ABSTRACT:
A compression ignition engine can be quickly and easily converted into a dual fuel engine simply by adding a gaseous fuel supply system, by disconnecting the governor actuating lever from the throttle pedal, and by adding an electronic controller which controls the operation of the gaseous fuel supply system and which sets the governor actuating lever at a position which causes the engine to deliver pilot fuel at a desired quantity. Operation is simplified by setting the governor using a droop control technique inherent in governor operation. The system can be automatically calibrated to assure the supply of fuel at a precisely controlled quantity per stroke at all engine speeds. The pilot fuel injection system of the resulting engine is non-invasive and permits inherent safety features of the governor to be retained.
