  • Patent number: 5931123
    Abstract: Fuel injector apparatus is described, for use on internal combustion engines using slurry fuels, wherein a portion of the engine air mass is passed through an aspirator passage shortly prior to combustion and the slurry fuel is aspirated into this air portion. The thusly mixed air and fuel slurry is distributed throughout the engine combustion chamber via several exit channels from the aspirator. The fuel portion of the slurry is reduced to a very small size when the slurry is prepared, and fine atomization of the slurry during injection into the engine is not needed. Hence relatively low velocity slurry injection can be used and injector wear problems greatly reduced.

  • Patent number: 4541383
    Abstract: The invention relates to method of, and apparatus for, operating an internal combustion engine on low knock-rated fuels as the primary fuel system in which engine knock is anticipated and suppressed by simultaneously detecting actual engine load conditions that may induce such knock and knock condition that actually are occurring in at least one combustion chamber of the engine. In response to such simultaneous conditions, a small but effective amount of anti-knock fluid is supplied to the engine combustion chambers in an amount and for a time sufficient only to suppress knock to a satisfactory level. Such a system permits the use of more economic fuels, such as gasoline, having a substantially lower knock rating than those normally used in automotive equipment and only small but sufficient anti-knock fluid is added solely when the engine is knocking.

    Abstract: The present moisturizer for air going into a combustion process has a venturi passageway through a liquid permeable, porous, open-ended, annular body surrounded by liquid such as water and a valve in the venturi passageway. The valve is spring-biased toward the air inlet end of the venturi passageway to provide a maximum flow restriction at low volume demand. The valve deflects air outward against the inside wall of the porous body which defines the venturi passageway for the purpose of enhancing the withdrawal of moisture from the porous body, particularly at low volume demands. At progressively higher volume demands, the valve is displaced by the air toward the air outlet end of the venturi passageway to enlarge the effective open area of the passageway around the valve. Preferably, the valve operates to keep the air velocity through the venturi passageway substantially constant at different air flow demands.

  • Patent number: 4368711
    Abstract: A water-augmented fuel and air supply system for an internal combustion engine which draws heated air into its intake manifold through two paths, one carrying the bulk of air, referred to as leaning air, drawn directly into the manifold, and the other providing a smaller stream of mixing air through a fuel and water vaporizer heated by engine exhaust. In the vaporizer, the heated mixing air flow acts upon a pool of liquid water and fuel to stimulate vaporization thereof. As engine temperature and engine exhaust temperature rise, the maximum vaporization stimulation effect of the impinging mixing air is no longer needed and is correspondingly reduced. The result is to permit cold starts and to provide a lean mixture of vaporous mixing air conducive to sustained economical engine operation, and increased power availability from the engine without incurring excessive rise in engine operating temperatures.

  • Patent number: 4306519
    Abstract: A vaporizer cooperating with a recirculating water system humidifies air before it enters the carburetor of an automobile engine. The vaporizer is generally a hollow tube which includes an evaporating pad that distributes liquid such as water. As air moves through the vaporizer, vapor moves into the air stream. Excess liquid is collected at the bottom of a larger portion of the vaporizer, whose air outlet is elevated from that bottom to prevent liquid phase water from leaving the vaporizer. The recirculating system drains collected excess water.

  • Patent number: 4300485
    Abstract: A fluid injection system for an internal combustion engine such as spark-ignition engine in which an injection nozzle injects a finely divided spray of fluid, such as water or a water solution, into the engine in response to a flow of atomizing air. The nozzle is connected to a fluid supply reservoir and to the outlet line of an air-injection pump that is connected to an electronic control circuit which includes an inductive pick-up coupled to the ignition system of the engine and a pressure responsive sensor that is coupled to the intake manifold. The electronic circuit thus operates the pump in response to engine speed by virtue of its connection to the ignition system through the inductive pick-up and in response to engine load by virtue of its connection to the intake manifold through the pressure responsive sensor. As a result, the flow of atomizing air to the nozzle and therefore the rate and magnitude of water injection is responsive to engine speed and engine load.

  • Patent number: 4300484
    Abstract: A fluid injection system for an internal combustion engine such as a spark-ignition or compression-ignition engine in which an injection nozzle injects a finely divided spray of fluid, such as water or a water solution, into the engine in response to a flow of atomizing air. The nozzle is connected to a fluid supply reservoir and to the outlet line of an air-injection pump connected to and controlled by an electronic circuit that includes a pick-up coupled to the ignition system of the engine. The electronic circuit responds to spark plug firing rate, which is proportional to engine speed, and to the amplitude of the voltage across the spark plug gap, which is proportional to engine load, and varies, respectively, the pump stroke rate and the pump stroke length accordingly. As a result, the flow of atomizing air to the nozzle and therefore the rate and magnitude of water injection is responsive to engine speed and load.

