Abstract: A flow rate control mechanism is provided to a low-speed fuel system that is independent from the main fuel system of a carburetor. The mechanism causes the valve element to move in a linear fashion by means of a cam coupled to the throttle stem. The mechanism increases the effective cross-sectional area of the low-speed fuel channel as the throttle valve opens from the idle position to the maximum degree of opening until the point in time at which the main fuel begins to flow, and thereafter causes the low-speed fuel flow rate to decrease and become zero in the high-output region. The transition from low-speed fuel to main fuel is made smooth, ensuring higher output and a stable fuel flow rate in the high-output region.

Abstract: A method for controlling an engine for a model and a device therefor capable of improving throttle response. Feed of fuel to the engine is increased during acceleration of the engine and decreased during deceleration thereof. This permits a rotational speed of the engine to be smoothly and rapidly varied, to thereby reduce vibration of the engine and prevent knocking and breathing of the engine. Also, adjustment of a trim provided on a side of a controller leads to adjustment of a needle valve, so that the adjustment may be facilitated.

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.

Abstract: A control system for a feedback carburetor in which a controlled vacuum is applied to the carburetor fuel bowl to reduce the fuel flow rate and provide maximum fuel economy. Engine speed is monitored and reduced a predetermined amount during steady state cruising through use of an air control solenoid to apply the controlled vacuum. The controlled vacuum is removed during acceleration or when engine speed is outside the range of steady state cruise speed.

Abstract: In order to produce a transition mixture enrichment during acceleration of an internal combustion engine, a carburettor or other mixture generator 1 of the engine with a mixing chamber 2, a main throttle 4 and a choke valve 5, has the choke valve 5 operated by a quick-acting electric drive 6, for example a two-coil rotary setter, which is controlled by a microprocessor 8. The microprocessor is fed with signals which sense the opening of the main throttle 4 and preferably also other engine operating parameters such as temperature and speed. When the main throttle 4 is opened to accelerate the engine, the microprocessor 8 causes the electric drive 6 to close the choke valve 5 abruptly and temporarily. The extent of closure of the choke valve 5 is dependent upon the extent of the throttle opening and on the other operating parameters to give the required mixture enrichment. This arrangement avoids the necessity to provide an accelerator pump.

Abstract: A carburetor for supplying the mixture of optimum air-fuel ratio to the engine at all times under any accelerating condition. The carburetor comprises a fuel adding valve and associated valve mechanism whereby when the vacuum pressure in the suction pipe decreases as a result of acceleration, the fuel adding valve is opened to deliver extra fuel in addition to the main fuel to produce the mixture of optimum richness. With this invention, the conventional drawback can be precluded that after the first stage of acceleration the mixture becomes leaner than is required.

Abstract: An i.c. engine fuel system uses a conventional carburettor modified by the addition of an air pressure control to the float chamber thereof. The air pressure control includes a bank of valves connected in parallel to exhaust a chamber connected by an orifice to the engine intake manifold. The chamber is connected to the float chamber and the valves are controlled by the individual bits of a digital output signal produced by a digital read only memory addressed by digital signals corresponding to two engine parameters such as engine speed and throttle angle.

Abstract: A compensation apparatus for a carburetor having a first opening in the wall of the air intake passage near the edge of the throttle valve so that the first opening is positioned upstream or downstream of the throttle valve depending on the degree of opening thereof. A second opening is similarly provided in the wall of the air intake passage so that it is positioned downstream of the throttle valve, at least when the first opening is positioned upstream thereof. A connecting passage joins the first and second openings, and a further passage supplies fuel to the connecting passage. Air is reversely bled through the first opening and fuel is discharged through the second opening, whereby fuel shortage due to response delay in the transitional region between the low-speed and high-speed phases, or in the transitional region between the idling and the low-speed phases, is prevented.
