Just some information I am sharing for general use, 12v application using calibration fluid 40° Celsius @ 100BAR.

5x0.010" Sac nozzle - 1.825LPM
5x0.016" VCO nozzle - 4.136LPM
5x0.018" VCO nozzle - 5.092LPM

Do you have information regarding the difference of a 5x.016" VCO and Sac nozzle. Just wondering if the VCO flows that much more/better than the Sac nozzle.
 
I did not have a 5x0.010" VCO flowed to compare, the flow difference between the nozzle types of the same hone size would be marginal.
 
Just curious why these measurements are @ 100 bar when typical pressure is nearly 3x that amount and what the additional pressure does to flow?
 
It is the standard measure used, and the pressure seen is 1200BAR and higher.
 
Opening pressure yes, the injection pump's peak pressure is much higher, varying depending on the pump used.
 
Is the injector itself seeing "1200BAR" or is the delivery valve limiting the pressure to the injector? Where is the "1200BAR" measured at?
 
The injector can see up to the peak fuel pressure capable of the injection pump. The pressure is measured at the fuel outlet of the injection pump.
 
If the injectors were set to pop at the pumps max output press you would have very little duration.
 
So if I understand correctly the pop off pressure is a happy medium of atomization and duration?
 
Not exactly. The injector itself doesn't control duration, the cam profile in the pump plays the major role in that. Just saying that if the injectors were set to pop at the MOP of the pump then IF the injectors popped they would only be open for the very small amount of time the pump was making MOP.

That’s not quite what I meant. I guess what I was trying to say was if the pop was set too high the IP would run out of push before the injection event should have been over. For instance if the injectors where set to pop at 450BAR they would not stay open as long as they would if they where set at 300BAR ? Hurting performance vs. helping?
