Inventor
: Liquid boosts mileage, reduces pollution
by Thom
Jensen and KATU Web Staff

A southern Oregon inventor claims he has developed a way to not
only save you money at the pump but also reduce air pollution.
"We've come up with a solution to get all of the fuel to burn
efficiently," said the inventor, Bob Kurko. "If you get all of
the fuel burning, you're not going to have emissions."
Kurko, pictured below, said he invented E3 ultra clean fuel
catalyst in his garage in Cave Junction.
He said it changes the way gasoline is used in the engine,
making it burn 100 percent efficiently.
Kurko said your car would actually act as an air cleaner. When
the air from the outside is pulled in through the air intake
system, through the filter and then mixed in the engine with the
gasoline and the fuel catalyst, what's burned and comes out of
your tail pipe is actually cleaner than the air that went in to
your engine.
Lt. Col. James Boozell said he is a believer.
"If every car in the country were driving on this, global
warming would be eliminated," said Boozell, who is a Department
of Defense employee at the Pentagon while moonlighting as a
spokesman for Kurko's E3 fuel catalyst.
He said he has to fight his own bosses and oil companies to make
them listen.
"Unless they are directed to use the product, they are not going
to voluntarily use the product … so it may take some sort of
directive for all of our fuel companies and our large government
agencies to come on board," said Boozell, pictured at right.
He said he became a believer when he ran the product in diesel
engines at the South Carolina National Guard.
Some of the vehicles - including Hummers and large
two-and-a-half ton trucks - saw fuel efficiency increase 45
percent and emissions drop 98 percent, Boozell said.
KATU reporter Thom Jensen tested the catalyst in his own car.
First he ran his family's sport utility vehicle on regular
gasoline. After burning through a tank of fuel, his vehicle's
onboard computer showed an average gas mileage of 18.2 mpg.
Then he filled up again and added a quart of the E3 catalyst and
ran the SUV under his usual driving conditions. The computer
showed he was getting almost 22 mpg.
This was far from a scientific test – such a lab test would cost
hundreds of thousands of dollars.
So we asked Portland State University chemistry professor
Shankar Rananavare what he thought about our results.
He said the gas mileage probably comes from a cleaner burning
engine. Rananavare said the fuel catalyst may really be a fuel
system cleaner.
"There's nothing inherit in that material that gives you extra
energy," the professor said.
His preliminary conclusion, he said, is only based on KATU's
description of the product. The actual materials used in the
catalyst have not been made public.
Rananavare said he wants to see more tests done in lab
conditions with new car engines burning the same brand of fuel.
He said tests should be done repeatedly with results that are
also repeated before you can truly say the catalyst works.
We also put Kurko's emissions claims to the test.
The reporter tested his 2004 Volvo at Morgan Automotive in
southeast Portland on a four-gas analyzer.
It ran super clean before the additive, with hydrocarbons at
just 8 ppm (parts per million) and carbon monoxide at zero –
which is clean enough to pass the strictest emissions
requirements in the U.S.
With the fuel additive, there were no hydrocarbons (pictured at
right), which is not unheard of but not seen often, according to
those at the shop.
Kurko said that so far government agencies and oil companies in
the U.S. have had the same response to his invention.
"They laugh at us," he said.
As gas prices soar, though, Kurko said the laughing is beginning
to stop and suitors are lining up, mostly in other countries.
"I'm gonna go where they want it, so if they don't want it here
in America that's fine," Kurko said. "We'll go other places."

CROSS-REFERENCE
TO RELATED APPLICATIONS
This application claims benefit of U.S. Provisional Patent
Application No. 61/127,707, filed on May 15, 2008, and entitled
“ULTRA CLEAN FUEL CATALYST”.
FIELD OF
THE INVENTION
The present disclosure relates to catalysts for use as additives
to fossil fuels. More particularly, the present disclosure
relates to fuel additives that will substantially eliminate
harmful greenhouse gas emissions while providing an increase in
fuel efficiency during fossil fuel combustion.
BACKGROUND
OF THE INVENTION
Over the last century, the widespread use of liquid fossil fuels
as resulted in substantial industrial progress. Notwithstanding
current efforts to conserve the world's petroleum resources and
to use alternative energy sources such as coal, nuclear, solar,
geothermal, and the like, fuel obtained from oil remains our
main energy source for everything from vehicles and home heating
plants to our largest industrial facilities.
