  "textContent": "A method for determining a fuel characteristic, the method including receiving a gaseous fuel within a gaseous fuel rail of a dual fuel engine configured to run on at least the gaseous fuel and a diesel fuel. The method may include receiving a pressure signal from a pressure sensor indicating a pressure of the gaseous fuel within the gaseous fuel rail, and identifying at least one of an amplitude and a phase of the pressure signal, The method may further include determining a characteristic of the fuel within the fuel rail based on the amplitude or the phase of the pressure signal, and, based on the determined characteristic of the fuel, modifying an operational parameter of the dual fuel engine.",
