Hydrogen Generators for Cars and Trucks

Hydrogen generators for cars and trucks are becoming increasingly popular. And, why not, since these units can increase gas mileage, increase engine performance and decrease emissions all at the same time.

Hydrogen generators for cars and trucks are sometimes called hydrogen boosting technology or hydrogen injection or even hydrogen additive technology.

But, no matter what you can it, they all work in a similar fashion.

The idea behind onboard hydrogen generators for cars and trucks is that they use electricity provided by the car to electrolyze a small amount of water and inject the resulting hydrogen and oxygen gases into the vehicle's intake system. The hydrogen and oxygen displace some of the fossil fuels in the cylinders, help the gasoline or diesel fuel to burn more efficiently, increase power and decrease pollutants coming out the tailpipe.

Disclaimer: One must note that hydrogen generators are controversial right now as critics say they don't work and if they do they don't work as well as some vendors advertise.

Below is a list of some of the more popular hydrogen generator kits and DIY systems that are currently on the market.


Hydrogen DIY Plans

Smack's Booster is a DIY system that shows garage inventors how to build the electrolysis unit step-by-step.