As its use has increased, fossil fuels such as oil, has been the
source of much industrial and urban pollution. For example,
during combustion, incomplete combustion of the fuel produces
toxic carbon monoxide and other harmful emissions. The electric
spark and high temperatures also allow oxygen and nitrogen to
react and form nitrogen monoxide and nitrogen dioxide, which are
responsible for photochemical smog and acid rain. Furthermore,
though once very abundant and inexpensive, oil has recently
become a very expensive commodity and, because it is a
non-renewable resource, oil will become ever more scarce in the
future. Our use of it is so universal that even the most
optimistic predictions of achieving transition to alternatives
forecast many years of high consumption.
Accordingly, efforts have been directed to improving the
performance of machinery using fossil fuels or liquid
hydrocarbon fuels, for example, by increasing the miles per
gallon of automobiles. In part this has involved redesign of the
machinery which uses the fuel. Another tactic has been to change
the combustion characteristics of the fuel itself by refining
and by the use of additives. Although there have been
substantial efforts made to improve hydrocarbon fuels by
supplementing them with various additives, these efforts have
not enjoyed widespread acceptance or much success because of one
shortcoming or another. Accordingly, there has long been, and
still remains, a need for an inexpensive yet effective additive
for liquid fossil fuels to provide cleaner combustion and fuel
improve efficiency. It would be desirable to utilize fuel
additive that, when added to fossil fuels, uses less fuel,
produces reduced emissions while maintaining the same BTU output
during combustion. It is a primary object of my invention to
provide such a fuel additive.
SUMMARY OF
THE INVENTION
An additive composition for use in a liquid fuel containing a
mixture of alcohol, aromatic hydrocarbon, acetone, petroleum
ether, and mineral oil. The fuel additive is added to a
hydrocarbon fuel to reduce pollutants and improve burning
efficiency of the fuel. The treated fuel is produced by mixing a
sufficient amount of additive to the fuel to produce the desired
result.
DESCRIPTION
OF THE INVENTION
I have developed a new additive composition, used to treat
liquid fuels, comprising various mixtures of ingredients. One
ingredient is alcohol. Preferably I use a low molecular weight
alcohol, that is, an alcohol having four or fewer carbon atoms.
Such alcohols include methanol, ethanol, propanol, isopropanol,
butanol, and mixtures thereof. The alcohol will comprise, on a
volume/volume basis at ambient temperature, about 62 to about 82
percent of the additive, preferably about 70 to about 75
percent. For additives for gasoline, I typically use ethanol and
for gasohol I prefer isopropanol.
A second ingredient of the additive is an aromatic hydrocarbon.
Preferably I use benzene or a benzene derivative such as
toluene, xylene, naphthalene, biphenyl and mixtures thereof. The
aromatic hydrocarbon will comprise, on a volume/volume basis at
ambient temperature, about 5 to about 15 percent of the
additive, preferably about 8 to about 10 percent.
A third ingredient of the additive is acetone which is an
organic compound with the formula OC(CH3)2 also known as
dimethyl ketone, DMK, or propanone. The acetone will comprise,
on a volume/volume basis at ambient temperature, about 5 to
about 15 percent of the additive, preferably about 8 to about 10
percent.
A fourth ingredient of the additive is petroleum either that
includes a group of various volatile, liquid hydrocarbon
mixtures of non-polar solvents known as benzine, VM&P
Naphtha, Naphtha ASTM, Petroleum Spirits, X4, or Ligroin. The
petroleum ether will comprise, on a volume/volume basis at
ambient temperature, about 5 to about 20 percent of the
additive, preferably about 7 to about 12 percent.
A fifth ingredient of the additive is mineral oil or liquid
petroleum is a by-product in the distillation of petroleum to
produce gasoline another petroleum based products from crude
oil. It is composed mainly of alkanes, typically 15 to 40
carbons, and cyclic paraffin, related to white petroleum. The
mineral oil will comprise, on a volume/volume basis at ambient
temperature, about at least 0.00001 percent of the additive,
preferably about at least 0.000015 percent.
In practice to treat the desired fuel, I first blend the
ingredients in for example a 55 gallon drum at room temperature
to produce an additive according to my invention. I then
introduce, by splash blending for example, the additive in
sufficient quantities to the fuel to improve the efficiency with
which the fuel burns or operates in an engine or its other
operating characteristics. The amount which will provide optimum
results can vary depending upon the type and quality of the
fuel, engine or burner design and the like.
