[Diy_efi] New BMW 760, fuel pressure, direct inject

[Mike]

Hi Chaps,

Just curious if anyone knows the fuel pressure/injector rail
pressure the new BMW 760 operates at - as its direct injection
it cant do the batch fire thing and would need quite a higher
pressure to squirt the same amount of fuel at the correct
time or would it have so much higher a flowrate, then theres
the compromise of head geometry to fit the injector,

I've heard rumours some big truck/movers diesels run as high
as 20,000psi direct inject pressures <phew>



Kind Regards  ~`:o)

Some say there is no magic but, all things begin with thought then it becomes
academic, then some poor slob works out a practical way to implement all that
theory, this is called Engineering - for most people another form of magic.
