摘要： A carburetor includes a body and a fuel bowl coupled to the body. A fuel bowl chamber is defined by the body and the fuel bowl. A fuel supply passageway fluidly couples a fuel supply inlet of the carburetor with the fuel bowl chamber. A fuel metering unit is coupled to the body of the carburetor. A first filter is disposed in one of the fuel supply passageway and the fuel bowl chamber, and a second filter is disposed in the fuel metering unit.

摘要： An improved carburetor metering block for converting a conventional gasoline carburetor to alcohol fuel involving a carburetor metering block means adapted to attach to a conventional carburetor and replace the removable fuel bowl and standard metering block wherein the improved carburetor metering block means is adapted to accept, simultaneously, a plurality of individual and separate fuel bowls. Such a device can inexpensively convert a conventional carburetor to the use of alcohol fuel consistent with sufficient fuel flow and adequate fuel level control.

摘要： A carburetor having an idle nozzle and a main nozzle each with a fixed flow area and an idle speed single adjustment screw adjustable by the user. The idle and high speed fuel flows are controlled by the idle nozzle and the main nozzle, respectively. The user can adjust the engine speed only by adjustment of the idle speed adjustment screw which changes the position of the carburetor throttle valve to control the flow through the carburetor. This provides a more consistent fuel and air mixture to improve the performance of the engine and better control engine emissions by preventing the user from changing the fuel and air ratio to a mixture which is either too lean or too rich for the steady and low level exhaust emission operation of the engine.
摘要翻译：具有怠速喷嘴的化油器和各自具有固定流动面积的主喷嘴和用户可调节的怠速单次调节螺钉。怠速和高速燃料流量分别由怠速喷嘴和主喷嘴控制。用户只能通过调节怠速调节螺丝来调节发动机转速，从而改变化油器节流阀的位置，以控制通过化油器的流量。这提供了更一致的燃料和空气混合物以改善发动机的性能并且通过防止使用者将燃料和空气比改变为对于稳定和低水平排气来说太稀或太浓的混合物来更好地控制发动机排放发动机的排放作业。

摘要： An asymmetrical orifice for bypass control in a clean fuel module may include a body having first and second end surfaces and an inner surface defining a bore through the body extending from a first opening through the first end surface to a second opening through the second end surface. The first opening has a first opening inner diameter and the second opening has a second opening inner diameter that is less than the first opening inner diameter. The asymmetrical orifice also includes a flow control contour in the second end surface surrounding the second opening of the bore. The configuration may give the asymmetrical orifice a first discharge coefficient for fluid flowing from the first opening to the second opening that is greater than a second discharge coefficient for fluid flowing in a second direction from the second opening to the first opening.

摘要： A carburetor attachment is designed for replacing a main jet(s) found in the float chamber of a carburetor. The attachment comprises an elongated tubular member with a bore running therethrough and presenting an opening at the lower end thereof. Threads at the lower end of the tubular member fasten the attachment to the threaded socket presented by removal of the normal main jet. In place, the upper end of the attachment extends above the normal level of the fuel found in the float chamber and has a port thereat providing communication between the internal bore and the surrounding ambient air. An inclined port adjacent the lower end of the tubular member provides a conduit between the surrounding fuel and internal bore. Upon actuation of the carburetor the resulting suction presented within the bore draws the surrounding ambient air and fuel through the respective ports for admixture therein. The resulting mixture is drawn through the opening for subsequent conveyance, through conventional passage means, to the main body of the carburetor.
摘要翻译：化油器附件设计用于更换化油器浮子室中发现的主喷射器。该附件包括细长的管状构件，其具有贯穿其中的孔，并且在其下端具有开口。管状部件下端的螺纹通过拆卸普通主喷嘴将附件固定到螺纹插座上。在适当位置，附件的上端延伸超过在浮子室中发现的燃料的正常水平面，并且在该孔口处提供内孔和周围环境空气之间的连通。邻近管状构件的下端的倾斜端口在周围的燃料和内部孔之间提供导管。在致动化油器时，在孔内引起的所得吸力将周围的空气和燃料通过相应的端口吸入，用于混合在其中。所得到的混合物通过开口被拉出，以便随后通过传统的通道装置输送到化油器的主体。

摘要： A carburetor including a body having a main bore through which a fuel and air mixture is discharged from the carburetor for use by an engine a priming passage communicated with the main bore, a pump that moves fluid into the priming passage, and a flow restrictor received within at least a portion of the priming passage to reduce the minimum effective flow area of the priming passage. The flow restrictor has a body received at least partially within the priming passage so that fluid flows around the flow restrictor and between the structure defining the priming passage and the flow restrictor.

摘要： A device for uniform distribution of a two-phase flow containing a liquid and a gaseous component, in particular a fuel-air mixture in a mixture delivery arrangement of an automobile, the device being provided with a flow-in line bore arranged centrally in a housing as well as with a plurality of flow-out line bores extending essentially in a plane perpendicular to the flow-in line and communicating with the flow-in line bore. The flow-in line bore is bounded by the end face of an obturating body which is pressed into a retaining bore arranged coaxially with the flow-in line bore but beyond the plane of the flow-out line bores. In order to create an optimal, uniform distribution effect coupled with a favorable possibility to check the formation of burrs or ridges in the zone of the intersecting edges of the bores, the diameter of the retaining bore is to be rendered substantially larger than the diameter of the flow-in line bore, and between the end face of the obturating body and the bottom of the retaining bore is formed a distribution space in the form of a narrow gap into which the flow-out line bores open.
