Woodward's new 0154 integral linear actuator provides proportional fuel control for construction, industrial, power generation, and agricultural equipment. As the newest plank in Woodward’s platform of solutions for on-engine actuation, it can be customized to OEM requirements for diesel engines using mechanical fuel pumps.
The 0154 is available in two configurations—standard or LAPS (linear actuator with position sensor). Both actuators, along with an electronic control unit, change fuel control by applying current to move the plunger in or out. With the standard actuator, the shaft position is defined as a point between the energized and de-energized positions. With the LAPS actuator, the position sensor allows feedback to the ECU to indicate and control shaft position. This is particularly advantageous when position feedback is required for emissions control.
Purpose-built for specific diesel engines with mechanical fuel pumps, the 0154 is integrated into the fuel pump so no mounting apparatus or external linkage is necessary.
APECS 0154 actuators are suitable for installation on diesel engines. Spring force can be tailored for specific fuel system force requirements.
LAPS actuators should be used with an APECS 4800 controller for position feedback operation.
