Abstract
An apparatus for remotely controlling the speed of an engine includes a housing and a control knob. A position shaft is fixedly connected to the control knob for rotation therewith and a position gear is fixedly secured to the position shaft for rotation therewith. A rotary encoder has a shaft in operative engagement with the position gear such that rotation of the position gear rotates the encoder shaft. The rotary encoder generates output signals based on a direction of rotation and angular displacement of the control knob. A processor receives the output signals from the rotary encoder and generates output signals proportional to the direction of rotation and angular displacement of the control knob. A primary engine control unit is remotely located with respect to the remote housing for receiving the output signals from the processor and directly controlling the speed of the engine based upon the received signals.
