Inlet end, trunnion and outlet side, the air throttle are set in the outlet side, the opening angle for controlling carburetion channel；
The different location of the inner wall of the trunnion is provided with more than two nozzle openings, the nozzle opening by pipeline and
The proportion magnetic valve is connected to the float chamber, one end of the proportion magnetic valve and the float chamber and carburetion channel
Inlet end is connected to, and the other end of proportion magnetic valve is connected to the nozzle opening.
Further, the nozzle opening is along the circumferential direction uniformly distributed on the inner wall of the trunnion.
Further, the air throttle is butterfly valve.
Further, the inner wall of the float chamber is provided with oil inlet, and the oil inlet is provided with needle-valve.
Further, the nozzle opening is distributed in the surface of a circulating line, and the circulating line passes through pipeline and institute
It states proportion magnetic valve and is connected to the float chamber.
It is different from the prior art, the advantages of above-mentioned technical proposal is, proportion magnetic valve is provided in carburetor, is passed through
The size of coil current or the size of electromagnetic force change valve opening, and between valve opening and coil current are ideal line
Sexual intercourse, therefore, by proportion magnetic valve can accurately controlling opening of valve size, gasoline under the action of vacuum degree and
It is quickly and uniformly sprayed from nozzle opening under the adjusting of proportion magnetic valve, keeps gasoline atomizing more uniform, improved efficiency of combustion, reach
To energy-efficient effect.

Specific implementation mode
For the technology contents of technical solution, construction feature, the objects and the effects are described in detail, below in conjunction with specific reality
It applies example and attached drawing is coordinated to be explained in detail.
It please refers to Fig.1 and Fig. 2, present embodiments provides a kind of multiple spot jet carburetor, including carburetor body and set
The proportion magnetic valve 1 and air throttle 2 being placed in carburetor body.The size or electricity that the proportion magnetic valve 1 passes through coil current
The size of magnetic force changes valve opening, and between valve opening and coil current is ideal linear relationship, therefore, works as ratio
When solenoid valve 1 receives throttle signal, can accurately controlling opening of valve size.
The carburetor body includes carburetion channel and float chamber 3, and the carburetion channel is wrapped successively by one end to the other end
Inlet end 4, trunnion 5 and outlet side 6 are included, the air throttle is set in the outlet side 6, the unlatching for controlling carburetion channel
Angle；The different location of the inner wall of the trunnion 5 is provided with more than two nozzle openings 51, the nozzle opening 51 by pipeline with
And the proportion magnetic valve 1 is connected to the float chamber 3, one end of the proportion magnetic valve 1 and float Room 3 and carburetion
The inlet end 4 in channel is connected to, and the other end of proportion magnetic valve 1 is connected to the nozzle opening 51, and the nozzle opening 51 is circumferentially square
To being uniformly distributed on the inner wall of the trunnion 5, it is preferred that the nozzle opening 51 is distributed in the surface of a circulating line 52,
The circulating line 52 is connected to the float chamber 3 by pipeline and the proportion magnetic valve 1.The float chamber 3 is used for storing up
Deposit by petrol pump conveying Lai gasoline, to ensure the supply of fuel oil.The inlet end 4 is used for supplying air.The trunnion 5 is wherein
Between throat sectional area it is minimum, one end of the trunnion 5 is connected to engine cylinder head, when the engine starts, air sucking,
Opening throttle 2, speed is maximum when the air-flow of inflow passes through throat, and static pressure is minimum, therefore the pressure in trunnion 5 is less than greatly
Atmospheric pressure, that is to say, that pressure difference is produced between 5 throat of trunnion and float chamber 3, the bigger vacuum degree of pressure difference is bigger；Gasoline
It is equably sprayed under the action of vacuum degree and from nozzle opening 51 under the adjusting of proportion magnetic valve 1, the air stream of 5 throat of trunnion
Speed is about 25 times of gasoline flow velocity, therefore the gasoline that nozzle opening 51 equably sprays is broken up by the air stream of high speed, is formed
The mist particles to differ in size.The outlet side 6 is that mist particles and air mixture are passed through engine by air inlet pipe
Cylinder.The nozzle opening 51 can quickly and uniformly spray gasoline under the adjusting of proportion magnetic valve 1, make gasoline atomizing more
Uniformly, efficiency of combustion is improved, energy-efficient effect is reached.
The air throttle 2 is butterfly valve, is that its is simple in structure using butterfly valve, and whens opening and closing facilitates rapid, laborsaving, stream
Body resistance is small, and regulation performance is good, and under low pressure, good sealing may be implemented.In other embodiments, ball valve can also be applied
Deng.
The inner wall of the float chamber 3 is provided with oil inlet 31, and the oil inlet 31 is provided with needle-valve 32.The oil inlet 31
For supplying gasoline, the needle-valve 32 is control gasoline input quantity and float chamber 3 is made to keep certain fuel head.Work as float chamber
When 3 pastas reach specified altitude, the linking arm on float in float chamber 3 up pushes away needle-valve 32, stoppers in oil inlet 31
Distal opening, gasoline just cannot continue to flow into float chamber 3；When gasoline consumption, 3 pasta of float chamber declines, the linking arm on float
It falls, needle-valve 32 reopens, and gasoline enters in float chamber 3 again, is opened in the end of oil inlet 31 until the rising of needle-valve 32 is stoppered
Mouthful.
It should be noted that although the various embodiments described above have been described herein, it is not intended to limit
The scope of patent protection of the utility model.Therefore, the innovative idea based on the utility model carries out embodiment described herein
Change and modification or equivalent structure or equivalent flow shift made based on the specification and figures of the utility model, directly
Or above technical scheme is used in other related technical areas indirectly, it is included in the protection model of the utility model patent
Within enclosing.
