Do you mean air injection or air injectorS ?

Air injectors
are just large normal fuel injectors used as air flow control
when controlling boost levels via the actuator.
Usually found in pairs side by side.
They give precise control of boost at all levels/rpm as mapped in the ECU.
Kind of an expensive AMAL valve if you know what that is !

This is done by pulsing the injectors open/closed very fast and varying the
open time which averages out the air flow to the actuator and thus alters
boost pressure.

And air injection is an old method used to reduce emmissions in the 70's

Air INJECTION
is used on some cars to help the cat warm up quicker when the engine is cold.
This is usually done with an electric pump.
This was fitted to reduce exhaust emmisions.
This has NO performance advantages (was used on the Mk5/6 RS2000)

Cheers SECS, now i understand it

I meant air injectors and i know what a amal valve is

Is this basically just pumping extra air into the exhaust system??. Could you use this to make a car setup rich to pass an MOT??

XRTypeRS, Yes in theory you could do this subject to the air pump able
to deliver enough air at the MOT test points.

andyescos

speak to Ian@Racetek about em, he gets excited by em! and can normally get some of the little hard to find things!

XRTypeRS

Hmmmm!!!!

these are the little buggers

dony need to explain what they do as i think simon sorted that

GARETH T, You ran outside to take a picture specially in this weather ??

GARETH T

its an old photo dude,, had it on photo bucket

XRTypeRS

So you just let the boost bleed out the fuel inlet and simply pulse them as normal injectors??

xr-stu

cheers guys!!! i always wondered how air injectors worked!

so can you use boggo fuel injectors i assume?! as your just allowing air to pass through yeah?!

JesseT

Some have used old fuel injectors, but they have to be huge or very many to really work.

Fuel injectors wont work for very long at all

tracktoy

thought only fuel injectors were used?!?

Stu @ M Developments

iTrader: (12)

Nope.. fuel injectors are designed to flow fuel and as such get very very hot and fail when used without their primary coolant medium

tracktoy

the answer i was looking for was
'you need to use ****** type injectors', pmsl


worth a try though
