Partial combustion generates acid compunds rahtehr than free gasses. So when it gets to teh catalyst, furirst it's done dmamge on teh way and second the catalyst has to first break down the acid and THEN combine to stabilise.

also I am talking about water injection as an entire cooling system not a intercooler or whatever.

A given, intercooling and charge cooling are well undestood and used.

also a good note that with water injection cooling with a no-loss system

Ohhh, wasn't thinking zero-loss
So how do you recover the water ?
Especially as some of it WILL have combined to form acid compounds.
How much energy does it take to keep a cold surface condensor cold ??
