295,816 and 4,475,483.
The present invention relates to a method for reducing the
pollution emitted from combustion chambers by the addition of the
catalysts-platinum, rhodium and rhenium to the combustion chamber
in specific proportions and in a specific ratio to the amount of
The introduction of the above mixture of catalysts into the
combustion chamber leads to a simultaneous oxidation and
reduction; Oxidation of carbon and CO to CO.sub.2, and reduction
of the NO.sub.x to N.sub.2 and O.sub.2.
According to the present invention the following amounts of
catalysts should be used; 1-9 mg platinum, 0.3-3 mg rhodium and
0.3-4 mg rhenium per 24-2400 kg fuel. Optimally the following
quantities should be used: 3.2 mg platinum, 1 mg rhodium, and 1 mg
rhenium per 240 kg fuel.

The reduction of pollution by simultaneous oxidation and reduction
can occur only when the specific proportions among the components
of the system are maintained.
Preparation of the catalyst
A mixture of 160 gr. platinum, 50 gr. rhodium and 50 gr. rhenium
suffices to reduce pollution in 12 million liter fuel.
The mixture is prepared as follows:
400 gr. H.sub.2 PtCl.sub.6.6H.sub.2 O (CPA) in water
120 gr. Rdcl.sub.2 in water
50 gr. rhenium in perrhenic acid in a total of 114 liters of
In order to reduce pollution in engines or furnaces by means of
the equipment and method described in the above-mentioned U.S.
patents, the catalytic mixture described above is divided into
6000 vials wherein each vial contains 19 ml liquid. Each such vial
can reduce the pollution of 2000 liters of fuel in combustion
Up to the present, for reduction of pollution in combustion
chambers 500 gr. of H.sub.2 PtCl.sub.6.6H.sub.2 O (CPA) has been
used, without any addition of rhodium.
Although the U.S. Pat. No. 4,295,816 relates to the platinum-group
metals for the reduction of pollution, it does so only with regard
to the oxidation process of the carbon and the CO to CO.sub.2 and
does not relate to the rhodium and its function in the reduction
of the NO.sub.x.
FIG. 1 shows a reduction of the CO and NO.sub.x pollution in
diesel engines in a motor vehicle. Prior to the injection of the
catalytic mixture, the pollution level was measured as NO.sub.x
1000 ppm and CO 350 ppm. Subsequent to the injection of the
catalytic mixture, a significant reduction was noted in the
NO.sub.x level which dropped to 500 ppm and the CO level which
dropped to 200 ppm.
FIG. 2 shows the decrease in pollution in two motor vehicles as a
result of the injection of the catalysts mixture wherein the
pollution was examined with regard to NO.sub.x and opacity. In one
vehicle opacity declined from 73% to 8% and in the other from 50%
to 5%. In the first vehicle the NO.sub.x dropped from 1600 ppm to
300 ppm, and in the second vehicle from 2000 ppm to 200 ppm. It
should be noted that in the first vehicle the decrease in
pollution was examined after 1845 miles after injection, and in
the second--after 3203 miles.
FIG. 3 shows the decrease in pollution in three additional motor
vehicles. The pollution test was conducted in the first vehicle
6538 miles after injection, and in the second vehicle--4925 miles
after injection, and in the third vehicle--1311 miles after
injection. In the first vehicle opacity decreased from 84% to 9%
and the NO.sub.x decreased from 800 ppm to 250 ppm. In the second
vehicle opacity decreased from 30% to 9% and the NO.sub.x from 600
ppm to 100 ppm, and in the third vehicle opacity decreased from
72% to 7% and the NO.sub.x from 800 ppm to 300 ppm.
FIG. 4 refers to the decrease in pollution examined 66 6538 and
9302 miles respectively after the injection and immediately after
another injection. After 66 and 6538 miles the NO.sub.x dropped
from 800 ppm to 300 ppm and 250 ppm respectively, and the opacity
dropped from 84% to 4% and 9% respectively. 9302 miles after
injection a dramatic increase in pollution was noted due to the
fact that no more of the catalytic mixture remained. A second
injection and reexamination indicated an immediate and sharp drop
in the pollution level. The NO.sub.x dropped from 1200 ppm to 380
ppm and opacity from 78% to 25%.
