Abstract
A method for controlling fuel flow to apportion a plurality of available fuels in a multi fuel engine is disclosed. An input power for operating the multi fuel engine at a desired engine speed is determined at a PI controller, and a fuel flow rate for each of a plurality of available fuels is determined at a fuel apportionment module based on the required input power and a specified fuel substitution ratio for apportioning the plurality of fuels to the multi fuel engine. Fuel flow commands for each of the plurality of fuels are output to corresponding actuators of fluid flow control devices for the fuels to cause the cause the fluid flow control devices to provide the corresponding fuels to the multi fuel engine at the corresponding fuel flow rate.
