ABSTRACT:
A method and system for the control of the overall water content of an aqueous fuel in an internal combustion engine is provided. The disclosed fuel control system includes a post add water system and a control valve that is responsive to selected engine operating characteristics such as engine operating temperature, engine load, and carbon monoxide levels in the engine exhaust. The post add water system is adapted for selectively providing an additional supply of purified water via the control valve to the aqueous fuel in the fuel line. The fuel system controller is operatively associated with the control valve to regulate the quantity of water added and thereby control the overall content of water in the aqueous fuel emulsion delivered to the fuel injectors.
