Abstract:
The present invention achieves an increase in the amount of vapor that is expelled, stabilized fuel injection and improved starting characteristics in a fuel injection pump. In an electromagnetically driven fuel injection pump 20 which allows fuel to escape into the return passage 5 in the initial region of the pressure-feeding stroke of the plunger 21, and which pressure-feeds fuel into the injection port 33 in the later region of the pressure-feeding stroke, pulse powering of the coil 23 that does not lead to the injection of fuel, i.e., pulse powering which is such that the plunger 21 performs a reciprocating motion through the initial region, is performed when the engine 2 is in an idle operating state, or in a state in which the engine 2 is re-started after being stopped immediately following high-load operation. As a result, vapor can be expelled with good efficiency, and the flow rate of the circulated fuel is increased so that the cooling effect is also increased, thus causing the generation of vapor to be suppressed as well, so that the starting characteristics or re-starting characteristics are improved.

Abstract:
A slide and pin type carburetor using a plate-shaped slide valve in which the lower end surface of a flat plate portion is placed on the same plane as that of a column-shaped portion, the flow rate of air is controlled in the periphery of the column-shaped portion within the region in which the column-shaped portion exists and in front of the flat plate portion within the region in which no column-shaped portion exists, and a cutaway is formed, ranging from the surface located on the upstream side of the lower end of the flat plate portion to the bottom surface of the column-shaped portion, toward the downstream side, in order to make it possible to set properly the level of a negative pressure to be produced without raising abnormally the negative pressure produced in the vicinity of the exit of a main fuel nozzle and to increase the flow velocity of air, without producing any turbulence, in the vicinity of the exit of the main fuel nozzle so that the atomization of the fuel is favorably performed. The cutaway has an inclined surface descending from the upstream side toward the downstream side to shape a part of a conical surface directed to a fuel metering needle mounted on the bottom surface of the column-shaped portion.
Abstract:
The present device is a fuel supply device to pressurize and supply fuel F which is stored in a fuel tank 10, which comprises a fuel supply pipe 11 which forms a supply passage for the fuel F, a fuel filter 12 to filter the fuel F disposed at the midway of the fuel pipe 11 and below the fuel tank 10, a fuel pump 13 to pressure-feed the fuel F disposed at the downstream side than the fuel filter 12, and a venting pipe 15 to connect the downstream side of the fuel filter 12 and an upper air-space A of the fuel tank 10. The object is to provide the fuel supply device and the fuel filter utilized for the fuel supply device which can ensure the discharging amount of the fuel pump by satisfactory removing of vapor which is generated in the fuel sucked to the fuel pump.
Abstract:
An electronically controlled fuel injection device includes a plunger pump constituted by a cylinder, a plunger is slidably mounted within the cylinder to form a pressure chamber, and a solenoid coil for driving the plunger. At a lower section of a body that encases the plunger pump, an intake section is coupled to the pressure chamber to cause intake of fuel into the pressure chamber upon operation of the plunger. At an upper section of the body, a return section is arranged to return surplus fuel to a fuel tank. A circulation passage branches off from the intake section and is provided between the cylinder and the solenoid coil for guiding a portion of the fuel toward the return section. With this arrangement, penetration of vapor into the fuel injection device is suppressed, and an inexpensive and highly durable electronically controlled fuel injection device is provided.

Abstract:
With structure comprising a cylinder, a magnetic circuit to exert a mountain-shaped thrust, and a feeding spring to exert an urging force to a plunger during a feeding process, fuel is sucked by movement of the plunger and energy is accumulated in the feeding spring during a powering state, the fuel is fed by movement of the plunger by the urging force of the feeding spring during a non-powering state, a spring constant of the feeding spring is set to generate an urging force larger than a thrust in an early range of the mountain-shaped thrust, and a second spring is disposed to exert an urging force in a direction against the urging force of the feeding spring to make the urging force smaller than the thrust, at least in the early range. In this manner, with an electromagnetically driven type plunger pump of a non-powering feeding type, an effective stroke is enlarged and a feeding amount is increased.
Abstract:
An electronically controlled fuel injection device includes a plunger pump, a circulation passage which circulates fuel that has been pressurized in the initial stage of a pressure-feeding stroke, a valve body which blocks the circulation passage in the later stage of the pressure-feeding stroke, an inlet orifice nozzle which allows the passage of fuel whose pressure has been increased in the later stage of the pressure-feeding stroke, an outlet orifice nozzle which is used to circulate some of the fuel that has passed through the inlet orifice nozzle back into the fuel tank, an injection nozzle which injects an amount of fuel equal to the difference between the fuel that has passed through the inlet orifice nozzle and the fuel that has passed through the outlet orifice nozzle, and a control arrangement for controlling the plunger pump in response to the cycle of the engine.
