Yes, it adjusts between 5MPa and 12MPa (50-120 BAR) dependent on the
pressure control valve.

Subject: [Diy_efi] New BMW 760, fuel pressure, direct inject
Reply-To: diy_efi at diy-efi.org

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>
