System and method for superheated-water injection system (SWIS)

Claim 1

The design and system for a superheated-water injection system (SWIS) which superheats water under pressure conditions to temperatures above 212° F. (100° C.) while preventing it from boiling, and injects such superheated water into the engine combustion chamber some micro- or milli-seconds after the point of ignition thus flashing the injected superheated water into superheated steam and generating a usable workforce incremental to and separate from that produced by combusting the fuel itself, the principal components of such superheated water injection system consisting of: (a) a water reservoir, (b) a water line, (c) a high-pressure, high-temperature water pump powered either by a motor or from a power take-off run by the engine, such pump being designed both to move water from the reservoir through the whole circuit and to build up and maintain pressure on the water contained in the line in excess of that existing at any time within the combustion chamber of the engine to which the SWIS device is intended to be attached, so as to prevent the water, though superheated, from flashing into steam until it is finally injected into the combustion chamber; (d) an accumulator to maintain water pressure in the circuit at the desired level at all times; (e) a water bypass system equipped with pressure-control valves to prevent water pressure inside the water line from building up beyond a designated maximum, (f) exchangers to transfer heat from the radiator water and/or the exhaust manifold gases and/or an electric heating device to the water passing through the water line; (g) a power unit connected directly to the engine combustion chamber and actuated by the engine's combustion gases a designed to force a timed and metered volume of superheated, pressurized water through the injector into the combustion chamber some micro- or milliseconds after the point of ignition, such power unti consisting of (i) a cylinder and a piston actuated by pressure from combustion gases; (ii) return springs positioned at the top and lower ends of the cylinder piston; (iii) check and pressure-central valves to prevent the contained water from being ejected or backing up until the desired pressure is brought to bear on the piston; (iv) a manually adjusted injection timing-control system consisting of an up-and-down screw installed at the top of the cylinder with a pointer and lock-in device; (v) an automatic injection timing-control system actuated by a hydraulic pump powered from the main engine by belt, gear or any means direct power takeoff and connected to the power piston by a pipe, check valves and pressure relief system designed to maintain a desired pressure directly proportional to the engine speed that is brought to bear on the upper return spring that the distance travelled by piston; and (h) an injector, turned and actuated by the power piston positioned to discharge superheated water into the engine combustion chamber.
