ABSTRACT:
A dual fuel control system (10) for use with an internal combustion engine (11) is disclosed which controls the flow of liquid fuel alone or in combination with a gaseous fuel. The system has a stored supply of gaseous fuel and a fuel metering actuator (22) which regulates the flow of the gaseous fuel to the engine. The system also has a stored supply of liquid fuel and a fuel control actuator (47) which regulates the flow of diesel fuel through the movement of the shutoff valve (31) of a diesel fuel pump (28). A controller (45) controls the actuation of the actuators in response to signals received from an accelerator sensor (37), an R.P.M. sensor (45) and an exhaust temperature sensor (41).
