ABSTRACT:
A fuel control device for a combustion engine capable of running on any one of a plurality of fuels has a fuel selection module with a plurality of fuel type settings for selecting a specific fuel type whereupon the fuel control device controls the outlet pressure of the chosen fuel to a desired fuel pressure corresponding to the calorific properties of the chosen fuel. The fuel selection module preferably operates a plurality of fuel flow circuits each designated for a specific fuel type, and each having a biased closed inlet valve and a biased closed outlet valve. Located preferably between each inlet and outlet valve is a pressure regulator designated for the specific fuel type and controlling the outlet fuel pressure. The device preferably includes a fuel metering apparatus and a shutoff valve that communicate with, and control in part, fuel flow through the fuel flow circuits.
