Description

The automobile and motorcycle high efficient oil saving device

The utility model relates to a kind of oil-saving purifier, particularly a kind of automobile and motorcycle deacceleration fuel shut-off device.

In the running process of automobile, motorcycle, it is about 30% that forced idling accounts for whole running process, thereby caused the waste of fuel.For this reason, people have invented multiple fuel-saving technique and device, " gasoline automobile gasoline-saving device " as Chinese patent " CN 2100495U ", obtained certain oil-saving effect, but the mechanical structure of this fuel economizer and control circuit are all complicated, and this is all unfavorable to processing, install, debugging, and easily produces fault, versatility is not good enough, is difficult to apply; Also have a kind of fuel economizer of U. S. Patent " 3,693,650 ", simple in structure, can directly reduce oil inlet quantity, keep optimum air fuel oil ratio preferably, but it can influence the starting performance of motor simultaneously, the particularly cold state of incompatibility motor starting.

The purpose of this utility model is at the problems referred to above, provide a kind of simple in structure, do not need circuit control, can make motor car engine under various working condition requirements, particularly forced idling, can both keep optimum air fuel oil ratio, fuel saving ratio and thermal efficiency height, the fuel economizer of minimizing toxic emission.

The utility model is realized its purpose as follows: it comprises an inflator, its connection set is connected to the position between engine and carburetor closure bottom and suction tude pipe, link arm 8 communicates with resonant cavity 9, several ball valves 5 by supporting base 7 supportings are arranged in the passage 6 of resonant cavity 9 tops, and ball valve is attached to the lower end of the inlet hole 4 that communicates with air filtering core 3; It also has a control gear, there is vacuum chamber 17 the fuel economizer top, and movable valve core 14 1 ends are connected with the spring 15 that is positioned at vacuum chamber, inlet hole 4 is sealed in its bottom when spring is static upper end, vacuum chamber 17 bottoms also have diaphragm 13 around the valve core, and 17 of passage 6 and vacuum chambers communicate with air flue 2.

Compare with prior art, the utility model has the advantages that simple in structurely, cost is low, can guarantee that the fuel oil that enters cylinder fully burns, and reduces oil consumption, reduces deflagration phenomenon, and toxic emission is reduced, and does not lose the original maximum output of motor in fuel-economizing.

Embodiment further specifies the utility model below in conjunction with accompanying drawing.

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

End cap 16 of the present utility model, vacuum chamber 17, spring 15, valve core 14, diaphragm 13, air flue 2, inlet hole 4, ball valve 5, passage 6 and supporting base 7 etc. are in upper shell 1, end socket 10, resonant cavity 9, link arm 8 and seal ring 12 etc. are in lower shell body 11, between upper and lower casing with scyewed joint, the screw thread length of regulating between upper and lower casing can make ball valve 5 be close to inlet hole 4 lower ends, and keeps precompression to a certain degree.Spring 15 1 ends are fixed on the end cap 16.Air filtering core 3 can be one, also can be a plurality of.When fuel economizer is contained on the motorcycle, be connected to Carburetor valve bottom with connecting tube 18 and the joint 19 that is connected on the link arm 8; When being contained on the automobile, on joint 19, connecing piece 20 again and get final product.Upper and lower casing and ball valve all adopt the nonmetallic material manufacturing.

When static, inlet hole 4 upper and lower ends are closed by movable valve core 14 and ball valve 5 respectively.When motor is in starting state, the degree of vacuum of vacuum chamber 17 is low, be not enough to open valve core 14, fuel economizer is in full closing state, to guarantee the starting performance of motor, raising along with engine speed and running time, when degree of vacuum reached certain limit in the vacuum chamber, diaphragm 13 overcame the pressure of spring 15 under the effect of negative pressure, push valve core 14 open and open inlet hole 4 upper ends, make fuel economizer be in standby condition; During normal vehicle operation, the inflammable mixture that general Carburetor is supplied with is enough to keep optimal air fuel oil ratio, because of carburetor throttle bottom degree of vacuum less, ball valve 5 is in the state of closing inlet hole usually, when the operating mode of vehicle changes suddenly, as closure reduce, bring to a halt, when particularly the lower long slope engage a gear travels, motor is forced to run up, and is in forced idling mode.This moment, carburetor throttle bottom degree of vacuum improved, when reaching certain limit, under action of pressure, outside air is pushed ball valve 5 open, fresh air flows to passage 6 through filter core 3, inlet hole 4, air-flow is done rotation rapidly under the guiding of supporting base 7, by link arm 8, connecting tube 18, joint 19 or connect piece 20, enter the carburetor throttle bottom at last, reduced degree of vacuum like this, the idling speed fuel delivery of Carburetor is reduced or stop, and reduce that string on the cylinder machine oil consumes and the carbon deposit phenomenon of firing chamber.

When the power condition changing of motor is big, when degree of vacuum surpassed certain limit, ball valve can be compressed and produce lateral expansion, and aisle spare is diminished, and had limited the excessive of air and had replenished; Air-flow owing to viscous friction produces static, is negative polarity when flowing through the space of passage and ball valve, the fuel mixture body that this air-flow enters carburetor throttle bottom and positively charged meets, just mix with the fuel mixture body rapidly, form more fine liquid drops, promote the fuel oil active combustion; On the other hand, because the running of motor, ball valve also produces vibration along with air-flow, and air-flow forms strong pulsatile impact ripple under the effect of resonant cavity 9, make the more even mixing of fuel mixture body, has improved fogging degree, thereby improves the thermal efficiency of motor.

Under motor was in superelevation load running situation when quickening, surmounting front truck or climbing as starting, because of carburetor throttle is a full-gear, closure bottom degree of vacuum was low, and ball valve is closed inlet hole automatically, does not influence pick-up of engine.

The utility model shows through nearly ten thousand kilometers operation and actual measurement: adorned the same vehicle that vehicle behind this device is unkitted this device, simulation forced idling comparative trial fuel saving ratio reaches 22%, mountain highway driving comparative trial fuel saving ratio reaches 7.3%, Class II highway driving comparative trial fuel saving ratio reaches 9.1%, avenue driving comparative trial fuel saving ratio reaches 10.7～13.6%, HC purification ratio 55%, CO purification ratio 94%, and this device has kept the original maximum output of this car engine in fuel-economizing.
