HHO cell as fuel saver a fairy tale story? First Impessions in saving and performance with alternative fuels for Diesel
85HHO Cell for 2.5 to 3.8 L Engines
Saving with Dual fuel systems for Diesel,Gasoline or LPG
This is a Report and my first impressions for the efficiency of the dual fuel Systems. That means with one conventional fuel (Gasoline, Diesel or Gas ) and hydrogen in internal combustion engines.
My Observations and actions to improve the systems may help mechanics but also DIY pioneers to achive better results.
After 10 months and after I have installed abt 28 HHO cells kits in stationery engines in heating burners in diferent passenger cars, as well as commercial vehicles and trucks I think that I have the knowledge and the experience to help any one who is interested to work with HHO systems .
I must admit that at the beginning I was sceptical and rather disappointed from the fuel saving results.
Though the performance had increased atbout 20% and in some cases up to 33% and the engines were running smoother (especially diesel engines) the fuel consumption was remaining the same or showing a saving of a tiny 3% !!
My first action was to stabilize the current (Ampere) of the cell at the maximum permissible value.That happened with the help of one PWM regulator and one Ameter.
The "maximum permissible Value" is the value by which the cell will produce maximum quantity HHO without overheating. Lower current is producing less HHO and Higher current will cause the well known "boiling effect" which means overheating of the cell plates and consequently steam bubbles in the supply hose to the engine without (or very litle) HHO production in the cell. Aditionally to this the Cell will be destroyed due to the overheated plates.
After search, personal experimenting and reading several studies I came to the conclusion that for best performance and fuel saving the most suitable mixture and quantity of HHO in l/min. to be added in a Dual fuel System is a ratio 0.7 : 1 or 1:1 of the Volume of the Engine in liters.
That means for an engine of 4,000 cc (4 L) you need 2.8 to 4 L/min HHO.
The next thing I had to do was to install one O2 sensor EXTENSION in order to regulate the air enrichment to the fuel demand.
Farthermore I placed a duble entry of HHO to the air intake and in such a position so that I could increase the entry streaming speed of the gas to the engine. Of course I installed also two nonreturn valves first to protect the circuit from any back fires but also to use the HHO gas only during the gas acceleration cycles.
I would also strongly recomend the installation of a droplets separator on the hose between HHO exit of the tank to the HHO entry at the air suction
Last but not least was to delete the memory of the central ECU of the vehicle so that the ECU could "learn" the new fuel/air operational conditions. In a big number of vehicles you erase the computer memory by disconnecting the Minus pole of the Battery for 4-5 hours or better overnight.
In some cases it is also recomended to install a HHO EFI CHIP Microprocessor configured for the specific vehicle.
Latest news: I have started experimenting with high frequency voltage which is supposed to have a better HHO production with very low current so stay connected
I hope to be able to publish results in the near future

FINAL CONCLUSION
After the proper installation and certain modifications In my car (FORD SCORPIO 2.3L
6 CYL.) during a trip of 2,500 km I had a fuel consumption saving of 23%.
By a VW GOLF 1.4 l gasoline/LPG the saving was 17% by 90% LPG driving.
Other engines including one marine engine had a saving between 16 and 24%
So it is a FACT and not fairy tale that HHO its a fuel saver but DO NOT believe any one who will promiss you more than 25% consuption savings.
Since this hub is for every one to read it is not proper to go in to farther technical or scientific details but for some others interested to install HHO Cells I am willing to assist.

I am glad my Article did help.
Increasing the current by 1-2 Amps if the Cell is not overheating it will not harm the Engine.
If at all possiable, i am starting anew, and putting my rep on the line. I ave a shop in Spring Valley, CA. and starting to install HHO. I do make them, i have them on my race cars. Both have been proven in the HP gain dept. I would like to hear some of your stories, to avoid teh whoes, with someone that has, and knows the market. I want peoples faith renewed in this but do not know how, really. But i belive in this and would love to make it happen all over again, seems like 09 left a bad taste in everyones mouth with this.Very nice write up, thanks for the work.
Thank you
Every one who is planning to install a HHO cell in his car either DIY made or from a manufacturer should not believe in false promisses or miracles.
A good Quality HHO cell with proven efficiency and by proper installation will give a better engine performance and a limited fuel saving gain
Dear Aki,
Thank you for your comments.To avoid the oxygen problem there are in markt some HHO cells which only supply H. Do you have tested them? There also HHO cells with Titanium main plates to avoid sludge.But for me the main problem is the scarcely place the new cars have to install the HHO system.Many people are working in a better H production from Aluminium .What is your opinion about? Thanks
Dear Rafael
Thank you for your message. As you have seen in my article the HHo cells are working perfectly with a satisfactory efficiency but I am still experimenting for improvement. So far a have eliminated the "brown water" sludge by using a different metall composition for the plates (anode-Kathode. Also high Frequency has a very promissing effect. To my opinion the dual fuel system is more accurate since the use of pure H or H2 demands expensive parts and exact configuration like the LPG systems.
I like and appreciate your hub.Great post!

Thanks for the great article. I recently installed a home-made HHO unit in my car, and I have definitely seen results. I did not know about resetting the ECU and I appreciate the information. I use a 1:2 ratio of liters/minute HHO to engine size, but that is mostly due to me being afraid of introducing too much HHO into my engine. Great post.
