Fuel pump
The two fuel pumps are supplied by a relay controlled by LIE control unit. For safety reasons the pump relevant to
cylinder bank 1-6 is controlled by LIE control unit of cylinder bank 7-12 and vice versa. They are roller type positive displacement pumps with permanent magnet energizing.

Injectors
The task of the injector is to deliver the amount of fuel required for the engine operation: The fuel is injected into theintake duct, immediately upstream of the intake valves.
As the pressure differential is constant between inside and outside the injector (due to the regulator), the quantity of
fuel delivered, with the same electric power depends only on the opening time, established by the control unit.
The injector is the “top-feed” type with the fuel supplied from the rear of the body ( H-Fig.4), where the electric
winding ( ' ) L J ) is also located, connected to connector ( ( ) L J ). The needle ( % ) L J ), integral with the anchor
( C-Fig.4 ), is thrust against the seal seat by a spring ( I-Fig.4).

When the current ceases, the shutter is called back into position by the spring ( I-Fig.4).
