2.4.3.4 Rail Pressure Sensor, Setpoint Map and Controller
The rail pressure sensor is the most important sensor as injection quantity is directly re-
lated to rail pressure and an incorrect sensor curve PRAIL_CONV can result in incorrect in-
jection quantity which may lead to serious engine damages.
Maximum allowed system pressure should not be exceeded. In a one actuator concept the
mechanical pressure limiter valve PRV mounted directly in the fuel rail is only designed to
open and protect the system very few times during its life time, which must be considered
in rail pressure setpoint map calibration.
