Abstract: Computerized system and method for controlling an internal combustion engine are provided. The system includes a speed-setting device operable to supply a signal indicative of a desired engine speed. A speed sensor is coupled to the engine to supply a signal indicative of the actual speed of the engine. An electronic control unit is coupled to receive the respective signals indicative of desired engine speed and actual engine speed. The control unit in turn includes a comparator configured to compare the respective signals indicative of desired and actual engine speed relative to one another and supply a comparator output signal based on the magnitude of any differences therebetween. A processor is responsive to the comparator output signal to adjust one or more engine operational parameters of the engine.

Abstract: Computerized system and method for controlling a plurality of internal combustion engines are provided. The system includes a respective speed sensor coupled to a corresponding engine to supply a respective speed sensor signal indicative of each engine's speed. The system further includes an electronic control unit coupled to receive each respective speed sensor signal. The control unit in turn includes a comparator module configured to compare each speed sensor signal relative to one another and supply a comparator output signal based on the magnitude of any differences between the engine speed signals. A processor module is responsive to the comparator output signal to adjust one or more engine operational parameters of one or more of the plurality of engines.
