Abstract
A microprocessor based interengageable engine generator set control device that provides bi-directional communication and control via a common J1939 protocol of electronic engine control units. Such engine control units provide critical engine information and control using manufacturers proprietarycodes that are readable by the interface engine controller. Engine commands are issued by programmable software and operational input in response to information received and analyzed thereby.
