I get asked this question a lot. And yet, this is the most important point to understand if you want to make your car more fuel efficient using this technology. The physics and chemistry of this subject can be very complicated. But fortunately the basic concepts are very few and extremely simple.

 

Misconception

First, let me clear up a misconception. Many people think that we are generating HHO so we can burn it, and that burning this HHO adds so much power, that we get better fuel mileage. To take this a step further, there are 3 energy conversions at work here:

• Mechanical to electrical (the alternator makes electrical energy)
• Electrical to chemical (the cell makes HHO from electrical energy)
• Chemical to mechanical (the HHO burns in the engine to make mechanical energy)

The problem is that there are 3 energy conversions occurring here, and each one loses some energy. It is a basic fundamental of physics that in any conversion of energy from one form to another, there is going to be some loss. There is no such thing as 100% efficiency. In some of these conversions there is quite a bit of loss. So if this is all there was to the picture, then the system would actually lose mileage when it was used. I've even seen this mistaken idea expressed in magazines and on television news coverage of the technology.

What Really Is Going On

But this is not how HHO is able to improve fuel economy. In actual fact HHO, when added to the air/fuel mixture going into the engine, causes that petroleum fuel to burn more rapidly. Scientists say that it considerably increases the flame speed of the petroleum mixture. And it is this fact that sums up the primary way that HHO improves fuel mileage.

When the flame speed of the fuel mixture is increased, more of the fuel is burned during the power stroke of the piston. Less fuel is being burned after the power stroke, and during the exhaust stroke, which actually works against the turning of the engine. And less unburned fuel is being expelled from the engine as waste and pollutants. A relatively small amount of HHO will have a dramatic impact on the amount of power a given amount of gasoline will produce. It will also drop dramatically the amount of harmful emissions the engine produces.

A Problem, And Its Solution

Back in the good old days, before there were computers in cars, experimenters were able to add HHO to their engines and get remarkable mileage gains and dramatic decreases in emissions. No other handling was needed to get excellent results. Similarly, diesel engines, even today get excellent results with HHO and need no other handling.

However, with the advent of the computer, fuel injection, oxygen sensors, and other sensors used to control the air/fuel ratio, a problem is introduced into this simple technology. The problem starts like this. When hydrogen is introduced, and the engine is turning more times with less gas, one of the results is that there is more oxygen coming through the exhaust. This is reported to the computer by the oxygen sensor(s) that are installed in the exhaust pipe(s). The computer reads this additional oxygen as a "lean" air/fuel mix. It then promptly adds more gas, until it "sees" the same exhaust conditions it was programmed to expect. However, it is now incorrectly adding gas when it shouldn't.

People with modern, fuel-injected cars, who put in HHO, often report that their vehicle runs smoother, and has a dramatic increase in horsepower. But they also often report no increase in fuel mileage. This is because the computer, that was designed for inefficient combustion, is adding much more gas than is actually needed. What is needed to get all the gains available to this technology is to compensate for this additional oxygen in the exhaust.

A device was created that does just that. It's called an EFIE, which is short for Electronic Fuel Injection Enhancer. Basically this device compensates for the additional oxygen appearing in the exhaust, and allows the computer to do it's job correctly when an HHO system is installed.

Summary

There is a remarkable simplicity to this technology. If you add HHO to your engine, you will get an increase in combustion efficiency. That is just science, and it works as certainly as turning on a light switch. But to get your gains, you have to compensate for the additional oxygen that will now appear in the exhaust. And that is done by modifying the sensor information going to the computer. If you can do these 2 things, you will get a dramatic increase in fuel mileage and a corresponding decrease in fuel emissions.

We expect our customers to get a minimum of 25% increase in MPG, and 30-35% is our expected average. Some people have gotten 50% or more mileage increases. By proper application of this simple technology, you can get these increases for your vehicle too.

HHO 'Oxyhydrogen' will combust when brought to its auto ignition temperature. For a concentrated mixture at atmospheric pressure, auto ignition occurs at about 570 °C (1065 °F). The minimum energy required to ignite such a mixture with a spark is about 0.02 millijoules. When ignited, the gas mixture converts to water vapor and releases a massive amount of cool clean renewable energy, which sustains the reaction: 241.8 kJ of energy (LHV) for every mole of H2 burned. The amount of heat energy released is independent of the mode of combustion, but the temperature of the flame varies. The maximum temperature of about 5000 °F is achieved with a pure mixture when burned at a torch tip. When mixed with air as is the case in an internal combustion engine, the water vapor formed almost instantaneously cools the combustion chamber and cancels out the initial higher temp, but not before increasing the efficiency of the fossil fuel burn. Oxyhydrogen improves emissions and the overall fuel economy of internal combustion engines when combined with air/fuel ratio and/or timing modifications; these effects will be achieved in addition to engine performance.
