In a common rail (CR) fuel system how are injection pressures are maintained?

Question

Quizplus · Accepted Answer

Injection pressures are maintained in the entire rail assembly and injector circuit in a common rail fuel system. The fuel is supplied to the rail assembly at high pressure, usually between 20,000 and 30,000 psi, and this pressure is maintained throughout the rail and injector circuit to ensure consistent and precise fuel delivery to the injectors. This is achieved through the use of pressure regulators, sensors, and control units that work together to maintain the desired injection pressure.
