How to Make Cars Run on Hydrogen
Brown's Gas, or HHO, is a gas made up of hydrogen and oxygen inside an electrolysis device that is connected to the car's electrical and fuel system. The added combustibles will reduce the amount of gasoline required to run the engine, however, the major obstacle for the modern car is the computer, which will enrich the mixture to compensate for too much oxygen. The average backyard mechanic can install an HHO device in about an hour.

The HHO (hydrogen-hydrogen-oxygen) electrolysis canister is a non-conductive jar filled with baking soda and water, with an immersed wrapping of wire that produces a rapid flow of gas from the water when charged. These gases collect in the top of the canister, where a tube will route them to the air intake hose of the vehicle via a "bubbler." Mounting this equipment depends on the model of vehicle, and building the actual HHO canister is beyond the scope of this procedure. Typically, the HHO jar is mounted near the air box, in a vertical position. It can be held in place with simple zip ties or have a custom built wooden crate if there is room. The amount of HHO produced is also dependent on the number or size of the canisters, and larger engines require more canisters to see improved economy. The bubbler is a simple jar or tank that allows the HHO to come in through the bottom and percolate to the top. This is usually called a "cleaner," and it can be a reused automotive reservoir tank instead of a professional unit.

Route the hoses from the HHO canister to the bubbler unit and the lines from the bubble unit to the engine air intake hose (before the MAF sensor, if applicable). Usually cutting a small hole or digging the hose out with a screwdriver will allow enough room to push a line in firmly. Direct the end of the line with the air flow, so that it is angled "into the wind."

Run wire from the HHO canister to a switched (or ignition-activated) lead on the positive terminal bolt on the battery. HHO canisters will usually have wing nuts or similar terminals that can be turned clockwise over the wire for a solid connection. The ground lead from the canister can go directly to a good ground on the vehicle, or the battery ground. Turn all connections clockwise to secure them.

Splice a wire from the O2 sensor to a variable resistor, then back to the original wire lead. This is the most important part of the conversion and works better on older vehicles. The computer is being "tricked" into thinking there is more fuel than is actually added, but the O2 sensor sees all of the extra unspent fuel, and will richen the fuel mixture. This uses more fuel and must be fooled with a resistor. Since the average backyard mechanic will not typically know the correct voltage or conversion methods for "tricking" the computer, a variable resistor will allow for fine tuning. The O2 wire can be cut, have it's insulation stripped and then be attached to the wires carrying the voltage to the resistor and back. Wrap all connections with a liberal amount of electrical tape.

Add baking soda and distilled water (2 tbsp. for every quart) to the HHO canister, then close it. Add distilled water to the bubble reservoir. Start the vehicle, switch on the HHO, and watch for bubbles to form in the canister and bubbles coming through the reservoir. Adjust the variable resistor until the economy improves.

Tips & Warnings
The less "computerized" the vehicle is, the better the HHO will work. Older cars and trucks without O2 sensors and computers will only require minor carburetor adjustments to work with HHO.
Some models will activate the "Service Engine Soon" light, and store trouble codes if the HHO system is not compatible with the computer system and sensors.
