Abstract

The utility model relates to a fuel-saving carburetor for a motorcycle, which is operated by that one carburetor is connected with two air cylinders and avoids the phenomenon that two carburetors use two throttle pull ropes to make the adjustment of free strokes not incompletely coincide and cause an engine to have unstable operation. The utility model can be modified on the original motorcycle, and compared with the original design, the consumed fuel of the modified motorcycle can be saved by more than 25% per 100 kilometers. The utility model has the advantages of low fabricating cost and convenient maintenance. Because the engine has stable operation, the combustion of the fuel is sufficient, the tail gas of the motorcycle is cleanly discharged and the city environment is beautified.

Description

Motorcycle fuel-economizing Carburetor

The utility model belongs to the fuel supplying device of vehicle in the communications and transportation, particularly relates to a kind of Carburetor of motorcycle fuel-economizing.

At present, on motorcycle adopt two Carburetors to come the supply engine cylinder operation, two Carburetors are with two throttle stay cords more, and that the free travel of two stay cords is regulated is impossible in full accord, will influence the motor bad Acceleration like this, power can not all be exported.Chinese patent CN2204252Y discloses a kind of " automobile fuel-economizing device ", and its structure is made up of float chamber, float, water chamber etc., and water chamber communicates with Carburetor suction port on the Carburetor connecting plate by outlet conduit and atomization conduit.

The purpose of this utility model is to improve a kind of motorcycle fuel-economizing Carburetor on original car.

The purpose of this utility model realizes by following technical solution.

A kind of motorcycle fuel-economizing Carburetor, turn to the solar term needle that the control valve steel cable of control is connected air throttle and air throttle below by the spring in the cover of plunger by motorcycle, air throttle is in the mixing chamber, its left side is air-strainer and air passageways, two cylinders that the left side connects for the mixed gas suction tude, main jet oil pipe and idling spray bar below air throttle, have been arranged side by side, its main jet oil pipe connects the main foaming pipe and the main jet of its lower end, the idling spray bar connects the idling foaming pipe and the idle adjusting screw of its lower end, they all are enclosed in the float chamber, also are provided with the fuel oil filler opening in float chamber.

The utility model is controlled two cylinder operation with a Carburetor, and can utilize original motorcycle to reequip, and it is more fuel-efficient more than 25% than former design to reach the per 100 km oil consumption; Changed because the difference of two Carburetors on adjusting makes two cylinder operation of motor more steady with a Carburetor job, effectively utilized the output power of motor; The manufacture cost of improved its gas handling system of motorcycle reduces, and it is more convenient to keep in repair; Because oil inflame is abundant, exhaust emissions is cleaner, and environmental hygiene is protected, and air purifies more.

Fig. 1 is a structural representation of the present utility model.

Below in conjunction with drawings and Examples, the utility model is described in further detail.

As shown in Figure 1, a kind of motorcycle fuel-economizing Carburetor, turn to the solar term needle 3 that the control valve steel cable 1 of control is connected air throttle 2 and air throttle below by the spring in the cover of plunger 15 by motorcycle, air throttle 2 is in the gas mixing chamber, its right side is air-strainer 14 and air passageways 4, the left side is two cylinders that mixed gas admission line 13 connects, main jet oil pipe 11 and idling spray bar 12 below air throttle 2, have been arranged side by side, its main jet oil pipe 11 connects the main foaming pipe 6 and the main jet 7 of its lower end, and idling spray bar 12 connects the idling foaming pipe 9 and the idle adjusting screw 10 of its lower end; They all are enclosed in the float chamber, also are provided with filler opening 5 in float chamber.Working principle of the present utility model is: when motor during at idle running, because air throttle 2 is almost completely fallen, near closed condition, air and idling foaming pipe 9 gasoline that enter that entered by air passageways 4 this moment, in foaming pipe 9, form foam and produce atomizing, become inflammable mixture, spray by suction tude and enter cylinder operation from spray bar 12, adjust idle adjusting screw 10, can change the concentration ratio of incendivity mixed gas; When motor is worked in middling speed, air throttle 2 is opened half approximately, thicker part part of solar term needle 3 is positioned at main jet oil pipe mouth, the discharge of restraining fuel oil, at this moment the air that is entered by the gasoline and the air passageways 4 of main jet 7 forms foam in main foaming pipe 6, produce the incendivity mixed gas, enter cylinder operation by suction tude 13 by 11 ejections of main jet oil pipe; When high engine speeds is worked, on continuing, air throttle 2 carries, because solar term needle 3 is tapers, so the section of main jet oil pipe increases, kept the spray volume of fuel oil, thereby made main jet oil pipe 11 spray inflammable mixture with the spray volume of maximum to mixing chamber, it is maximum that engine power reaches.