You see them at your local auto parts store or advertised on late
night television. We're talking about devices or chemicals that
claim to improve your fuel economy and save you hundreds of
dollars in the process. And with gas prices above $4 a gallon in
some parts of the country, why not invest in a system that will
There are scores of touted fuel savers on the market, all with
claims to save you big loot on your gasoline bills. They go by
catchy names like "Auto Miser," "Cyclone-Z," "Magna Flash Ignition
Control System," "Platinum Fuel Saver," "Fuel Genie," and "Tornado
Fuel Saver." There's even one device called the "Pre-Ignition
Catalytic Converter (PICC)" that, in the company's words, "will
increase the mileage of all personal vehicles to over 100 miles
per gallon (city or highway). There are testimonials on the
homepage for this device from an owner of a 2006 Mazda3 who is
excited to now get 121 mpg after installing the PICC system.
Another claims his Ford cargo van gets 43 mpg. By the way, before
you spend several thousand dollars for the PICC, you must first
buy the Hydrogen Assist Fuel Cell (HAFC) for just over $1,000.
Prices range widely for these gizmos, from a few dollars for fuel
additives that purport to save fuel, to several hundred dollars
for more advanced systems.
But do these devices really work?
For answers, we sought expert opinion. The federal government's
Environmental Protection Agency (EPA) has tested nearly 100 "fuel
savers" over the years and found no significant improvement in
fuel economy with any additive or device, according to tests
posted on its website, www.epa.gov
Consumer Reports (CR), an independent, consumer-oriented testing
firm, also evaluated myriad devices. We spoke with David Champion,
senior director of CR's Auto Test Center, who said: "you can do
more to improve fuel economy by the way you maintain and drive
your vehicle then any of these ‘gas savers' will ever achieve."
Champion singled out the Platinum Gas Saver as typical of
The Platinum Gas Saver ($248 for two) is marketed by the National
Fuelsaver Corp. and its ads claim up to 22 percent gains in
economy. National Fuelsaver says that the product adds microscopic
amounts on platinum to the air and fuel going to the engine,
making the vehicle burn fuel more efficiently.
National Fuelsaver says the device may take up to 1,800 miles
before it is fully effective, and you may have to advance engine
timing or install new oxygen sensors for the system to work
properly. According to CR, these actions alone may improve economy
without purchasing any additional equipment.
In tests, Consumer Reports saw no improvement in economy after 500
miles of testing. They even replaced all four oxygen sensors in
one of the test vehicles to the tune of $748, even though the
vehicle was new and did not need sensor replacement. "Magnets,
atomizers, vortex generators - none of them work, said Champion.
In fairness to the many companies that may have products with
promise that may have not yet been tested, including the PICC and
HAFC, do your own research.
We did find one product that made us more aware of our "fuelish"
ways behind the wheel. It's called the Scan Gauge II Automotive
Computer, and uses the OBD-II port found on every vehicle built
since 1996 to monitor various engine parameters.
The Scan Gauge II retails for $169.99 and is extremely easy to
install. Find a suitable location on your dash or console (away
from airbags!) for the small, 5-inch wide, 1-inch deep unit. Route
the supplied cable to the OBD-II port (usually under the dash),
and perform simple calibrations by inputting information such as
the capacity of the gas tank, vehicle weight, and so forth - all
data that can be found in your owner's manual.
In addition to displaying engine speed, vehicle speed and reading
and resetting "check engine light" fault codes that may develop,
the Scan Gauge II is a full trip computer with readouts for things
like fuel economy, gallons of gas used and distance to empty. It
can also display battery voltage, coolant temperature, air intake
temperature and other important measurements.
On a trip to Richmond, Virginia from Maryland, I installed the
Scan Gauge in a 1997 Volvo 960. On the trip south, I averaged 26.3
mpg at an average speed of 62 mph. I disconnected the unit for the
return trip and averaged 22 mpg at about 70 mph. Using the unit
was fun, as four parameters can be displayed at one time, and
proved to me that perhaps the biggest fuel saver of all is
sensible driving - when you are aware of what you are doing, you
can do something about it. I kept my speed near the limit, and
saved more than four miles per gallon and possibly a ticket in the
process. If your vehicle is not equipped from the factory with a
trip computer, the Scan Gauge II or similar trip computer is a
worthy, money-saving device. (www.scangauge.com)
