How to make the intake air more humid to save gas.
<p>Back in the 70's gas crunch water injection kits were sold to increase mpg. The theory is humid air expands more when heated than dry air so less fuel is used to make the same power. The theory is sound but the kits made back then didnt work well. </p><p>Ever notice your car runs better in cool foggy weather?<br /></p><p>I was thinking about this when I saw a room humidifier at my sisters house. It uses some sort of pezo electric dodad to turn water into a cool vapor. I am not mechaniclly handy but thought could one of those things be put in a cars intake with a tube running to a bottle of water?</p><p>I hope someone out there handy with cars can give this a try. what do ya think?<br /></p>

Stuff For Sale
<p>Hopefully some of the experts can chime in here. I've heard arguements for WARM air helping gas mileage, as well as COLD air. Now we can throw HUMID air into the mix. Let me poke around and see what I can find out about it. </p><p> I'm certain it wouldn't be difficult at all to manufacture a HAI (Humid Air Intake), but you'd have to somehow account for the air filter. Standard air filters would disolve, and race filters (like K&N filters) would probably clog up pretty fast with the extra moisture.</p><p>Perhaps add the water AFTER the air filter?<br /> </p>

<p>Food for thought.</p><p>The Air Force used to have planes that had water injection to boost power. the jet engines in the first B52's needed water injection just to get off the ground. Later models had better engines and didnt need it. In the begining KC135's used water injection too. They have all been modified with bigger engines.<br /></p><p>Some prop planes during WWII used water injection as well. No jets back then. </p><p>Up intill 5 or 10 years ago bases had to have demineralized water on hand for these beasts. </p>

<p>I was thinking about this last night and I had a few questions. First of all, weren't all cars carburated when the last gas crisis occured? Would the Humid Air Intake work better on carburated engines than fuel injection?</p><p>Secondly, isn't water in the gas typically something that is considered a bad thing? I mean, you get water in your gas tank and your car dies. How would putting water in the air intake be any different? See if you can find any information on the net about this, as I'd love to read more about it. </p>

EPA Test Graph?
There are a bunch of things out on the market right now that do just this. You hook them up to your intake and they shoot some liquid in their for a better leaner mix. Those things don't work. They've been reviewed by a lot of consumer groups and they say they are all bunk. However, water may be different because this other injection things might just use some crap to get you to buy it. Mehbe you could retrofit one of those crappy kits to inject wudder instead and see what happens.

Putting moisture in the intake air is different than putting water in the gas.
Humid air when heated expands more than dry air. When your spark plug fires and starts the combustion of the fuel air mixture it is the expansion of the gases that forces the piston down making hp and torque. more power per unit of fuel means you can let off the gas pedel a bit. |

This sounds like a pretty sound theory, do you have any idea how to rig this up xor how to store the water and that type of thing?

Or would could just put a hole in the air intake hose and feed some moisture in that way. It could siphon off of a spare wiper fluid container modified for this very reason. |
an increase of 20mpg cost me...
Hell, I could just rewire my rear windshield wiper to shoot some junk in there, but the motor is awfully powerful for the situation, and it'd have to work all the time, so that idea actually sucks. But the storage idea is good. Could just hang a thing in there like when you wanna put a dangerous fish in a tank with other fish and not have it kill them all.

My cousin is weird.
yes water injection kits are very popular with the racing community also they use ethenaol injetion.
The main function of these systems is to suppress detonation caused by high temperature and pressure developed within the combustion chamber when the effective compression ratio has been taken beyond the auto-ignition point by either a turbo or a supercharger. Water, with its high latent heat content, is extremely effective for controlling not only the onset of detonation but also the production of oxides of nitrogen in the modern leanburn engines. |
thanks svoboy for the info
thanks svoboy for the info on this site..
i got 48mpg out of my civic this week.........mostly pushing it stead of driving lol |

Has anyone ever used liquid electric tape?
no i just keep tire's inflated and i have a 92 civic vx with vtec-e for getting up hills. 87 hp is alittle rough, but it's a 2100lbs car so that makes a diffrent. i also have a front lip that help deflects wind.
i need to reduce my wieght 245- 200 and drop the car 100lbs and i should get another 1mpg. |

car also has 170k on it and i'm getting a major tune up done on it next week.

Roflmao
Let us know what happens after the tune up, should be interesting to hear!

Only engine i have seen this kit on it forced in duction and one has a 150 shot of no^2 the water injection would shoot the same time the no^2 did.

Can you identify the wires in my o2 sensor?
That sounds pretty scary for me, as an mpg guy. Mehbe I'll ask my cousin, he boosts to 20 or 25 I think, but he doesn't use nos...

No more diesels in California
I'll serve this file for a little while so everyone can download it. This is a step by step for creating one of these things. The author does not tell you how much of a gain you get in terms of mpg though.

More proof of a conspiracy
Yep, so pretty good. Can you emaill the guy who did it for some numbers on mpg and stuff? Also, fill up every five days, gosh, I wonder how many miles that is...

I think there used to be ads for kits in the back of Popular Science. likely in the late 70's too.

Second Official GS Meet
Ok you guys. Can we take the info from the past and modernize it. Find a newer better way to get water vapor into the engine. maybe something like in my first post. Something like the room humidifiers use. I'm thinking a fog like vapor of water will work better than tiny droplets drom a spray nozzle.

perhaps Diemaster can help with the electronics here. A humidifier isn't too complex. I'm sure if we took one apart we could EASILY get it to fit inside the air intake tube. Perhaps it can even be wired to the a switched power source that comes on when car starts. |

Is it okay to buy a high mileage honda??
I'm sure the thing is electric. My guess is it uses DC current so should be easy to power in a car. Using the throttle sensor is a great idea. If we could varry the vapor output to match the throttle it would be perfect.

Hey
I don't see what that isn't possible! We need to do some diagnosis I spose and rip apart a humidifier.

with water/alc injection kits, how do you go about tuning for better mileage? less fuel? timing retarded?

Do-It-Yourself Water Injection
Do-It-Yourself Water Injection
https://journeytoforever.org/biofuel_library/ethanol_motherearth/me3.html These guys were selling bags of water for $30 that you were supposed to place in air filter box. You could make your own cheaper. https://www.cs.cmu.edu/~dst/ATG/#force https://www.cs.cmu.edu/~dst/ATG/jcwhitney.txt Maybe if you set water with gelatin it would stay in place. |
I'm thinking about doing
I'm thinking about doing water injection by drilling a hole on the throttle body and letting the vacuum do the work.
