What I understand is, AB's require less oil than AD's for example. These are single shots with EH
7 hole at .008, which equates to 190c with a flow of 29 liters per minute.
I have read about the plungers and workings of these injectors but is a little hazy in my head as to how each combination works. There is another thread on that, I imagine you have all seen.
Thanks IMELMO that makes sense.
Here it is from HOTWHEELS:
Codes- All powerstroke and T444Es come with A code injectors. A code injectors have a 6.0mm plunger and a 16mm intensifier piston. What this does is multiply the ICP
so that injection pressure is adiquate but not having to have huge amounts of ICP
like say in the 20,000 psi
range. This difference give you approximately a 7:1 difference and therefore increases your injection pressure 7 psi
for every 1 psi
So, with that said, if the nozzles are changed out to flow more fuel, with greater effeciency as well as higher ICP
, better atomization is achieved.
