Abstract
The present invention provides a cost-effective method and apparatus for controlling engine speed. One embodiment generally comprises a controller and a linear actuator. The controller generates a plurality of voltage pulses having a duration and frequency related to a difference between a desired engine speed and an actual engine speed. The linear actuator converts the plurality of voltage pulses into a throttle position.
