GF07.13-P-3013C | DFI high pressure fuel circuit, function | 17.7.95 |
ENGINE 602.982 in MODEL 210.017 /217 /617
P07.13-0350-76
Design
11/26 Return flow restrictor valve
51 Nozzle holder combination (2-stage)
55/2 Injection pipe cylinder 2
90/3 Fuel return pipe for leak fuel
90/5 Fuel return pipe
L9 Needle lift motion sensor
Y23/3 DFI distributor-type injection pump
Purpose | Supplying fuel to the individual cylinders in line with the firing order | ||
Function | The fuel pressure required for injection is produced in the high pressure part of the DFI injection pump (Y23/3). The fuel in this case is supplied through the return flow restrictor valve (11/26), the injection pipe (55) and the nozzle combination (51) to the injection nozzle. | ||
