Apparatus for an engine control system

Abstract

In one embodiment of the present invention an apparatus for controlling one or more engines by synchronizing the functions of two or more electronic control modules includes a master electronic control module, one or more slave electronic control modules, and one or more data links for transferring data between the electronic control modules. Engine control and monitoring functions are divided between the master electronic control module and the slave electronic control modules. The present invention may be used to control and monitor dual fuel engines and engines that operate on one type of fuel. The master electronic control module may transition operation of the engine to the diesel fuel only mode in the event of a failure of any dual fuel mode specific components. The master ECM coordinates timing and speed of fuel injection to engine cylinders using input from an adjustable engine speed command device and a speed sensor connected to each engine. The loads driven by the engines may be allocated evenly or unevenly.
