HH O generator

[PT_Texas]

Update with version 2: I installed a 6 plate system and I'm not seeing the mileage I had with the 5 plate system with 2 neutral plates. The new system produces more gas and I suspect that I've reached the threshold where the O2 sensor has modified the mixture. I have a PWM installed, so I backed off on the amps some to reduce the gas. I'll see how the 2nd half of the tank goes. I haven't added an O2 mod yet.

I did calculations in both for this trip so I averaged about 33 MPG (4.5L) and 27 MPG (3.78L). There was a lot of mountain driving involved it has definitely made my engine run smoother and I don't think I have adjusted the EFIE to its right setting yet. The CEL light came on again on the way down there so I drove the rest of the way with it on. The HHO production is at a good point I think I just need to make some other adjustments. We are using a 2 Cell system of our own design. A fully saturated unit with a reservoir and bubbler. I am using 1/4 stainless steel rod, has proven very effective for us. I am using a 40/60 mix of water and vinegar. It takes the guess and clean work out of using baking soda.

What size gallon are you figuring on? 4.5L Canadian or 3.78L American? My car averages 25-27mpg (4.5L gallon) and on a roadtrip I averaged 36mpg driving 90km/h and 33mpg driving 110-130km/h with a/c on. Best tank was 39.7mpg. That is all with no HHO.

Are you using a jar type system like me or a plate type system? I'm not sure if mine is producing enough HHO.

Hey Blueglitch, have you had any issues with using vinegar? I've heard that it prevents corrosion of the plates, but I've seen some videos that showed a lot of foam when bench testing. How do the plates look? Does the fluid color change? I've read that distilled water and KOH is supposed to be the best solution, but I'm using that and I'm still getting discoloration which means something other than H20 changing to H2 and O2 is happening.

On my first system I had a huge issue with the vinegar foaming but that is because the nuts I was using on my stainless steel rods weren't stainless steel as well and they corroded away in a week. So the downside to using vinegar is that it reacts with any type of soda so anything that you are using inside the solution needs to be T-316L grade. I am still getting discoloration on my new configuration but there is no clouding or clustering just a smooth brown solution. We put our most latest configuration on another PT Cruiser and it only has the clouded yellow mix and has been in for about 3 weeks now. We decided that vinegar would be best because we are taking a consumer approach and KOH will burn the skin if it isn't handled properly.

so if you can keep it real simple is there a way to build this and install it with just simple skills and about what is the projected cost

[PT_Texas]

If you can attach the plates together without them shorting out, then you have the necessary skills. If you build it right the first time, without experimenting with different styles (like I did), you can build a unit for less than $40.00 (don't forget an inline fuse). You can invest in a 30 amp Pulse Width Modulator (PWM) which is a DC motor controller. They are available online (eBay, etc.) for about $25 - 35. This will allow you to control the amps. A cheap amp meter ($17.00 plus shipping) is another worthwhile purchase to see what's happening. Another tricky part will be running the wires safely into the cabin for the amp meter and PWM. Further enhancements include modifications to the MAP sensor and/or O2 sensor. Plans are available for build it yourself type, or you can purchase pre-made. Those will set you back about $75.

Start off with just the electrolyzer and see what happens. You can add the rest later to improve results. Without modifications to the O2 sensor and/or MAP you probably can't get more than about 15% improvement, If you succeed in making a lot of H2 and O2, you may have the sensors tell the computer to go to "limp home" mode (default fuel mixture) which will give you no improvement or even worse mileage. If that happens, back off production (less surface area, or reduce the amps or electrolyte).

Mounting the unit in a PT engine compartment is a creative task. I put mine in the air box under the air filter. I flipped the air filter upside down and trimmed to fit. Not an ideal situation, but good for experimenting. A cold air kit is probably the final solution, but that would have skewed my results.

If you have more questions post them, we're here to help. Wish I had found this before I started, it would have saved me a hours of experimenting.

all right then so tell me where can I buy the complete kit ready to hook up fill up and turn on????

[PT_Texas]

There are several companies selling "ready to install" units, but I haven't seen one that will fit in a Cruiser. Most commercial ones are 4 inch PVC that is about 12 inches tall. It would probably fit behind the grill in front of the radiator. No matter what, you can't set it and forget it, you have to tweak and tune over the weeks as you drive.

[warped]

does anyone have pics and a Grocery list of what i need. Im not stupid (computer tech by trade) and I know some very smart people. I think I can get it done but what do i need. And also how often do you change the mix.

[crusierdad76]

so there is not a lot of activity on this any body have any updates?????
