water + hot gas + cilinder = ?

[PedroCG]

hi,

I've searched the foruns and find nothing similar to this... lets say a gas is compressed in a cilinder, now, if you inject water... the water would turn to steam, but how? volume would be constant, entropy? internal energy? if someone can point me in the rigth direction i'd be tankfull

Actually, I think his son Dave took over the company...or at least he seems to handle the technical aspects of the business.

Great subject!!
I've heard that some racing engines use water injection...if there is a loss in power then why they use it?
For the temperature?

"Suppression of detonation at high boost."

Pat has a reputation for responding tersely to flip and/or poorly formulated questions. ;-)

The extended answer is, ..."thereby allowing, via higher boost, increased detonation-free power. "

Squirting in an as-uniform-as-possible two-phase mixture of air and water droplets and then compressing it, is thermodynamically different from compressing air only and then squirting cold water into it.
