| PURPOSE:To prevent a decrease of flow speed of fuel fed from a low pressure fuel injection valve, by changing area of an orifice in the upstream of a throttle valve bypass passage at high load operation in accordance with a decrease of intake negative pressure. CONSTITUTION:A solenoid valve 16, varying air orifice area, is provided to an air orifice 15 in the inlet of a bypass passage 12, and an electric signal from an intake negative pressure sensor 17, detecting intake negative pressure in an intake pipe 7, is input to a solenoid valve control circuit 18, then fully or partially of fuel in lines of low speed, acceleration, starting and output is fed by a low pressure fuel injection valve 11 to arrange the amount, added with a feed amount of the main fuel system, equal to a required fuel amount of an engine. For negative pressure in the intake pipe at higher negative pressure side from pressure in a certain value P, the solenoid valve 16 is controlled to be fully opened, then in a range of 10 mode acceleration operation, delivery pressure of the fuel injection valve can be held to constant. | ||||||

| PURPOSE: To improve control accuracy through a simple construction, by setting an air fuel ratio of the main fuel system at a relatively smaller valve than a desired ratio and increasing the quantity of fuel through an auxiliary fuel feed valve, which controls the fuel of a slow system and a starting system etc., to attain the desired air fuel ratio. CONSTITUTION: Various signals S 1WS 9 corresponding to the driving variables of an engine are input into a digital calculation and processing unit 10 to determine the load on the engine. A target air fuel ratio for the control is set depending on the determined load. A mixture with a fixed air fuel ratio thinner than the target ratio is supplied through a main fuel feed means comprising a float chamber 33, a main jet portion 34 and a main air bleeder 35. Fuel, and the amount of the fuel supplied according to an instruction signal C 1 is supplied through an auxiliary fuel feed means comprising an auxiliary fuel feed valve 27 and an electromagnetic pump 28 in addition to said mixture supplied from the main fuel feed system, to attain the target air fuel ratio for the control.

| PURPOSE: To make the minute particles of fuel uniformly strike the whole throttle valve to make the distribution of mixed air uniform by providing the suction piston of which end surface projects into the suction passage and the pipe to conduct injection fuel at the position facing the projected end surface. CONSTITUTION: The suction piston 8 which is slidably guided and held in the guiding port 9 formed in the carburetor body 1 is moved rightward and leftward by the pressure difference between the negative pressure chamber 11 and the atmospheric pressure chamber 12 to maintain the flow speed of the suction air in the venturi part 21 almost constant. The pipe member 23 is burried inside of the carburetor body 1 so that it's top 24 opens at the venturi part 21 of the suction passage 2 at the position corresponding to the projected end surface 19 of the suction piston 8. Then, the nozzle end part 26 of the fuel injection valve 22 is connected to the other end 25 of the pipe member 23. The center line 27 of the pipe member 23, here, is provided to be at a right angle to the direction of the air flow in the venturi part 21. COPYRIGHT: (C)1980,JPO&Japio | ||||||

| PURPOSE: To obtain uniform mixture gas for stabilizing idling operation by atomizing with air current the fuel having attached to the inner face of a hollow, porous conduit placed in the vicinity of a fuel jet valve. CONSTITUTION: The lower-course portion of a suction passage 12 is divided in primary and secondary passages 14 and 16 by a partition wall 62, and a fuel jet valve 22 is attached to a body 10 on primary passage 14 side. A porous conduit 32 is provided in the vicinity of the discharge hole of the fuel jet valve 22, and jet fuel is supplied to the lower-course side of the primary passage 14 than a throttle valve 18 through the conduit 32. The conduit 32 is fitted on a fitting hole 36 via an O-ring 40. An air chamber 42 therefore formed between the conduit 32 and the wall of the hole 36 communicates to a suction passage 12 via an air passage 34. Thereby the fuel jetted through the jet valve 22 is let attach to the inner face of the conduit, atomized by the air current from the air chamber 42, and led to a mixture gas passage 44.

| 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. | ||||||

| 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. | ||||||
