The International Open Source Hydrogen On Demand Builders Network.
HODINFO is a collaborative think tank. 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 wakes up to the idea of using hydrogen it also becomes clear that immense infrastructure initiatives will be required to make it happen. If adequate solutions can be found to support HOD systems then the world can remove great and costly limitations on future applications. It is important to realize that the future is not just Hydrogen, it's Hydrogen-on-Demand.
Ran the engine on the test bed to check the inputs.
The scope can store the data as a csv file which can be imported into a spreadsheet and plotted. Here is the pressure within the cylinder:
On the shaft is a trigger disk with 60 tooth positions, but 2 teeth are missing to provide a gap used for reference. So there are 58 cycles of the signal between the two gaps. The two plots are on different time scales. The top plot represents 10 rotations and the bottom plot represents about 1.5 rotations of the engine.
One use for this program is doing good quality evaluations of HHO injection. By running the engine at a controlled speed and load, measurement of fuel consumption under highly controlled conditions may be possible. Hopefully, the measurement will be maybe 99% as good as what could be done in an engine lab, yet, as you can see, it is a rather simple inexpensive setup. The most expensive part was the fiber-optic sensor which cost about $1,100. Still, that is a lot cheaper than an eddy current load absorber and associated equipment.
Takes a long time to put everything together, so the progress is very slow.
