    Abstract: An engine control and input system for a device having a tool driven by an engine, includes an input and control module having one or more inputs and a controller responsive to actuation of the inputs to permit user control of at least one engine operating parameter by user actuation of the inputs. The system may include a touch screen display that displays icons to the user relating to the inputs and the at least one engine operating parameter, and wherein the touch screen display is responsive to the user selecting one of the inputs by touching an associated one of the icons provided by the display. At least one of the inputs may relate to one or more of changing engine speed, starting the engine, causing the engine to drive the tool, turning on a light, actuating a heater or warmer or stopping engine operation.

    Abstract: A system for controlling an electronic throttle body includes an engine speed setting device having a first terminal coupled to a source for a reference voltage, a second terminal coupled to a first end of a conductor and means for varying a level of resistance between the first and second terminals. The level of resistance is indicative of a desired engine speed. The second terminal outputs an analog engine speed signal indicative of the desired engine speed on the conductor. An electronic control module includes an engine speed signal processing circuit including a resistor coupled between a node located between the first and second ends of the conductor and one of a voltage supply and a voltage return. A controller coupled to the second end of the conductor is configured to generate a control signal for the electronic throttle body responsive to the engine speed signal.
