Woodward PG-07 CONTROL SYSTEM FEATURES

Gasoline engines (up to 4 cylinders)

The ECM and sensors provide the computational power, algorithm logic, sensor

inputs and control outputs to control the system. The ECM receives signals from

the sensors, digitizes these signals, and then through algorithms and

calibration maps computes the desired output response to manage

fuel, spark and air to the engine. The ECM also provides a variety of other

functions and features, including system monitoring and diagnostics to aid

in maintaining efficient system operation and auxiliary control.

All gasoline specific components are automotive production parts and

validated to strict automotive standards.

PG-07 CONTROL SYSTEM FEATURES

 Closed-loop control of air-fuel ratio improves equipment durability by reducing

maintenance, fuel consumption, and engine component wear.

 Control strategy ensures optimal transient performance for efficient system response.

 Comparisons of actual engine operation to expected values allow the system to

compensate for wear, tolerances and adverse operating environments. 

This improvement in operating economics is a result of the sophisticated software

models in the PG-07 system.

 Programmable idle speed control includes speed setpoint modifications for

coolant temperature and speed selector switch input.

 Monitoring and diagnostic communication via two CAN Bus interfaces

(J1939 protocol) allows immediate assessments and corrections either on-site or remotely.

 Individual diagnostic codes detect functional faults, intermittent faults, sensor

and actuator failures, and engine protection problems.

 Malfunction indicator lamp (MIL) annunciator allows instant analysis and troubleshooting.

 Extensive engine protection features include monitoring of engine coolant

temperature, oil pressure, and overspeed.

 Fault conditions can be calibrated to trigger a limited operating mode for

diagnostics and troubleshooting.
