Claim:
1. A method for controlling fuel flow in a multi fuel engine, comprising: determining an input power for operating the multi fuel engine at a desired engine speed; determining a fuel flow rate for each of a plurality of fuels that are available for providing power to the multi fuel engine based on the input power, one or more fuel properties of a pre-determined fuel type, and a specified fuel substitution ratio for apportioning the plurality of fuels to the multi fuel engine; determining a correction factor for the fuel flow rate based on a desired charge density, wherein the desired charge density is based at least on a relationship between an engine load and a calculated charge density of the multi fuel engine; and outputting a corrected fuel flow rate, based on the determined correction factor, for each of the plurality of fuels to a corresponding actuator of a fluid flow control device for the one of the plurality of fuels to cause the corresponding actuator to provide the one of the plurality of fuels to the multi fuel engine at the corrected fuel flow rate.
