injector voltage?

Post Sat Jul 22, 2006 1:54 pm

does any one know what voltage the injectors work on, on a 318is?

i would have thought it would be 12V but i thought i better check.

i want to make them "inject" when i dab a 12v supply on them so i can run carb cleaner through each one when its on the work bench.

In order to make then inject, your going to need a decent pressure / flow rate of cleaner.... they must be 12V, no reason to regulate the voltage to anything else that i can think of.

why do they need pressure? i was just going to put some pipe over the inlet fill it with cleaner and let gravity do the work.

the fuel regulator is 3bar on the ETK

Because i can't imagine the bore thought the injector being that large... I've never played with one, so perhaps i had better shut up!!!

You need LOADS of fluid to pass over any muck inside in order to dissolve it away, Ideally you need to feed it with 3Bar to see the injector pattern produced at the tip...

Let us know how you get on

marks right, you wont get the results you're looking for if the pressure isnt there

ive, finealy got rould to doing these, ask i type there sat in the ultra sonic bath to break up most ot the crap, ive cleand both ends carefully.

sound like i need to rig up some sort of pump then.

are the orings on either end any different to ordary orings? are normal ones petrol resistant/proof?

i want one of these!!

id get the right o-rings just to make sure. i think they are some special type, coz of the petrol. otherwise, it would just decompose the rubber!

i think i probably will wait and get the right ones,

i just asked as i wanted to get it done today but the BMW parts place shuts at 12.30.
