Abstract:
Computerized system for controlling a plurality of internal combustion engines, the system comprising:a respective speed sensor coupled to a corresponding engine to supply a respective speed sensor signal indicative of each engine's speed;an electronic control unit coupled to receive each respective speed sensor signal, said control unit comprising: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 therebetween;a processor module responsive to the comparator output signal to adjust one or more engine operational parameters of one or more of the plurality of engines, the one or more engine operational parameters being responsive to respective control signals from the control unit to affect engine speed to reduce the magnitude of said engine speed differences so as to maintain each engine speed within a predefined range from one another.
