Simple Water Injection System

[risyia]

Seeking advise from all the sifu out there.

I have just had an idea for a simple water injection system.

My idea basically requires a water nozzle spraying water onto an open pod air filter making it wet.

The suction from the air filter will draw fine water droplet into the combustion chamber and as such create the cooling effect of a water injection system to produce more power.

Would this system work or create problems??

wah... spray water directly to the air filter and let water go into TB... first time hear that... wont damage the engine arr??....
if combustion chamber is wet, it can create good combustion??... engine wont 'kong'??

 

[drexchan]

a dripper like what they give you in the ward?

 

[SkYwAlKeR]

feed glukosa into ur engine??

 

[drexchan]

probably saline too...

well.....da water injector suppose to shoooot directly to TB....thus inprove da water/air mixture....but spray direct to airfilter i dun think dat is a good idea

this mod is possible to add performance as it cools down de air....

n it has been done b4.. check out de lastest Hypertune vol 50.. (bumper issue).. done on a supercharged SGTi. they called it de "water injection"...

not new, used by many racers. I surprise not many people (locally) know this.
A lot of rally drivers apply this in europe.

search "aquamist" in goggle & you see the host of cars (enthuasist) applying it

remember "feed water vapour"; not "volumes of water".

This mod is possible and it has been used for WWII planes to cool down the engines. Cooler engines, better performance. Should be able to apply to cars. Some used it as a fuel saver. A friend of mine sold 10 unit's of this in singapore years ago for $350. All DIY from fish tank valve and piping.

so...possible if done properly huh? :albertein

risyia : yunno who to ask ma....;)

Hi Tombstone,

I know that Gerard has a water injection system done to his supercharged SGTI but his system is a complex system.

What I am suggesting is just a simple system which might or might not work.

The only fear is I suppose whether the water droplets passing thru the MAF sensor will damage it.

I got a feeling the wet air filter will only allow fine droplet thru and not stream of water in and thus damaging the engine.

I'm know how to do this ,for those who are interest PM me
i'll send you a diagram for FREE

 

[khguan]

A329878,

just share de diagram here la... mayb we can discuss about it...

 

[rattan]

yeah just post it here... im also interested

 

[tykoh]

water injection ah? hehehe.... i'm interested too... post it here and share it lah.... maybe can increase some HP also... :P

Can this use for turbo car???

 

[gavan]

maybe turbo car can use better compared to the normal car lorr....cause if can feed the water before the turbo, by the time it reach the TB, the water also become vapour adi, then more cool the air as its cooled furthermore by the intercooler ;) i think lar, theory wise maybe can lar, butthen dunno the water mist/droplets will spoil the turbo or not, not sure lorr.. :(

but for NA car, how to make it into vapour wor?? the intake there also not say very very hot also...but i think its hot enough to vapourize the water lar tho, and erm, wanna ask, carb engine can use aR? scared masuk air the carb, chia lat...how aR?? anyone got try before on carb engine??

 

[A329878]

My drawing is an Excel file just a simple drawing .
Share with those are interested !! :_:
If feel this are useful please sticky on DIY forum

Thank you and happy DIY

thanx for da idea... dat is almost like wat Drexchan did last time... everything is de same except he used de "fish stone" inside de water for better evaporation....

tested it... not much diff... y?? this thing works when ur car RPM is low or idle as de vacuum is high... when u WOT.. de vacuum is same as de atmosphere pressure... so no vacuum...

 

[A329878]

It may wrong vaccum hose you connected ........

 

[khguan]

this i duno... which hose u connect?

 

[drexchan]

well, actually, if you are cruising with any vacuum reading on thegauge, there will be bubbles.

It works.. just that there are some technical issue on the design of the system that put the project into KIV.

About the vacuum hose, all hoses with a vacuum generated by the engine has the same reading. So it doesn't matter which vacuum hose is being used.

Once can choose either the PCV or FPR hoses. Just don't cut the brake servo vecuum hose.. haha!

 

[drexchan]

another thing is that..

if the PCV or FPR hoses is used.. most of the water vapor will go to the 4th cylinder because these hoses are normally connected at the end of the intake manifold.
