ABSTRACT:
The engine governor outputs a pulse width modulated actuator control signal at two or more frequencies to improve actuator performance. In one embodiment, the control signal has a frequency of about 60 to 70 hertz when the throttle is nearly closed, and switches to a frequency of between 5 to 30 hertz once the throttle is between 50 to 75 percent open. In a second embodiment, the frequency of the actuator control signal decreases in a linear manner from 60 to 70 hertz to between 5 to 30 hertz as the throttle is opened from a closed throttle position to wide open throttle. A decrease in frequency with increased throttle opening provides additional control signal off time, thereby allowing the magnetic field in the actuator to sufficiently dissipate for proper dithering action.
