Bosch CP3.4 Common Rail Fuel Pumps
Bosch CP3.4 Common Rail Fuel Pumps
(OP)
I am looking for some information on some Bosch common rail CP3.4 fuel pumps for a project. Looking for information such as maximum flowrate and operating pressures. I have no idea how to get this information from Bosch, and I am having no luck finding out about these pumps through engine manufacturers such as Cummins. Anyone have any idea how I can get information on Bosch Common Rail pumps?

RE: Bosch CP3.4 Common Rail Fuel Pumps
1. Max. working pressure: 120KPa
2. Min. working pressure: around 30KPa, about 800 rev/s
This is all I can help.
RE: Bosch CP3.4 Common Rail Fuel Pumps
From what I know, this pump is usually build in 4 cylinder up to 2.2 litres. If you do the math, you get the max volume. You always have to calculate that about 20% of the fuel has to back to the tank. This is due to the fuel regulation and injector back flow.
Hope it helped
