Problems solved by technology

[0003] Since the amount of fuel dispensed at each moment is determined by the pressure drop at the throat relative to the reference pressure in the cavity, when the carburetor air filter becomes dirty, the fuel-air mixture ratio changes and becomes richer , while increasing the degree of pollution

Embodiment Construction

[0014] As mentioned earlier, from figure 1 It can be seen that there is a ventilation pipe (1) in the traditional carburetor, which is fixed in the base of the carburetor. In order to make the cavity communicate with the atmosphere forever, the ventilation pipe (1) extends into the fuel chamber through the hole (2) Inside, the ventilation pipe (1) communicates with the atmosphere through the hole (3).

[0015] exist figure 2 Can clearly see the improvement of the present invention in, comprise setting three-way pipe (4), make one end hole of three-way pipe (4) communicate with hole (3), the end hole (5) of three-way pipe (4) It is fixed in the mixed air channel (7) of the engine, the end hole (8) of the tee pipe (4) is fixed in the filter (9), and the air inlet (10) of the filter (9) is placed in the atmosphere.

[0016] And, if image 3 As shown, the air inlet (10) of the filter (9) is arranged at the air inlet (11) of the original carburetor air filter (6), which not on...

Abstract

The invention relates to the ventilating system of fuel cavity. Owing to connecting with the end opening of three-way pipe parked in the mixed gas channel and end opening in the cleaner, the free end opening of the traditional vent-pipe can not only make the fuel cavity get clean air at any time, but also let the air passing through the cleaner produce a pressure drop at the free end opening of the original vent-pipe. The pressure drop passes into the fuel cavity and cooperate with the fuel-supplying pressure caused by the venturi effect.

Description

Technical field [0001] The present invention relates to the improvement of the carburetor of the motorcycle, especially acting on the ventilation system of the oil chamber to achieve the necessary three effects, namely: on the one hand, reduce the pollutants in the whole working range of the engine; secondly, increase the engine power; finally, when the carburetor Maintain an independent correct fuel ratio even after the air filter becomes dirty. Background technique [0002] In addition to a series of parts that do not need to be described here, a motorcycle carburetor has a fuel supply chamber from which fuel is sucked out by the Venturi effect created by the entry of air. [0003] Since the amount of fuel dispensed at each moment is determined by the pressure drop at the throat relative to the reference pressure in the chamber, when the carburetor air filter becomes dirty, the fuel-air mixture ratio changes and becomes richer , and increase the degree of pollution. Con...
