Automotive Hydrogen Generators and Delivery Systems

Automotive Hydrogen Generators and Delivery Systems are also known as Hydrogen Generators, Hydrogen Boosting Technology or Hydrogen Injection but, no matter what you call them the idea behind the technology is to deliver a small amount of Hydrogen Gas into the engine to improve the combustion of your fuel. As a result you can drive further with less fuel and less emissions. But, this technology is not a new idea, in fact the first US patent of this technology was by Charles Frazer in 1918. His HYDRO-OXYGEN GENERATOR claimed to improve efficiency, enhance combustion and eliminated carbon deposits.

Many studies have been conducted around this technology that have proven it’s benefits. In 1970s in an effort to reduce payload capacity NASA studied this technology and found it to increased flame speed and extended lean burn ratios for internal combustion engines (ICE) in other words adding Hydrogen causes the fuel to burn faster and more completely meaning less wasted fuel and oxygen a very import discovery when you have to transport your fuel and oxygen where you are going. See NASA study

Demonstration of this technology

In addition to the NASA Study some more notable research includes:

A1974, the Jet Propulsion Laboratory (JPL), prepared a report for the Society of Automotive Engineers (SAE) entitled “On-Board Hydrogen Generator for a Partial Hydrogen Injection Internal Combustion Engine”.

The California Environmental Engineering (CEE) who tested this technology and found reduction on all exhaust emissions. Their report stated: “CEE feels that the result of this test verified that this technology is a viable source for reducing emissions and fuel consumption.”

News reports have also chronologed how this technology saves fuel.

How does Hydrogen Improve Gas Milage?

We know from numerous studies that adding Hydrogen to an Petroleum Powered Internal Combustion Engine causes the fuel to burn faster and more completely. The power stroke of a typical Internal Combustion Engine is as follows:

In the past improvement in fuel economy improvement was limited to about 5-30% due to defaults set up in vehicles ECU. This is the problem, when hydrogen is introduced it would increases the rpms of the engine and the ECU would reduce the fuel to keep rpms based on throttle body location. The amount of Hydrogen that could be added was limited by the oxygen sensor and engine timing.

As H2 is increased combustion of fuel the O2 sensor gives a lower voltage output. There are 2 ways to increase you MPG due to this set up reduce the amount of Hydrogen being delivered to your vehicle or manipulate the signals to your ECU.

Most system actually deliver too much Hydrogen to the engine upsetting the O2 sensor and causing the engine to work harder because it is combusting too much fuel during it’s compression stroke.

By reducing the amount of Hydrogen gas to the engine usually between .1l-.5l based upon your fuel consumption is enough to improve combustion properties but not upset O2 signal outputs.

The ECU will naturally default to a better map table due to improved combustion effeciency increased RPM giving you better mileage.

O2 Sensor Extenders can then be added to the pre catalytic Oxygen Sensors this will place the sensor higher in the exhaust gas where more Oxygen and Fuel Vapor can be found giving a higher voltage output and reducing the fuel injected into the engine.

The other way is to manipulate signal output from the O2 sensor with an EFIE which adds voltage to the O2 sensor output. Because of the timing issue we spoke about earlier, you can quickly start losing ground trying to do this because as you add more Hydrogen your RPM will start to slow again because you are combusting too much fuel before it reaches TDC creating more work during the compression stroke.

So what is new with this technology today?

Today this technology is being rediscovered due to higher fuel prices and concerns over global warming. People are learning that installing these type system in their current vehicle improves their gas mileage and reduces emission. In fact many people are getting better gas milage by converting their current vehicle into a Hydrogen/Gas or Hydrogen/Diesel Hybrid than they could by buying a new Gas /Electric Hybrid.

Just as automotive technology has changed since 1918 so has Automotive Hydrogen Generators and Delivery Systems. Today there is software on the market that allows you tune your vehicle to optimize your vehicle new Air Fuel Mixture and we call this technology Hydrogen Tuning.

O2 Sensor and ECU

The reason is the O2 sensor give a lower signal is that it is actually measuring the Air Fuel Ratio. The O2 sensor is a catalytic converter and a thermocouple and since there is less O2 and Fuel available to be converted by the sensor into heat there is less voltage output.

This lower voltage output tells us two things 1) The hydrogen is driving lean burn conditions in the engines cylinder and 2) more fuel is being delivered to the engine because the ECU does not know you are adding Hydrogen to the system lowering the voltage output and just think more fuel is needed.

How does Hydrogen Tuning Help?

By adding Hydrogen and adjusting the timing an Internal combustion engine its efficiency can be dramatically improved. A good Hydrogen Tuning Software will allow you to extend the lean burning condition and will also retard the timing as more hydrogen is being added based upon the voltage of the O2 sensor.



Today larger and more consistent MPG gains can be achieved in both Gasoline and Diesel engines by Hydrogen Tuning. Hydrogen Tuning involves updating of a 3-dimensional table of values inside your cars ECU called a map. This map table tells your fuel injectors exactly how much fuel to deliver given current air temperature, density, engine speed, throttle position, and even provides new values for the O2 sensor.

By updating these reference tables in your car ECU so it recognizes lean burn condition when Hydrogen is introduced into the engine and adjust timing and amount of fuel being delivered to the engine you can maximize your engines efficiency.

Types of Hydrogen Tuning Systems

Hydrogen Tuning can be accomplished in two way,s the new map values can be loaded directly onto your car’s ECU using some custom software or they can be placed on a flash drive where your ECU references the table.

To place the new map on your ECU requires computer an install program and OBII connector wire. It is done a location that install HHO Units. Although the installation is simple this is way to maintain control over software licensing.

The other way vendor keep control over their softwares is by using flash drive with map table for a single vehicle. This flash drive connects to your OBII connection and uses this high speed serial input/output to communicate directly with the ECU . This flash drive can be installed in about an hour and can be done by most DIY.

Where Can I Get this Technology?

For an index page of companies pursuing this technology, see: Directory:Hydroxy or HHO Injection Systems

Currently there are a few places that you can get this technology on a flash drive they include:

[Yahoo HHO Store]-HHO Store offers the technology to convert your car or truck into a Hydrogen/Gas or Hydrogen/Diesel Hybrid. We sell one of the best Hydrogen Generator on the market today the H2-Hydro-Gen and some of the harder to find ancillary equipment if you were looking to build your own HHO System.
