Aqua-tune

I've personally seen the benefits of hydrogen injection on fuel injected vehicles. I've seen 20% MPG increases and very noticeable power increases via the seat of the pants test. This was on a 1990 Cadillac.
What about this www.aquatune.com?

Hmm. I have never seen that one before. It might be right up there with the tornado or a good way to put seafoam into the engine.

Let us know if ya buy one and install it....

I guess the theory is that the more water vapor in the air mixture, the more powerful the explosion in the cylinders. That, of course is limited to the amount of moisture the air can hold, which is a humidity level of 100% when, technically, it's raining.

This concept was very popular back in the 1970's, around the time of the "gas crisis". Back then, it did not do anything but make sales people rich. Because basic science has not changed since then, my assumption is that it is only good at making a new generation of sales people rich.

This forum is chock full of ideas on how to improve both performance and mileage. Use the search function and then read on. I think you'll be better off listening to these folks.

. This happens because hot carbon and water don’t mix, somewhat like nitro colliding with glycerine and small carbon deposits going by valve seats and helping to break off other deposits...giving a clean sweet machine with a much higher compression ratio and a more complete burning of fuels, making in essence a half steam engine, half gas engine.
Water injection has been used for years to clean carbon deposits. By cleaning the carbon it lowers the high compression ratio caused by the carbon deposits.

Water injection by it self doesn't add power. It cools the intake charge temperature making the air denser and allows you to add more fuel and more timing.

It is the alcohol that is added plus the added timing that increases the power. How are you going to add timing on a computer controlled engine? What does the Alcohol cost? You could also get a kazoo and blow music into the manifold and break up molecules.

A friend of mine has been tinkering with hydrogen injection in his cars for years and this is where I have seen the improvements documented. I mentioned this Aqua-tune to him and he says that the performance numbers touted are not out of the question. He has not seen water separated without an electricity source however.
It is not the water or humidity that increases the power yet it's the actual hydrogen that is separated from the H2O that gets injected into the engine.
Water has been used for years to cool intake charges on turbo engines but the water is never separated in order to use the hydrogen in that application so I don't know if a comparison can made.
This friend of mine ordered a kit yesterday for his 1996 Dodge Ram 360 Magnum in hopes of figuring out if their claims are valid and to see how they break down the water. He was told he would have it early next week. He said he knew I wasn't going to spend the money but he can right it off for his business.
I'll let you guys know what happens but I don't know how long it will take him to see MPG changes because he uses the van to haul heavy loads a long distance only a couple times every 2 weeks.

I doubt that this device can seperate the Hydrogen and Oxygen on a scale such that they can be combusted to produce water again. It probably can say that Hydrogen and Oxygen are seperated because AT LEAST ONE molecule is broken apart due to natural occurance so it would not be called a false claim per se.

Ya just got to love these people. LOL

With current technology, it takes more energy to split the water molocule into hydrogen and oxygen than you get from recombining the hydrogen with oxygen to get water (which is what happens when you get power from hydrogen). If that were not true, we would be powering *everything* with power generated using hydrogen as a fuel source.

Yep, hydrogen is a nice clean fuel source condsidering the byproduct of combustion is water. Whoevers finds a way to economically mass-produce hydrogen will be a zillionaire.

My friend just made his 1st run from St. Paul to Superior WI last week with the Aquatune installed on his Dodge Maxivan with Magnum 360. This is a trip he makes 50 times a year and he keeps very accurate records of his mileage all year. The temp when he left was -10 and in Superior it was colder than that.
This is the coldest it's been here in several years.
On the way up empty he gained 12% MPG and on the way back fully loaded he gained 10%. There is a long steep grade coming south out of Duluth and with the load the tranny will always downshift out of OD before he's 1/3 up the hill. With the Aquatune it downshifted at roughly the 3/4 mark.
Aquatune gaurantees 25% MPG increase but my friend is willing to give it a few more tries because of the uncommonly cold temp during this trip. The kit comes with instructions on how to set it up for more MPG vs. more HP and even has a "racing" setup. He'll play with that and play with the water/isopropyl mixture.

I will post a link in this thread while I still have internet access.

It gives the merits of alcohol and water injection without all that sales mumbo-jumbo...

water has a very high expansion rate. One cubic ft of water expands to 1700 cubic ft of steam/water vapor at 500 degrees, and 2400 cubic ft at 1000 degrees. I'm not exactly sure on these figures, however it's real close to this.



Theory is by intoducing water into the combustion chamber,

1.) it will expand with more volume than air/fuel mixture alone.

2.)cooler incoming air is more dense, and contains more O2 per Cubic ft .

However unless that water injected air is sent by the mass air meter, it will still cailbrate for the volume of air it measured. If you make the air charge denser, you can pack more into the cylinder.

Water also will asorbe alot of heat, heat is expansion! at some point it will use up more heat by adding the water, and reduce the normal thermal expanion.

Last thing I want in my engine is alot of water vapor.

hydrogen injection is different than water injection. i wouldn't want water in there either.

As is alcohol in injection different than water injection. 2000 degree water is just water vapor. What ever benefits it has are not coming from the energy contained in the water. The water simply cannot be a fuel soruce under these conditions. It certainly has the ability to absorb heat, but how does this help a properly functioning engine?

So how do you keep the water from freezing at -10? Is it in the passenger compartment? I have seen frozen water mistakenly used as washer solvent at -10. It wouldn't unfreeze after hours of driving.

Just thinking here but on a van that gets 15 MPG at best a 10% increase is only 1.5 mpg improvement. This would need to be trended over many trips to prove it was not caused by some other external influence (wind force, cold dense air, ect ...)

The hydrogen is separated from the water and then it's injected into the engine. Water is not injected into the engine. Buses in Europe are currently running on hydrogen. The kit costs $375.00. Guys are buying air intakes for $275.00 just to get a better sound. The power difference with the Aquatune seems from the 1st run to be significant. I still don't know if this is worth the cost but the 12% increase in MPG came on a day the was at it's warmest -10 degrees and went to -25 in Superior WI. It will be interesting to see the results closer to the temps documented on runs without the Aquatune.
The mixture used is 25% - 50% isopropyl and doesn't freeze. The jug is kept in the cab. I still can't say I'm sold on the kit but these numbers show that it is doing something. The MPG numbers without the Aquatune have been documented over more than 50 runs on the exact same route with the same load one way. Never has the MPG been as high as with the Aquatune and the temps with Aquatune were the coldest ever during this trip.
