Embodiment Construction

[0016] see figure 2 .A dual-fuel automobile carburetor throat, including a cylinder with a cavity, the lower end is provided with a collar 2, and a funnel-shaped cavity formed by two opposite cones of the cylinder, and an elliptical cavity is arranged in the middle of the cavity. The cavity 1 is provided with through holes around the cavity 1.

[0017] see figure 1 , figure 2 , image 3 , its working process is:

[0018] When the car is at rest, the pressure of the natural gas is equal to the pressure of the steam, the natural gas does not flow, and the original static state is maintained.

[0019] When the car engine rotates, the carburetor generates downward suction, and the air flows downward rapidly, and the flow direction flows from C to E. In the cavity 1 in the middle of the throat, a certain vacuum (negative pressure) is generated to make the natural gas flow, and the natural gas flows from F1 and F2 flow through the through holes D1, D2 and D3 to the through gr...

Abstract

The invention relates to a carburetor hollow throat of a dual-fuel automobile. In an input method of natural gas of the traditional automobile, the natural gas is sucked from the upper end of the carburetor, thus the input method has the following problems that the fixing performance is poor, the atomizing proportion is inconsistent and the mixture ratio is not easy to control; the technical level of the assembly and the matching of the traditional automobile filter and an engine is damaged to cause the effect of the filter to be reduced and the stability to be poor. The carburetor hollow throat of the dual-fuel automobile comprises a cylinder with a cavity, wherein the cylinder is a funnel-shaped cavity formed by two opposite cones; an elliptical cavity is arranged in the middle of the cavity; and the periphery of the cavity is provided with through holes. The invention can be directly matched with the carburetor of the traditional automobile for use, so that an air inlet system of the automobile is further improved; in addition, the invention has favorable stability and low cost.

Description

1. Technical field [0001] The invention relates to an automobile fuel carburetor device, in particular to a dual-fuel car carburetor throat. 2. Background technology [0002] The current natural gas input method of Jiefang Automobile is sucked from the upper end of the carburetor, and its problems include: poor fixing performance, inconsistent atomization ratio, difficult control of the mixing ratio, and damage to the original installation and cooperation technology of the car filter and the engine Level, the effect of the filter is reduced, and the stability is poor. 3. Contents of the invention [0003] The object of the present invention is to overcome the disadvantages of the above-mentioned background technology, and provide a dual-fuel automobile carburetor throat, which can be matched with the existing car carburetor, so as to further improve the technology of the car steam inlet system. [0004] To achieve the above object, the technical solution adopted in the pr...