Regarding specific fuels to be treated, I have found, for
example, that by mixing my fuel additive to gasoline or gasohol
fuel in a ratio of about 0.25 to about 4.0 ounces of additive to
about one gallon of fuel produces superior results. For diesel
fuel for use with cars, trucks, trains, marine and small
engines, and the like, I prefer to use a ratio of about 1.0 to
about 5.0 ounces of additive to about one gallon of fuel. For
diesel fuels such as heating oil or as smudge pot fuel, I have
found that I obtain better results by using a ratio of about
0.25 to about 3.0 gallons of additive to about 32 gallons of
fuel.
For bunker fuels, before introducing my additive, I generally
preheat the bunker fuel above ambient temperature, typically
using higher temperatures for heavier bunker fuels to provide
ease of blending in the additive. Typical bunker fuels include,
without limitation, #2, #4, #6, and #8 bunker fuels used in
marine and industrial boilers. Depending on the type of bunker
fuel, I typically use a ratio of about 0.25 to about 3.0 gallons
of additive to about 30 to 40 gallons of bunker fuel.
For recycled fuel oil used in place of diesel in industrial
boiler for example, before introducing my additive, I generally
first clean the fuel by standard methods including centrifuging
or passing it through a filter. I then heat the cleaned fuel
above ambient temperature to facilitate ease of blending with
the additive. I prefer to use a ratio of about 0.25 to about 3.0
gallons of additive to about 40 gallon of recycled fuel oil.
EXAMPLES
Having described my invention, I now provide the following
examples to illustrate specific applications of my invention,
including the best mode now known to perform the invention. I do
not intend for these examples to limit the scope of my invention
as I have described in this application.
Example 1
Treatment of Gasoline
Additive Formulation #1 is provided for treatment of gasoline
(without ethanol added to the fuel) for use with cars, trucks,
recreation vehicles and small engines that burn gasoline. Into a
standard 55 gallon drum at ambient temperature, was blended
40.15 liquid gallons or 73% of total volume of 55 gallon
container of tech grade ethyl alcohol C2H5OH., 4.95 liquid
gallons or 9% of total volume of 55 gallon container of tech
grade Acetone OC(CH3)2, 4.95 liquid gallons or 9% of total
volume of 55 gallon container of tech grade Xylene C8H10, 4.95
liquid gallons or 9% of total volume of 55 gallon container of
tech grade VM&P Naphtha, composition of C8 C9, 5 liquid
milliliters or 0.000024% of total volume of 55 gallon container
of Hydro treated Distillate light Naphthenic Oil. The components
are blended through splash blending.
Additive Formulation #1 is then introduced into the gasoline at
ambient temperature blending one ounce of the additive to one
gallon of gasoline fuel by splash blending.
The resulting treated gasoline was then tested for physical
properties in a 2002 Acura MDX, with a 3.5 L. V. Tech. engine
using regular gas having the additive. Prior to commencing the
test on Apr. 23, 2007 the vehicle had 47,228 miles and was
averaging 19.63 miles per gallon and the emissions at idle were
HC 24 PPM, CO2 15.5%, CO 0.01%, O2 0.0% and NOx 2 PPM. The time
frame for the test was four months using Formulation #1 each day
and the results were recorded periodically.
The driving conditions during the approximate four month test
period with 4062 miles driven were substantially the same as the
conditions prior thereto. The emission tests were conducted with
a Ferret Gas link II, and a Snap-on 5 gas emissions analyzer.
Both analyzers were calibrated by a certified mechanic.
During the test period the MPG increased to an average of 23.12
from 19.63 or an increase of 3.49 MPG or 17.8%. The emissions at
idle decreased to HC 0 PPM or 100%, CO2 14.4% or 7.09% decrease,
CO 0.01% to 0.0% or 100% decrease, O2 0.0% to 0.13% or an
increase of 0.13 from a base of zero, and NOx 2 PPM to 0 PPM, a
100% decrease. The emissions at 2500 RPM's decreased from 101
PPM HC to 3 PPM HC or 97% decrease, CO2 from 15.6% to 14.5% or a
7% decrease, CO 0.01% to 0.0% or 100% decrease, O2 0.0% to 0.18%
or an increase of 0.18 from a base of zero, and NOx 101 PPM to
58 PPM, a 42% decrease.
Example 2
Treatment of Gasohol
Additive Formulation #2 is provided for treatment of gasoline
with ethanol fuel (sometimes referred to as “gasohol”) for use
with cars, trucks, recreation vehicles and small engines that
burn gasoline. Into a standard 55 gallon drum at ambient
temperature, was blended 40.15 liquid gallons or 73% of total
volume of 55 gallon container of tech grade Isopropyl alcohol
C3H7OH, 4.95 liquid gallons or 9% of total volume of 55 gallon
container of tech grade Acetone OC(CH3)2, 4.95 liquid gallons or
9% of total volume of 55 gallon container of tech grade Xylene
C8H10, 4.95 liquid gallons or 9% of total volume of 55 gallon
container of tech grade VM&P Naphtha, composition of C8 C9,
5 liquid milliliters or 0.000024% of total volume of 55 gallon
container of Hydro treated Distillate light Naphthenic Oil. The
components are blended through splash blending.
