Problems solved by technology

As a result, part of the oil ejected from the oil outlet often flows along the outer wall of the nozzle to the bottom of the throat pipe, resulting in insufficient atomization at the bottom of the throat pipe, which eventually leads to high fuel consumption of the motorcycle, excessive carbon deposits, and exhaust pipe leakage. black smoke

Embodiment approach 1

[0011] As can be seen from Fig. 1, the present invention has carburetor body 1, main nozzle 2, and body 1 has throat pipe 3, and main nozzle 2 comprises main nozzle and comprises pipe body 4 and nozzle 5, and one end of nozzle 5 is outlet The oil port end 6, and the other end is the tail end 7 which is connected with the pipe body 4 as a whole. The outside of the nozzle 5 forms a truncated cone shape. The big head is at the oil outlet end 6 of the nozzle. At the tail end 7 of the nozzle, this can prevent the oil sprayed from the oil outlet from hanging along the outer wall of the nozzle. The nozzle 5 is located in the throat pipe 3, so that the oil outlet is at a certain height from the bottom of the throat pipe. Since there is no fuel hanging on the outer wall of the nozzle, the atomization at the bottom of the throat pipe is more sufficient, effectively achieving the purpose of fuel saving.

Embodiment approach 2

[0012] Implementation Mode 2: See Figure 2

[0013] The change of the outer diameter of the nozzle of the present invention is not limited to the above-mentioned linear reduction of the truncated cone shape, but also can be a nonlinear reduction. As shown in FIG. 2 , the outer diameter of the nozzle 5 in this embodiment is reduced in an arc from the oil outlet end 6 to the tail end 7 .

Embodiment approach 3

[0014] Implementation Mode Three: See Figure 3

[0015] This embodiment is different from the above two embodiments. In this embodiment, the shape of the nozzle is T-shaped.

Abstract

The invention discloses a carburetor, which comprises a body, a main injection tube, a throat on the body, wherein the main injection tube comprises a body and a sprayer, one end of the sprayer is an oil outlet end and the tail end of the other end is integrated with the pipe body as one object, the sprayer lies in the throat, the external diameter of the tail end of the sprayer is less than the external diameter of the oil outlet. The carburetor doesn't make fuel flow and adheres to the bottom of the throat along the external wall of the sprayer and avoids insufficient atomization phenomenon of the throat bottom in the prior technique, thereby the atomization rate of the fuel is improved, the oil consumption is reduced effectively, the fuel is saved and the motorcar carbon deposit and heavy smoke exhaust is reduced.

Description

technical field [0001] The invention relates to a motorcycle carburetor. technical background [0002] In the motorcycle carburetor, the fuel enters the throat through the main nozzle and mixes with the air to become an atomized mixed gas for the engine to function. At present, the main spray pipe of the carburetor includes a pipe body with an oil inlet and a nozzle with an oil outlet, wherein the outer diameter of the nozzle remains unchanged. As a result, part of the oil ejected from the oil outlet often flows along the outer wall of the nozzle to the bottom of the throat pipe, resulting in insufficient atomization at the bottom of the throat pipe, which eventually leads to high fuel consumption of the motorcycle, excessive carbon deposits, and exhaust pipe leakage. black smoke. Contents of the invention [0003] The object of the present invention is to provide a motorcycle carburetor which can effectively save fuel. [0004] This carburetor provided by the present i...
