Bosch injector flow rate

by **biela** » Wed Nov 14, 2012 3:31 pm

Hello
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?

What a post! Long time I was looking for flow tables of CR injectors :clap: :thumbup:

cc/1000 = mm3

for example:

0445110002 injector
900us pulse @1350bar = fuel delivery of 50-55mm3
700us pulse @250bar = 9-10mm3

Thank you, it makes more sense if it were in us and not ms. I think that machine probably measures into a glass tube or something, which would make the cc/1000 measurement more convenient since it is measuring shots. Machines that measure with a flow meter would probably use mm3.

+1

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.
