Abstract
The utility model relates to an external radiant-type main jet of a carburetor, which is characterized in that a jet body is processed to be a streamline-shaped cylinder and is positioned at the central position of a small throat. Ambient rounding gaps are processed at the external ring position of the streamline-shaped cylinder to form the main jet. The streamline-shaped cylinder and the small throat are integrated by manufacture and are arranged on a middle body of the carburetor and are positioned at the center of an air inlet, and an internal hole oil channel is communicated with a main oil channel of the carburetor. When air current flows through the small throat, i.e., the air current flows around the streamline-shaped cylinder, vacuum is produced in the gaps of the main jet and gasoline is sucked from the gaps to be scattered to form the atomization. The utility model has the advantages of simple structure, easy processing, long service life, etc.
Description
The utility model belongs to the Carburetor parts, is a kind of improvement of gasoline atomizing technology.
At present, existing carburetor main spout great majority all are single holes, garden, and the gasoline particle volume of ejection is bigger, and in gasoline when ejection, is little with the tangent plane mutually of air draught, and when some operating mode of motor, the atomizing effect of gasoline is not good, mixed gas quality is poor, and engine fuel consumption is big.
The purpose of this utility model is can put the dispersive nozzle that the platform motor is worked for Carburetor provides a kind of under various operating modes, strengthens the atomizing effect of gasoline, improves mixed gas quality.
The technical solution of the utility model is under the situation that air mass flow and flow velocity were constant originally, and main injection jet was stitched by the export-oriented garden week of making into to equate with Qi Yuan hole sectional area to the hole, garden in original single.Original little tens of times to the hundreds of times granule that scatters of volume ratio when making the gasoline ejection.Simultaneously, the gasoline of ejection increases several times with the tangent plane mutually of air draught, and the atomizing effect of gasoline is strengthened, and improves mixed gas quality, makes motor reduce fuel consumption.
Feature of the present utility model is processed into the streamline Cylinder with nozzle body and is positioned at the small venturi central position, makes main injection jet around the slit around the processing of streamline Cylinder outer shroud place.Streamline Cylinder external radiation shape oil spout all around when fuel-displaced.
Working principle of the present utility model and good effect are: streamline Cylinder and small venturi are manufactured one be installed on the carburetter connector, be positioned at air inlet central authorities.The endoporus oil duct communicates with the carburetor main oil duct.When air draught flows through in small venturi, when just around the streamline Cylinder, flowing through, make in the main injection jet slit and produce vacuum, gasoline sucking-off from the slit is broken up, form atomizing.The utlity model has advantages such as simple in structure, easy processing, long service life.
Accompanying drawing is a structure sectional view of the present utility model.
In Fig. 1, be illustrated in the middle trunnion 1 of Carburetor and be connected with small venturi 2, streamline Cylinder 3 is housed at small venturi 2 central positions, streamline Cylinder 3 outer rings be processed with one week seam as main injection jet 4, main injection jet 4 is communicated with endoporus oil duct 6 and air jet 5.
