Hydrogen Enhanced Combustion

This is a promising concept for Ultra-lean combustion using hydrogen in small amounts to enhance combustion.

Ultra lean burn combustion is viewed by many as a necessary next significant step in the evolution of the gasoline engine. However, emission constraints require that these engines operate under stoichiometric conditions to avoid costly emissions control solutions. The addition of small amounts of hydrogen to the cylinder charge can allow these types of engines to operate much leaner than they otherwise could, eliminating the need to treat NOx emissions altogether. While this is not a new idea, it is hydrogen that is bringing this concept much closer to reality.

I want you to understand the concept here. To improve mileage beyond the normal combustion conditions mandated by the government for emissions control, an “Ultra-lean-burn combustion” is considered necessary.  The purpose of our electronic control circuit is to lean out the air/fuel mixture from 14.7:1 to a mixture that is lean enough to prevent unacceptable amounts of NOx emissions (typically above 18:1) and 20:1 in some conditions.

For our homemade hydrogen boosters or hydrogen generator cells to accomplish this we have to install electronic fuel injection enhancers along with our hydrogen generator cells. We also need to manipulate the maf or map sensors to control the amount of fuel injected. If we can take this to 18:1 or leaner and we produce enough hydrogen to compensate for the leaner burn then we will gain fuel mileage. Typically in the 10 – 20% range.

There are those nay-sayers out there that spout off about this concept. They would like to make us believe that the garbage coming out of their mouths is gospel and we can’t get something for nothing. They will tell you about the Myth-Busters show to dis-prove the hydrogen theory on making an engine run on hydrogen. Just look at what those idiots used for a test vehicle. We are not interested in making an engine run totally on hydrogen at this time with our homemade boosters. All we are looking for in an increase in miles per gallon. While it does take energy from the alternator in the form of electricity to produce our hydrogen, the better cells produce enough hydrogen gas to compensate for this energy we are using.

I will tell you that I have a unit installed, and working, that I built and it has increased the fuel, miles per gallon by 10. I am going to install another one on my 1995 Ford Taurus along with the enhancement devices. You must install the EFIE and MAF or MAP devices in order to control the ECM/PCM and lean out your fuel ratio. The Homemade hydrogen cells are not going to increase the mpg alone because the computer will only compensate for the extra oxygen it will see in the exhaust from the O2 sensors and bring the A/F ratio back to 14.7:1. Then you will most certainly see your fuel mpg to drop.

On this site there are plans and schematics for hydrogen cells and EFIE, MAF or MAP schematics with instructions on how to install and adjust them. Use them at your own risk and read everything before you attempt to install and run a hydrogen cell on your car. They do work if installed and adjusted correctly.

Just don’t get discouraged with no gain in miles per gallon on your first try. I didn’t get a gain. In fact I lost 3 MPG and also got a check engine light. I had set my efie to high and the computer finally dis-regarded it. So I did some checks and reset everything and started out with one thing at a time starting with the O2 sensor, then the maf sensor and finally the fuel cell amp draw to get the best hydrogen production.

Do not start adjusting everything at one time.
Do a step by step adjustment on one thing at a time and keep track of what you have done in a log.
If you get an increase it would be nice if you could leave a comment on how you accomplished it.
Happy Tuning!
