A radial, 3 piston pump with a gear type fuel pump attached to the back, is used as the high pressure pump for fuel pressure generation (Refer to WARNING ). See Fig 1.

The pump is driven by the timing belt. Pressure is generated independently of the injection process. The pump is lubricated with diesel fuel and is not responsible for fuel injection timing.
