Cold Start Injector Flowrate?

Thanks for info...compared to 20-26cc/min, that would mean the CSI flows 5 times the rate of the cylinder Injectors...this supports my theory that the (much smaller) cylinder injectors may be frozen from fuel gum (a real problem here in the US with fuel deteriorating from the alcohol they add!), but the CSI is not, since it is so much bigger.

Symptoms for an 1800E no-start after 6months being parked, are that it only runs during cranking, and stops after cranking...this suggest to me that FuPu is charging fuel rail and CSI is injecting, and everything including Ign are OK, but only CSI is supplying fuel. I suggested owner also check for injector pulses with Ign ON and while opening Throttle.

Hi,

I disagree. As I wrote before, a normal injector has a mich higher flow rate. Statically 265 to 380 cm³/min . But they are not operated statically.

What happened to my posting?

Repeating: I must have understood...rephrasing the question...all test conditions (fuel rail pressure, time of energization, etc.) being equal, what is the comparative flowrate of CSi vs cylinder injector?

Ron the injector at your cylinder will flow 265 - 380 ccm/Minute.
Your CSI will flow 20 - 26 ccm/Minute.

Hi Rudiger,

objection dear sir. As I wrote above CSIs of D-Jetronic have a flow of roughly 100 ccm/minute. I do not know it exactly for this 0 280 170 010 . It was also used in BMW and later replaced by 0 280 170 024 that shows a flow rate of 85 ccm/min.

Wherever you have this 20 - 26 ccm/minute from: It is not the static flow rate of an injector nor of this CSI.

Hi,

I do not know what Ron means by

Again: I diasgree with Ron*'s theory. But I cannot read Facebook entries. I think it is better if you ask the owner of the car to log in here and ask his questions.
