Subzero Temps on Water/Meth Injection
Presently I am running Water Only @ 14psi @ 45C Air temps without Intercooler.
I came into an idea of using a phase change cooler fixed to a Maze Aluminium Water Block. The block will be divided in two sections, one water/meth flow and the other fuel flow. This way fuel will also be cooled. Water In will come from Water injection pump out to nozzle while Fuel In will come from Fuel pump out to fuel rail. The chiller goes to -60C on the block in just 2minutes without heat sources with ambient temp of 27DegC. -Water will freeze in 30sec @ 0DegC -Water/Meth mix 50/50 will freeze in 1 minute @ -35DegC -Gasoline freezes @ -45DegC -Straight Meth Does not show symptoms of freezing @ -60DegC Temperatures were tried and tested in real time using an laser temp gun. The chiller work with 230V A/C power so a power inverter is needed to operate it. You don't want any of the liquids to freeze so the chiller will be operated via a digital temperature controller that the user sets switch off temp via a high power relay. When using only water cutoff will be set at 5DegC When using 50%water/50%meth cutoff will be set at -30DegC When using 30%water/70%meth cutoff will be set at -40DegC Presently I have an issue starting the chiller with the Inverter going overload at startup. I need to check whether the 2000W inverter is capable or else there is a need of a better battery or capictor/stabilizer. Project will be done within the next weeks so any suggestions are appreciated prior to completing setup. Last edited by parmas; 21-07-2013 at 07:25 AM. |
