| 21 | Fuel injector with air bubble/fuel dispersion prior to injection and method of operation | EP97112220.5 | 1997-07-17 | EP0821159A3 | 1998-02-04 | Pace, Jeffrey B.; Warner, Vernon R. |
A fuel injector for an engine includes a fuel volume (24) having an air inlet port (30) having a porous membrane (38). The membrane (38) is permeable to air and impermeable to fuel whereby air inlet to the fuel volume (24) forms a two-phase air bubble/fuel dispersion within the fuel volume (24). Upon actuation of the needle valve (18) of the injector, this two-phase air bubble/fuel dispersion flows through the orifice (28) into the engine whereby improved atomization, burn and fuel economy with resultant reduction in emissions are provided. |

The fuel and air supply system of the present invention provides fuel from a fuel pump (42) at a first pressure upstream of a pressure reducer (46), fuel being provided directly to the fuel injector (10) at a reduced pressure on the downstream side of the pressure reducer (46). A bypass line (34) in communication with the fuel line (44) upstream of the pressure reducer (46) provides fuel to an air reservoir (50) at the first pressure. The air reservoir (50) lies in communication with a porous member(s) (30) in the fuel injector (10) in an air inlet (32) to a fuel volume (24) within the injector (10). Upon flow of fuel into the air reservoir (50) and closure of normally open fuel and air valves (58,60) in the reservoir (50), air at the first pressure is supplied the porous member(s) (30), creating a pressure differential across the member(s) (30), causing air to flow through the porous member(s) (30) to form air bubbles in the fuel volume (24) for two-phase flow through the fuel injector orifice (28). The air flows for a predetermined time until the reservoir (50) fills with fuel which precludes further air flow into the injector (10). Upon shutdown of the engine, the valves (58,60) in the air reservoir (50) open, draining the fuel from the air reservoir (50) and enabling air at atmospheric pressure to enter the reservoir (50), returning the system for reuse upon engine startup. |

| PURPOSE:To improve fuel response characteristics by making an air diluting leak orifice opened in the direction of introducing dynamic pressure upstream of a throttle valve, in a fuel discharge portion between a sonic orifice and the leak orifice. CONSTITUTION:A mixture from a main jet 8 and a main air bleeder 9, and a mixture passing through an injector 15 and a sonic orifice 11 serve as supply source in the intermediate speed range, while a mixture is supplied from a small venturi 3 and the injector 15 in the ratio of 2:1 in the heavy load range. Further, a leak orifice upstream of a throttle valve increases the flowing velocity of a fuel discharge portion 14 the more as the lower vacuum pressure is, since the leak orifice has an opening 12a directed to the upstream side of an intake air pipe 1, thereby the distributing characteristics and as well the response of fuel atomization are improved. Further, the selection of pressure level upon heavy load state or low negative pressure state may be made by suitably selecting both orifices 11, 12. | ||||||

| PURPOSE: To feed an adequate amount of fuel to an automobile engine in its wide range operational state through the above described device, by connecting the return flow line of a fuel pressure regulator to the richer nozzle passage of a throttle main unit and opening a valve at high loaded operation of the engine at its high speed. CONSTITUTION: A fuel pressure regulator 12 is provided with a seat part on the upper side of a diaphragm supported by a coil spring, when prescribed pressure fuel passes, the seat part is sealed by a seat, however when high pressure fuel is fed from a pipe 11, the diaphragm is depressed to open the seat part, and a surplus amount of the fuel is released to a pipe 10. While in a throttle main unit 1, negative pressure is generated in a richer nozzle 8 as intake air quantity increases, and a check ball 5 is lifted by overcoming tension of a spring 6, then fuel from a pipe 4 is sucked and supplied from the pipe 10 of the fuel pressure regulator 12 through a fuel passage 14.

| PURPOSE: To atomize the fuel into fine particles and improve the distribution of fuel mixture among the cylinders at the feeding of fuel mixture being injected at a portion downstream of the throttle valve, by disposing an orifice for fuel injection in face of an orifice for injecting bleed air. CONSTITUTION: When such an amount of fuel as required by the internal combustion engine is ejected from injection valve 200, it is mixed with bleed air supplied from air bleed passage 104 and ejected from orifice 102 after it is atomized into fine particles in passing through sonic nozzle 203. Then, atomized fuel collides with bleed air supplied through air bleed passage 104' and accelerated at sonic nozzle 105, so that its horizontal velocity component becomes substantially zero. At the same time, atomized fuel is scattered in every direction in venturi 103 and drawn into the combustion chamber while being mixed with air fed through throttle valve 101. Thus, atomized fuel from sonic nozzle 203 is scattered in every direction by the bleed air from sonic nozzle 105 with its velocity being lowered by the bleed air, so that mixture can be distributed uniformly to a plurality of cylinders.

| A fuel delivery system for an internal combustion engine includes induction conduits of effectively equal flow resistance for guiding separate air and fuel streams to each of the cylinders of the engine. Each induction conduit includes at its entrance a sleeve venturi for inducing fuel into the air stream and a booster venturi. A fuel injector applies fuel at high pressure to the booster venturi. Flow modifiers may be positioned in the venturi throat and down stream of the venturi for modifying the flow of the stream of air after the fluid has been induced and injected into the stream of air for further subdividing the fuel vapor for increased effect of combustion of the fuel and air mixture. | ||||||

| A fuel controlling apparatus includes: a fuel injector, 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; 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. | ||||||
| 37 | Air fuel vapor stratifier | US986608 | 1997-12-08 | US5899188A | 1999-05-04 | Joseph C. Firey |
| An air fuel vapor 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 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 absence of liquid fuel during burning in the engine combustion chamber, largely prevents the formation of soot, and thus reduces undesirable exhaust smoke. | ||||||

| An air/fuel handling system for a small fuel injected engine with a preferably extruded body having an air tuning chamber, a fuel pump chamber and a fuel rail chamber therein for supplying fuel to one or more fuel injectors. A preferably separate fuel metering and throttle body is mounted on the chamber body. Air is supplied to an intake passage of the throttle assembly to the air chamber which has ram tubes for supplying combustion air to the intake manifold of the engine. Fuel from a remote gasoline tank is supplied through a metering valve assembly to the inlet of an electric fuel pump mounted in the pump chamber which supplies high pressure fuel to the fuel rail and injectors and thus to the engine. Fuel vapor in the metering chamber is separated from liquid fuel and supplied to the air intake chamber when the engine is operating. | ||||||

| A fuel supply system for mixture-compressing internal combustion engine with externally-supplied ignition is proposed, which serves to form the most optimal possible fuel-air mixture. The fuel supply system includes a primary mixture formation unit disposed in the intake manifold and at least one ultrasonic atomizer nozzle in the intake manifold, for the purpose of correcting the fuel-air mixture by means of supplementary fuel, downstream of the primary mixture unit or in each individual intake tube. The ultrasonic atomizer nozzles are triggered, with the interposition of an electronic control device, in accordance with operating characteristics of the engine, as well as the exhaust composition, and they permit the supply of finely prepared supplementary fuel for the purpose of regulating the fuel-air mixture to a predetermined .lambda. value; of compensating for non-uniform distribution, and of enrichment of the mixture in the case of warm-up, full load and acceleration, as well as of idling regulation. | ||||||
