The adjusting screw 42 of aperture, described adjusting screw 42 is arranged on carburetor body 1, and adjusting screw 42 is arranged with spring.
The operation method of the present embodiment, comprises the following steps:
(1) fuel feeding:Engine work when, in inlet channel 16 speed air flow accelerate produce vacuum, through located at
Negative pressure air passage 15 in carburetor body 1 makes the side of a diaphragm 24 be subject to suction function, and what diaphragm 24 was provided with is used for
First movable valve 241 of closure oilhole and the second movable valve 242 are moved by negative pressure, thus opening oilhole, fuel flow communication;
(2) secondary fuel feeding:During engine work, the fuel oil of oil pocket 11 is sucked in inlet channel 16, makes in oil pocket 11
Produce vacuum, drive the negative pressure bullet film 25 on oil pocket 11 to oil pocket 11 1 lateral movement, setting for stopping fuel oil in oil pocket 11
The needle valve type oil-inlet mechanism 7 entering oil pocket is triggered, and makes fuel oil enter oil pocket 11;
(3) high speed oil spout:During high engine speeds operating, in inlet channel 16, speed air flow is faster, in oil pocket 11
Vacuum is bigger, and more fuel oils are ejected from nozzle, is dispersed into mist of oil through swiftly flowing air, finally flows into engine
Inside burnt;
(4) idling oil spout:During engine idling operation, in inlet channel 16, speed air flow is slow, in oil pocket 11 relatively
Little vacuum drives less fuel oil to spray through nozzle from oil pocket 11, and the air through flowing is dispersed into mist of oil, finally flows into and sends out
Burnt in motivation.
In the present embodiment, the amount of fuel size of demand, can adjust according to produced vacuum size, and demand is fired
When oil mass is bigger, in inlet channel 16, the flowing velocity of air is bigger, vacuum is bigger, and what diaphragm 24 upper and lower sides were subject to presses
The pressure differential that power is poor, negative pressure bullet film 25 upper and lower sides are subject to is bigger, and the first movable valve 241 and the second movable valve 242 are mobile
Amplitude increase, the fuel oil flowing to inner housing 21 from shell body 22 just increases;Meanwhile, the amplitude of negative pressure bullet film 25 movement also adds
Greatly, rocking arm 71 is mobile drives the distance moved on needle 72 to increase, and in oil pocket 11, oil inlet quantity is just many, 164, two grades of idling sprays of main burner
The oil mass of mouth 163 and one-level idling jet 162 ejection is consequently increased.
As shown in figure 4, in the present embodiment, 164, two grades of idling jets 163 of main burner and one-level idling jet 162 are adjusted
The oil mass spraying can pass through high speed adjusting screw 5 and low speed adjusting screw 3, high speed adjusting screw 5 and low speed adjusting screw 3
The tapered configuration of end setting, the gap adjustment oil mass that cooperation is formed with oil duct.
Specific implementation process:During engine work, 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 passage 15, so that negative pressure cavity 211 is produced and is less than diaphragm 24
The pressure of opposite side, diaphragm 24 moves to negative pressure cavity 211 direction in the presence of negative pressure, and valve is opened, and fuel oil O is through oil-feed 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- the 3rd
Oilhole 224- the second oil groove 215, eventually flows in oil circuit;Now hydraulic fluid port is blocked by needle 72, when in oil pocket 11, fuel oil is injected
Go out, in oil pocket 11, pressure reduces, and the air pressure of negative pressure bullet film 25 top communicates with the external world through pressure hole 2131 thus keep and
Atmospheric pressure is identical, and negative pressure bullet film 25 upper and lower produces pressure differential, so that negative pressure bullet film 25 is moved down, and drives jacking block 251 to contact
On rocking arm 71, rocking arm 71 one end is pushed, the needle 72 of rocking arm 71 other end moves up, and hydraulic fluid port is opened, and fuel oil flows to oil pocket 11
Interior.
During engine start, choke close or aperture less, the gas concentration in inlet channel 16 larger it is ensured that
The requirement of the high-concentration oil vapor of engine start, during high engine speeds operating, the fuel oil in oil pocket 11 is from 164, two grades of main burner
Idling jet 163 and one-level idling jet 162 spray, the aditus laryngis through inlet channel 16 for the air G, and flowing velocity is accelerated, and will spray
Fuel oil be dispersed into air-fuel mixture mist M, finally flow in engine and burnt;During engine idling operation, in oil pocket 11
Fuel oil O sprays from two grades of idling jets 163 and one-level idling jet 162, and the air of inlet channel 16, through trunnion 161, flows
Speed is accelerated, and the fuel oil of ejection is dispersed into air-fuel mixture mist M, finally flows in engine and burnt, when engine needs
During lower running speed, choke door-plate 4, throttle plate 6 can be closed, less fuel oil O is from the one of throttle plate 6 outside
Level idling jet 162 sprays, and provides less air-fuel mixture mist M.
