Abstract

A gas-diesel dual fuel engine operative with both a gaseous fuel and a diesel fuel oil. The engine has an electronic governor circuit adapted to receive both a speed signal representing actual speed of engine and a set speed signal representing a predetermined command speed of the engine, electric actuators adapted to actuate a diesel fuel injection pump and a gaseous fuel regulating valve, respectively, in response to the signal from the electronic governor circuit, and a mode switching control circuit connected to the electronic governor circuit and adapted to switch the operation of the electric actuators between a diesel fuel operation mode and a gaseous fuel operation mode.
