Classification: CPC F | IPC F

Claim 14:
15. A method of operating an internal combustion engine, comprising:
receiving a power signal indicating a desired power level of the internal combustion engine;
accessing a fuel map to calculate a default ratio of a second fuel to a first fuel and a flowrate of the first fuel and the second fuel, wherein the fuel map is a table indicating that for a power level, an amount of the first fuel and an amount of the second fuel for the power level;
calculating a concentration of water absorbed by the second fuel stored in a second fuel tank based on a water volume signal received from a water sensor;
modifying the default ratio, the flowrate of the first fuel, and the flowrate of the second fuel based on the concentration of the water in the second fuel;
outputting a mixing signal to modify a position of a mixing valve based on modifying the default ratio; and
outputting a first pump signal to change the flowrate of the first fuel pump and a second pump signal to change the flowrate of the second fuel pump based on modifying the flowrate of the second fuel and the first fuel based on the concentration of the water in the second fuel.
