Since raw gasoline is involved with this project, safe practices are absolutely required....No Smoking....No flames....Use your head !!! This design is based on Patent No. 3,227,427 issued 1/4/1966, now expired. The drawing illustrates a device, according to the inventor, achieves a 50 to 100% improvement in gasoline mileage. The inventor claimed that he achieved 50 miles per gallon with a full size Chevorlet sedan equipped with a 327 cu in V8 motor. He sold the patent to Gulf Oil for $54,000 in 1968. Before going any further, keep in mind while reading this, that only gasoline VAPORS burn in an engine. Anything that has not turned into vapor, gets blown out the exhaust pipe and into the catalytic converter, where it is burned. That's why the catalytic converter get so very hot. There are three ways gasoline is vaporized: Evaporation, heat and vacuum. This device uses engine vacuum to vaporize liquid gasoline that is sprayed, blasted or jetted, against the head of a carriage bolt. The head of the carriage bolt or other such domed or spherical shape, provides a large, extremely thin layer of gasoline for to make it easier for the vacuum to "rip" into vapor. Liquid gasoline that does not turn into vapor, collects in the bottom of the chamber, drains down to a pipe T, connected to the suction side of the fuel pump, and re-circulates over and over, until it is turned into vapor. Make up gasoline, as needed, flows from the fuel tank, normally. A vapor lock will not occur. Vapors are sucked out of the chamber, via the 3/8 vapor line (E), into a vacuum portion of the carburetor (see construction details). Construction Details The device has been built, using a pint salad dressing jar as the container. The inventor indicated that he originally used a large Page 2 Pipe T for his prototype. Until experience is obtained, the glass jar is recommended so that the flow rates of the liquid, levels and vapor can be observed during experimentation. Using a 1/2 inch, glass drill bit, drill a hole in the bottom and sides of the jar. Position the holes directly opposite each other and midway on the jar. Use kerosene as a lubricant for the drill bit, and take your time while drilling. Use a light pressure on the drill, and let the drill bit do the work. Being extremely careful, install 3/8 inch brass compression fittings in the holes drilled in the glass jar. Use large diameter fender washers on both sides of the glass for reinforcement. The washers are glued on the jar, using a silicone glue (Elmer's). The washers will better fit the jar, if the washers are bent slightly to conform to the curvature of the glass jar. The compression fittings are then installed into the washers and jar. Tighten the fittings on the outside of the jar before you install them in the jar. The fitting nut on the inside of the jar must be tighten very carefully or the jar will crack. Use a silicone sealer not affected by gasoline, as a sealer. The jar MUST be air tight. It may be necessary to enlarge the holes in the washers to provide clearance for the compression fitting. To use 1/4" copper tubing in a 3/8" compression fitting, solder a 2 inch piece of 3/8 tubing on the end of the 1/4 copper tubing, that fits into the 3/8" fitting. Install a 3/8" compression fitting in the lid of the jar. If the jar lid is made of thin material, it may be necessary to use fender washers on both sides of the lid as reinforcement. The spherical or domed shaped object (A), is mounted so that the jet of gasoline sprayed out of the nozzle (D), hits the exact center of the dome. A 5/8 " carriage bolt or a stainless steel teaspoon, are ideally shaped. The idea here is, to create as large and thin sheet of gasoline as possible, so the vacuum will rip it apart. However, be careful not to make it so large that raw gas is sucked into the vapor supply line to the carburetor. (A teaspoon is suggested after seeing the large thin sheet of water that was created by holding the spoon beneath a kitchen faucet.) The teaspoon can be mounted by bending the handle, so that the wide part of the handle can be supported by the nozzle compression fitting. Some experimenting may have to be done, to determine the optimum position of the spoon. Drill a hole in the handle of the teaspoon, to mount the spoon on the supply nozzle, compression fitting. The vapor supply line to the engine (E), is a 3/8 or 5/16 line, connected to the carburetor or to a plate beneath the carburetor or in the case of a fuel injected engine, in the main engine air intake. Before a connection is made to any of these points, the following information must be considered: o Ideally, a device such as this, should be usable while idling, slow speed while in traffic and high speed cruising. It should Page 3 also provide enough vapors during acceleration. However, this will be the most difficult to achieve without supplementary help, when using vapor. o When accelerating, engine vacuum is low, and will not be enough to change the liquid gasoline into vapor. Vacuum will be high when idling and decelerating. o A vacuum will always be produced, except while idling, when the vapor supply tube is placed in the fast moving, engine intake air. Vapor will be sucked out of the container exactly the way paint is sucked up, in a siphon spray gun. o The outlet of the 3/8" pipe that brings in the vapors, must be positioned in a fast moving air stream to draw out the vapors. The best spot on a carburetor, is directly in the middle of the ventura. However this is now occupied by the jets. On a fuel injected engine, the vapor line should be placed in the main