So, I did what research i could on my own. What I found was lots of specifics on combustion properties of different alkyl alcohols and water ratios.

I also found fuzzy evidence of power as well as fuel economy increases.

From my own experimentation, I KNOW.

My 22re remanned engine is getting 10% better fuel economy and a modest difference in: Engine idle (smoother), Engine pickup ( Low RPMs all gears), and engine temperature.


What I would LIKE TO KNOW, is the long term consequences, if any do exist, from wet injecting Alcohol/H20 vaporized through the intake manifold.

I would assume corrosion as a possibility, but with my engine being new, i doubt that will bring any problems in the near 100K mile future.

 

its the same as driving with a sorkeled air filter in the rain!!!!!! it cleans out the engine i know then i rebiult mine!!

 

I'm sure I'm not the only one who'd like a little bit more info as to what your setup is...details, man, details!

 

well basically, i ran a line from the intake manifold to a sealed container. this container is half filled with 50 50 isopropyl alcohol. vapors are generated via a bubbling apparatus that supplies warm under hood air into the sealed container, allowing the air to bubble up through the liquid. google the novak device for specefics. in principle my setup is the same with only slight modifications.

 

I've run several tanks of E85, probably more gallons of alochol than you'll touch in multiple years with that setup.

It burns cleaner, but with as little as you're putting in, I doubt you'll see any long term impacts or differences.

Typical concerns when running pressure injected alcohol are concerns with old hose compatibility, isses with seals, and corrosion on aluminum parts...

 

exactly what i was worried about. Seeing that I have heard so little about alcohol injection, i just wanted to pop the wuestion on here and see if my assumptions were correct. Thanks for the info, and you drive a 22re? And it's tolerated several e85 tanks. That's encouraging. Personally, seals and hoses are easy to fix. Pulling off the head again, would force me to stick a giant label across the windshield of my truck that would read "head case". lol

 

Yup, E85 won't hurt the engine as such.
You should change your fuel filter after running a couple of tanks of E85, as it'll strip crap that's in the fuel tank loose.
Later model vehicles shouldn't have any problems with fuel lines, etc.
You won't get more mileage with E85, you'll get less.
You also won't get more power with E85, you'll get less (assuming no engine mods).

I have a cross between a 22RE and a 22RTE.
Note, it wouldn't do well on E85 without the ability to control the fuel injection. I wouldn't recommended it on a stock ECU vehicle.

 

It'll work just fine on a stock ECU engine.
Will it be the most optimal setup, no, but it'll run and run just fine.

well it's good to hear that these motors can take it. And I wouldn't even think about putting e85 in anyway. After my alcohol mod, I am getting 22 in the city on 31x10.5s ! Not to mention it's got a wee bit more pickup.

 

ive heard a couple of people doing this with windshield washer fluid supposed to burn the alcohol out of it

 

no such thing as a sealed container that vents- it's contradiction of terms at best, and an oxymoron at least.
By definition of a sealed container, you cannot 'bubble anything "INTO" it if it's sealed. IT IS SEALED! -nothing can get in nor out of it.

You want to do something similar? Fine- put 1 gallon of 100% ethanol, 1 gallon of 100% methanol and one gallon of 100% acetone into your fuel tank then fill it up the rest of the way with gasoline and I'll bet you'll save about 3 gallons of gas per tank every time you do it.

 

ive seen this done before u take a container put a breather on one end with it submerged in the liquid and the vacuum source that goes to your intake above the liquid which creates a bubbling effect

 

Sweet! I use negative-pressure injection whenever I go to MacDonals!!!

 

I use a methanol/water injection (50/50) in my setup, to cool the intake temps. Aquamist 2D http://www.urdusa.com/index.php?cPath=17_88

 

i think what he is mentioning here is a generally refereed to as plain water injection, because the main purpose of it is the water's effects and not the alcohol's effects.
Here is the original link he may be referencing:

Here is a standard performance version of a similar thing:

I am going to do it on a tercel i just bought for $400, should clean out the engine, the carb, give me better power, heat absorption, and fuel economy. The only thing i am worried about is putting tooo much water in the egine somehow, or slowly rusting the inside of the engine. I heard if you mix 10% oil in with the 50/50 water alcohol that this will be prevented. Anyone know anymore about this stufff????? Its been pretty hard to find more stuff about entire do-it-yourself low cost methods. I am deffy not buying any $300-1000 system.

Revival of an old thread....horray!

 

What engine do you have? If it's a standard 22re, what mods did you do to allow it to run e85? Did you have to adjust the timing?
