Abstract
The utility model discloses a carburetor plunger structure, which comprises a plunger, wherein an air guide groove is concavely arranged on one surface of the plunger, which is close to an air inlet of a carburetor, and two sides of the air guide groove are obliquely arranged towards the middle part; the air guide groove extends to the lower end face of the plunger; the two sides of the air guide groove are uniformly inclined towards the middle part, and the air guide groove forms an arc shape at the lower end surface; the whole air guide groove is an arc-shaped groove, and the periphery of the arc-shaped groove is gradually recessed towards the middle part. The utility model has simple structure and reasonable design, and the air entering the air inlet can enter the throat of the carburetor through the air guide groove by arranging the air guide groove on one surface of the plunger close to the air inlet of the carburetor, so that the air can be more contacted with fuel, and the fuel atomization efficiency is improved.
Description
Technical Field
The utility model relates to the technical field of motorcycle engines, in particular to a carburetor plunger structure.
Background
In the carburetor of the motorcycle, fuel enters the throat through the main spray pipe to be mixed with air, so as to become atomized mixed gas for the engine to function. The purpose of changing the width of the throat is achieved by changing the height of the plunger. In this case, since the face of the plunger facing the air inlet of the carburetor is generally flat, air collides with the flat face of the plunger when passing through the air inlet, and turbulence is caused.
Disclosure of Invention
The utility model overcomes the defects of the prior art, and provides a carburetor plunger structure, wherein the air guide groove is arranged on one surface of the plunger, which is close to the air inlet of the carburetor, so that air entering the air inlet can enter the venturi of the carburetor through the air guide groove, the air can be contacted with fuel more, and the fuel atomization efficiency is improved.
In order to achieve the above purpose, the present utility model provides the following technical solutions:
a carburetor plunger structure comprises a plunger, wherein an air guide groove is concavely formed in one surface of the plunger, which is close to an air inlet of a carburetor, and two sides of the air guide groove are obliquely arranged towards the middle.
Preferably, the air guide groove extends to the lower end face of the plunger.
Preferably, both sides of the air guide groove are uniformly inclined towards the middle part, and the air guide groove forms an arc shape at the lower end surface.
Preferably, the air guide groove is an arc-shaped groove, and the periphery of the arc-shaped groove is gradually recessed towards the middle part.
The utility model has the beneficial effects that:
the utility model has simple structure and reasonable design, and the air entering the air inlet can enter the throat of the carburetor through the air guide groove by arranging the air guide groove on one surface of the plunger close to the air inlet of the carburetor, so that the air can be more contacted with fuel, and the fuel atomization efficiency is improved.
Drawings
FIG. 1 is a schematic view of a usage state of an embodiment of the present utility model;
FIG. 2 is a schematic diagram showing a plunger structure according to an embodiment of the present utility model;
FIG. 3 is a schematic diagram showing a second embodiment of the present utility model.
In the figure: 1. a plunger; 11. a lower end surface; 2. a carburetor air inlet; 3. an air guide groove.
Description of the embodiments
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
1-3, the carburetor plunger structure comprises a plunger 1, wherein an air guide groove 3 is concavely arranged on one surface of the plunger 1 close to a carburetor air inlet 2, and two sides of the air guide groove 3 are obliquely arranged towards the middle; the air guide groove 3 extends to the lower end face 11 of the plunger 1; the two sides of the air guide groove 3 are uniformly inclined towards the middle part, and the air guide groove 3 forms an arc shape at the lower end surface 11; the air guide groove 3 is an arc-shaped groove, and the periphery of the arc-shaped groove is gradually concaved towards the middle part.
Through adopting the technical scheme, in the utility model, the air guide groove 3 is integrally arranged into an arc groove shape, and the periphery of the arc groove is gradually and uniformly inclined and concavely arranged towards the middle part, so that when air enters the air inlet 2 of the carburetor, the air enters the throat from the air guide groove 3, the situation that the air collides with the plunger 1 to generate turbulence is reduced, the air can be contacted with fuel more, and the fuel atomization efficiency is improved.
The foregoing is only a preferred embodiment of the present utility model, but the scope of the present utility model is not limited thereto, and any person skilled in the art, who is within the scope of the present utility model, should make equivalent substitutions or modifications according to the technical scheme of the present utility model and the inventive concept thereof, and should be covered by the scope of the present utility model.
Claims (3)
1. The utility model provides a carburetor plunger structure, includes plunger, its characterized in that, the plunger is close to the concave air guide groove that is provided with in the one side of carburetor air inlet, and the both sides of air guide groove slope setting to the middle part, and the air guide groove extends to the lower terminal surface of plunger, and the air guide groove forms the arc shape in lower terminal surface department.
2. A carburetor plunger structure according to claim 1, wherein both sides of the air guide groove are inclined uniformly toward the middle.
3. A carburetor plunger structure according to claim 1 or 2, wherein the air guide groove is an arc-shaped groove, and the periphery of the arc-shaped groove is gradually recessed toward the middle.
