Injector question.
« on: 13 October 2011, 12:15:22 »
The brown plastic/bakalite ? washers/seals on the end of the injectors.Are they particularily important ? I have 5 of 6 missing.
Currently have a set of 3.2 injectors on the car (2.5) and the car spends most of its life running on LPG anyway.Would prefer to swap back to the original injectors if the missing bits arent going cause a problem. :-\ Are they replaceable ?  Tia.

You might find the O rings get sucked off the end of the injectors and into the intake without them. :-\

Albs - I'd normally suggest trying one of the helpful breakers on this site ;D ;D ;D

Sure Twigs/Pinky/EP etc etc can sort you one if you're not expecting one in soon yourself :y

I've got 2 sets of 2.6 injectors here so, assuming they are the same, I'm sure we can sort something out next week.  :y

I hope I'm not breaking any rules by mentioning this in the General Help section!  :-\ :P :-X

IIRC, 2.6/3.2 have different injectors and a higher fuel pressure than 2.5/3.0. The question is: does this matter? If they flow at roughly the same rate and have the same electrical characteristics probably not. Does anyone have the two part numbers so I can compare specs? (It's the Bosch number - 0280 xxx xxx)

Got 3.2 injectors complete with fpr etc on there at the moment.Car seems to take a bit longer to start from cold than I would expect,and I seem to use more petrol than I woud like.May not be connected though,planning on changing the plugs at the next service in a few weeks time,so that could improve the percieved problem. :-\
No idea on P/N btw,and if there is one on an injector,probablt too small for me to read. ;D

On the FPR - 3.0Bar. 0 280 160 560.

It doesn't to me either, until we have the part number of the other injectors. ;)

Basically, it's flowing 203.9 cc/min at 3 BAR fuel pressure.

The 2.6/3.2 injectors work at 3.8 BAR IIRC, so the question is what is their flow rate at 3.8 BAR?
