The Ultrasonic Transducer Fuel Vaporizer

Back to Home

The Ultrasonic Fuel Vaporizer is based on the same concepts as our standard model Fuel Vaporizer. The standard model Fuel Vaporizer comes in two versions, but the method of vaporization, and how it aids the combustion process, is the same. We are offering only 1 kind of ultrasonic transducer vaporizer; it uses a float level switch, and 3 way valve, like our Wiseman version of vaporizer, and so will work on any vehicle regardless of what kind of pressure fuel system it has.

Our standard model Fuel Vaporizer uses air which has been percolated through fuel, whether it is petrol(gasoline)or diesel, to produce the fuel vapor. But our transducer based version allows much more fuel to be used in the engine in vapor form. Because the fuel is converted into a very fine mist before going into the combustion chamber by the ultrasonic transducer, the mixture is much richer than would otherwise be possible. Also, because the vaporizer is no longer reliant on the volume of air going into the vaporizer to produce the vapor, it produces a much flatter power curve in the engine, and is more effective at high speeds. So the fuel savings at motorway/interstate speeds is higher.

Also, the acceleration speeds with this vaporizer are also faster than with our standard vaporizer, because more vapor is being produced at higher speeds, despite the lack of intake manifold pressure. We haven't finished 0-60 times yet on all the variations in installation that are possible with this model, but here is the first result. The difference is definitely noticeable at the high end - here we have an approximate 12% improvement in acceleration times. With an installation with 2 vaporizers, one a standard Wiseman for the low speed/idle vaporization and a transducer version for the high speeds going through the air cleaner, the 0-60 time with a 1.8 litre Volkswagen Passat, is less than 9 seconds, about 8.8. The results given in our original table on the standard vaporizer page and with the new timings are:

    Normal  with 1    with 2    with 1 std. &  with 1
            std. vap. std. vap. 1 Ultra. vap.  Ultra. vap.
Secs: 13.8    10.5      10           8.8          8.8

As we can see above, the timings are identical for 1 Ultrasonic vaporizer using both the transducer and air percolation for producing vapor and using 2 vaporizers, one a standard model and the other an Ultrasonic. This says that 1 Ultrasonic produces the same amount of vapor as 2 vaporizers!

The other installation variation to do 0-60 tests are with the Ultrasonic vaporizer on its own: one attached only to the air cleaner as per the most simple installation.

The overall effect on MPG savings over our standard model vaporizer is this: roughly another 20%+ efficiency increase. On our normal car, which we use for testing, the standard Wiseman version of vaporizer increased the MPG from around 35 MPG to about 45 MPG. With the transducer upgrade, it now gets 48-52 MPG. We aren't finished yet with the testing to come up with the optimal test figures, but have decided to release the model now because of the definite increases it is already providing.

There are other benefits. The Ultrasonic Vaporizer can be installed in 3 ways, which allows for easier installation over the standard model The impact on MPG for each installation type depends on your driving, whether it is more in town or more on the motorway/highway. Basically, because the vaporizer is no longer dependent on manifold pressure, the vapor output can be put directly into the air cleaner. It doesn't have to go into the intake manifold, either through the pcv valve or the brake servo hose or through direct entry. This does affect the overall operation of the vaporizer, and the power curve. It can still be installed through the intake manifold, in which case this model will operate both as the standard model and as the new one, both kinds of vaporization going on, percolation and ultrasonic vibration. This will produce a richer mixture at low speeds than if the vapor is just sent through the air cleaner. But the installation through the air cleaner will produce more vapor at higher speeds than can occur with the other installation.

Particularly noticeable is the effect of this model when used with our Ultrasonic Water Vaporizer. We have noted elsewhere that using a number of fuel-savers doesn't increase fuel efficiency to the same extent as they would individually. That is, a number of devices together aren't the sum of their parts, but less so. This is because the effects of a cleaner combustion chamber, for instance, will occur with one device, but not anymore with several; a cleaner combustion chamber doesn't become twice as clean with another device added. But the effect of the transducer based water vaporizer when used with the fuel vaporizer is still to increase efficiency another 20%; in the example above we are talking over 60 MPG (again, we haven't finished testing to give you more precise figures). This must be because the transducer based version of the our water vaporizer is using different means to improving MPG, and we believe its because the water, in a very fine particulate state as it is produced by the transducer, is being used in combustion.

Some time ago, we began selling this unit, but discovered that the transducers we were using were not lasting as long as they had been advertised for: 200 hours rather than 5,000. We have withdrawn the sale of these units for the time being, allowing us some time to test new versions of the transducers and also using completely different designs to get around the problem. The existing orders for the units are on hold; we will re-release the units for sale once we are satisfied the new versions or designs work as they should. If you are interested in the ultrasonic fuel vaporizer, once we re-release it, please email us at:

We will also answer any questions you may have on ultrasonic fuel vaporizers as the research and testing continues.
