Hydrogen generators and HHO tuning

hydrogen hho generators tuning

Set up and operation

Is Hydrogen safe?

The use of HHO is not more dangerous than the use of gasoline. Follow common sense and the basic safety instructions as outlined in our manual. Green Source generators use hydrogen on demand, it gets burned as soon as it is generated. No gas is ever stored.


Will this equipment work on my vehicle?

Our systems are designed to work for any vehicle. You will have to make sure that:

  • You have chosen the correct combination of the generator and a possible electronic controller
  • The generator is installed without any air leaks
  • All the wires are connected correctly

Does HHO work on diesel engines?

It does, and often much better! Diesel vehicles usually enjoy the greatest increase in fuel economy due to the fact that they are equipped with fewer sensors and there is much less computer resistance to deal with.


Will it improve my fuel economy?

There are numerous scientific proofs of the effectiveness of this technology. Third party researchers report reduced emissions, 10 to 60% increase in fuel economy and improved horsepower. Our principal test car Honda Accord realized 53% mileage improvement.

Individual results will depend on the quality of installation, amount of HHO produced and whether you chose to treat and fine tune your vehicle sensors with Green Source signal manipulation devices.


How much HHO is need?

Generally, 0.25 to 0.5 Litres/minute PER litre of engine size is considered to be enough. As an example, if you have a 3 litre engine, then 1 litre/minute is approximately what you will need.

Hydrogen systems are susceptible to the laws of diminishing returns. Adding HHO to the fuel will improve engine’s efficiency, but only to a certain point. Many professional laboratory tests have demonstrated reduce in engine efficiency and performance when experimented with injecting more than 1 litre per minute.

As a matter of fact, we were able to DECREASE the efficiency of an engine by 26% when we intentionally flooded it with too much hydrogen.


Are installation instructions included?

All our equipment comes with very detailed instructions that are part of the purchase. As soon as you place your order, you will receive a downloadable link for latest version of the manual. Our manuals provide basic, easy to understand installation and maintenance instructions as well as more detailed technical information for those who seek greater understanding.


Can I do the installation myself or will I need to hire a mechanic?

Generators are very easy to install. If you have any experience with basic hand tools and follow our detailed instructions you will most certainly be able to do the installation yourself.


Can hydrogen supplementation damage the engine of my vehicle?

It is not possible. In fact, hydrogen helps to protect the engine by lowering combustion temperatures and providing cleaner oil that results from less amount of carbon deposited in the engine.

What is the recommended place to mount the generator?

The generator should be installed away from engine heat to ensure the coolest operation possible. We recommend positioning the generator near the front of the engine compartment where it will receive the maximum cooling and air flow. The most popular location is between the radiator and the front grill.

Maintenance

How often will I have to add water to the system?

Every car is different. Usually, about 500 ml of distilled water is required per 1000 km of driving.


Electrolytes

In order to make water more conductive and produce any practical amount of HHO, the use of electrolytes will be is required. Although, there are several types of electrolyte that could be used in electrolysis, we suggest Potassium Hydroxide (KOH) or Sodium Hydroxide (NaOH).

Sodium Hydroxide (NaOH), also called lye, is an efficient, highly conductive electrolyte. It is available as a 50% saturated solution, flakes, pellets and granules. NaOH is very soluble in water with release of heat. You can find Sodium Hydroxide in grocery stores labelled “Red Devil” drain cleaner. It is also available in agriculture stores or at industrial chemical suppliers and hardware stores.

Potassium Hydroxide (KOH) is considered to be the most efficient of the common electrolytes. KOH falls into the category of dangerous goods and is subject to shipping regulations in many countries. Potassium Hydroxide is available on eBay and online chemical distribution centers.

Here is a list of online resources:

KOH is the best, most efficient choice of electrolyte in HHO electrolysis. It can be purchased here.

This is a great source for chemicals used in hydrogen systems.

