VAPSTER Fuel Vaporizing System
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.
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.
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.
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.
A recent 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.
