Abstract
The utility model discloses a plunger-type carburetor used for a motorcycle, which comprises a carburetor body and a plunger arranged inside the carburetor body. A fuel evaporation/desorption port is formed on the carburetor body and connected with a carburetor throat. The plunger-type carburetor has the advantages of simple fabrication, low cost, less modification of the carburetor, moderate and stable pressure of the desorption port, moderate desorption flow, efficient desorption, collection and discharge of the oil gas from the carbon tank, no influence on the engine performance, thereby achieving the purpose of environmental protection and conforming to the fuel evaporation emission standard.
Description
Technical field
The utility model relates to a kind of Carburetor, particularly relates to the plunger type carburetor that uses on the motorcycle.
Background technique
When motorcycle is worked, need to supply inflammable mixture to motor incessantly, at this moment need constantly to allow fuel gasification by Carburetor, and allow fuel oil and a certain proportion of air of vaporization mix mutually to form inflammable mixture and send into motor, satisfy motor different demands to fuel oil under the different operating situation.At present, plunger type carburetor all is not provided with fuel evaporation desorption mouth, thereby can't realize the fuel evaporation Abgasgesetz effectively.Can occur when particularly fuel evaporation desorption mouth is chosen in other positions that desorption mouth negative pressure is low unstable, the desorption flow is little etc. effectively collects oil gas in the desorption charcoal jar, and perhaps the also excessive engine performance that influences of excessive, the flow of desorption mouth negative pressure need increase electromagnetic valve and causes the cost increase.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of reasonable in design, plunger type carburetor that processing motorcycles simple, with low cost, energy-conserving and environment-protective are used.
The technological scheme that its technical problem that solves the utility model adopts is:
The plunger type carburetor that a kind of motorcycle is used comprises in Carburetor body, the Carburetor body being provided with plunger, and described Carburetor body is provided with the fuel evaporation desorption mouth that connects carburetor throat;
As improvement of the technical scheme, described fuel evaporation desorption mouth is arranged between the idle adjusting screw post and float chamber of Carburetor body, and it is corresponding to adjust skewed slot with the idling on the plunger;
As improvement of the technical scheme, on the corresponding Carburetor body of acceleration cable groove that described fuel evaporation desorption mouth is arranged on plunger;
As improvement of the technical scheme, described fuel evaporation desorption mouth is arranged on the crossover location of the preceding float chamber of Carburetor body chock plate erection column.
The beneficial effects of the utility model are: the design have processing simple, with low cost, little to the change of Carburetor, desorption mouth negative pressure is moderate and stable, the desorption flow is moderate, thereby realize collecting exhaust of oil in effective desorption canister, do not influence advantages such as engine performance again, reach the purpose of environmental protection, satisfy the fuel evaporation Abgasgesetz.

Embodiment
The plunger type carburetor that a kind of motorcycle is used comprises in Carburetor body 1, the Carburetor body 1 being provided with plunger 2, and described Carburetor body 1 is provided with the fuel evaporation desorption mouth 3 that connects carburetor throat.
With reference to Fig. 1, Fig. 2, described fuel evaporation desorption mouth 3 is arranged between the idle adjusting screw post 11 and float chamber 12 of Carburetor body 1, it is corresponding to adjust skewed slot 21 with the idling on the plunger 2, and described fuel evaporation desorption mouth 3 is provided with fuel evaporation desorption straight tube 4; Also can be provided with fuel evaporation desorption bend pipe 5 as required on the fuel evaporation desorption mouth 3, see Fig. 3, the design utilizes the idling adjustment skewed slot 21 on the plunger 2 to carry out the fuel evaporation desorption as the passage that connects carburetor throat.The design of this fuel evaporation desorption mouth 3 the most rationally, the simplest, the negative pressure of processing stablize moderate, the desorption flow is also moderate.
With reference to Fig. 4, Fig. 5, described fuel evaporation desorption mouth 3 is arranged on the acceleration cable groove 22 corresponding Carburetor bodies 1 of plunger 2, and described fuel evaporation desorption mouth 3 is provided with fuel evaporation desorption bend pipe 5; The design utilizes the acceleration cable groove 22 on the plunger 2 to carry out the fuel evaporation desorption as the passage that connects carburetor throat.The design processing of this fuel evaporation desorption mouth 3 is simple, but the position is higher, and the acceleration cable groove 22 on the plunger 2 is less, and it is little to adjust the space, can be used as the selection scheme at different automobile types fuel evaporation desorption coupling.
With reference to Fig. 6, described fuel evaporation desorption mouth 3 is arranged on any point on the crossover location of float chambers 12 before the Carburetor body 1 chock plate erection column 6.Described fuel evaporation desorption mouth 3 is provided with fuel evaporation desorption straight tube 4, the design is directly led to plunger 2 outer walls and is utilized plunger 2 to be up to connect carburetor throat after certain aperture and carry out the fuel evaporation desorption, the design of this fuel evaporation desorption mouth 3 has bigger coupling and adjusts the space, can adjust caliber size at different negative pressure and obtain moderate desorption flow, the time of opening of fuel evaporation desorption mouth 3 also has the height that big package space can be adjusted fuel evaporation desorption mouth 3 according to the engine performance demand, is implemented in different rotating speeds and opens the desorption mouth.
The design have processing simple, with low cost, little to the change of carburetor, take off Attached mouthful negative pressure is moderate and stable, the desorption flow is moderate, thereby realizes effective desorption canister The middle exhaust of oil of collecting does not affect again the advantages such as engine performance, reaches the order of environmental protection , satisfy the EVAP Abgasgesetz.
