Embodiment
Below in conjunction with accompanying drawing, structural principle of the present invention and working principle are described in detail:
Be the structural representation of one embodiment of the invention see Fig. 4-6, Fig. 4, Fig. 5 is the C-C sectional view of Fig. 4, and Fig. 6 is the D-D sectional view of Fig. 4.Carburetor of the present invention, comprises body 1 and oily architecture 2, because the structure of these other parts of Carburetor, function and working principle etc. are more ripe prior art, therefore do not repeat at this.Only oily architecture 2 of the present invention is described in detail below.
It is 21 and main oil system 22 that You Xi mechanism 2 of the present invention comprises the oil-feed be arranged in described body 1, described main oil system 22 comprises main jet 221, main jet pipe 222, suction port 223, mixing chamber 224, closure 225, primary air metering-orifice 226 and primary air inclined hole 227, in the main oil well 3 that described main jet 221 and main jet pipe 222 are arranged on described Carburetor and the end of described main jet pipe 222 is positioned at described mixing chamber 224, described suction port 223 is communicated with described mixing chamber 224 and space outerpace respectively, described closure 225 is arranged in described mixing chamber 224, described primary air inclined hole 227 is communicated with described primary air metering-orifice 226 and main oil well 3 respectively.Wherein, the hole that primary air metering-orifice 226 is communicated with main oil well 3 is primary air inclined hole 227, and namely its function plays connection, makes air enter main oil well 3 by primary air metering-orifice 226.The end of described primary air inclined hole 227 is positioned at the top of described main oil well 3 and is oppositely arranged with described main jet pipe 222.
In the present embodiment, described oil-feed is 21 comprise oil inlet pipe 211, float chamber 212, float 213 and needle-valve 214, the body 1 that described oil inlet pipe 211 is arranged on described Carburetor is communicated with described float chamber 212, and described float 213 and needle-valve 214 are separately positioned in described float chamber 212.
See Fig. 6, in the present embodiment, this oily architecture 2 also can comprise oil drainage structure 23, and described oil drainage structure 23 is arranged on the bottom of described float chamber 212.In addition, this oily architecture 2 also can comprise plugging structure 24, and described plugging structure 24 is arranged on the bottom of described main oil well 3.
Visible, compared with prior art, Carburetor of the present invention only has a main oil system 22, without idling oil system.Decrease idle metering jet, idle adjusting screw, idling air jet, and idle fuel way, idling oil output hole and transition oil outlet processing.
Idling oil system 300(in the Carburetor of prior art is see Fig. 3), when idling and Smaller load, its process is as follows: fuel oil enters idle metering jet 301 by idle fuel way 306, air enters idle metering jet 301 by idling air jet 302, fuel oil foam is formed when fuel oil and air pass through idle metering jet 301, from idling oil output hole 303 and transition oil outlet 305 sucking-off, flow to cylinder with the air atomizing sucked from suction port 405.Meanwhile, fuel oil enters main jet pipe 403 by main jet 401, air enters main jet pipe 403 by primary air metering-orifice 402, fuel oil is made to form fuel oil foam in main jet pipe 403, when idling and Smaller load, there is small part fuel oil foam from the sucking-off of main jet pipe 403 mouth of pipe, enter mixing chamber 406 and participate in being atomized together with the air sucked from suction port 405, and flow direction engine cylinder.In entering, high-load operation time, main oil system 400 becomes main oil supply system gradually, and idling oil system 300 reduces fuel feeding, even fuel cut-off gradually.And Carburetor of the present invention is when engine idle and light running, mixed gas is formed and flow direction engine cylinder at mixing chamber 224 by main jet 221, main jet pipe 222, primary air metering-orifice 226 and suction port 223.In, high-load operation time be also like this.Namely Carburetor of the present invention is when motor is in the running of any operating mode, and mixed gas is all formed and flow direction engine cylinder at mixing chamber 224 by main jet 221, main jet pipe 222, primary air metering-orifice 226 and suction port 223.
Carburetor specific works process of the present invention following (see Fig. 4): during engine operation, fuel oil enters main jet pipe 222 by main jet 221, air enters main jet pipe 222 by primary air metering-orifice 226, fuel oil is made to form fuel oil foam in main jet pipe 222, during engine operation by fuel oil foam from the sucking-off of main jet pipe 222 mouth of pipe, enter mixing chamber 224 to be fully atomized together with the air sucked from suction port 223, and flow direction engine cylinder.This Carburetor engine idle and by idling to little, in, high-load operation time provide mixed gas by main oil system 22.The Carburetor of prior art, when engine idle and light running, forms mixed gas mainly through idle fuel way and idling air jet, through idling oil output hole and the ejection of transition oil outlet.Within the engine, high-load operation time, mixed gas by main jet 221, main jet pipe 222, primary air metering-orifice 226 and suction port 223 mixing chamber 224 formed and flow direction engine cylinder.
Therefore, the Carburetor of prior art be by idling oil be 300 and the co-ordination of main oil system 400 provide mixed gas for motor, need to control well above-mentioned two oil system guarantee engine stabilizer work, complex structure, produces wayward simultaneously; And Carburetor of the present invention only has a main oil system 22, no matter which kind of operating mode motor is in, mixed gas is provided by this main oil system 22, only need to control well this main oil system 22, such as, by reducing upper row's cross-drilled hole and the trunnion 228 of main jet pipe 222, making main oil system 22 realize the demand of idling and Smaller load fuel feeding in advance, thus making this main oil system 22 meet the service condition of motor.According to different motors, the operation demand of Under Different Work Condition of Engine can be met by the angle of the size of adjustment solar term aperture of door, throttle blade, main jet 221, main jet pipe 222 and primary air metering-orifice 226 etc.Avoid the co-ordination between two oil systems, only need the fuel oil controlled well needed for each operating mode in this main oil system 22 to supply, the accurate control of each operating mode can be realized very simply.Therefore structure is simple, and cost is low, good product consistency, easy to control; Reduce due to labyrinth cause producing in scattered error, the accurate control of each operating mode can be realized, finally improve the stability of motor, the pollution to environment when decreasing engine operation.
Certainly; the present invention also can have other various embodiments; when not deviating from the present invention's spirit and essence thereof; those of ordinary skill in the art are when making various corresponding change and distortion according to the present invention, but these change accordingly and are out of shape the protection domain that all should belong to the claim appended by the present invention.
