Abstract
A system and method for the identification of the fuel being transported within a fuel delivery system of an internal combustion engine that may utilize an advanced fuel such as a fuel in water emulsion is provided. The identification of the fuel is accomplished using a fuel identification sensor that distinguishes the fuel type based on differences in optical properties, electrical properties, physical properties, or other characteristics between an aqueous fuel emulsion and a conventional fuel. The disclosed fuel identification device is readily incorporated in an anti-tampering device for preventing the use of a conventional fuel, such as diesel fuel, in an engine designed and certified for aqueous fuel emulsions.