Winter operation

Hydrogen generation is based on the use of water, which if freezes may cause damage to your HHO system. Here are two solutions:

1. Mix 50% / 50% water and isopropyl alcohol. It will guarantee a -30C (-25F) freezing point.

2. Adding NaOH or KOH to 1L of water will help to reach the following freezing points:

1 TBSP KOH = 30g = -2.8C

2 TBSP KOH = 60g = -5.6C

3 TBSP KOH = 90g = -8.3C

4 TBSP KOH = 120g = -11.1C

5 TBSP KOH = 150g = -13.9C

6 TBSP KOH = 180g = -16.7C

7 TBSP KOH = 210g = -19.4C

8 TBSP KOH = 240g = -22.4C

Electronics

Handling electronics

Most modern fuel injected cars have O2 sensors. When HHO supplementation device is used, gasoline burns more completely and efficiently. However, if the air fuel ratio is not reduced, there will be a noticeable increase in power but NOT in fuel economy. An Electronic Fuel Injection Enhancer (EFIE) is required to deal with O2 sensors to achieve maximum economy gains on these vehicles.

To get the most out of your HHO system:

1. Limit and control HHO flow rate with a Constant Current Pulse Width Modulator

2. Use Green Source ProTuner or EFIE to increase air-fuel ratio and improve the engine economy.

Electronic Fuel Injection Enhancer (EFIE)

EFIEs are electronic devices used to make adjustments to the signals of O2 sensors. It “tricks” the computer of a car to boost efficiency to its maximum potential.

Green Source is the only company to offer Universal EFIEs. Our Electronic Fuel Injection Enhancers are designed to control both narrow and wide band sensor types. This saves you the trouble of determining your sensor type before purchasing and allows seamless transfer to any other vehicle.

Why is there a need to trick the computer?

When hydrogen is introduced to the engine the vehicle maintains the same performance, but operates with leaner (much less gasoline) air to fuel ratio. One of the jobs of the vehicle computer is to monitor the oxygen sensor in the exhaust and to decide how much fuel to send at any given moment.

The purpose of EFIE is to electronically adjust signal of the O2 sensor and prevent the computer from interfering with the operation of HHO system.

Why is digital betterl?

Most EFIEs you see on the market today are analog, what it means is that they simply add a certain amount of voltage to the signal of O2 sensors.  The instant problem is that the car gets “Out of Bounds” with the altered signal and triggers the “Service Engine” light.  The ECU will consider the O2 sensor malfunctioning and will ignore this “illegal” sensor voltage. Moreover, the computer will switch into safe engine mode and the vehicle will consume even more fuel.

Green Source digital EFIEs are true digital devices designed to tell the computer to add more or less fuel by sending “authorized” compatible signals. When digital EFIEs are used, the “Service Engine” light will not trigger.

Do diesel engines benefit from an EFIE?

Most diesels vehicles as well as simple carbureted engines are not equipped with oxygen sensors, thus there is no need for an EFIE.

What is a Pulse Width Modulator circuit and do I need one?

A PWM circuit quickly switches a hydrogen generator on and off. A user sets the percentage of on time to control the HHO flow rate. Hydrogen systems are based on electrolysis and produce substantial heat. If the heat does not dissipate or does not get regilated, it will build up and will boil the water in the generator. PWMs allow the use of such efficient electrolytes as KOH and NaOH by controlling the current and the temperature of operation.

PWMs are extremely important if:

1. KOH or NaOH are the electrolytes of your choice

2. You like a little convenience and would rather not experiment looking for the optimal flow rate.

3. You intend to work the generator near its maximum potential or you live in a warm climate and heat dissipation is a concern.

Why Constant Current PWM?