engine air intake. On both the carbureted and fuel injected engine, the vapor intake tube should be no less than 3/8 inch diameter and the end cut to a 45 degree angle. The best of all areas of performance: start up, idling and cruising, can be obtained by removing the entire jet assembly out of the ventura of the carburetor, and leaving the accelerator pump and jet, and the idling jets. Connect fuel lines to both the container and the existing carburetor, using a compression T fitting. Gasoline will be required by the carburetor only, when idling and accelerating. Seal the holes left by the removal of the jets, with an epoxy sealer, such as JB Weld. Locate and drill a new hole for insertion of the vapor supply tube in the exact middle of the main ventura. Install a 3/8 inch brass compression fitting in the hole drilled into the ventura. This will allow the vapor pipe to be moved in and out, for the optimum position. Position the 45 degree cut tip, exactly in the middle of the ventura. If you decide not to modify the carburetor, and use a plate beneath the carburetor to bring the vapors into the engine, keep in mind that maximum vacuum will occur when idling, and decelerating, while the carburetor butterflys are closed. Vacuum will drop drastically when accelerating, and performance will suffer. On the fuel injected engine, locate a spot in the engine air intake where the air is moving the fastest. The vapor supply tube is installed at that point. On computer controlled, fuel injected engines, when engine vacuum is low, the fuel injector will provide the raw gasoline for acceleration. This is accomplished automatically by the engine computer. When vacuum is low, and insufficient vapor is fed into the engine, the engine Oxygen sensor will sense the lean fuel mixture. The computer turns on the fuel flow to the injectors to overcome the lean fuel mixture. When the engine vacuum is again high, vapors will be produced. When the Oxygen sensor senses the rich mixture as a result of both vapors and the injectors Page 4 providing fuel to the cylinders, the engine computer will reduce the fuel flow to the injectors, until the raw gasoline is turned completely off. o Install a small valve in the 1/4 inch drain line, to make adjustments. o Locate the container as close to the carburetor or vapor input to engine, as possible. Locate the container slightly lower than the vapor entrance point on the carburetor or intake manifold of fuel injected engines, to reduce the chance of liquid gasoline from getting into the engine. Keep the vapor supply line as short as possible. Turn Up Connect the fuel line from the fuel pump, to both the carburetor/fuel injectors and the vaporizer container. Install a valve in the gasoline supply line to the carburetor. Now for the most difficult part: Start the engine. Adjust the vapor supply line in and out of the carburetor or intake manifold, for maximum vapor production. The very volatile gasoline vapors, will resemble light gray smoke. Adjust the drain line, so that gasoline just covers the bottom of the container. A small amount will be needed to make maximum vacuum in the chamber. The weight of the liquid gasoline in the bottom of the vaporizer and the drain line, acts similar to a one way check valve. If gasoline begins to build up in the container, open the valve accordingly. On the carbureted engine, when the engine begins to stumble and produce black smoke indicating it is too rich, slowly shut off the liquid gasoline flow to carburetor. If everything is right, the vapor chamber will be producing enough vapors to keep the engine running. Drive the car and insure that enough vapors are being generated while the engine is running at higher speeds. Decelerate, and insure that raw gasoline is not building up in the container faster, than the drain line can handle. This will require making several adjustments to both the supply nozzle and the drain line, before a balance is achieved. Hopefully, you now understand the basic principle behind this device. Once you have understood the theory and operation of the device, and know what adjustments are made, the glass jar can be replaced by a metal container, which is considerably safer. Additional Information that may be helpful: 1) Some brands of gasoline will vaporize easier than others. 2) Summer gasolines have additives included, to restrict evaporation. Winter gasolines have little if any, additives. Page 5 3) Evaporation may be enhanced and the effective power of the gasoline increased, by installing a charcoal filter on the output of the fuel pump. The charcoal removes most of the additives, paraffins and varnishes, found in the gasoline. 4) Use a paper filter on the output of the charcoal filter to prevent minute particles of carbon from getting into the injector or the carburetor. Only activated charcoal will do. Whole house charcoal water filters, will do the job. Eventually, the charcoal will become saturated with all of the garbage it has removed. Replace when a reduction in performance is noticed or 5000 miles. A great carburetor cleaner or fuel injector cleaner, can be made by adding 1 ounce of Naptha (found at paint stores), to one gallon of gas. Octane can be boosted by adding 1 ounce of Isopropyl alcohol and 1 ounce of Methanol, to a gallon of gasoline. Check drug stores and paint stores. ....Later.... -------------------------------------------------------------------- If you have comments or other information relating to such topics as this paper covers, please upload to KeelyNet or send to the Vangard Sciences address as listed on the first page.
