How to Fit an HHO Cell

How to fit an HHO cell into a car or truck is quite straightforward. I would definitely recommend a manual, if you do not have one already. They are excellent value for money and will show you how to make as well as fit an HHO cell. Anyway, here are the basics of what to do. (Author: David Payn)

You can find more details about HHO cells and manuals by clicking here.

Take normal flexible plumbing hose and hook up your bubbler from the top of the electrolyzer. It is better for the bubbler to be housed a bit higher in your engine compartment than the HHO cell, but it is not essential. If it is higher, it means that any vapor collected during operation will flow back to the electrolyzer when the unit is not in use; it saves you having to clean it out so often.

Your bubbler can be as far away from where you have fitted the cell as you like. Space is often at a premium under the hood of modern automobiles, so you may be limited as to where you can place the bubbler and HHO cell. Some folk even attach them to the front of their grill. Anyway, measure out the distance between bubbler and cell before cutting to length.

You will then need to measure the distance (with any bends and turns) from your vapor catcher to the hole you have made in your carburetor intake hose. Cut to length.

The final step is to connect your electrical unit, which controls the whole system. They vary in sophistication depending on the manual you are following, but this is basically what you do. Remember, I am only telling you how to fit the HHO cell, not how all the individual components are made.

Connect the positive wire to the top of your HHO cell and the negative wire to the bottom. You need a good gauge wire with a fuse (15 amp is good in most cases) going to the car battery. You will need to connect the wire to the on/off switch on the electronic control unit itself. Then one to the vehicle’s ignition fuse and then back again to the on/off switch.

Finally, you will be left with three or four, depending, negative wires. Connect them all together for convenience and send them to ground.

To fit an HHO cell is pretty quick once you have decided where to position the components. On most cars and trucks I can fit an HHO cell in about 20 minutes. Of course making the HHO kit itself takes a little longer. That said, I get all the parts mailed to me and in a tiny workshop in my kitchen, with minimum tools, it takes about 3 hours to come up with a fully functioning kit. More …
