Abstract:
Computerized system for controlling an internal combustion engine, the system comprising:a speed-setting device operable to supply a signal indicative of a desired engine speed; a speed sensor coupled to the engine to supply a signal indicative of the actual speed of the engine; an electronic control unit coupled to receive the respective signals indicative of desired engine speed and actual engine speed, said control unit comprising; 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 an differences therebetween; and a processor responsive to the comparator output signal to adjust one or more operational parameters of the engine, the one or more engine operational parameters being responsive to respective control signals from the control unit to affect actual engine speed to reduce the magnitude of the differences between the actual and desired engine speed to within a predefined range.
