Constructing the hydrogen gas saver is only the first step in the right direction, but without a proper tuning to the car the it is impossible to really increase the internal combustion engine efficiency. Tuning the car’s injection system or the carburetor is our next mission.
In order to really start saving fuel and reduce emissions we need to make the engine to work in lean regime (less fuel per cycle). This mode is only possible thanks to the hydrogen booster we described earlier.
if we just increase the amount of air in the mixture the engine will run hotter,
but if we replace some of the air with Hydrogen/Oxygen mixture from the booster the
combustion running temperature will actually go down while the engine converting
more chemical energy into motion instead of heat, in other words increased efficiency.
Important Note: Do not try to lean engine’s work without fuel saving device such
as hydrogen gas saver, this could hurt the engine due to over-
The obstacle: Oxygen sensor -
When a Hydrogen booster is in use, part of the air in the engine is replaced by Hydrogen-
In order to save fuel a change in the oxygen sensor signal is needed.

In my experience, the most effective two ways for making the engine work lean are those:
The most accurate way, that works in all situations is the
Electronic Fuel Injection Enhancer. This mean an electric circuit
adjusting the signal from the oxygen sensor to change the
fuel / air ration in the burning process. More in the HHO EFIE page
There is a possibility to reduce the fuel injected per cycle using a small
metal part called “Spacer”. The spacer connects between the oxygen
sensor and the exhaust pipe and removes the sensor from a direct
contact with the exhaust emissions. In result, the oxygen sensor “feels”
less oxygen and less fuel injected during the burning. This method isn’t
“scientific” and isn’t adjustable but due to good result in certain cars and
very low price it is worth a try. Read more in the “Spacer” page
Generally, it is easier to tune a carburetor to work lean. As easy as turning couple of bolts. But since I never tried to pull this out, I cannot give you complete picture of the process.
From talks with people I got the impression that a car with a carburetor can get very high MPG, maybe ever higher than injection cars. I am eager to try out this issue, and soon I getting a test car with carburetor for experiments. Stay tuned for updates.
