Fuel Pressure Regulator: Description and Operation
Injection Pressure Regulator
The Injection Pressure Regulator controls injection oil pressure. An electrical signal to a solenoid creates a magnetic field which applies a variable
force on a valve servo to control pressure. The quantity of fuel delivered to the combustion chamber is proportional to injection control pressure.
An open circuit will result in minimum oil pressure and a no-start situation. A short circuit results in maximum oil pressure, and is limited by a
mechanical pop-off valve to 27,580 kPa (4000 psi).
