The 4093766 Diesel Fuel Injection Pump Is Designed For The Cummins 6BT5.9 / 6B5.9

The Cummins 4093766 diesel fuel injection pump is a mechanical high-pressure fuel injection pump designed specifically for the 6BT5.9 / 6B5.9 series diesel engines. It is manufactured and modified based on the Bosch P7100 platform. The fuel injection pump controls the fuel injection amount and timing through mechanical speed regulation, pressurizing low-pressure diesel and accurately injecting it into each cylinder to achieve efficient combustion and stable output.

Main Functions

Provides high-pressure fuel – pressurizes low-pressure fuel to approximately 700–1000 bar;
Precise Injection Control – Accurately controls injection timing and quantity based on engine speed and load;
Ensures combustion efficiency – Provides stable and uniform fuel atomization to enhance power output;
Speed ​​Control and Energy Saving – The speed governor automatically adjusts fuel supply to maintain smooth engine operation.