Formulation #2 is introduced to the gasohol at ambient
temperature blending one ounce of additive to one gallon of
gasoline fuel by splash blending. The resulting treated gasohol
was then tested for physical properties in a 2002 Acura MDX,
with a 3.5 L. V. Tech. engine using regular gas having the
additive. Prior to commencing the test on Aug. 25, 2007, the
vehicle had 52,411 miles and was averaging 19.63 miles per
gallon and the emissions at idle were HC 24 PPM, CO2 15.5%, CO
0.01%, O2 0.0% and NOx 2 PPM. The time frame for the test was
three months using the fuel catalyst each day and recording the
results periodically.
The driving conditions during the approximate three month test
period with 6326 miles driven were substantially the same as the
conditions prior thereto. Formulation #2 was used each day and
the results were recorded periodically. The emission tests were
conducted with a Ferret Gas link II, and a Snap-on 5 gas
emissions analyzer, both analyzers were calibrated by a
certified mechanic.
During the test period the MPG increased an average of 1.58 from
a base average of 19.63, an increase of 1.58 MPG or 8.03%. The
emissions at idle decreased to HC 0 PPM or 100%, CO2 from 15.5%
to 13.6% or 13.8% decrease, CO 0.01% to 0.0% or 100% decrease,
O2 0.0% to 0.2% or an increase of 0.2 from a base of zero, and
NOx 2 PPM to 17 PPM, an increase of 15 PPM. The emissions at
2500 RPM's decreased from 101 PPM HC to 0 PPM HC or 100%
decrease, CO2 from 15.6% to 14.5% or a 7% decrease, CO 0.01% to
0.0% or 100% decrease, O2 0.0% to 0.1% or an increase of 0.1
from a base of zero, and NOx 101 PPM to 76 PPM, a 25% decrease.
Example 3
Treatment of #2 Diesel Fuel
Additive Formulation #2 was prepared as described in Example 2
for use with cars, trucks, trains, marine, and small engines
that burn #2 diesel. Formulation #2 is introduced to the #2
diesel at ambient temperature blending three ounces of
Formulation #2 to one gallon of #2 diesel fuel by splash
blending.
The resulting treated #2 diesel fuel was then tested for
physical properties in a 2000 Argosy Freightliner, with a diesel
Caterpillar C12 410 HP motor with a five inch stack that powered
the tractor unit on the Semi Truck. Prior to commencing the test
on Aug. 10, 2008 the vehicle had over 500,000 miles on the
chasse with a rebuilt engine. The truck was averaging 5.81 miles
per gallon and the emissions without treatment averaged 49.25%.
The time frame for the test was four months using the fuel
catalyst each day and the results were recorded periodically.
The driving conditions during the four month test period with
over 25,000 miles driven were substantially the same as the
conditions prior thereto. We used a Wagner digital smoke meter
model 6500 and preformed (4) snap tests on the unit with the
Formulation #2 and (2) two snap tests without treatment. The
snap test consists of three max revs of the engine and an
average is taken of the three snaps for one opacity percentage.
The opacity meter reads the maximum smoke density from revving
the engine or (snap).
During the test period the MPG increased to an average of 7.29
MPG from 5.81 MPG. This was a 1.31 MPG increase or 20.37%. The
density of the emissions from opacity tests of the smoke
decreased substantially using Formulation #2 from an average
49.25% without treatment to 2.95% using Formulation #2.
Example

Treatment of Heating Oil
Additive Formulation #2 was prepared as described in Example 2
for use with use with #2 diesel fuel for use as heating oil in
“smudge pots” for orchard heating that burn #2 diesel.
Formulation #2 is introduced to the #2 diesel at ambient
temperature blending one quart of the Formulation #2 to eight
gallons of #2 diesel fuel by splash blending.
