    摘要: A carburetor having a carburetor body in which an intake channel portion is formed. At least one fuel opening opens out into the intake channel portion. Pivotably mounted in the intake channel portion is a butterfly valve that in a completely opened position divides the intake channel, in the region of the butterfly valve, into a mixture channel and a feed channel, so that in the completely opened position of the butterfly valve, flowing into the feed channel is combustion air having a fuel content that is less than the fuel content in the mixture channel. Provided in the intake channel portion is at least one partition section that extends between the feed channel and the mixture channel. The partition section is formed on the carburetor body.

    摘要: A carburetor and a fuel seeding system having the same including an air suction passageway through which air is fed, and a fuel feeding passageway which is disposed so as to be intersected to the air suction passageway and through which fuel is fed, the air suction passageway and the fuel feeding passageway being intercommunicated to each other. A roughened surface portion is formed on a wall surface of at least one of the air suction passageway and the fuel feeding passageway to generate turbulence in fluid flow and promote carburetion and granulation of the air-fuel mixture due to the turbulence. The tip portion of a jet needle serving as a part of the fuel feeding passageway may be provided with a substantially flat surface portion or a substantially conical surface portion having a vertical angle above 145 degrees.

    摘要: A carburetor including a throttle valve for regulating the flow of air through the body of the carburetor and to an engine, with fuel being introduced into the air flow for intermixture therewith, and with the device including an air actuated element which is preferably located downstream of the throttle valve and is adapted to be displaced automatically by the air to different positions varying in correspondence with the rate of air flow through the device, and which forms a restriction varying in size with the rate of air flow and acting to enhance dispersal of the fuel within the air and assure intimate intermixture of the air and fuel for optimum functioning of the engine. The fuel may be premixed with a secondary flow of air before delivery of the fuel and secondary air as a combined stream into the primary flow of air, and the combined stream may be drawn by vacuum into the primary flow of air at the location of the restriction formed by the flow actuated member. Precise control of the amount of fuel which is fed into the primary flow is attained by automatic regulation of a valve controlling the amount of secondary air which is mixed with the fuel. A proper air-fuel ratio may be assured by utilizing movement of the air actuated element to control operation of the secondary air valve. Additional automatic controls for starting and idle purposes are actuated by a vacuum responsive element and a thermostatic element.

    摘要: A cold-engine operation detector is provided for producing a cold-engine signal when engine temperature is lower than a predetermined temperature, and an idle engine speed detector is provided. A dead zone for input of engine speed with respect to desired engine speed in accordance with engine temperature is stored in a memory. Width of the dead zone is provided to increase with decrease of engine temperature. A range of the dead zone in accordance with engine temperature is derived from the memory. When actual engine speed is out of a derived range of the dead zone, an actuator provided in an idle speed control system is operated for controlling the actual engine speed to the desired engine speed.

    摘要: The method of locating and cutting an idle bypass hole in a carburetor body having a throttle section and a normally closed pivotal throttle plate therein on a longitudinal axis which comprises adjustably and guidably mounting a carrier upon a fixture base, locating and clamping a carburetor body upon the carrier and mounting a stationary contact finger upon the base. Further steps include advancing the carburetor body until the contact finger is in firm engagement with the throttle plate, thereafter clamping the carrier to the base and successively cutting the idle bypass hole through the carburetor body upon an axis at right angles to the body axis and at a predetermined distance to a fixed axis of reference. The cutting axis is arranged at a preset critical distance from the closed throttle plate. An apparatus therefor which includes a fixture base, a reciprocal carrier guidably mounted thereon supporting a carburetor body. A fixture support upon the base mounts a control rod carrying a contact finger which on inward feed of the carrier comes into firm contact with the throttle plate. Upon clamping of the carrier to the base, a laser cutting unit having a cutting and axis at right angles to the body axis is energized. The cutting axis is at a predetermined center distance to a fixed axis of reference and arranged at a preset critical distance from the closed throttle plate.

    摘要: A unique supplemental carburetion device for internal combustion engines producing a primary source of fuel-air mixture for use at idle and low engine speeds resulting in decreased fuel consumption and exhaust emissions comprising a fuel reservoir chamber joined to a source of liquid fuel and determinate fluid communication with a fuel metering chamber. The metering chamber preferably is vented to ambient air pressure contains diaphragm valve means for controlling fluid flow into the metering chamber. Liquid fuel from the metering chamber flows into a nebulizing chamber and is nebulized by interaction with a stream of ambient air or blow-by gases. The fuel-air stream is passed into a venturi throat and vaporized and then passed into an expansion chamber where the stream is expanded under low static gas pressure to a mixture having a pre-determined fuel to air ratio. The mixture exits the device and is delivered into downstream portions of the carburetor throat.
