| 41 | Method and apparatus for saturating a liquid fuel with a gas and an internal combustion engine | US271363 | 1981-06-08 | US4376423A | 1983-03-15 | Paul E. Knapstein |
| An apparatus and a method of saturating liquid fuel with air, oxygen, or another gas for injecting into an internal combustion engine. The internal combustion engine is provided with a gas compressor or pump for compressing air or oxygen, which is directed into a fuel saturator having a dense, porous material or stone therein and having a liquid hydrocarbon fuel being fed therethrough. Compressed gas is fed onto one side of the stone and is forced therethrough for saturation into the liquid fuel, which is then fed into a fuel injection system of an internal combustion engine. Gas that separates from the liquid fuel is trapped and vapor is removed therefrom. The fuel saturator uses a gas saturation stone, which may be hollow in one end for feeding a compressed gas thereinto, while the other side is surrounded with the liquid hydrocarbon fuel. The liquid hydrocarbon fuel may be fed around a spiralling passageway adjacent the stone for a more complete saturation of the fuel. | ||||||

| The opening of a solenoid valve is automatically adjusted after an engine is started and before actual work is performed for an appropriate air-fuel ratio, whereby it is possible to attain a good and stable driving of the engine without any delay even for an abrupt change in load. After the engine is started, when a rotation speed enters a “fuel flow rate adjusting rotation speed range” in which a definite load is applied to the engine in a working rotation speed range of the engine in which a throttle valve is opened to a definite opening, a detected rotation speed is fed back to a target rotation speed, and the opening of the solenoid valve is controlled to adjust a fuel flow rate, so that the combustion state in the engine is optimized at the valve opening so determined. | ||||||

| A needle is forced to open an injection hole by reducing a pressure of fuel in an injection control chamber to thereby inject fuel stored in a fuel storage, while the needle is forced to close the injection hole by increasing the pressure of fuel in the injection control chamber to thereby terminate injection of fuel from the injection hole. In a valve-closing stroke of the needle to close the injection hole, fuel pressure is supplied from a common accumulator to the fuel storage and the injection control chamber in such a manner that the pressure to supply fuel to the fuel storage is lower than that to supply fuel to the injection control chamber. In this way, a force acting on the needle toward the injection hole side can be increased in the valve-closing stroke, to thereby accelerate a valve-closing speed of the needle. | ||||||

| An electronic fuel injection system is combined with a carburetor in a carbureted internal combustion engine. The resulting air/fuel induction system comprises a carburetor air/fuel induction system in combination with an electronic fuel injection system which uses the carburetor of the carburetor system as the air valve for the electronic fuel injection system. The carburetor system and the electronic fuel injection systems are interconnected, preferably so that the mixture cut-off of the carburetor system is employed to shut off fuel flow in the carburetor to the air stream for the induction manifold and to simultaneously turn on the electronic fuel injector system. Either manual or automatic interconnection can be employed in the present invention. | ||||||

| A fuel controlling apparatus of an internal combustion engine for controlling a quantity of a fuel that is supplied to the engine includes: a fuel injector that injects the fuel to the engine, the fuel injector being controlled on a basis of a throttle opening degree and an engine speed without measuring a quantity of an intake air that is taken through an intake system of the engine; and a carburetor that supplies the fuel to the engine using a negative pressure produced by the intake system of the engine. The fuel is supplied to the engine solely by the fuel injector while the engine speed is lower than a lower limit of a high engine speed range including an upper limit engine speed. The fuel is supplied to the engine by both the fuel injector and the carburetor so that the fuel of a necessary quantity is supplied to the engine by combining a quantity of the fuel supplied by the fuel injector and a quantity of the fuel supplied by the carburetor while the engine speed is in the high engine speed range. | ||||||
| 57 | Stratifier apparatus for engines | US21627 | 1998-02-09 | US5899195A | 1999-05-04 | Joseph C. Firey |
| Engine stratifier apparatus is described, for use with piston internal combustion engines, to create stratified air fuel vapor mixtures within the engine combustion chamber. A fuel rich air fuel vapor mixture is created within a separate chamber, and then displaced into the engine combustion chamber, where it mixes with air and contained therein. The consequently leaner air fuel vapor mixture is spark ignited following mixing, and burning takes place. Very lean overall air fuel ratios can be used since a stratified mixture is created. Hence intake air throttling is unnecessary and thus engine efficiency is improved. The essential absence of liquid fuel during burning in the engine combustion chamber, largely prevents the formation of soot, and thus reduces undesirable exhaust smoke. | ||||||
| 58 | Venturi-assisted fuel injection carburetor system | US899342 | 1997-07-23 | US5809972A | 1998-09-22 | Barry Grant |
| Fuel at a regulated pressure passes from a fuel to tank one or more fuel injectors disposed in fuel injector housings formed in mounting blocks that are mounted to the sides of a carburetor center section. Each injector is in fluid communication with a booster venturi ring that is suspended in each carburetor barrel. The injectors intermittently deliver high pressure pulses of fuel to the booster venturi rings which disperse the fuel into the airstream. The high velocity of the airstream passing through the suspended booster venturi ring decreases the pressure of the airstream, resulting in greater atomization of the injected fuel. | ||||||

| Apparatus for injecting fuel into the intake pipes of an internal combustion engine. The apparatus has an air channel branching off from the intake line at a point ahead of an adjustable throttle flap; a fuel metering device supplying fuel to the air channel in dependence upon engine load; and a fuel delivery pump arranged to receive a fuel-air mixture from the air channel through a narrowed constriction. The fuel pump passes the fuel-air mixture, with additional air which may be supplied thereto, to a fuel distributor which directs the mixture to the individual intake pipes of the engine. | ||||||

| A fuel control device for a fuel injection system of a type having an intermittent injection type fuel injector disposed in a bore formed in the wall defining an intake passage. The device has a porous tubular element received in the bore in close contact with the fuel injector and defining therein a passage opened at its both ends.The fuel injected by the fuel injector is adhered to the inner surface of the passage defined in the porous tubular element. Air is introduced into the passage through fine air passages formed in the wall of the porous tubular element. The air introduced into the passage well atomizes the fuel into fine particles and is mixed therewith to form a homogeneous mixture. | ||||||
