Subzero Temps on Water/Meth Injection

[paveltol]

Did the mixture crystallise?

Does anyone run water-methanol/methanol injection during winter with ambient temperatures reaching -35C?

Today tested the setup @ 4DegC Tank mixture and for several runs got same results compared to a 32DegC tank temp.

Conclusion :

The theory of cooling the tank temperature with any means of cooling will not gain any decrease in inlet temperatures. The setup works with pressure and pressure generate heat to get the mixture to mist. Although this was known from the beginning, I thought that I would be able to vaporize a mist cooler by cooling the mixture itself.

In my opinion now, the better the atomaization of the mist the better the cooling. So that makes 200psi pressure and a 300cc nozzle better cooling when compared to a 150psi pressure and a 300cc nozzle at the same flow rate. When I say better I don't know how much better would that net but I would like to hear opinions or actual tests.

Another thing, if the injection works with heat and pressure, would having a hotter tank mixture actually helps ?
