Abstract
The utility model relates to a motorbike carburetor, in particular to a motorbike carburetor with a multilevel foam pipe. The motorbike carburetor comprises a main air capacity hole, the foam pipe, a main oil mass hole, a main oil well of a main body, a main oil spraying pipe and a throttling valve; the main air capacity hole and the main body are riveted at the forefront of the carburetor in an interference fit manner, the main oil spraying pipe is positioned in the main oil well of the main body, and locked and compressed through the multilevel foam pipe; the main oil mass hole is locked at the tail end of the multilevel foam pipe through threads, and the multilevel foam pipe has two diameters including a smaller diameter of the upper part and a larger diameter of the lower part. When in low speed, the diameter of the upper part of the multilevel foam pipe is smaller, and the peripheral gaps of the multilevel foam pipe and the main oil well are larger, so that the resistance force can not be increased in the low speed. When in middle high speed, the diameter of the lower part of the multilevel foam pipe is larger, and the peripheral gaps of the multilevel foam pipe and the main oil well are smaller, so that the flow speed of air is accelerated, the combustible mixture gas is sufficiently atomized, and the combustion of an engine is more thorough, thereby achieving the purpose of saving energy and reducing waste gas.
Description
Technical field
The utility model relates to motorcycle carburetor, particularly a kind of motorcycle carburetor with multistage foam tube.
Background technique
Motorcycle carburetor when proper functioning, air mixed by a certain percentage with fuel oil and atomize after offer engine combustion, its fogging degree is directly connected to the effect and the speed of engine combustion, it is even more to atomize, atomizing particle is more little, its burning will be abundant more complete more, its power performance is perfect more, and exhaust gas discharged also can reduce relatively.
The suction cylinder burnt after the working principle of motorcycle carburetor all relied on negative pressure that the to-and-fro motion of engine piston produces with fuel oil and air mixing.The quantity of its suction fuel oil and the atomizing effect of mixed gas directly determine the performance of oil consumption, toxic emission and the performance of motor.The foam tube of common Carburetor has only a diameter, it and main oil well peripheral clearance are fixed, such structure is the intake resistance of air when reducing low speed, but bring unfavorable factor for high speed (cruising state just), because the excesssive gap between foam tube and the main oil well, can cause air to reduce, the stroke speed of combustion oil is slowed down and influenced the atomizing of inflammable mixture in main oil well and foam tube the inside flowing velocity.
The model utility content
The purpose of this utility model is to provide a kind of motorcycle carburetor with multistage foam tube, the foam tube that mainly solves existing Carburetor has only a diameter and the problem of the atomization badness that brings, because the excesssive gap between foam tube and the main oil well, can cause air to reduce, the stroke speed of combustion oil is slowed down and influenced the inflammable mixture atomizing in main oil well and foam tube the inside flowing velocity.
For realizing above-mentioned model utility purpose, the technical solution of the utility model is:
A kind of motorcycle carburetor with multistage foam tube, it is made up of primary air metering-orifice, multistage foam tube, main oil mass hole, main body master's oil well, main jet oil pipe, throttle valve; It is characterized in that: this primary air metering-orifice and the riveting of main body interference fit at Carburetor foremost, the main jet oil pipe is placed in the main body master oil well and by multistage foam tube locking and compress the main jet oil pipe; At multistage foam tube tail end, this multistage foam tube has two diameters by screw fastening in main oil mass hole, and top is less, and the bottom is bigger.
Described motorcycle carburetor with multistage foam tube is characterized in that: main oil mass hole by screw fastening at multistage foam tube tail end.
Described motorcycle carburetor with multistage foam tube is characterized in that: this main jet oil pipe is pressed on main body master oil well upper end by multistage foam tube.
By said structure, the utility model has the advantages that:
The multistage foam tube that the utility model Carburetor has has two diameters, and top is less, and the bottom is bigger.Because multistage foam tube top is less, multistage foam tube and main oil well peripheral clearance are bigger, the intake resistance in the time of can not increasing low speed when low speed.Multistage foam tube bottom is bigger when high speed, and multistage foam tube and main oil well peripheral clearance are less, and the flowing velocity of air is accelerated, and more abundant to the atomizing of inflammable mixture, engine combustion is more complete, has reached purpose energy-conservation and reduction waste gas.

Fig. 2 is the structural representation of multistage foam tube in the utility model.
Fig. 3 is an A-A sectional view among Fig. 2.
Fig. 4 is a B-B sectional view among Fig. 2.
Embodiment
See also Fig. 1-4, the utility model provides a kind of motorcycle carburetor with multistage foam tube.As shown in the figure: it is made up of primary air metering-orifice 1, multistage foam tube 2, main oil mass hole 3, main body master's oil well 4/ main jet oil pipe 5, throttle valve 6 etc.Primary air metering-orifice 1 and the riveting of main body interference fit are used for controlling the air quantity that enters multistage foam tube 2 at Carburetor foremost; Main jet oil pipe 5 is placed in the main body master oil well 4, locks and compress main jet oil pipe 5 by multistage foam tube; Main oil mass hole 3 on multistage foam tube 2, is used for controlling the amount of fuel that enters in the multistage foam tube 2 by screw fastening.
Motorcycle engine is when work, and air enters by primary air metering-orifice 1 in the middle of the main body master oil well 4, and fuel oil enters in the multistage foam tube 2 by main oil mass hole 3.
Vehicle is when cruising, the to-and-fro motion of engine piston produces pull of vacuum, with fuel oil and Air mixing gas from 5 sucking-offs of main jet oil pipe. because multistage foam tube bottom big (as Fig. 4), annular gaps D between multistage foam tube 2 and the main body master oil well 4 is diminished, like this under the situation of identical air mass flow, air flow velocity in main body master oil well 4 and multistage foam tube 2 of coming in from air jet 1 increases, the fuel particles striking velocity is accelerated, thereby reach fuel particles is thoroughly smashed, reach the effect of further atomizing.
Motor is at idling and low speed the time, engine speed is not very high, and the obstruction of throttle valve 6 is so much when amount of air drawn does not have proper functioning in addition, the negative pressure that inhaled air produces is not enough to mixed gas sucking-off from main jet oil pipe 5, will reduce the resistance of air in flowing this moment as far as possible.Therefore multistage foam tube 2 upper design get smaller, big slightly during than proper functioning with body peripheral edge clearance C (as Fig. 3), thus resistance of air compare less, the atomizing effect that burns in the time of can not influencing idling and low speed.
The above only is the actual example of the utility model in we produce, and is not to be used for limiting practical range of the present utility model.The i.e. all equivalences of doing according to the content of the utility model claim of this model utility change and modify, and all should be technology category of the present utility model.