The resulting treated heating oil was then tested for physical
properties in two separate tests. The tests were with Myers
Orchard, Talent Oregon and Harry and David Orchards, Medford
Oregon. The test with Myers was conducted two times for visible
particulate smoke, during the winter and spring of 2008. This
same time period, Mr. Myers tested the product for fuel
efficiency when he used the fuel catalyst in #2 Diesel to heat
his orchard. Both tests also used identical smudge pots of
similar condition and made by same manufacturer. The test with
Harry and David during the winter and spring of 2008, testing
the product for emissions and particulates left on leaves after
using the smudge pots for heating. Harry and David to certify
their fruit as organic needed a product that would not leave
smoke residue from smudging using #2 diesel.
During the test period, Mr. Myers stated that using the
Formulation #2 in #2 diesel gave him cost savings from
efficiency gains in extending burn time of the fuel. The two
tests for visible smoke particulates show little or no visible
particulates using the fuel catalyst compared to very dense,
thick smoke in #2 diesel without the fuel catalyst. Local
Medford Oregon TV station channel 5 News did a report on the
results verifying no visible smoke emissions from #2 diesel
treated with Formulation #2. Harry and David used cotton swabs
to swab buds and leaves of fruit trees during the test period
and reported no particulate residue on swabbed tree growth after
smudging using Formulation #2. Without treatment, Harry and
David reported particulate residue that would have disqualified
them from certifying their fruit organic smudging with #2 diesel
without treatment.

Treatment
of Bunker Fuel
Additive Formulation #2 was prepared as described in Example 2
for use with use with #2 diesel fuel for use with #2, #4, #6, #8
bunker fuels for use in marine and industrial use boilers.
Formulation #2 at ambient temperature is introduced into the #2
bunker fuel heated to 110 degrees Fahrenheit, blending one
gallon of the Formulation #2 to forty gallons of #2 Bunker fuel
by splash blending. Formulation #2 at ambient temperature is
introduced into the #4 bunker fuel heated to 125 degrees
Fahrenheit, blending one gallon of the Formulation #2 to thirty
five gallons of #4 Bunker fuel by splash blending. Formulation
#2 at ambient temperature is introduced into the #6 bunker fuel
heated to 145 degrees Fahrenheit, blending one gallon of the
Formulation #2 to thirty gallon of #6 bunker fuel by splash
blending. Formulation #2 at ambient temperature is introduced
into the #8 bunker fuel heated to 160 degrees Fahrenheit,
blending one gallon of Formulation #2 to thirty gallons of #8
bunker fuel by splash blending.
Bunker fuels treated with Formulation 32 have not been tested.
The densities of bunker fuels are similar to the Recycled Fuel
Oil (“RFO”) that has been tested. I believe therefore that the
bunker fuels will have similar results as the RFO tests. RFO was
tested for physical properties in two 350,000 BTU Boilers at a
RFO plant. The time frame for the test was four months using the
fuel catalyst each day and recording the results periodically.
The test period began April of 2008 and continued through July
2008. The time frame for the test was four months using the
Formulation #2 each day and recording the results periodically.
During the test period the volume of fuel used in a twelve hour
period of burn time was reduced from approximately 125 gallons
to 85 gallons, a reduction of 32%. The boiler operators reported
better ignition starts, no ignition failures, a hotter burn with
less ash and a cleaner burn. The maintenance time was extended
from 400 hours to 575 hours with no carbon buildup in stack or
ignition system or nozzles, reducing maintenance costs.

Treatment
of Recycled Fuel Oil
Additive Formulation #2 was prepared as described in Example 2
for use with Recycled Fuel Oil (RFO), for use in place of #2
diesel fuel and in industrial use boilers. This is a process
that first takes RFO and cleans the oil by use of a two micron
filter or centrifuge. The cleaned RFO is then heated to 140
degrees Fahrenheit and is blended with the fuel catalyst.
Formulation #2 at ambient temperature is splash blended using
one gallon of Formulation #2 to forty gallons of the heated RFO.
The treated RFO makes an economical, ultra clean fuel with
significant higher BTU's which is used in boiler applications
and substitutions for #2 diesel fuels.
The resulting treated RFO was then tested for physical
properties in two 350,000 BTU Boilers at a RFO plant. The time
frame for the test was four months using the fuel catalyst each
day and recording the results periodically. The test period
began April of 2008 and continued through July 2008. The time
frame for the test was four months using the fuel catalyst each
day and recording the results periodically.
During the test period the volume of fuel used in a twelve hour
period of burn time was reduced from approximately 125 gallons
to 85 gallons, a reduction of 32%. The boiler operators reported
better ignition starts, no ignition failures, a hotter burn with
less ash and a cleaner burn. The maintenance time was extended
from 400 hours to 575 hours with no carbon buildup in stack or
ignition system or nozzles, reducing maintenance costs.
