INJECTION PUMP





The Robert Bosch VE injection pump is a rotary distributor type pump. This pump performs four basic functions of:

1. Producing the high fuel pressure required for injection.
2. Metering the exact amount of fuel for each injection cycle.
3. Distributing the high pressure, metered fuel to each cylinder at the precise time.
4. Varying the timing relative to engine speed.





The pump uses a single plunger to develop and distribute the high pressure required for injection.
