Re: Injection pressure and the various types of injectors
The IP numbers that people say that come from the 5:1, 6:1,and 7:1 I believe are way incorrect. Like 3000 icp
in an a code would in theory have 21,000 psi
I believe that that would only be accurate if the nozzle were not releasing fuel. When the nozzle opens and releases fuel there is a pressure drop and since the hybrid pushes fuel faster it is able to keep its pressure higher while the nozzle is open. I hope that what I am getting at make ssome sense if not I will try to explain more.
Actually when the nozzle opens it is at a lower pressure than peak. This is called nozzle opening pressure which is I think some where between 3 and 5,000psi. Also restriction to flow causes pressure. So the smaller the nozzles the higher the psi
on any injector.
Just my .02 if Im wrong I am sure some one will correct me
