Woodward PG-07 Power Generation & Stationary Control System

APPLICATIONS

Woodward’s PG-07 control system controls engines in generator sets, pumps,

and other stationary industrial equipment.It controls spark-ignited engines fueled by

LPG (vapor or liquid), natural gas and/or gasoline. Suitable for engines ranging in

size from 25 HP to 250 HP (1.0L to 8.1L). The highly accurate, closed-loop control

system helps OEMs and packagers comply with local emission standards

while providing discerning customers with advanced capability for remote monitoring

and control to reduce fuel consumption and increase engine life.

PG-07 provides accurate and reliable performance control over the service life

of the engine in the extreme operating environments typical of heavy-duty,

stationary industrial applications.

DESCRIPTION

PG-07 delivers precise and fully integrated control of fixed-speed, stationary industrial

engines.

Using proven, reliable components of Woodward’s MI-04 closed-loop control

system and the L-Series electronic throttle, PG-07 monitors and regulates

functions of the following engine subsystems.

Fuel Delivery

LPG, natural gas or gasoline

Spark-Ignition

Smart coils

Air

Electronic throttle

PG-07 commands full authority over spark, fuel, and air. This integrated approach

permits precise governing and air/fuel ratio control while remaining flexible enough

to handle transients. The control algorithms are model-based, feed forward,

adaptive strategies. Continual updates to the adaptive parameters allow

for more responsive control.
