Abstract
The disclosure relates to a system and method for determining the specific gravity of a fuel used in a dual fuel engine. The system includes a fuel rail, at least one sensor, and a processor. The method includes sensing and recording, with the at least one sensor and the at least one memory, a first pressure profile of a first fuel in the fuel rail and a second pressure profile of a second fuel in the fuel rail. The first fuel has a known specific gravity and the second fuel has an unknown specific gravity. The method further includes calculating the second specific gravity of the second fuel, with a processor, based on the first pressure profile, the second pressure profile, and the first specific gravity.
