Abstract: Water from a tank is drawn upward by suction created by the vacuum in the carburetor air cleaner or in the engine intake manifold through a filter containing synthetic sponge material sandwiched between upper and lower layers of glass wool, where it passes through a heat exchanger coil which is heated by being positioned adjacent the exhaust manifold of an internal combustion engine. There it is vaporized into steam and then passes either through an inlet port into the base of the engine carburetor or directly into the intake manifold. The steam thus produced expands and mixes with and vaporizes the unvaporized droplets of gasoline in the gasoline vapor, breaking up these droplets into gasoline vapor before they can enter the intake manifold.

Abstract: A water induction system for internal combustion engines which consists of a metering device for metering controlled amounts of air and water, a control valve which is vacuum operated and connected to the metering device to allow a predetermined amount of air and water to be drawn into a heater wherein the air water mixture is vaporized and admixed with the fuel air mixture entering the intake manifold.

Abstract: Feed system for internal combustion engines to which is fed a fuel-air mixture and water vapor generated by a heat exchanger acted on by the exhaust gases, wherein there is a water chamber arranged before the heat exchanger in the water feed line, characterized in that the inlet and the outlet of the water chamber arranged directly before the heat exchanger are provided with valves which are to open automatically in an intrinsically known manner through the intake reduced pressure of the internal combustion engine and that the opening of the outlet valve is larger and/or longer in time than the opening of the inlet valve.INTRODUCTIONThe principle is already known of feeding water vapor to the combustion chamber of an internal combustion engine in addition to a fuel-air mixture, in order thereby to raise the power output and/or achieve a more economical fuel consumption, combined with a reduction in air-polluting components in the exhaust gases.

Abstract: Waste-gas suppressor for internal-combustion engines, utilizing negative pressure generated in the carburetor of the engine. A flow-regulator valve operated by the negative pressure adjusts water flow in proportion to engine speed, the water being evaporated by the exhaust heat of the engine. The resulting steam is supplied to the combustion chamber of the engine.

Abstract: An injector having a bore with an inlet and outlet therein and a vacuum responsive piston slidable within the bore. The piston carries a valve part which in conjunction with the inlet into the housing serves to regulate liquid flow being drawn from a reservoir through the housing and injected into the cylinders of the internal combustion engine in a manner responsive to the amount of vacuum created within the engine cylinders.

Abstract: Apparatus for feeding water to the air/fuel mixture passage between the air/fuel mixing device and combustion chamber of an internal combustion engine including a main conduit for supplying water to the mixture passage, a valve member for opening and closing the conduit, the valve member being biased into the closed position, a diaphragm communicating on one side directly to the mixture passage for actuating the valve member to an open position and on the other side through a pressure delay chamber with the mixture passage, wherein the conduit is opened only by a relatively abrupt increase in pressure in the mixture passage, and the closing is delayed until the pressure equalizes across the diaphragm. Water may be supplied to the conduit directly by a pump, or by a pressure differential or by means of a reservoir having access to a water supply.

Abstract: An improved device having no moving parts which, when in communication with the air intake of a carburetor of an internal combustion engine injects a mist of water into the air-fuel mixture formed by the carburetor, which water when in the zone of combustion in the engine reacts with carbon monoxide and free carbon therein to form carbon dioxide and hydrogen. The hydrogen so formed reacts with oxygen in the air-fuel mixture to form water that is either discharged in the exhaust from the engine or reacts with additional carbon dioxide and carbon in the zone of combustion to produce further carbon dioxide and hydrogen that continues until the carbon dioxide and water are discharged in the exhaust from the engine. The device when operating not only lowers the content of carbon monoxide in the exhaust discharged from the engine, but also tends to remove and minimize the depositing of carbon on spark plugs and in the cylinders of the engine.

Abstract: An apparatus for controlling and minimizing the production of the noxious exhaust gases from an automobile internal-combustion engine, comprising two passageways extending from an intake manifold provided with a throttle valve therein which is located between the two passage ways, one of the two passageways leading to a first control section provided with a diaphragm therein which is actuated in response to changes in the vacuum from the intake manifold for controlling the supply of water or like and air to the combustion chamber and the other leading to a second control section provided with a diaphragm therein which is actuated in the same manner for controlling the supply of part of the exhaust gases and air to the combustion chamber for reburning them, thereby enabling the supply of water or like, air and exhaust gases to be controlled according to the amount and type of the noxious exhaust gases.

Abstract: For introducing water in vapor form to the intake manifold of a combustion engine use is made of a double walled heat exchanger. Exhaust from the engine is passed through the space between an inner wall and an outer wall and then returned to the exhaust pipe. A chamber within the inner wall provides a reservoir of water and accommodates a float to control the level. For transporting vapors to the intake manifold of a combustion engine, a vacuum line from the intake manifold is in communication with the chamber at a location above the water level and induces air to flow through an air intake to a location adjacent the bottom of the water reservoir, releasing large bubbles of air below a dispersing plate through which a plurality of streams of small bubbles emerge bubbling to the surface, and entrain hot water vapor.
