engines ignitions fueling ....

just reading through
http://www.max-boost.co.uk/max-boost...ion_deeper.htm
and simular pages,
Just wondering, would it be possible to spray a fine mist of water into the engine, and it have a positive result,
just curious because a petrol engine runs off the hydrogen in the fuel doesnt it?
or is it as simple as water put fire out

Just interested thats all

My understanding is the water injection cools the charge mixture a bit & makes the a/f mix less prone to detonation - so you can run more advance, higher compression ratio, etc.

I think the whole idea of spraying a fine mist in to a turbo engine is to cool the intake gases which produces higher boost levels.
I dont think spraying it in to a naturally aspirated engine will have any effect.
But just for giggles spray a fine mist of water over a candle and see if it ignites the hydrogen in the water

Yep its a good idea,

1: it cools the mixture (helping reduce chance of detonation)
also means that the mixture is denser and more combustable
2: again as water doesnt ignite it reduces the chance of preignition+detonation
3: when the fuel/air/water mixture if ignited the water doesnt burn but when the fuel+air reach a certain temp, the water vapourises creating steam, this inturn creates more pressure in the chamber and increases power!

i don´t think you will win any HP on it - they use it on turbo motors to cool down the tempeture on the intake air - but you don´t have a very hot intake air so you wan´t get a bigger amout of air in your combustion chamber and thats what it´s all about!

but try it and let os know what gain off HP you get!
