Abstract: An accelerated fuel passage of an accelerator pump operatively connected with a throttle shaft having a throttle valve. The accelerated fuel passage is connected to an upstream side of a needle orifice, which orifice is coupled to a main nozzle. Consequently, the fuel is discharged by the accelerator pump into an area before the needle orifice. By the addition of a one-way check valve system in a fuel pick up at a metering chamber for a fuel circuit, the fuel driven by the accelerator pump piston is discharged to a venturi tube of an intake passage through the main nozzle. A self pumping effect caused by an engine pulsation is dampened or eliminated by the needle orifice. Further, a check valve is provided within a fuel pick up at a metering chamber for a fuel circuit, whereby the fuel driven by the accelerator pump piston is discharged to a venturi tube through a main nozzle without returning to the fixed fuel chamber.

Abstract: The accelerator apparatus prevents air from remaining within a pump chamber and discharged fuel vapor from causing a pumping effect so as to a destabilize engine operation and increase of an exhaust gas content of harmful material, in an accelerator apparatus in which an accelerated fuel passage draws and discharges fuel to the pump chamber of an accelerator pump, which is connected to a main fuel passage. The pump chamber of the accelerator pump is mechanically coupled with a throttle valve and is connected to a fixed fuel chamber storing a fuel delivered to an intake passage at a fixed pressure by the accelerated fuel passage. Air remaining within the pump chamber and a fuel vapor generated within the pump chamber are discharged to the fixed fuel chamber, and fuel extruded from the pump chamber due to a pumping effect of the remaining air and the fuel vapor enters into the fixed fuel chamber, thereby preventing the alteration of a rate of the fuel flowing through a main fuel passage. Fuel in the pump chamber is fed to the fixed fuel chamber during acceleration so as to increase a pressure in the fixed fuel chamber, and an accelerated fuel is obtained by increasing the amount of the delivered fuel to the intake passage.

A vacuum actuated acceleration fuel pump is preferably carried by the float bowl and has a hose-less vacuum channel communicating between the fuel-and-air mixing passage downstream of a throttle valve and a vacuum chamber of the acceleration pump. A hose-less fuel discharge channel communicates between a supplemental fuel chamber of the acceleration pump and the fuel-and-air mixing passage between a venturi and a choke valve in the mixing passage. Preferably, the fuel discharge channel has an injecting bore portion defined by the body and being angled to direct fuel in a downstream direction toward the venturi to promote mixing with air.

Abstract: An accelerator pump cap for an accelerator pump assembly of a carburetor, such as a motorcycle or ATV carburetor, has a cap body with a base and a sidewall projecting from the base defining a fuel chamber within the cap body beneath an open top. Preferably, one or more ports extend through the sidewall closely-spaced to the open top of the cap body to ensure that any vapor or gas residing within the fuel chamber is flushed out of the fuel chamber through the port or ports when the accelerator pump assembly is actuated to supply fuel to the carburetor. Accelerator pump assemblies and the use of a separate collector ring within an accelerator pump cap are also provided.

Abstract: A system with which a correction of the fuel composition upon a change in the state of load of an internal combustion engine with which a mixture-forming device (4, 6, 8, 9, 11) is associated is constructed in structurally simple manner. The mixture-forming device has a feed unit (6) for the fuel with an inlet-side fuel conveyor line (5) and a discharge-side fuel conveyor line (7) and a movably mounted feed member (18). Depending on the position of the feed member (18), the feed member (18) provides variable fuel passage cross-sections in the feed unit (6). The feed unit is connected via an opening (31) which is closed in sealing fashion by a movable equalization element (33), the equalization space (32) being connected via a branch line (34) to the discharge-side fuel conveyor line. The feed member and the equalization element are coupled with each other locked for movement in such a manner that a movement of the feed member in the direction of an enlarged fuel passage cross-section leads to a movement of the equalization element which reduces the equalization space. A movement of the feed member in the direction of a reduced fuel passage cross-section leads to a movement of the equalization element which enlarges the equalization space.

Abstract: Several embodiments of accelerating fuel systems and methods for delivering accelerating fuel to an internal combustion engine over an extended time period. In each embodiment, the accelerating pump delivers a portion of its discharge fuel to a storage chamber and the storage chamber redelivers the fuel to the engine after the completion of the pumping stroke of the accelerating pump. In some embodiments of the invention, the stored fuel is returned to the engine by gravity. In some embodiments, the stored fuel is delivered to the engine at a different rate than the rate at which it is stored. In some embodiments, the return rate is dependent upon the change of speed of the engine and in other embodiments, the return rate is responsive to the acceleration of the vehicle powered to the engine.
