Aqueous fuel emulsion identification system and anti-tampering device for an internal combustion engine

A fuel identification system for preventing the use of selected fuels in an internal combustion engine adapted to use an aqueous fuel emulsion, said fuel identification system comprising:

• a fuel delivery system for said engine, said fuel delivery system including a fuel tank and a fuel line in fluid communication with said fuel tank for supplying fuel to said engine;
• a fuel identification sensor disposed in operative association with said fuel delivery system and adapted to detect selected characteristics of a fuel in said fuel delivery system;
• a control unit responsive to said fuel identification sensor and adapted to differentiate between said aqueous fuel emulsion and other fuels to produce a signal that disables said engine when said other fuels are identified as being present within said fuel delivery system.

A method for preventing the use of other fuels in an internal combustion engine adapted to use an aqueous fuel emulsion, the method comprising the steps of:

• detecting selected characteristics of a fuel in a fuel delivery system of said engine;
• identifying said fuel in said fuel delivery system based on said detected characteristics;
• disabling said engine when one of said other fuels are identified as being present within said fuel delivery system.
