EGR - exhaust gas recirculator?

I only can find PCV hose on my engine..and that's where I gonna inject water into my engine, straight to the manifold bypassing the MAP sensor.

i heard if u use the vaccum point, u need to rev it high to fine tune it...... as it will suck very strong during high rev thus tuning it from that point is more accurate.

how about aluminum..can aluminum piston rust...

Savvy's piston is made by Mahle...they only offer aluminum pistons for non-commercial vehicles...

according to my noobie form 5 theory in chemistry, aluminium rusts easier than iron. in fact when u put aluminium and iron together, the aluminium will rust in place of the iron.


[prick mode]
but if u wan me apply more of my noobie chemistry theory, u can say that aluminium actually doesnt rust. rusting is the corrosion of iron .
for aluminium, its called corrosion/ oxidation.

haha quite useless in this contex!

btw,when you compress n2o,ur actually feeding more o2 for combustion hence increasing power right?will h20 compress give you more o2 as well?
lolz,poor mans nitrous

i dont get it, why would a piston rust? our fuel is of hydrocarbon or short, carbon...

while IF there's rust on piston, it's oxide..

if not mistaken, carbon + oxide + heat = CO2+H20..meaning, even if there's oxide or laymen term rust, it'll still be removed..

dat's y we didnt hear ppl complain of inner part of exhaust system tubing gets rust..usually the rust sets in from outside..

if pistons can get rust from inside... imagine the by-product of fuel burning... water.

aluminum wont rust if its purely aluminum...
piston is something mix alu+iron+carbon etc..
how about valve..its iron

aluminum will rust. its just that the result is an oxide that is tougher than the original stuff itself. that layer of oxide will protect the unoxidized stuff underneath.

hmmm...how bout ultrasonic mist generator???
those mist producing things u see on those rolling crystal balls in shopping complexes....

put it in a bottle then put a flexible pvc hose on the top of the bottle connecting it to the intake near the butterfly valve. the suction shud suck the mist into the engine

i thought of this idea before...


BTW... the main concern is NOT rust... your engine is operating about 150-200C at idle... and up to 450C at max rev... at that temp... water will immediately turn to steam and out of your engine... what you need to worry most is unburnt petrol that sit in the piston when you switched off your engine. this with the carbon deposits and also engine oil vapor will chemically react and become corrosive.

also what you SHOULD concern about water injection is the water droplet size... if it's too big. the water droplet might cool the piston TOO fast causing the piston top to pit. IF the water volume is too much, you might suffer piston lock as water cannot be compressed...

i've been running direct injection with mist nozzle for the past 3 years... no rust or whatsoever on my piston. i'm using about 3L of water to every 30L of petrol...

someone willing to try it???

wah .. dead thread come alive again !!

is the site above for real?

engine suction power would not be strong enough ler...

its an electrolysis system where u use the car's power source and u seperate water into its basic component. when hydrogen is burnt with oxygen to become water, it releases an amount of heat as energy

Tried it already, not much effect for my wira...

ur electrolisis power not strong enough... u need to produce more hydrogen...

for the water injection system,its da same as sucking in water eg. from rain or puddles thru ur air filter and that is strongly not recomended,so why should letting water droplets or mist into ur engine do any good?

Have you ever notice during rainy days your engine performs better? There you got your answer
