Abstract
The utility model relates to a carburetor used for a motorcycle, which comprises a float chamber. An air balance tube opening, an oil overflowing tube opening, a main metering jet mounting column, an idle metering jet mounting column and a needle valve seat are arranged in the float chamber; a partition plate is arranged in the cavity of the body, and extends from top down to a position lower than the set oil surface position of the float chamber of the carburetor; the partition plate divides the air chamber of the upper part of the float chamber into a left chamber and a right chamber; the air balance tube opening and the oil overflowing tube opening are positioned in the left and the right chambers respectively. The carburetor has the advantages of simple structure, good reliability, small change and basic no addition of cost, not only can reduce the evaporation emission quantity of the gasoline in the carburetor, but also cannot change the original functions of the air balance tube and the oil overflowing tube of the carburetor, and cannot affect engine performance, thereby achieving the purpose of environmental protection and meeting the requirements of laws and regulations of fuel oil evaporation emission.
Description
Technical field
The utility model relates to the Carburetor that a kind of motorcycle is used.
Background technique
When stopping after the motorcycle work, the temperature transfer of motor is to Carburetor.Gasoline steam output in the Carburetor is bigger at this moment, directly is evaporated to contaminated air in the atmosphere under the convection action of atmospheric equilibrium pipe and oil spill pipe, has influence on the discharging of car load fuel evaporation.
Three kinds of schemes are arranged at present: 1. motorcycle carburetor atmospheric equilibrium pipe and oil spill pipe directly lead to atmosphere, and the harmful gas that the gasoline in the Carburetor is evaporated directly is discharged to contaminated air in the atmosphere, and this will directly improve the discharge amount of exhaust gas of motorcycle.2. motorcycle carburetor atmospheric equilibrium pipe and oil spill pipe connect canister, directly are discharged to contaminated air in the atmosphere though can control the harmful gas that the gasoline in the Carburetor is evaporated like this; But the performance to car load can affect, and the cost increase is more, reliability is bad.3. by three-way pipe or four-way pipe atmospheric equilibrium pipe and oil spill pipe are connected together, make the indoor air of carburettor float not form convection current by atmospheric equilibrium pipe and oil spill pipe, the oil vapor that reaches in the control Carburetor is discharged to air-polluting purpose in the atmosphere; But shortcomings such as car load line arrangement complexity, installation difficulty, integral vehicle cost increase.
The model utility content
In order to overcome the deficiencies in the prior art, the utility model provides the motorcycle Carburetor that a kind of simple in structure, good reliability, cost are low, can effectively reduce the discharging of float chamber oil vapor.
The technological scheme that the utility model adopted is:
The Carburetor that a kind of motorcycle is used, comprise float chamber, be provided with the atmospheric equilibrium mouth of pipe, the oil spilling mouth of pipe, main jet erection column, idle metering jet erection column, pintle valve seat in the float chamber, the inner chamber of described body is provided with dividing plate, described dividing plate is down extended to the setting pasta position that is lower than carburetor bowl by the top, this dividing plate is divided into left and right cavity with the air cavity on float chamber top, and the atmospheric equilibrium mouth of pipe and the oil spilling mouth of pipe lay respectively in the left and right cavity.
Further improvement of the utility model, described dividing plate be main jet erection column, idle metering jet erection column, pintle valve seat with the float chamber inwall between the stiffening rib that is connected successively.
The beneficial effects of the utility model are: be provided with will the work air cavity on pasta top of dividing plate at float chamber and separate, the atmospheric equilibrium mouth of pipe and the oil spilling mouth of pipe lay respectively in the left and right cavity, during working state behind float chamber topping up body, the air of left and right cavity can not circulate, but liquid communication, air when this design makes Carburetor in working order in the float chamber can not form convection current by atmospheric equilibrium pipe and oil spill pipe, thereby prevent that oil vapor from by atmospheric equilibrium pipe and oil spill pipe discharge, reducing the pollution to environment; Make the discharging of car load fuel evaporation descend more than 90%; Further, dividing plate be main jet erection column, idle metering jet erection column, pintle valve seat with the float chamber inwall between the stiffening rib that is connected successively.The design is simple in structure, the change of good reliability, Carburetor is little, cost does not increase substantially, both can realize effectively reducing the gasoline discharge vaporization amount in the Carburetor, can not change the original function of Carburetor atmospheric equilibrium pipe and oil spill pipe again, do not influence engine performance yet, reach the purpose of environmental protection, satisfy the fuel evaporation Abgasgesetz.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of another angle of the utility model.
Embodiment
With reference to Fig. 1, shown in Figure 2, the Carburetor that a kind of motorcycle is used, comprise float chamber 1, be provided with the atmospheric equilibrium mouth of pipe 2 in the float chamber 1, the oil spilling mouth of pipe 3, main jet erection column 4, idle metering jet erection column 5, pintle valve seat 6, the inner chamber of body is provided with dividing plate 7, dividing plate 7 is down extended to the setting pasta position that is lower than carburetor bowl 1 by the top, that is to say, in the process of work, the bottom of dividing plate will stretch into designed work pasta A below, this dividing plate 7 is divided into a left side with the air cavity on float chamber 1 top, right cavity 8,9, the atmospheric equilibrium mouth of pipe 2 and the oil spilling mouth of pipe 3 lay respectively at a left side, right cavity 8, in 9.This design can be effectively separates the left and right cavity 8,9 on float chamber top, does not influence again between the liquid of float chamber bottom to flow.
Claims (2)
