Default So what is water injection?

Water is bad for my engine, right? So why would I inject water into it?

If instead of the richer mixture about 10% (by mass) of water would be injected in the intake charge (0.008 kg Water/kg air), the high latent heat of the water would cool the charge by 18 degrees, about 4 times the cooling effect of the just a richer fuel mixture. The added fuel for the rich mixture can't burn because there is just not enough oxygen available. So it does not matter if fuel or water is added.

Doesn't it make the air expand when the water turns to steam?

As I understand it yes, but that's a good thing for spool.

the water would already be highly atomized.... and injected in super small quantities..... So I doubt that it's expansion would impact anything much