All engines require a consistent supply of HHO. CCPWM, unlike a regular PWM circuit, makes it impossible for a HHO generator to keep increasing its flow rate when it warms.  Other systems allow the generators to keep getting hotter and as they do, draw more current. This issue, called “Thermal Runaway”, is a condition that inevitably results in boiling the water in the HHO generator.  As an example, even if the generator is set to 10 amps, when it gets hot, it can increase up to 15 amps. This is not what you want as any HHO system requires a constant HHO flow; if not, it will keep blowing fuses.

To prevent this issue Green Source provides only CCPWMs. They maintain original set points under all conditions.

ProTuner - the maximum economy gains possible

Adding an EFIE to a HHO generator improves the economy, but it also creates a conflict amongst the various sensor readings in the vehicle’s computer system. Although this is absolutely normal and acceptable, the fuel economy gains will be limited by the amount of readings conflict that a particular vehicle will be able to tolerate.

The Green Source professional tuners resolve this problem by taking control over engine sensors, minimizing the conflict and maintaining harmony within the system. ProTuner gives its “approval” to the car to use less fuel, thus increasing economy.

If a vehicle is equipped with MAP and/or IAT sensors, ProTuner is the optimal choice you can make. This is also true for many diesel engines that are not equipped with oxygen sensors, but do have MAP and IAT sensors.

ProTuner is an all-inclusive, best value automotive controller available and it also features an integrated CCPWM.

HHO configurations and fuel economy gains

Individual results will depend on the quality of installation, amount of HHO produced and whether you chose to treat and fine tune your vehicle sensors with Green Source signal manipulation devices.

HHO only: 10-25%

HHO plus EFIE or EFIE-CCPWM Combo: 15-35%

HHO plus ProTuner: 30-60%

HHO facts

How Hydrogen supplementation systems work

Hydrogen generators use electricity produced by the battery of a vehicle to split the water molecule (H2O) into oxygen and hydrogen elements. The gas resulting from this process is called HHO.

The generated HHO gas enters the air stream of the vehicle and further to the engine where it mixes with the existing fuel. This new HHO enriched mixture burns faster and more completely.

Hydrogen assists the combustion process; it does not generate fuel from the water.

The science behind HHO supplementation has been well researched, understood and documented. It has been a common knowledge for more than thirty years that the combination of hydrogen and fossil fuel when burned in internal combustion engines, will drastically improve the efficiency of the engine. This concept has been confirmed by a number of reports published by the Society of Automotive Engineers (SAE). This application is effective with any fossil fuel including LPG and diesel.


Dry cells and wet cells

In a dry cell design only a minimum amount of liquid is contained in the generator body. To store the water needed for the system a remote reservoir is required. Compared to wet cells, dry cells are more efficient as only very little electrical current is wasted in the process of electrolysis.

Understanding the importance of the number of plates

Number of electrode plates is one of the most important aspects of a dry cell design, yet it is also the least understood. The efficiency of a cell is proportional to the number of plates, to a maximum of seven. This seven electrode plates configuration means one “positive”, one “negative” and five “neutral” plates, creating six electrolysis reaction chambers. Simply put, each reaction chamber requires 2 Volts, that is why a 12 Volt car is limited to seven plates cell. 13, 18, etc. plate cells are basically several six chamber cells put together to form one unit. Every individual cell still functions at 12 V. It is the large plate surface of five neutral plates that ensures a good, efficient generator. See the example below.

Number of PlatesNeutral Plates per ChamberHHO Output @ 25AmpsCell Rating
751.8 Litres/MinuteExcellent
2531.2 Litres/MinuteFair

 

As you notice from this chart, the seven plate generator creates 50% more HHO than the 25 plate design. Moreover, the cube shape of the 25 plate version will operate hotter and will be prone to poor circulation and overheating.


How many litres of hydrogen can be created from one litre of water?

1 litre of water can produce 1,860 litres of HHO gas.

For each gram of hydrogen burned, 34116 calories are produced.


How much electricity is used to generate HHO?

8 to 15 AMPs will generate enough HHO for a 3L engine vehicle. This amount is similar to how much current is drawn when you turn on the stereo.
