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.

13 Fuel/air supply system for a fuel injector and methods of operation US686937 1996-07-26 US5666927A 1997-09-16 Jeffrey B. Pace; Vernon R. Warner
The fuel and air supply system of the present invention provides fuel from a fuel pump at a first pressure upstream of a pressure reducer, fuel being provided directly to the fuel injector at a reduced pressure on the downstream side of the pressure reducer. A bypass line in communication with the fuel line upstream of the pressure reducer provides fuel to an air reservoir at the first pressure. The air reservoir lies in communication with a porous member(s) in the fuel injector in an air inlet to a fuel volume within the injector upstream of the pressure reducer. Upon flow of fuel into the air reservoir and closure of normally open fuel and air valves in the reservoir, air at the first pressure is supplied the porous member(s), creating a pressure differential across the member(s), causing air to flow through the porous member(s) to form air bubbles in the fuel volume for two-phase flow through the fuel injector orifice. The air flows for a predetermined time until the reservoir fills with fuel which precludes further air flow into the injector. Upon shutdown of the engine, the valves in the air reservoir open, draining the fuel from the air reservoir and enabling air at atmospheric pressure to enter the reservoir, returning the system for reuse upon engine startup.
14 Cylinder injection type two cycle engine US558246 1990-07-24 US5138984A 1992-08-18 Kazutoshi Takashima
A fuel supply system for a two cycle crankcase compression internal combustion engine embodying direct cylinder injection and carburetors for supplying a fuel air mixture to the crankcase chambers of the engine for high speed cooling. The direct fuel injectors supply the fuel at the low speed operation and a fixed amount of fuel at mid range and high speed, while the carburetor supplies only the mid range and high speed requirements of the engine in combination with the fuel injectors. Fuel is supplied first to the fuel bowls of the carburetors which have a vapor vent and then from the fuel bowls to the fuel injectors so as to avoid the necessity of a separate vapor separator for the fuel injectors.

16 Auxiliary fuel supply system US59791 1987-06-09 US4777913A 1988-10-18 Richard E. Staerzl; Norman H. Radtke; Leonard S. Hummel
An auxiliary fuel supply system is provided for a two cycle internal combustion engine (302). A first fuel line (350) supplies fuel from the fuel pump (338) to a solenoid (352) which is continuously cyclable between ON and OFF states during running of the engine, includig high speed operation where detonation may occur. Fuel then flows through a second fuel line (354) to a restriction orifice metering housing (356), and then to a plurality of third branch fuel lines (358, 384, 386, 388, 390 and 392) for delivery to respective cylinders. The restriction orifices provide a pressure drop from the second fuel line to the plurality of third fuel lines, to provide lower fuel pressure in the third fuel lines, to reduce the chance of leakage at the intake manifold (326), and also to reduce fuel pressure fluctuations in the third fuel lines otherwise due to cycling of the solenoid. Metering housing structure is disclosed. The solenoid is controlled by a variable duty cycle oscillator (408), which in turn is controlled by a fuel enrichment signal (84) output by an electronic control which is responsive to engine knock and/or temperature. Control circuitry is disclosed.
17 Fuel injection system and method for internal combustion engine US834875 1977-09-20 US4157084A 1979-06-05 Marvin E. Wallis
An air and fuel mixing device incorporates a Venturi throat or other mixing means for feeding a highly combustible mixture of fuel and pressurized air to an electrical fuel injector valve or directly to the intake manifold in a system for starting an internal combustion engine. The system replaces the choke in a conventional electrical ignition type internal combustion engine. The fuel injector valve is controlled to inject a limited quantity of a highly combustible atomized air-fuel mixture into the engine intake manifold during engine startup. Startup is achieved with minimum fuel waste and produces a minimum of exhaust pollutants. A modified form of the invention is shown as employed in a fuel injection type internal combustion engine system wherein high pressure air-fuel mixture is fed to the fuel injectors solely through use of a conventional low pressure fuel pump and air supply. The injectors operate to discharge a highly volatile, combustible, air-fuel mixture under pressure, instead of raw fuel thus significantly increasing combustion efficiency during engine startup to minimize fuel waste and reduce deleterious exhaust emissions. Another modified form of the invention is shown wherein the system is employed to feed a mixture of fuel and pressurized air to the engine intake manifold in response to an acceleration command from the engine throttle control during normal engine operation. This eliminates the need for the notoriously troublesome carburetor accelerator pump now in conventional use.
