Woodward PG-07 controls Sequential spark ignition

Sequential spark ignition

PG-07 controls the combustion process through sequential spark ignition. By driving

the smart coils, the system ignites the air-fuel mixture with precision timing

for optimal combustion, thus improving fuel efficiency. The rapid, high pressure,

more complete combustion yields an increase in torque and a decrease in

hydrocarbon emissions.

LPG and natural gas engines

An inline Woodward L-Series fuel trim valve controls fuel delivery based on a PWM

signal from the ECU.

The position of the trim valve biases the output pressure of the fuel flowing from

the regulator. The feedback voltage from the oxygen sensor determines

if the fuel delivery needs to be increased or decreased.

Sophisticated software modeling maintains optimum performance and response

throughout the life of the engine.

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.
