Where is the fuel control actuator located?
The Fuel Control Actuator is located at the rear of the high-pressure, fuel injection pump (Fig. 13).
What is a fuel pump actuator?
The Fuel Control Actuator (FCA) or Fuel Pressure Regulator is an electronically controlled solenoid valve. The ECM controls the amount of fuel that enters the high-pressure pumping chambers by opening and closing the FCA based on a demanded fuel pressure.
Is a fuel pump an actuator?
Actuator Description The actuator is installed in the EFC cavity of the PT fuel pump. The actuator controls the engine speed and horsepower by controlling the fuel flow to the injectors. The actuator shaft will turn when the current from the governor control changes.
What is engine actuator?
An actuator is a component of a machine that is responsible for moving and controlling a mechanism or system, for example by opening a valve. In simple terms, it is a “mover”. When it receives a control signal, an actuator responds by converting the source’s energy into mechanical motion.
Where is the actuator on a PT fuel pump?
The actuator is an electromagnetic rotary solenoid valve. The actuator is installed in the EFC cavity of the PT fuel pump. The actuator controls the engine speed and horsepower by controlling the fuel flow to the injectors.
How to remove the actuator from an EFC fuel pump?
A 45 chamfer is at the EFC actuator mounting surface. Actuator Removal From an EFC Fuel Pump Housing Remove the actuator wires and capscrews. Caution: Do not pry the actuator from the housing. This can damage the actuator shaft and make it stick. Twist tho actuator and pull it from the housing. Remove the three O-rings from the actuator.
How to repair the fuel filler door release actuator?
Repair procedures 1. Remove the trunk room left side trim. 2. Open the fuel filler door and remove the housing (A). Do not reuse the fuel filler door housing. 3. Remove the fuel filler door release actuator (A) after loosening the mounting bolts.
When does the actuator turn on a Cummins Engine?
The actuator shaft will turn when the current from the governor control changes. The current from the governor control will change when the magnetic pickup senses a change in the engine speed. The throttle shaft is set in the full open position. The fuel flows through the fuel pump to the actuator (EFC) cavity.
