here i can contribute one of my measurement of 0 445 110 036 injector (from 2.2 HDI 98kw engine),
on the machiene.

based on that you can to very good extrapolation of injection duration map rail axis, and iq axis,
to get "real stuff".

For brave guys, measurement of 1600 or 1700bar would be good.

Ecuedit, where did you test this nozzles., or is this some special program that can be possible to buy somewhere ?

I was searching for the flow rate of some injectors in a z19dth engine (150 hp). Bosch ref: 0 445 110 159
And i have found some documents.
boschinjectortestplans4web.pdf

But i have a doubt about the measurement units: "Delivery cc/1000" and the calculations.

May be they are 1000 pulses?
I think it is explained here: http://performancefuelsystems.com/InjectorFlowCurve-TechCorner.htm

For example: 0 445 110 159
Rail pressure: 1350 bar
Pulse width: 900 msec
Delivery: 95 cc/1000 pulses

Flow rate = (95 cc/1000 pulses)*(1 pulse/900 msec)*(1 msec/0.001 sec)*(3600 sec/1 hour) = 380 cc/hour at 1350 bar

Any thoughts?

1. The data specified in the given document, mismatch data Bosch.
2. The flow rate cannot be counted up under this formula because real injection by injector is unknown.
3. Term SOI which is used in this document, it not SOI in maps.

It is impossible 0 445 110 036 to increase on atomizers pressure to 1600 bar, especially to 1700 bar. They are calculated on work at pressure 1350 bar.
If you increase pressure to 1600 bar specified by you they will very quickly break.

Soi in the tables is referring to the pressure when fuel flow happens, ie injector opening pressure.

running 200.000km and not braken. Even 1800bar for 4 months. Hybrid bosch pump and all good. That injector does not break that easy. Tested on several hdi for racing and everyday ride.
