Complete HHO Systems
"I'll keep this short and sweet, my generator arrived today and I am absolutely floored with the professional build quality or your products, as well as the level of detail in your controls and online documentation. You're setting the bar for this industry."
D.R. Canada

"Got one from ya a few years back for my 70 chevelle 454 works great! ya probably won't believe me but the thing doubled my mileage had to check it a few times thought I was seeing things, The mileage went from 8.5 to 17 mpg for mod 454 I thought that was pretty good"

"2 dry cells, reservoir, 1 quad digital EFIE, 1 reg digital EFIE, 2 MAP enhancers (dual style). I have them almost 2 years and the products are working fine. Good quality products at a reasonable price and technical help. Low maintenance, good quality. Good installation instructions and troubleshooting info. Longevity and low maintenance, and consistent performance. The MAP enhancer is especially good compared to the one I made because it has a wider adjustment potential. The generators don't discolor the water like the wet cells did. I also like the dry cells because it circulates the water and doesn't heat up. Thanks for the tech support."

"31mpg! CITY! 100% increase! 2000 Toyota 4 Runner, 4 cyl. 2.7litres. I'm quite amazed. I did a long road trip, and quite skeptical, had to pull over every 40 miles or so to test results by refilling at the next gas station. I got 30mpg's highway, and when I dialed my EFIE, 31.5mpgs IN CITY. Awesome stuff guys. I'm getting 100% increase in mpg."

"I'm seeing about 25% increase in fuel economy so I know the system is working. My vehicle is a 2002 Dodge Ram 1500 with a 5.9L gas engine."

"I used the HHO system very effectively for about 2 years on my 85 Mercedes 500SL. I enjoyed this experiment and consistently got 25% more mileage when the system was in use. It really helped when you have an engine that only gets 18 mpg it was a great experience for about 4 years. Keep up the innovative work. I think you are part of a grass roots effort that is pushing the big auto makers to finally start taking mileage and the environment seriously."

"I have one of the systems currently running on my Dodge truck (440 cid), I am getting better than 20%, although I do a lot of in town driving and it messes with the fuel efficiency. On the open road I get much better. Running less than 20 amps most of the time."

EFIE's and Electronics

EFIEs and Electronics
"I have been using your digital and analog EFIE's for more than 3 years, and yes, they work well. Because you are very serious about your work and product, I believe they are the best on the market! Your EFIE's are very well build, easy to install, nice addons such as probe holes. Gains vary between vehicles but 15 – 30 % average. These digital EFIE's are hard needed when you install a watergas system in a fuel-injected petrol vehicle. They are well thought-out, well designed and well build and made to last a long time. I have not seen better quality EFIE's on the market! I'm sure that the other products Fuelsaver-MPG sell are of same the quality."
F.G. Netherlands

"I use many of your EFIEs, and a couple of MAP/MAF devices about 4 years. They are working without a problem. I get about 40%+ fuel savings with HHO. Quick good service - get what I order. Operational always, with good installation instructions. Usually, with older cars, they are not really needed. But, since the inclusion of fuel computers and lambdas on vehicles, the need for oxygen sensor control is very necessary, requiring EFIE’s and MAP/MAF devices to regulate the proper fuel/air (HHO) mixtures. FuelSaver-MPG products have never let me down and the price is right."
D.G. Moscow

"I am using a digital and analog EFIE on a 2002 Subaru. I have been using them for about two years. I get about 25-30% gain. I found your company on line. It appears you folks do a good job. Qualities: Follow thru, quick turn around, quality product, good value. Review: I began experimenting with HHO in 2008. I have always believed that we spend way too much on fuel and find enjoyment in cutting the costs down thru other alternative methods... namely Hydrogen. Nay sayers think it BS. I know there are MPG gains to be had."

"My old truck passed the Texas exhaust inspection after failing the day before without it. I replaced the o2 sensor and added one of your EFIE units. I have an old 1995 Chevy 3/4 ton four wheel drive pickup that I love."

     "My mileage went from 24 to 30 mpg, and I think there's more to go from here!"
     "Finally, HHO Products and SUPPORT that make this work for everyone."
     "I'm glad I can finally show my friends this HHO stuff works!"

The Basic Principles of HHO

Firethorn Project Running Hydrogen Hybrid Electric Vehicle

To make sure you have a good understanding of how and why these systems work, let's take a look at some basic chemistry. We just need to talk about molecules and atoms. Water is a molecule, and a molecule is made up of smaller parts known as atoms. That's the end of the first lesson!

The water molecule is named H2O because it contains two Hydrogen atoms (H2) and one Oxygen molecule. In a combined form they are the abundant resource known as water. Through the simple process of running electric current through the water, the atoms 'split' back into their original elemental forms.

This process is known as electrolysis. Electrical current runs through the water and all the Hydrogen atoms run toward the negatively charged electrode, and all the oxygen atoms move toward the positive electrode.

Water Molecule

Next lesson is to understand the chemical structure of gasoline. Gasoline is made up of 'hydrocarbon chains'. The chains are made up of hydrogen and carbon

'Heavier' chains like C14H30 are used when refining diesel fuel, and even heavier oil blends can really load up on the carbon atom with C20 ratings and higher! The problem with pollution is all the unburned carbon. There is a lot more exciting information beyond this, but for our current HHO application, we only need to clarify the basic principles.

Below is a diagram of a C7H16 chain typically used for automotive blends of gasoline.
Gasoline Hydro-Carbon Chain

Any HHO generator simply adds 'free' hydrogen and oxygen in a gaseous state to the combustion process. The mixture of this burns so hot, and so fast, it helps to COMPLETE the combustion process of the original gasoline.

It burns MORE of the carbon atoms to create lower emissions (fewer hydrocarbon and carbon monoxide particles). It reduces excess heat (a cooler running engine) and it offers more power to the driver (from a more complete combustion of the gasoline.)

From a good understanding of this, we work to develop fuel cells and safety products that push this technology forward. Now is a GREAT time for you to enter this emerging water fuel industry, especially with the current focus on developing alternative fuel sources.

How Does This Technology Work?

HHO causes the diesel (or any other type of fuel) to burn faster. That's really all it does. But this has the effect of causing the fuel to burn more completely during the power stroke of the engine. Therefore, less fuel is still burning during the exhaust stroke where it will actually tend to work against the engine's revolutions. The result is that less fuel is required for the same amount of torque and engine revolutions or be wasted. The immediate primary results are reduced fuel consumption and emissions. HHO isn’t an alternative fuel, but something which increases the efficiency of the fuel you are already using.

Increased Power

Hydrogen powered engines experience significant gains in horsepower. This is caused by the fact that more fuel is burning during the power stroke, giving more power for the same amount of fuel. This results in being able to pull loads in lower gears than before, which saves on fuel consumption.

Improved Emissions

Hydrogen assisted engines always report dramatic decreases in emissions. Some owners have used HHO systems on trucks which then passed emissions testing even after previously failing the same test. This can extend the useful life of older trucks. We have seen reports of hydrocarbon emissions dropping by 85% after just a few minutes of running on a hydrogen system. Emissions results improve for all pollutant gasses currently tested for.

Increased Engine Life

Engine life is also improved. First, because the fuel is burning more thoroughly, there are less unburned contaminants to foul up the engine and contaminate the oil. Secondly, because most of the fuel is actually burning during the power stroke of the engine, you're not wasting as much fuel heating up the engine without a return in horsepower. Engines tend to run 10-20 degrees cooler when on HHO systems.
