Diesel Power Magazine Disappointment.


After a member here said that Diesel Power Magazine was going to have an article that was going to settle the hydrogen injection system debate I bought a copy. Inside the relevant article was a major disappointment. To sum up the article. These systems consist of electrodes in a jar of water and baking soda. Some people say it works. Some people say it doesn't work.

I know I was setting my hopes too high by expecting something really substantial from a mag that is primarily known for their pictures, however they are also known to do a lot of dyno runs.

I guess all I can do is ask for a follow up article and suggest a test procedure that can settle it once and for all.

list of materials for test.
One diesel vehicle with a mechanical injection pump and high output alternator.

One diesel vehicle with a computer controlled common rail injection system and high output alternator.

Optional third vehicle identical to one of the others.

Note: vehicles should be about the same HP.

2 eddy current dynos

Multiple hydrogen generation cells.

One high current switch.

One high current ammeter.

High current wire.


1. Place two vehicles on dynos.

2. Hook hydrogen generator cell(s) gas outlet to intake of one vehicle and supply the electric power to power the hydrogen generator cell(s) from the other vehicle through the power switch.

3. With the switch open (off) adjust both vehicles output to be roughly the same and hold the power output level on the dyno. For one test the power should be about 25%, one at 50%, one at 75%, and one at full load.

4. While sustaining the power level, Close the switch(turn it on) and measure power increase in vehicle receiving the gas from the hydrogen generator cell(s) and the power drop from the vehicle supplying the electricity. If the current drawn from the supplying vehicle exceeds the current rating of the alternator the test data is invalid because power is also being drawn from energy store in the battery and not provided by the engine. If the current drawn is not more than 80% the alternators rating add another hydrogen cell to the system and repeat steps 3 and 4. Note: the power drop should happen quickly after the switch is closed on the engine supplying the electricity and the power increase should happen with in a few seconds on the engine receiving they hydrogen.

5. After all output levels have been tested exchange connections on vehicles and repeat tests.

Note: since alternators are usually 90 to 95% efficient the power required to generate the hydrogen for the other engine should be statistically the same as if it was generated on the engine ingesting the hydrogen.

The reason for using two different vehicles was to eliminate arguments about the computer changing things (for better or worse)

Comments suggestions?