  • Patent number: 4296723
    Abstract: The system includes a fuel storage tank connected to a vacuum pump by a supply line, a fuel/water separator, a fuel lift pump, a fuel/water return line and a fuel injector pump or carburetor. The fuel/water separator includes a coalescer interposed between the fuel lift pump and the injector pump or carburetor to separate the water from the fuel. Water collects in the lowest portion of the separator housing, is removed through an orifice in the fuel/water return line, and is routed back to the fuel tank. With moderate levels of water contamination in the fuel tank the system prevents water from reaching the fuel injector pump or carburetor for an indefinite period of time. The separator housing is constantly drained since the separator is under pressure. The system has a suitable detector to detect the water level in the fuel storage tank. Water may be removed from the fuel storage tank by temporarily converting a part of the water/fuel return line to a water outlet pumping line through a three-way valve.

  • Patent number: 4286550
    Abstract: A fuel additive injection device for injecting an additive into an automotive engine to slow down the burning rate of gasoline while the engine is under heavy load, thereby reducing knocking or pre-ignition while increasing engine output power and increasing fuel mileage. A vacuum chamber having a diaphragm therein is connected to the intake manifold of the engine so that the diaphragm moves back and forth as the pressure in the intake manifold changes. A connecting rod is coupled to the side of the diaphragm opposite to the interior of the chamber. A needle valve connected to the diaphragm through a control rod and a connecting rod and positioned through a valve seat in a flow control passage regulates the flow of additive into the intake manifold of the engine, preferably through the throat of the carburetor. When the pressure in the chamber increases corresponding to a heavy engine load, the needle valve opens increasing the flow of additive to the engine which in turn reduces the burning rate.

  • Patent number: 4279223
    Abstract: The present disclosure shows a system for providing a continuous supply of at least partly distilled water to an internal combustion engine for inclusion in the air-fuel mixture passing through the carburetor, in order to increase the efficiency of the engine to decrease fuel consumption, to reduce emissions and to prevent knocking. The water may be mixed and emulsified with the liquid fuel before these components enter the carburetor, or the fuel may be introduced to the carburetor separately, or the water and the fuel may be introduced together without a preliminary mixing. The partially distilled water, that is free of solid ingredients, is produced continuously during engine operation by diverting a portion of the exhaust gas from the engine to an air cooled condenser to condense water therefrom and a controlled amount of water is passed to the engine. Means are provided for variably proportioning the quantity of water delivered to the quantity of liquid fuel passing to the carburetor.

  • Patent number: 4237826
    Abstract: A multi-cylinder internal combustion engine having a plurality of cylinders, each comprising a combustion chamber and an accumulation chamber which are interconnected to each other via an accumulation valve. The accumulation chambers are interconnected to each other via a common connecting passage. The opening operation of the accumulation valve is controlled so that the accumulation valve remains opened during the compression stroke. In the first half of the compression stroke, a jet of the combustible mixture is spouted out into the combustion chamber from the accumulation chamber to create a strong swirl motion in the combustion chamber. In the latter half of the compression stroke, the combustible mixture in the combustion chamber flows into the accumulation chamber to accumulate the combustible mixture under high pressure, which is spouted out into the combustion chamber at the next cycle.

  • Patent number: 4231333
    Abstract: This invention relates to a computer controlled fuel system for an internal combustion engine including a low profile carburetor for permitting engine operation on very lean fuel/air ratios without sacrificing engine performance during critical engine operations such as start up, warm-up and acceleration. The low profile carburetor provides a single point source fuel dispersion and includes one or more throttle controlled, sliding plates for increasing fuel entrainment at low engine speeds by increasing the velocity of the airstream flow through the carburetor just before the dispersion point and by maximizing the lateral distance between the point of fuel dispersion and the carburetor airstream. The computer controlled system includes various threshold circuits for providing additional fuel and/or water injection into the carburetor airstream upon detection of predetermined engine conditions.

  • Patent number: 4173450
    Abstract: Combustion efficiency in an oil burning furnace is increased by the catalization effect of consuming atmospheric air processed to increase its humidity. Atmospheric air is processed by either forcing air into a water container and bubbling it through water by a drawing, natural draft type of action through the container; or atomizing the air. Three embodiments of my invention are disclosed whereby the processed air is conveyed directly into the combustion zone, into an oil gun of an oil burning furnace or both directly into the combustion zone and the oil gun. A further increase in thermal efficiency is achieved by adding ozone to the processed air. By use of a proper nozzle, processed air is directed at the base of the flame within the furnace in substantially the same shape and direction as the flame when employed in the embodiment injecting said air directly into the combustion zone.
