"Vapster was validated by a third party witness from a nationally
recognized laboratory on Feb. 9, 2007. Four tests were run with Vapster
and four control tests were conducted without. Vapster averaged 42.2 mpg whereas
the control averaged 32.8 mpg. The tests were conducted on level highways
between Ft. Lauderdale and Ft. Meyers, FL. The road tests were conducted
at 65 mph and used a calibrated one gallon volume of gasoline.
"The test results are included as two attachments [below]. We would
like to thank the general public for interest in our device. We are
entertaining financial interests in our project. Again thank you for
letting the world know about real fuel saving devices that can save money at the
gas pump and help the environment with less air pollution."

"We are attempting to get third party witness testing for our
prototype. We would like to open the testing to qualified individuals,
engineers, Universities, scientists, etc. to witness and document our
findings. We have been testing close to a year and would like to confirm
our tests. Last month's tests have been in the 40+ mpg range versus 30.5
mpg for the control. I live in the south Florida area and would like to
arrange for witness testing as soon as possible." -- Gerald

The testing is being tested with a fuel injection engine on a straight
road course. The tests are run 100 miles in one direction and 100
miles in opposite direction on the same highway.
The tests are run by putting one gallon of gas into a separate fuel tank
(3 gal total volume) until the car runs out of gas. The car is
driven at 65 mph throughout all the tests. The distance and time
is recorded. Any other items I should be aware of please let me
know.

Overview
Patented
device by Gerald Rowley replaces standard fuel injection system and carbureted
systems for gasoline engines. Working prototype averages 40% less fuel
consumption over a conventional fuel delivery system. In discussion with
several interested parties to bring to the market.
The device is a bolt-on device which can be engineered to fix any size
gasoline engine. The existing fuel delivery system can remain in place until
the operating temperature of the VAPSTER is achieved which is in the range of
275F to 310F. When the optimum temp. is achieved the original fuel
system is shut off and the VAPSTER system takes over. The system is
designed for engines which run all day at a fixed RPM.
The device introduces the high octane fuel mixture into the air intake of
the engine. So it doesn't matter if an engine has fuel injection or
any other fuel system. It uses heat from the exhaust to heat the fuel
and the mixture is passed through a throttle body which reduces the air a
normal engine would use. The mixture is very lean so only 1/3 to 1/2
the amount of air is needed for combustion. So not only do you
save fuel but air/oxygen. I know it is not the complete answer to the
energy crisis but it would help enormously in reducing our oil import
situation.
The tested design calls for an engine to run at a constant RPM so it would
be best suited for hybrid engines, generators, pumping stations, generating
plants, tractors, farm equipment, boat engines, etc. The device has a
slowing mechanism built into the patent design by introducing misted
water. But, this engineering requires money for further testing.
Patent
Abstract: A fuel vaporization and mixing system is provided for
producing a mixture of fuel vapor, atomized water and air for delivery into an
internal combustion engine, the system being configured and positioned relative
to the internal combustion engine to draw heat from the engine exhaust system to
vaporize fuel for combining into the mixture.
History
I have built over twenty prototypes over a ten year period. I lost
interest in my project is the late 1980's due to personal reasons.
However, I jumped back on the project several years ago pursuing a patent on the
best developed prototype. Earlier this year the prototype was built and
several weeks of testing to tweak the device provided good results. I have
been testing the device for over six months with no mechanical failures.
The device is safe as materials are stainless steel. The heating chamber
used is over 10 years old which was used in an earlier prototype. The
system operates on a very low pressure system 1-2 lbs per sq. inch.
My experiments have included putting water in the fuel mixture, injecting
steam into the air/fuel mixture, and injecting water into the air/fuel
mixture.
If the water is mixed thoroughly with the fuel the engine continues to run. If
the fuel and water separates before being cracked there is hesitation.
I use water in the air/fuel stream to control the rpm's of the engine.
When the engine runs on vapors it loves to run wide open. When water is
injected into the air/vaporized fuel stream it lowers the rpm's.
However, when steam is injected into the air/vaporized fuel stream the rpm's
remain constant.
The device is actually a cracking device and any liquid fuel can be used that
doesn't leave a heavy tar residue. The device is not designed to accept
gases (No Hydrogen) only liquids.
Fuels
The device is being tested with gasoline. Diesel may present a
problem due to the residue that might build up in the heating chamber and the
air/fuel mixture requirements of a diesel engine.
About Gerald Rowley
I am a racer's mechanic with over 15 years experience in and off race
track. My experience runs the gamut from 5 hp engines to over 300 hp
engines. I have rebuilt many engines from the block up, some after every
race.
My interest came from go-karts from an early age. I raced every day
making the engines more and more powerful. I learned the intricacies of
fuel types, air/fuel mixtures, compressions, ram air, jetting, bore/stroke,
timing, balancing, etc. What intrigued me the most was the fuel types,
timing, and the air/fuel mixtures. My goal was top performance from
any engine I was working on. The goal was a power range through
high rpm's. This goal was achieved by tinkering with the intake of the
engine. What goes in comes out! I experimented with high octane
fuels and balanced air/fuel mixtures based on existing air temperature and
humidity. So I went to the next step using vaporized gasoline for higher
engine performance.
VAPSTER is actually a device that completes a chemical reaction.
Gasoline is vaporized and is now a higher lean fluid. For an engine to
run on a high lean fluid the air mixture has to be lean also. So,
VAPSTER leans the air mixture by closing the intake 1/2 to 2/3 over the
conventional intake. In the device the fuel/air mixture is constant thus
producing the maximum burn at a constant rpm.
Independent Testing
I have been in contact with the University of Miami to perform a
demonstration and for them to document the results of the control and the
patented device. So far a date has not been established. I have
demonstrated the device to friends.
Willing to Demonstrate
I would like to show more people that it actually does work. The device works
well and I am willing to demonstrate the device to any third
party to document the fuel used by the control and the prototype.
Video Available
A video is not edited or narrated. It shows the complete run of VAPSTER
for 1/2 hour from the start of the test run to the finish. It shows
the change over from liquid gasoline to the vapor stage and the increase in
rpm's as it changes to the vapor state.
