1. A method for controlling operation of an internal combustion engine configured to run on a fuel mixture of hydrogen and natural gas, the method comprising:
obtaining temperature values measured by at least one temperature sensor provided in a cylinder head of the engine, the temperature values correspond to a composition of the fuel mixture, the fuel mixture is provided before entering a combustion chamber;
determining a composition of the fuel mixture based on the obtained temperature values and a reference temperature, the composition indicative of a portion of hydrogen in the fuel mixture; and
controlling operation of the engine based at least in part upon the composition of the fuel mixture.
