摘要： A carburetor for an internal combustion engine includes idle passages (22A and 22B) extending through the carburetor body adjacent each cylinder bore (18a-18-D) of the carburetor, such that the idle passages bypass the cylinder bores. A common fuel flow metering circuit (30) is in fluid communication with at least two of the idle passages for joining the fuel flowing from the idle passages and redistributing the fuel back to the idle passages. A metering valve (40) is positioned in the common fuel flow circuit for metering the flow of fuel through the common fuel flow metering circuit, so that equal distribution of the fuel is delivered to the cylinders of the engine in spite of possible unequal flow of fuel being received through the idle passages.

摘要： A fuel-air-mixture-forming device for an internal combustion engine, has a nozzle body (2) of rotational symmetry which, together with a throttle body (7) of rotational symmetry which is displaceable in the nozzle body, forms a convergent-divergent nozzle (10) which debouches into an intake pipe of the internal combustion engine. A fuel air slot (11) surrounds the convergent-divergent nozzle and debouches via a circumferential slot opening (12) into the nozzle. Fuel mixed with air is injected from the slot opening into the nozzle via a direction approximately transverse to the direction of the main air mass flow (L). In order to obtain an equalization of the closing forces caused by the vacuum on the throttle body, in accordance with the invention, the throttle body has an inner space (27) which is closed off from the nozzle and is provided with at least one pressure equalization cutout (28) which connects the nozzle with the inner space.

摘要： A flow regulating carburetor having a movable control element operating within the throat of a venturi air passage, the element being automatically displaced to vary the effective size of the throat as a function of the mass-volume of the air stream flowing through the passage. This produces a velocity-pressure differential acting automatically to regulate the quantity of fuel induced through a fuel tube communicating with the throat and intermingling with the air stream to provide a ratio of air-to-fuel representing the optimum value for the prevailing condition of engine speed and load throughout the entire engine operating range, thereby effecting a marked improvement in fuel economy and reducing the emission of pollutants.

摘要： An automatic control system for supplying a fuel-air mixture to an internal combustion engine through a Venturi structure conducting throttle-controlled incoming air to the intake manifold of the engine. Coaxially disposed in the casing of the structure is a cylindrical booster whose internal surface has a Venturi configuration to define a primary passage. Interposed between the booster and a ring having an external Venturi configuration mounted on the casing in an axially shiftable spool whose internal surface has a Venturi configuration to define a secondary passage having a variable throat between this surface and the spool. A tertiary passage is defined between the outer surface of the spool and the ring, incoming air passing through all three passages. An air-fuel dispersion is fed into the primary passage to intermingle with air flowing therethrough to create an atomized mixture which is fed through the variable throat of the secondary passage to further atomize the mixture which is then fed into the manifold. The air pressure difference between the inlet to the Venturi and the effective throat of the combined passages is sensed to produce a command signal for governing a servo motor in a closed loop arrangement to adjust the axial position of the spool to attain an optimum fuel-air ratio.

摘要： An automatic control system for supplying a fuel-air mixture to an internal combustion engine including a variable-Venturi carburetor. Air is fed into the input of the Venturi, the air passing through the throat thereof whose effective area is adjusted by a mechanism operated by a servo motor. Fuel is fed into the input of the Venturi from a fuel reservoir through a main path having a fixed orifice and an auxiliary path formed by a metering valve operated by an auxiliary fuel-control motor. The differential air pressure developed between the inlet of the Venturi and the throat thereof is sensed to produce an air-velocity command signal that is applied to a controller adapted to compare the command signal with the servo motor set point to produce an output for governing the servo motor to cause it to seek a null point, thereby defining a closed process control loop. The intake manifold vacuum, which varies in degree as a function of load and speed conditions is sensed to govern the auxiliary fuel-control motor accordingly, is at the same time converted into an auxiliary signal which is applied to the controller in the closed loop to modulate the command signal in a manner establishing an optimum air-fuel ratio under the varying conditions of load and speed.
