Scientific fact:

Hydrogen generators use electricity from the battery of a vehicle to split water (H2O) into Hydrogen and Oxygen.

Hydrogen is produced only when the engine is running and is immediately injected into the engine where it blends with the existing fuel.

The resulting mixture burns more efficiently, significantly reducing fuel consumption and the amount of pollutants released in the air: NOx, CO, CO2 and HC

The effect of hydrogen is predictable and consistent in all non-computerized engines whether carbureted gasoline or mechanical diesels.


Unlike carbureted engines, fuel injected vehicles are equipped with multiple sensors. The ECU monitors all the sensors and it is programmed to expect a certain “normal” behavior.

Hydrogen alters the combustion properties of the existing fuel. When the sensors detect this unexpected condition, the ECU responds by adding more fuel and negating the improvement in fuel economy.

If this problem is not addressed, there will be more power and torque, but no fuel savings.


To accommodate the altered combustion created by hydrogen and satisfy the ECU’s expectations, it is necessary to:

  • balance the sensors of the fuelling system using AutoTuner or Diesel Tuner sensor controllers

  • or directly control signals of the fuel injector using AutoTuner injector controller

This is the only way to achieve results from hydrogen supplementation in fuel-injected engines

Calculation of maximum Hydrogen output


-How to calculate the amount of Hydrogen (HHO) that a generator can produce?


-Generation of Hydrogen is based on electrolysis, which is governed by the laws of physics. This process was studied almost 200 years ago by Michael Faraday, who subsequently published “Faraday’s Laws of Electrolysis”.

The laws state that an electrolysis cell, operating at a certain current (amps) will produce a known amount of HHO.

The two main considerations are the number of electrode plates and the actual ‘active’ surface area. The active area is the surface area of the plates minus the area of the gaskets.

For example, if a generator has 20 cm plates and 13 mm wide gaskets:

The plate area is 20 cm X 20 cm = 400 square cm
The active area is 17.4 cm X 17.4 cm = 303 square cm

The 303 square cm number must be used for calculations.

Michael Faraday also demonstrated that electrolysis cells can support up to 0.084 amps per square cm without overheating. This is the standard used to design a HHO generator.
Therefore, the 303 square cm generator can support up to 25.4 amps of current.

The number of plates is also very important. Too few and the generator will have poor HHO production and overheat. Too many plates and the generator may not work at all.

For 12 volt vehicles, the ideal number of plates is seven, which creates six electrolysis cells within the generator.

As a mathematical simplification of Faraday’s laws, a 7 plate generator will produce 64 ml/minute of HHO per 1 amp of current

So, the generator in our example will have a maximum output of 1.6 LPM (64 ml x 25.4 amps).

Product Overview
Pure Nature Corporation fuel systems are compatible with all types of engines and can be transferred from one
vehicle to another.
The right combination of hydrogen generator and electronic controller is necessary to achieve
maximum fuel economy.
Auto Tuner is a powerful automated fuel reduction system for all gasoline engines. It combines the
maximum savings with ease of use.
Auto Tuner fully controls the injection system and can be used without hydrogen.
Fuel economy:
Auto tuner only: 18-35%
Auto Tuner plus hydrogen: 50-60%
Diesel Tuner is designed specifically for diesel engines to adjust the use of hydrogen.
Fuel economy:
Diesel Tuner plus hydrogen: 40-50%
Besides the increase of fuel economy, the addition of hydrogen provides a significant reduction in
emissions of CO (Carbon monoxide), CO 2 (Carbon dioxide), NO x (Nitrogen oxide) and HC.
(Hydrocarbon). It causes growing concern in urban areas.


The combustion of hydrogen with gasoline or diesel fuel in internal combustion engines has the potential to produce lower emissions and higher thermal efficiency for several reasons.

First, excess oxygen in the charge further oxidizes unburden hydrocarbons and carbon monoxide.

Second, excess oxygen lowers the peak combustion temperatures, which inhibits the formation of oxides of nitrogen.

Third, the lower combustion temperatures increase the mixture specific heat ratio by decreasing the net dissociation losses.

Fourth, as the specific heat ratio increases, the cycle thermal efficiency also increases, which gives the potential for better fuel economy.”

To summarize:

The more efficient HHO engine has more fuel energy converted into useful mechanical energy and less into wasted thermal energy.

This is apparent to the user in increased fuel economy, lower combustion temperatures and approximately 100 C lower exhaust temperature.

The HHO assisted combustion ignites faster and more completely. The same amount of fuel explodes more thoroughly creating more power. This power is transferred into mechanical energy and not heat.

Further, the generated force acts when it is supposed to – at the beginning of the combustion stroke of the engine. Not later when the piston is already half way down the stroke or even worse, while returning on the exhaust stroke.

Residual combustion on the exhaust stroke impeded engine rotation (lowering economy) and increases exhaust temperature and shortens the life of the exhaust valves.
