"Next Generation Hydrogen Generator"
Herold designed his unit to be compact, measuring only 5 in. wide by 7 1/2 in. long and 2 1/2 in. thick. All tubing and wiring needed is included in each kit. On larger engines you can hook two or more units together.
Herold says the best results with his kits have been on large diesel engines, such as large trucks and motor homes. Farmers are also using them on combines, tractors, irrigation engines, generators, grain dryers, and more.
One problem with most newer cars and pickups is that they have EPA-mandated software programs that dump excess fuel into the exhaust. A thermocoupler at the catalytic converter is used to make sure exhaust temperature gets to 600? and stays there. The way they keep the heat up is by dumping extra fuel. However, when you burn hydrogen, you're igniting waste fuel so the temperature at the catalytic converter drops. This causes the system to dump even more fuel. The way around this problem is to buy a replacement computer chip that adjusts engine burn. They sell for about $69 from a company called Engine Performance (www.engineperformancechip.com).
Herold's website offers pros and cons of four different electrolytes that are added to the distilled water used in the unit - sodium citrate, baking soda, sodium hydroxide and salt. He prefers sodium citrate for its safety, though more of it is required. He also recommends against salt due to its corrosive nature.
"Mix the electrolyte in 1.4 liters of water and fill the tank," he says. "You can start out at five amps if the unit is installed inside the engine compartment and seven amps if it's in front of the radiator. You can be at 13.5 amps in two hours with the temperature in the tank at 185 degrees and maximum hydrogen production."
Herold suggests placement ahead of the radiator for air stream cooling.
"The limiting factor in hydrogen generation is temperature of the electrolyte fluid," he says. "Water boils at 212 degrees so I try to keep my units operating at 185 degrees."
Herold has sold hundreds of systems, which are priced at $125. He also offers an EFIE switch for adjusting the mixture of fuel and air for $15. He also has a website that sells individual components for do it yourselfers, as well as the entire system as a turnkey installation. The site also offers information on making your own, installing and using a hydrogen generator.
