HHO system in Opel Astra 1.6i
« on: September 18, 2010, 11:34:56 am »
Here some pics from my crappy experimental hho design in my Opel Astra 1.6i 1992. You probably expect a full design under the hood, but that is not handy for the learning process and to make modifications. I've got nice results and when the long term testings are finished, I'm gonna build it all under the hood. I can simply take this block out and work on it on the bench.

All problems are solved during the building of all this. I had some leaking of the tubes, some heating on the wires. I used thicker wires and used glue for the leaking problems.

The white stroke is the hose length and direction in the air intake

These dry cells are not so efficient as shown in many others HHO forums. While I was building these cells I noticed a 21 plate design should be much more efficient with this combination +nnnn-nnnn+nnnn-nnnn+ So I do not recommend to replicate my cells.

I make my plates out of old stainless steel diner plates. I buy this plates for 30 to 80 euro cents a piece at recycling shops over here. I don't know what the quality is but I have a small magnet with me to check if it is stainless steel.

As you can see I have a lot of work to do for my next design, for a heating unit for one of the rooms in my house.

My first tests where no good at all. All cars with O2-sensors will "say" to the computer or regulator, "My fuel mixture is to lean please give some more gasoline". It is the Oxygen in the HHO that causes this reaction. The result is the engine gets more gasoline and thats no saving at all. My car runs without HHO 1liter gasoline for 14.3 kilometers. With this configuration 1 liter gasoline for 10.2 kilometers. An EFI is needed!!  Seems like the most simplest version on the market. I could pay with PayPal and the shipping costs are not that high. No overkill in functionality just what i want.

I installed the EFI in my car like this

(http://www.sumopaint.com/files/images800/hgeiixzifnoiirpe.jpg)

Mileage without hho unit 1 liter 14.3 kilometers
With HHO unit Output EFI 0.28volt 1liter gasoline 17.5 kilometers (47.05MPG)
With HHO unit Output EFI 0.42volt 1liter gasoline 22.1 kilometers (52.27MPG) +35.2%
With HHO unit Output EFI 0.51volt 1liter gasoline 17.5 kilometers (47.05MPG)

Cranking up the voltage output from the EFI will bounce on a limit what I understand out of these numbers. I go back to the 0.42 setting and put a little more to find the max. See what coming out this week when I do my normal 'go to work' trips.

Opel Astra 1.6i
build 1992
HHO 2 dry cells output 1 liter per minute
1 teaspoon Potassium Hydroxide
12 volt system, amperage draw around 20 to 25 amp
1 wire sensor
EFI reading with a standard multimeter between the green and the white wire from the EFI

Update 18 July 2010
I've got some bad results while driving for a few weeks now. I noticed the Potassium Hydroxide causes the mixture to be brown rust water ??? That is not going to happen with Sodium Hydroxide. I have to start again with new measurements and conditions. To be continued  :-\

I don't think you can blame the electrolyte for brown 'rust', it's most likely the water (if not distilled) or the plates (depending on material).

I have used distilled water so I don't understand. Maybe some residues where left in the cell from the citric acid that I used to clean the plates. Anyway I go drive a while with sodium hydroxide and see how it goes.

Hi Knovos,
 
Nice results for 1 litre HHO in your engine.
You also might play with less HHO and Efie adjusting, to see what the impact is.
The reason is that i heard that too much HHO would give worse performance.
Not sure what the limit is on that. If you would build a 2 or 3 litre system, you could play more with that part.
 
Question: Does your car have an airintake sensor?

Ps.
 
I moved your topic to your own project section here.
