Description

Pure liquefied petroleum gas carburetor

Technical field

The utility model relates to a kind of carburetors, and in particular to a kind of pure liquefied petroleum gas carburetor.

Background technique

Liquefied petroleum gas is oil plant, oil gas field and using coal as waste liquid fuel during a kind of byproduct.It It is had many advantages as automotive fuel.For the low heat value of liquefied petroleum gas generally in 45036 ~ 45870kj/kg, theory is mixed The low heat value for closing gas is closer to gasoline theoretical mixture gas, therefore liquefied petroleum gas is used as automotive fuel, substantially in holding The original dynamic property of combustion engine and economic index, and it is not big reduction.Liquefied petroleum is used as fuel to normal engine Combustion chamber will be changed when machine fuel feeding, improves compression ratio, using dedicated mixer structure, be increased carburetor air door aperture, changed Exhaust pipe etc. is put into, however the characteristics of this scheme is engine performance can be made to greatly improve, but reequip heavy workload.

Summary of the invention

To solve the above problems, the purpose of this utility model is to provide a kind of simple and reliable for structure and high-efficient pure Liquefied petroleum gas carburetor.

To achieve the above object, the utility model provides following technical solution: a kind of pure liquefied petroleum gas carburetor, packet Carburetor body, the trunnion with wasp waist shape on the carburetor body, the interior setting air throttle of trunnion and choke are included, in institute The carburetor body lower end stated is equipped with installing pipe, and the centre most narrow portion position of the installing pipe and the trunnion communicates, in the peace Tubulature lower end is plugged with pipe fitting, is equipped with nozzle in the upper end of the installing pipe, the outlet port of the nozzle is equipped with elasticity The pressurized ring of material, with the pressurized hole of taper on the pressurized ring, the tip setting of the pressurized hole is in outlet and towards larynx Tube cavity is equipped with recessing groove corresponding with the pressurized hole on the top of the pressurized ring, is made by the recessing groove described The pore wall thickness of pressurized hole controls between 0.8-1.5mm.

The material of the pressurized ring is rubber or elastoplastic.

This structure of the utility model, oil liquefied gas are connect by tracheae with pipe fitting, and are entered in installing pipe, by Flat nozzle is installed in the upper port of installing pipe, the outlet port of nozzle is equipped with the pressurized ring of elastic material, so that pure liquefaction stone Oil gas gathers pressurization in installing pipe, and is injected into trunnion by the pressurized hole of pressurized ring, and pressurized hole has certain wall thickness, So that the telescopic adjustment that pressurized hole can be open according to the air pressure of pure liquefied petroleum gas and the negative pressure of engine, it in this way can root The amount of injection is adjusted in due course according to the needs of engine, is improved pure liquefied petroleum gas injection efficiency and utilization rate, is just reached in this way Technical effect simple and reliable for structure and high-efficient.

The utility model is further described with reference to the accompanying drawings and detailed description.

Detailed description of the invention

Fig. 1 is the section view of specific embodiment of the present invention；

Fig. 2 is the enlarged drawing of A in Fig. 1.

Specific embodiment

The utility model is specifically described below by embodiment.

As shown in Figure 1 and Figure 2, present embodiment discloses a kind of pure liquefied petroleum gas carburetors, including carburetor body 1, change With the trunnion 2 of wasp waist shape, the interior setting air throttle 3 of trunnion 2 and choke 4 on oily device ontology 1, set in 1 lower end of carburetor body There is installing pipe 11, which communicates with the centre of trunnion 2 most narrow portion position, it is plugged with pipe fitting 5 in 11 lower end of installing pipe, The upper end of installing pipe 11 is equipped with nozzle 6, and the outlet port of nozzle 6 is equipped with the pressurized ring 7 of elastic material, has on pressurized ring 7 The pressurized hole 71 of taper, the tip setting of the pressurized hole 71 are set on the top of pressurized ring 7 in outlet and towards 2 inner cavity of trunnion There is recessing groove 72 corresponding with pressurized hole 71, controls the pore wall thickness of pressurized hole 71 in 0.8- by the recessing groove 72 Between 1.5mm, wherein the material of pressurized ring 7 is rubber or elastoplastic.

Through the above technical solutions, oil liquefied gas is connect by tracheae with pipe fitting 5, and is entered in installing pipe 11, by Flat nozzle 6 is installed in the upper port of installing pipe 11, the outlet port of nozzle 6 is equipped with the pressurized ring 7 of elastic material, so that pure liquid Liquefied oil gas gathers pressurization in installing pipe 11, and is injected into trunnion 2 by the pressurized hole 71 of pressurized ring 7, and pressurized hole 71 has There is certain wall thickness, so that pressurized hole 71 can be stretched according to what the air pressure of pure liquefied petroleum gas and the negative pressure of engine were open Contracting is adjusted, and can be adjusted in due course the amount of injection according to the needs of engine in this way, be improved pure liquefied petroleum gas injection efficiency and benefit With rate, technical effect simple and reliable for structure and high-efficient is just reached in this way.
