摘要： Method, system and apparatus for metering fuel to an internal combustion engine via a carburetor having a mixture conduit with a venturi therein. A main fuel nozzle supplies fuel to the venturi of the carburetor in response to the static pressure drop induced across an associated main fuel flow controlling restriction by the engine intake induced air flow through the carburetor mixture conduit. A pitot tube is disposed in the venturi with an opening facing upstream in a zone of maximum air flow through the carburetor venturi. A vent passageway system connects the pitot tube to a single closed air chamber cooperable with either a diaphragm or a float to regulate operation of an inlet valve controlling flow of fuel to a main fuel controlling restriction. The adverse effect of engine intake induced tuning pressure wave forms in the mixture conduit of the carburetor transitting the venturi is eliminated, reduced or modulated by the dynamic pressure exerted by said tuning waves at the pitot tube and transmitted by the vent passageway to said chamber and to said main fuel restriction.

摘要： A system and method for controlling a lean-burning internal combustion engine. The system and method enable a starter carburetor to operate at cold but not at hot temperature, to provide gulp air and counterbalance means for the starter carburetor, together with means to inhibit them at startup and for a brief time thereafter, and to inhibit exhaust gas recirculation when it would be deleterious to smooth operation. The system also provides for continuous accelerator pump operation during acceleration except at high temperatures. The objective is to secure smooth operation at startup, cold, warm or hot, and during transient conditions during engine warmup.

摘要： A minute pressure control system which combines constant positive pressure and constant negative pressure together to control pressure in a controllable object is disclosed. An electronic control circuit generates a train of pulses modulated in accordance with a preset value. The two constant pressures, either one thereof being switched on and off in response to the pulses, are applied to a surge tank to be combined together therein. The surge tank absorbs pressure pulsation resulting from on-off switching application of the pressure and controls the pressure in the controllable object such as a half-closed chamber to the value preset by the electronic control circuit.

摘要： A variable venturi carburetor is described that functions in relation to an internal combustion engine to deliver a homogenous mixture of hydrocarbon fuel and air to the engine cylinders in response to vacuum pressure created through the cylinders. The carburetor includes axially movable venturi members for effectively changing the air volume entering through the primary air duct. Provision is made for maintaining a preselected volume of raw fuel available in a reservoir for instantaneous delivery in response to demand created through various throttle opening conditions. In addition to this feature, I provide mechanism by which the air-fuel ratio is appropriately adjusted automatically in response to changing throttle positions. This is done by changing the "head" or distance from the fuel reservoir level to the fuel outlet orifice, thereby changing the pressure requirements for drawing the fuel from the reservoir to the outlet orifice. A further provision is made in the form of a barometric sensing device that is operatively connected to the carburetor in order to automatically vary the air-fuel ratio in response to varying air pressure conditions at various altitudes.

摘要： A system for controlling pressure in a container, for example the carburetor of an internal combustion engine, from a periodic acoustic source, for example the intake or exhaust of the engine or a selected engine component where the alternating pressure varies only slightly according to engine speed where it is desired to modify the slope of a fuel richness curve over a wide operating range. The system is characterized in that it comprises a conduit connecting the container chamber to the acoustic source, the pressure losses being different according to the direction of flow in the conduit.
