[2] SUPPLY PUMP

The  supply  pump  corresponds  to  conventional

injection pumps but pressurizes the fuel to more than 2

times that of conventional pumps for delivery to the rail.

The supply pump is made up of an intake adjustment

valve (SCV) (3), pressurizing part, overflow valve (4), IO

valve (6), and zero delivery drain (5).

NOTE

• Rail pressure changes based on engine model

and engine conditions.
