The adjusting screw 42 of aperture, the adjusting screw 42 are mounted on carburetor body 1, are arranged with spring in adjusting screw 42.
The operation method of the present embodiment, comprising the following steps:
(1) fuel feeding: when engine operation, speed air flow is accelerated to generate vacuum in inlet channel 16, through being set to
Negative pressure air channel 15 in carburetor body 1 makes the side of a diaphragm 24 by suction function, and what diaphragm 24 was equipped with is used for
The first movable valve 241 and the second movable valve 242 for blocking oilhole are mobile by negative pressure, so that oilhole is opened, fuel flow communication；
(2) secondary fuel feeding: when engine operation, the fuel oil of oil pocket 11 is sucked into inlet channel 16, is made in oil pocket 11
Vacuum is generated, the negative pressure bullet film 25 on oil pocket 11 is driven to move to 11 side of oil pocket, what is be arranged in oil pocket 11 is used to stop fuel oil
Needle valve type oil-inlet mechanism 7 into oil pocket is triggered, and fuel oil is made to enter oil pocket 11；
(3) high speed oil spout: when high engine speeds operate, speed air flow is faster in inlet channel 16, in oil pocket 11
Vacuum degree is bigger, and more fuel oils is ejected from nozzle, is dispersed into mist of oil through swiftly flowing air, finally flows into engine
Inside burn；
(4) idling oil spout: when engine idling operation, speed air flow is slow in inlet channel 16, in oil pocket 11 compared with
Small vacuum degree drives less fuel oil to spray from oil pocket 11 through nozzle, and the air through flowing is dispersed into mist of oil, finally flows into hair
It burns in motivation.
In the present embodiment, the amount of fuel size of demand can be adjusted according to generated vacuum degree size, demand combustion
The flowing velocity of air is bigger when oil mass is bigger, in inlet channel 16, vacuum degree is bigger, the pressure that 24 upper and lower sides of diaphragm are subject to
The pressure difference that power is poor, 25 upper and lower sides of negative pressure bullet film are subject to is bigger, and the first movable valve 241 and the second movable valve 242 are mobile
Amplitude increase, the fuel oil for flowing to inner housing 21 from outer housing 22 just increases；Meanwhile the amplitude of the movement of negative pressure bullet film 25 also adds
Greatly, the mobile distance for driving needle 72 to move up of rocker arm 71 increases, and oil inlet quantity is just more in oil pocket 11, main burner 164, the spray of second level idling
The oil mass that mouth 163 and level-one idling jet 162 spray is consequently increased.
As shown in figure 4, in the present embodiment, adjusting main burner 164, second level idling jet 163 and level-one idling jet 162
The oil mass of ejection can adjust screw 5 by high speed and low speed adjusts screw 3, and high speed adjusts screw 5 and low speed adjusts screw 3
The tapered configuration of end setting, cooperation adjust oil mass with the gap that oil duct is formed.
Specific implementation process: when engine operation, fuel oil O is by feed cover 23 to oil suction chamber 221, air in inlet channel 16
Flowing velocity is accelerated, and aspirates air in negative pressure cavity 211 through negative pressure air channel 15, generates negative pressure cavity 211 lower than diaphragm 24
The pressure of the other side, diaphragm 24 is mobile to 211 direction of negative pressure cavity under the action of negative pressure, and valve is opened, and fuel oil O is through oil inlet duct
2211- the first oilhole 225- the first oil groove 214- the second oilhole 223- fuel feed hole 2221- shoe cream room 11- oil outlet 2222- third
The second oil groove of oilhole 224- 215, eventually flows into oil circuit；Needle 72 blocks hydraulic fluid port at this time, when fuel oil is sprayed in oil pocket 11
Go out, pressure reduces in oil pocket 11, and the air pressure of the top of negative pressure bullet film 25 through pressure hole 2131 communicate with the outside world to keep with
Atmospheric pressure is identical, and 25 upper and lower of negative pressure bullet film generates pressure difference, moves down negative pressure bullet film 25, and jacking block 251 is driven to contact
71 one end of rocker arm is pushed on rocker arm 71, the needle 72 of 71 other end of rocker arm moves up, and hydraulic fluid port is opened, and fuel oil flows to oil pocket 11
It is interior.
When engine start, choke is closed or aperture is smaller, and the gas concentration in inlet channel 16 is larger, ensure that
The requirement of the high-concentration oil vapor of engine start, when high engine speeds operate, fuel oil in oil pocket 11 is from main burner 164, second level
Idling jet 163 and level-one idling jet 162 spray, and aditus laryngis of the air G through inlet channel 16, flowing velocity is accelerated, and will spray
Fuel oil be dispersed into air-fuel mixture mist M, finally flow into engine and burn；When engine idling operation, in oil pocket 11
Fuel oil O is sprayed from second level idling jet 163 and level-one idling jet 162, and the air of inlet channel 16 passes through trunnion 161, flowing
Speed is accelerated, and the fuel oil of ejection is dispersed into air-fuel mixture mist M, finally flows into engine and burns, when engine needs
When lower running speed, choke door-plate 4, throttle plate 6 can be closed, less fuel oil O from the outside of throttle plate 6 one
Grade idling jet 162 sprays, and provides less air-fuel mixture mist M.
