The demands upon Diesel-engine governors are becoming more stringent, and it is possible that electronic governing systems will be the best means of meeting them in the future. The power device, at least for large engines, will not be electronic (pneumatics are generally accepted for this function), but for the smaller engines an actuator based on a low-inertia geared servo-electric motor will give excellent performance while avoiding the need for an extra power source. The article discusses these matters further, with particular reference to the advantages of electronic governing and to the much improved reliability of modern components, and describes some electronic governing equipment. An illustrated description is included of the Servodyne high-power electronic governor as used with all standard Doxford J propulsion engines in production at present. This has a number of functions in addition to normal speed control; virtually no regular maintenance is required, and, in the rare event of trouble, diagnosis and rectification are simple and quick. A brief description of a small electric/electronic governor, with a torque output of 8 to 10 lb-ft (that of the type supplied for the Doxford is up to 400 lb-ft) and primarily designed for electricity-generating systems, is also included.
