ABSTRACT:
Water is pumped from a holding tank through nozzle means to an area above the carburetion means on an internal combustion engine. The pumping means is controlled by diaphragm means reacting to intake manifold pressure as well as manual control. Filtering means are provided to allow the use of normal tap water. The diaphragm control means operates only after intake manifold pressure has risen to a certain point and ceases to operate after it has arisen above a second point or pressure. In another version, a variable pump is used to provide water in direct relationship to the manifold pressure over the indicated or selected range. The nozzle and the carburetion means act together to provide proper atomization of the water in the fuel air mixture.
