Water-Alcohol Vapor Infusion System ( EWAI )

I would not try anything like that on my car unless a whole bunch of you guys did it first.
Something tells me that's not going happen on this one.
you're probably better off with the warm-up electrical hack a bunch have done to cut warm up time.

 

That's the biggest concern, definitely.

 

Yes, that mod definitely seems the best way to gain more mpg, especially for frequent short trip driving distances.

 

Would somebody kindly point me in that direction? I'm finding that my commutes are too short to give me the the sort of efficiency I'm seeing with my longer trips.

 

Sure, here you go:

Really low cost mod too.

 

I did the same type of thing on my dodge neon. The way I understand it is the water vapor or mist dosent matter enters the engine the engine heat causes the water to turn to steam and that process removes a lot of the engine heat that is good for the engine. The problem I found is that this fools the O2 sensors into thiking the fuel mixture is too lean and it adjust. so I just got a smoother running car with a tiny bit more power and the same or less mpg. I would like to see what mpg is over say 6 months before I would think it is likely to work. My mpg can vary a lot on my prius if I drive for max mpg I can get over 70 for the tank. If I drive regular I get a little over 60, If I drive like a teenage boy with his dads gas card I get 55 mpg.

you will not cause an engine problem unless you pour lots of water in. mist no problem. in fact engines have more power in cool humid conditions for this very reason.

 

where can I find out about this warm up cycle mod. I have a prius c and my trip to work is under 3 miles and it ruins my mpg. I think it runs to keep the catalec converter hot or something like that.

Once again you got me, I had not done this since 1981, that was my 1980 Datsun 310, I forget all about this but you pulled me back, I would like to try again in my 2010 Prius too, please send me detail how you do it but PICS is best. Good luck

These things are a joke. I put zero stock in this jury rig of a set up. And... one data point from one person is not going to convince me nor should it convince anyone else.

If it makes you feel better, go ahead and do it but to claim it improves gas mileage by giving us one example of a route that you drove, without accounting for wind conditions, traffic differences, did you catch the stoplight green the second time etc, is ludicrous.

 

“Tested by driving 60 miles round trip with valve cut off; got 50.5 MPG. Next day I drive same route at the same speed with valve open; got 56 MPG, better overall performance ...... this just makes the fuel burn better ...... This installation does not bypass any EPA emissions devices, it's legal and so far it's working!!”



I didn’t read in the OP where a "claim" was made only that his "findings" after the first test were shared and his interpolation of the finding were that it makes the fuel burn hotter, not more efficiently. Maybe everyone who is so quick to jump on the OP for posting his project should read it again or better yet shut the hell up unless unless you have something useful to add other than crap. I’ve seen this lot lately where someone comes up with an idea and 8 out of 10 replies are negative or made to simply make the OP look stupid or the person replying is trying to showcase their superior intellect. Then again maybe I’m giving these nay-sayers too much credit and they are just commenting to try and run the number of comments they have up.

 

Don't tell me to shut the hell up loser.

 

Great diplomacy.
The OP's "findings" will stand on their own merit or not, and if they "look stupid" (your words....) why is it the fault of the critic?

If you're just itching for an excuse to take the bullet out of your shirt pocket there Barney, then there's a blue hyper-linked "Report" button beneath each post. Rather than telling people to shut up you might try reporting offensive posts to the MODERATORS.
Who knows? You might actually improve this forum instead of looking like an underemployed rural law enforcement officer.
The way I see it?
The OP has every right to post his (or her) DIY projects, and I will defend this right against bullies....like you, who would suggest that they shaddup.
But if you come at me with a claim...finding....observation...study...review....that "suggests" that you can increase the efficiency of a G3 by over 10-percent with 50 bucks worth of Ace hardware materials and a few chemicals?
I'm going to throw the BRAVO-SIERRA flag....AS SOON as I read the post.
I'm sorry... but I just give the people who designed and built the car a little more credit than to think that they would walk away from a plus ten percent delta in fuel efficiency by adding fifty bucks worth of crap to the car.
They could make even more money by having a tank inside the engine compartment that you could put the "Prius Juice" into...sold by the dealership.
If this really worked and a 50-MPG car could be legged up to 55-mpg?.........
Why wouldn't the other OEM's who are struggling to meet future CAFE standards be on this?

Please continue to post as loudly and as often as you wish.

 

Stryker 308 never told the OP to shaddup. He was in fact defending the OP from all the negative naysayers posting in this thread.

Could he have been more "diplomatic"? Sure, but so could a lot of other posters.

 

This is the same reason diesel users who have to refill a reservoir with a urea solution that is way overpriced to meet EPA emissions standards, hate doing so. It is considered inconvenient at best, a ripoff for sure, or whatever.

As mentioned earlier in this thread, most owners/drivers wouldn't want the inconvenience of buying, storing, and having to mix and refill a reservoir in their engine compartment, even if it did give them better mpg.

 

From a fairness standpoint, I think that we all need to accept that if we allow anybody a public podium to make a claim, no matter how fantastical or unlikely some (or many) of us deem it to be... we need to allow others the right to question it.

A practical wrinkle that needs to be applied is the firmness of the claim. If somebody makes a half-assed claim with soft theories, justifications, and/or precedent... then yeah, nobody is required to put forth a fully-researched thesis to criticize it. Conversely, a serious claim with similarly serious attempts at justification and experimentation shouldn't be allowed to be put-down with glib dismissals.

But really, nobody needs an Internet hard-guy telling people what they can or can't do. It's humorous for its complete lack of power to effect anything, and is just an invitation for everyone to take the conversation off-track.

 

Concur....
BUT!
I've seen people drive WAAAAAY out of their way to put E0 in their cars....because they "find" that it makes their car more efficient. I see people hacking into their car's wiring to try to defeat the ICE warm-up.....trying to save gas. I see hypermilers blocking their grills.....over inflating their tires.....tailgating trucks.....all in the pursuit of the allmighty MPG.
Do you mean to tell me that they wouldn't fill a reservoir with what amounts to modified window washing fluid every few tanks to be able to claim a REAL WORLD 10-percent uptick in mileage?

I get your point.
I just disagree.
Whether or not you're into the CAFE thing......it's the law of the land.

Time will tell!

 

Yes, that's exactly what I'm saying. Probably less than a fraction of a fraction of 1% would go through all that trouble (hypermiling, grill blocking, sensor spoofing, etc.) to eke out more mpg. Most drivers wouldn't want to be bothered with refilling a tank, even if it gave them more mpg.

 

problem is your 1980 datsun would not change how the fuel mix and timing based on O2 sensor and other parameters so if you add water vapor you can improve mpg. but with these new cars they compensate for many things and it becomes complicated. it confuses the O2 sensor in my 95 neon and then the car increases the fuel mix causing no improvement in mpg. so to do this kind of thing right the engine control programs need to take into account the change in how the engine works with extra water vapor in it.
