HODINFO is a collaborative think tank/ open science initiative. We are an International group comprised of inventors, scientist, mechanics, tinkerers, fabricators, and out of the box thinkers. Our mission is to find innovative solutions to the problems that primarily limit the production and delivery of H2. As the world starts using hydrogen it becomes clear that immense infrastructure initiatives will be required to make it happen. If adequate solutions can be found to support Hydrogen-On-Demand (HOD) systems then the world can remove great and costly limitations on future applications. The future is not just Hydrogen, it's Hydrogen-on-Demand.

still more indicator

Posted on January 18, 2017 at 2:46pm 0 Comments

More work on indicator diagrams:

The first plot below is called an indicator diagram, a plot of pressure vs. volume in the cylinder of a small, 4-stroke gas engine.   It's not much different from an earlier one  except that the plot covers about 2 and 1/2 cycles so the intake / exhaust stroke is visible as well as the compression / power stroke. There is some noise on the pressure signal so it as been oversampled - 9 samples for every data point. Note that the maximum volume…


Electronics assembly

I feel that electronics will be important to future development of HHO technology. Here are some photos showing what its like to work with one very small aspect of electronic systems,  surface mount capacitors.

In order to build prototypes of electronic systems,  the capacity to use surface mount…


more work on test bed

Photos of the latest work on our engine test bed. They are:

Upper left hand.

The test bed will have a software-based controller so we are presently writing the code.  The components of a bench top test are labeled.

Indicator diagram

Posted on March 21, 2016 at 3:30pm 0 Comments

After some tinkering around to get things working right...  we have a preliminary indicator diagram.  Various assumptions were made that might have to be refined.   The exact point on the trigger disk that corresponds to top dead center has to be determined. A mark made with a Sharpie marker on the engine block where the shaft key lines up was made when the cylinder head was removed, but that is not quite good enough.  Will have to use one of those TDC indicators screwed into the…

You might add a coil to the spinning load cell to generate the Pwr to send the data back without depending on batteries, If you can get this data in sync with the crankshaft position then it can also be plotted along with combustion pressure. you should be able to use the coil charge waveform as position with each torque reading.

Hey Charles I'm right with you on using a Pic & pressure sensor, I do have a question about spark timing & the 60 tooth sensor, how are they related ? or are there two systems, I ask because quadrature encoders of higher counts can do both, on many systems we use a min 200 count encoder to resolve 800 CPR. Will you include temp in the data?

Hello Mr. Ware

Thank you for posting your findings. It was concise and sensible and begins to fill a void of useful data.

I did some simple dyno tests using a chassis dyno and a Chevy 4.3 that showed a very nice gain in the

more useful lower RPMs. Wish that data was as comprehensive as yours but it does reveal what we all know is real. HHO is very useful.

Here is a paper I did:



I have yet to receive a single comment about it.  The equation section I would like to simplify and make it a little more persuasive. I am really interseted in the idea of optimizing poerfoirmance of HHO systems, but it is hard to do that systematiclly without a quantitative understanding of how HHO affects the thermodynaomics of the heat cycle. I am actually working on a prototype at this time that would address this issue.
