rail pressure sensor function

Typical Common Rail Fuel System Issues - Diesel World- rail pressure sensor function , Starting with the basics, a high-pressure common rail fuel injection system (HPCR) used in the GM and Dodge heavy-duty pickups since the early 2000s is quite different from the previously used Pump- Line- Nozzle (PLN) systems (like those found on a P-Pumped Cummins for example, but not like those found on HPOP equipped Power Strokes)Common Rail Injection System Pressure Control This pressure is monitored by a pressure sensor and the difference between the nominal rail pressure value and the measured one is the input signal for the controller In control terminology , the rail pressure is the system output while the position of the actuator used to control the rail pressure is the system input
