'Furthermore, I see a problem with low temperatures. The water will unfortunately freeze. Adding antifreeze would be very annoying for the participants due to the extreme smoke it would produce. If alcohol (such as spirits or methanol) is added, it becomes uneconomical.' Otherwise, I think the idea is very good.

You are using the term "Verpuffung" incorrectly.

Hi,

Ouch, that hurts. You shouldn't look at the water content in isolation, as diesel fuel and high pressure/temperatures are also involved in the combustion process.

It's clear that you lack practical experience in applying water injection, and therefore also lack comparative data.

Once again, regarding the basics:
No steam is injected into the LL section; instead, extremely fine water droplets are introduced, and these droplets no longer exhibit the dew point you mentioned.
Even if the intercooler temperature is close to the normal boiling point of water, no (complete) vaporization still occurs.

No, this system only works with pressure!

No, not with the system that applies here!

When it's freezing and the low-temperature coolant (LLK) system is not functioning properly, water injection is not as effective in lowering the LLK temperature. Otherwise, the windshield washer reservoir can also be tapped, especially if the windshield washer fluid contains antifreeze additives such as alcohol. You can't smell anything from it.
But never use coolant antifreeze when injecting water!

Hi Comco,
I think we should stop discussing this further, as it seems like some people aren't understanding what's being said.
Find out what menthol is, what methanol is, what a deflagration is, etc., before you start writing things randomly.
