If you are thinking about building hydrogen oxygen gas generators, there are some things you should know. Unless you are extremely adventurous and have way too much time in your hands, I suggest one of the many products available that show you exactly how to make a pem electrolyzer. Which product you choose is completely up to you, but it will save you a lot of time and energy.
Any basic kit will pretty much call for the same core parts, the electrolyzer, the intake hose, the battery cable, and often times a switch. The electrolyzer is the “fuel cell” which holds the water. Also part of the electrolyzer is a metal plate or spiral (I highly recommend the spiral design) which is submerged into the water and hooked to the power source. This is what causes the actual electrolysis that results in the hydrogen oxygen gas we are looking for.
Atop the electrolyzer fuel cell, you will have a tube which follows directly to your vehicle’s air intake. As the electrolysis process occurs, the gas rises to the top of the reservoir and is sucked into the air intake via the tube. This is where the hydrogen oxygen gas actually enters into the engine and then mixes with the gasoline in the combustion chamber.
Keep in mind there are different ways to activate the hydrogen oxygen gas generators, you can either hook it up to a simple on/off switch, connect it to your vehicles ignition swtich so it is always on when the vehicle is running, or if you’re really clever you can find a way to have it switch on automatically under a certain load or at a certain RPM level. Because the hydrogen oxygen gas is helpful all the way through the RPM range, I suggest having the unit run anytime the engine is running. You will save more fuel overall and you’ll never have to think about turning it on or off. The switch is helpful for testing purposes and I have temporarily set up many units like this for my own research.
The concept is extremely simple but finding the materials and knowing exactly what to use and what not to use can be a little daunting if you’re on your own. As I said before, this project is much more enjoyable and can reduce the build into a science rather than a tinkering project if you purchase one of the commercial guides available.
