Description
This model utility is applicable to the Carburetor fuel-economizing, reduces exhaust emission pollution.Be specially adapted to the BJH201 Carburetor.
Mostly adopt in the world at present to delay the variation that the carburetor throttle closing velocity is controlled degree of vacuum in the suction tude, it can only save oil plant on a small quantity, but remains in unfavorable factor.1, it can not improve the braking ability of motor; 2, can make various moving elements increase wearing and tearing.In addition, do not see use at home and abroad as yet about the adjustable air metering-orifice, use nonadjustable air jet, the mixed gas oil-containing is denseer during middle or small load, the waste oil plant, and exhaust emission pollution is heavier.
The purpose of this model utility is to design a kind of saving oil plant for overcoming above deficiency, increase safety, and can reduce exhaust emission pollution, prolongs the motor Carburetor gasoline-saving device in working life.
Important technology scheme of the present utility model: be on the main oil supplying device of former BJH201 Carburetor, to change original air jet into the adjustable air metering-orifice, in former idling device, set up the forced idling enriching device.(it comprises vacuum, contact switch and idling economizer valve).
The concrete structure of this model utility in conjunction with the accompanying drawings 1,2.Be described below: adjustable air metering-orifice such as Fig. 1, adjust valve handle (8) upper end and protruding fast contact of accelerating pump pull bar, the lower end is fixed on to be adjusted on the valve rod (6), adjust valve rod (6) one ends and be carved with the rectangle breach, and enter the momentum hole (5) on the momentum hole body (4), the rectangular breach of adjusting on the valve rod (6) is corresponding with foam tube (7), and mixed gas enters small venturi (2) and middle trunnion (1) by trunnion oil duct (3), enters cylinder barrel through the intake and exhaust menifold again.Concrete action is as follows: when travelling, depress accelerator pedal of automobile, accelerating pump pull bar projection touches adjustment valve handle (8) rotates adjustment valve rod (6), the rectangular breach of adjusting corresponding foam tube (7) on the valve rod is also along with rotation, make the rectangular breach of adjusting on the valve rod (6) corresponding with the momentum hole (5) on the momentum hole body (4), the air inlet amount is ascending, and the oil content in the mixed gas from thick to thin, when engine power reach the highest after, the air inlet amount remains unchanged.
Forced idling enriching device such as Fig. 2, the forced idling enriching device is made up of vacuum (16), contact switch (20), idling economizer valve (9).When main chamber closure (19) when closing rapidly, the degree of vacuum of main chamber closure (19) below is very high, at this moment whole system is started working, its process is: vacuum gas is inhaled vacuum diaphragm (14) moving through vacuum way (17), idling economizer valve push rod (10) is promoted forward through true point (13) the pulling fuel-efficient rocking arm of vacuum (12) by vacuum pull bar (18), idle fuel way (23) is closed, idle jet (11) stop fuel feeding, the work of whole idle system system stop, simultaneously, the contact switch (20) that the fuel-efficient rocking arm of vacuum connects a terminal contacts distributor (21) the other end contact connection ignition switch (22) again separates, the igniting low-voltage circuit is disconnected, just stop burning of the work of spark plug stop, motor.
When the degree of vacuum of main chamber closure (19) below is reduced to a certain degree, because degree of vacuum is lower, vacuum diaphragm (14), vacuum pull bar (18), the fuel-efficient rocking arm of vacuum (12) are got back to original position under the effect of vacuum spring (15), idling economizer valve push rod (10) is got back to original position under the effect of idling economizer valve return spring (24), idle fuel way (23) just begins fuel feeding, contact switch (20) is connected the igniting low-voltage circuit simultaneously, and motor recovers proper functioning.This model utility has following advantage: 1, fuel saving 2, reduce exhaust emission pollution 3, strengthen traffic safety 4, prolong motor description of drawings in working life: accompanying drawing 1, adjustable air metering-orifice structural representation Fig. 1, middle trunnion 2, small venturi 3, trunnion oil duct 4, momentum hole body 5, momentum hole 6, adjust valve rod 7, foam tube 8, adjust valve handle accompanying drawing 2, forced idling enriching device structural representation Fig. 9, idling economizer valve 10, idling economizer valve push rod 11, idle jet 12, vacuum is fuel-efficient rocking arm 13, fulcrum 14, vacuum diaphragm 15, vacuum spring 16, vacuum 17, vacuum way 18, vacuum pull bar 19, main chamber closure 20, contact switch 21, distributor 22, ignition switch 23, idle fuel way 24, idling economizer valve return spring
Claims (3)
1, a kind of Carburetor gasoline-saving device: if carburetor main is made up of main oil supplying device, idling device, enrichment-system, accelerating unit, starting arrangement, it is characterized in that: change the air jet on the main oil supplying device into the adjustable air metering-orifice, in the idling device, set up the forced idling enriching device.
2, according to the said Carburetor gasoline-saving device of claim 1, it is characterized in that: the adjustable air metering-orifice is to adjust valve handle (8) upper end to contact with accelerating pump pull bar projection, the lower end is fixed on to be adjusted on the valve rod (6), adjust valve rod (6) one ends and be carved with the rectangular breach, and enter the momentum hole (5) on the momentum hole body (4), the rectangular breach of adjusting on the valve rod (6) is corresponding with foam tube (7), mixed gas enters small venturi (2) and middle trunnion (1) by trunnion oil duct (3), enters cylinder barrel by the intake and exhaust menifold again.
3, according to claim 1,2, said Carburetor gasoline-saving device, it is characterized in that: the forced idling enriching device is by vacuum (16), contact switch (20), idling economizer valve (9) is formed, concrete structure is as follows: vacuum gas is inhaled vacuum diaphragm (14) moving through vacuum way (17), vacuum pull bar (18) promotes idling economizer valve push rod (10) forward through fulcrum (13) the pulling fuel-efficient rocking arm of vacuum (12), idle fuel way (23) is closed, idle jet (11) stop fuel feeding, the fuel-efficient rocking arm of vacuum (12) separates the contact switch (20) that a terminal contacts connects distributor (21) the other end contact connection ignition switch (22) simultaneously, igniting is that low-voltage circuit disconnects, when degree of vacuum is reduced to a certain degree, vacuum diaphragm (14), vacuum pull bar (18), vacuum is fuel-efficient shakes (12) arm get back to original position under vacuum spring (15) effect, idling economizer valve push rod (10) is got back to original position under the effect of idling economizer valve return spring (24), the beginning fuel feeding, contact switch (20) is connected the igniting low-voltage circuit simultaneously, and motor recovers proper functioning.
