Road tests are very time consuming and each test cannot be finished in one trip if the route is very long. And there is a lot of factors involved that could affect your test results: weather, fuel station/pump, driving speed, etc.
While carrying the road test, one question kept coming up: Is there a single test that could demonstrate if and how much a HHO generator can save fuel?
The same answer kept coming in: test the gas emission in the exhaust!
Living in Alberta, where vehicle emission testing is not enforced, I do not even know where I can get this type of test here – if you know, please let me know.
Let’s face it. Since the real reason why supplemental hydrogen can save fuel is based on the fact that hydrogen burns clean and hot, it reduces the amount of unburned fuel in the exhaust. It sort of recycle the unburned fuel for more complete burning. So the real and crucial test if this is indeed the case is to test the gases in the emission. If indeed the amount of unburned fuel is reduced as a result of introducing hydrogen to the engine, then the claim is fully warranted.
In fact, I have watched a YouTube video that shows the emission test before and after HHO injection and that HHO does help reduce unburned fuel in the exhaust, but I could not find the video now.
Update: After searching at YouTube, I did not find the one I watched but found this video. Here it is…
If the generator is equipped with a way to adjust the amperage, then it is even better if the emission test is done at several amperage settings so that we have a curve for the vehicle. This way we know how much HHO can give us the highest fuel saving.
So if your local city has this vehicle air emission testing program, please do some tests of this sort to find out “if” and “how much” your HHO generator can save the fuel this way. For those who can get this done, I appreciate if you could post the results here. Thank you!

Use Guaranteed To Pass first: http://www.autobarn.net/ch05063.html You need one bottle for a 10 gallon tank, two bottles for a 20 gallon tank, etc. Find an exhaust analyzer like this: http://www.globalspec.com/FeaturedProducts/Detail/NovaAnalytical/Portable_Engine_Exhaust_Analyzers_Model_7460_/12244/0. Any tune-up shop should have the needed equipment.
OK, I asked the site owner of VIECOFuel.com and he did make an air emission test with the HHO cell ON and OFF. Here is the result done on his Honda Civic:
Bone stock, no HHO generation, no sensor offsets
—————-
HC PPM : 550
CO % : 3.88
02 % 8.53
CO2 % : 7.19
Alexis Cell ~@15 A straight DC around 2.2 LMP (fully conditioned)
EFIE Offset .25V
MAP Offset .08V
————–
HC PPM : 286
CO % : 0.66
02 % 11.8
CO2 % : 6.83
That is 48% decrease in total hydrocarbons in his car’s exhaust test. Wonderful? Note also that the percentage of CO (carbon monoxide) is reduced by almost 500%.
If you have done a similar test, share with us here.
