摘要： A variable venturi carburetor comprises an auxiliary intake air passage, an auxiliary variable venturi and a non-adjustable nozzle portion, in addition to a main intake air passage, a main variable venturi and an adjustable nozzle portion. If the amount of intake air is small as when the engine is being idled, intake air is passed mainly through the auxiliary variable venturi to generate vacuum sufficiently high to jet fuel into the auxiliary intake passage through the non-adjustable nozzle portion. If the amount of intake air is great as when the engine is running under a heavy load, intake air is passed mainly through the main variable venturi. Since two venturis are formed, it is possible to smoothly increase the amount of fuel to be jetted into the intake passage over a wide engine operating condition.
摘要翻译： 除了主进气通道，主可变文丘里管和可调喷嘴部分之外，可变文丘里化油器包括辅助进气通道，辅助可变文丘里管和不可调喷嘴部分。 如果当发动机空转时进气量小，则进气主要通过辅助可变文丘里管，以产生足够高的真空，从而通过不可调节的喷嘴部分将燃料喷射到辅助进气通道中。 如果当发动机在重载下运行时进气量大，则进气主要通过主可变文丘里管。 由于形成了两个通风口，因此能够在较宽的发动机运转状况下平稳地增加喷射到进气通路内的燃料量。

摘要： A carburetor for combustion engines with a mixing chamber in the carburetor housing, the mixing chamber being bounded downstream by a randomly actuated mixture throttle and upstream by an air throttle controlling the intake air cross section and actuated by the pressure prevailing in the mixing chamber. A bypass air duct discharges into the center of the mixing chamber and receives the fuel supply. A nozzle pin cooperates with the air throttle and controls the cross section of a fuel jet. Downstream of this jet is another fuel jet whose cross section is controllable as a function of engine operating parameters by means of an analog magnet. The fuel jet controlled by the analog magnet may be the fuel outlet in the bypass air duct, and may be controlled by a nozzle pin through a lever via the analog magnet which is a plunger system. The second fuel jet may be located in a bypass air duct and its cross section may also be controlled by an analog magnet as a function of engine operating parameters. The analog magnet may be excited via a regulator with a sinusoidal modulated direct current.

摘要： A fuel injection system for continuous injection of fuel into the induction tube of an internal combustion engine. The induction tube includes adjacent convergent and divergent regions. A throttling element, composed of two conical parts with adjoining bases forms a narrow, annular aperture in cooperation with the diverging region of the induction tube. The throttling element can slide along its axis and its position determines the setting of a control slide within a fuel metering valve assembly which relates the metered out fuel quantity to the air flow through the narrow annular aperture. A bellows mechanism and a lever limit the axial excursion of the throttle element so as to maintain a minimum vacuum in the induction tube. The system also includes a gas-pedal linked cam plate which sets the location of the fulcrum for the limiting lever.

摘要： A combustible mixture of air and minute fuel droplets is produced for supply to the cylinders of an internal combustion engine. This mixture is formed by accurately controlling both the atomization of fuel and the mass flow rate of air over substantially the entire operating range of the engine. These controls are accomplished by introducing liquid fuel into a stream of intake air and uniformly distributing the fuel in the air followed by passing the air and fuel mixture through a constricted zone to increase the velocity of the mixture to sonic. The sonic velocity air at the constricted zone divides the fuel into minute droplets that are uniformly entrained throughout the air stream. The area of the constricted zone and the quantity of fuel introduced are adjustably varied in correlation with operating demands imposed upon the engine. Downstream from the constricted sonic zone, the air and fuel mixture is accelerated to supersonic velocity in a supersonic zone without imparting substantial turbulent flow thereto. Thereafter the mixture is decelerated to subsonic velocity in a subsonic zone to produce a shock zone where the fuel droplets entrained in the air are believed to be further subdivided and uniformly distributed throughout the combustible mixture before the mixture is supplied to the engine cylinders.
摘要翻译： 产生空气和微小燃料液滴的可燃混合物供给内燃机的气缸。 该混合物通过在发动机的基本上整个工作范围内精确地控制燃料的雾化和空气的质量流量来形成。 这些控制是通过将液体燃料引入进气流并将燃料均匀分布在空气中，然后将空气和燃料混合物通过收缩区域来提高混合物的声速来实现的。 收缩区域的声速空气将燃料分成均匀地夹在整个空气流中的微小液滴。 收缩区域的面积和引入的燃料量可以根据施加在发动机上的操作要求而变化。 在缩小的声波区域的下游，空气和燃料混合物在超音速区域被加速到超音速，而不会对其产生大量的湍流。 此后，混合物在亚音速区域中减速至亚音速，产生冲击区，其中夹带在空气中的燃料液滴被认为在将混合物供应到发动机气缸之前进一步细分并均匀分布在整个可燃混合物中。
