Abstract
The utility model relates to an adjustable self-controlling forced idle speed fuel economizer which is matched with a carburetor for an engine of a gasoline car. The utility model is mainly characterized in that an adjustable self-controlling vacuum drum is additionally arranged between a lower seat of the carburetor and a suction manifold, and original idle speed screws are improved into adjustable self-controlling idle speed screws which can separably move. Under the combined action of the adjustable self-controlling vacuum drum and the adjustable self-controlling idle speed screws which can separably move, the influence of excessively high vacuum degrees can be eliminated, and a fuel-saving purpose is achieved. Therefore, the utility model has the advantages of simple and reasonable structure, convenient adjustment and use, low manufacture cost, high fuel-saving ratios, high safety, etc., and the utility model which can accommodate various car types is an ideal fuel-saving device.
Description
The utility model relate to a kind engineering machinery class with the matching used adjustable auto-controlled formula forced idling fuel-saving machine of gasoline vehicle engine Carburetor.
In the prior art, adopt to improve the gasoline car Carburetor to eliminate the forced idling phase influence of " crossing strong degree of vacuum ", cut off the idling fuel feeding, reach the fuel-economizing purpose, can reduce two classes substantially: a class is " closed ", and a class be " a disappointing formula ".Before the method that adopted be " blocking up ", therefore not only can not eliminate the forced idling phase influence of " crossing strong degree of vacuum " and save machine oil, increase Oil Consumption on the contrary, big to mechanical wear, especially the change that has the structure of former Carburetor, increased the operation piece in driving, engine acceleration has been impacted; And the latter's idling fuel economizer major part is contained in more than the idle jet, because the air inlet basal area of idling oil system has been fixed by designing requirement, be that the air inlet basal area is little, influence with auspicious can not the elimination " strong degree of vacuum excessively ", even be contained between carburetor throttle bottom and the inlet manifold, though can enlarge the air inlet basal area, but can not prevent " degree of vacuum " influence to idling oil system, " degree of vacuum " is since can go into cylinder to this class fuel economizer control valve door-inhale open air, equally also just have from idle fuel way and inhale the next pull of vacuum of oil down, thereby can not reach the purpose of saving whole forced idling oil consumption.
The purpose of this utility model is to improve at the above-mentioned deficiency that remains in the prior art a kind of simple and reasonable, adjustment is easy to use, cheap, applicability is strong, safe and reliable adjustable auto-controlled formula forced idling fuel-saving machine of design.
Technical solution of the present utility model is: set up a fuel-saving machine seat (also this fuel-saving machine seat not between following of Carburetor and inlet manifold, and directly at the closure bottom of following of Carburetor dress vacuum drums), an adjustable auto-controlled formula vacuum drums that is made of vacuum chamber, valve seat, sealing gasket, valve, valve spring, adjustment nut, retaining nut, valve pin, filter screen and screen cover is set on its boss with oblique through hole; Simultaneously, original fixed idling screw is improved the adjustable auto-controlled formula idling screw that is designed to adjust the separable activity that nut, syringe needle pin, needle guard spring, filter screen and screen cover constitute by needle guard, syringe needle, needle spring, syringe needle.This is auspicious, under the acting in conjunction of adjustable auto-controlled formula idling screw and adjustable auto-controlled formula vacuum drums, can eliminate the influence of " crossing strong degree of vacuum ", reaches the purpose of safe fuel-economizing.
Below in conjunction with accompanying drawing the utility model is further described.
Accompanying drawing 1 is a structural representation of the present utility model.
The utility model system by a fuel-saving machine seat (1) of between following of gasoline vehicle engine Carburetor and inlet manifold, setting up and its front portion on its boss, being provided with oblique through hole press fit in this oblique through hole by vacuum chamber (2), valve seat (3), sealing gasket (4), valve (5), valve spring (6), adjust nut (7), retaining nut (8), valve pin (9), filter screen (10) improves with the adjustable auto-controlled formula vacuum drums of screen cover (11) formation and with original fixed idling screw and is designed to by needle guard (12), syringe needle (13), needle spring (14), syringe needle is adjusted nut (15), syringe needle pin (16), needle guard spring (17), filter screen (18) is formed with the adjustable auto-controlled formula idling screw that screen cover (19) constitutes separable activity.During use, as long as with the working tension point of minimum stable idling pull of vacuum as needle spring (14) and valve spring (6), control syringe needle (13) and valve (5) is closed, at this moment, turn needle guard (12) can be adjusted idling, and according to the pull of vacuum of this idling phase, turn syringe needle pin (16) and valve pin (9) can be adjusted the elasticity of spring, to ensure the original performance characteristic under the various situations of Carburetor, make the acceleration of motor, power character unaffected.When forced idling, owing to be contained in further pressurized of the interior needle spring (14) of idling screw, syringe needle (13) is inhaled forward, connect atmosphere earlier, and then block idle jet, cut-out idling fuel feeding with working along both lines; Simultaneously, owing to be contained in the interior valve spring (6) of vacuum drums with auspicious further pressurized, valve (5) opened, with air inspiration cylinder, the little institute of air inlet basal area unvanquishable " crossing strong degree of vacuum " influence reaches the purpose of saving gasoline and machine oil when replenishing idling.When engine speed drops to modulatedly when deciding idling speed, under the tension force effect of needle spring of having set up (14) and valve spring (6), syringe needle (13), valve (5) are retracted original position (closing) and stop into air, at this moment, promptly recover normal idling.In addition, the utility model is at prominent low speed rather than the forced idling of changeing at a high speed, when inlet manifold " degree of vacuum " during greater than idling " degree of vacuum ", can also produce secondary-atomizing and air fuel-economizing effect, brought up a very fuel-economizing operating mode of maneuverability.
The utility model just is being based on above-mentioned structure feature, thereby makes it to have Simple and reasonable, adjust easy to use, adapt to all kinds of vehicles, cost is low The advantage such as honest and clean, safe and reliable, that fuel-economizing is remarkable. Application result shows that descending can Save gasoline 60-80%, in full forced idling situation, can save gasoline 100% General road also can be saved gasoline 7-10%, but machine oil saving also 30-60%, be a kind of desirable fuel-efficient device.
Claims (1)
- A kind of adjustable auto-controlled formula forced idling fuel-saving machine, by following of Carburetor, closure, the idling oil circuit, compositions such as idling screw, it is characterized in that between following of Carburetor and inlet manifold, having set up a fuel-saving machine seat (1), its be provided with on oblique through hole boss its front portion press fit in this oblique through hole by vacuum chamber (2), valve seat (3), whole packing (4), valve (5), valve spring (5), adjust nut (7), retaining nut (8), valve pin (9), the adjustable auto-controlled formula vacuum drums that filter screen (10) and screen cover (11) constitute, and original fixedly idling screw is improved to by oblique cover (12), syringe needle (13), needle spring (14), syringe needle debugging mode nut (15), syringe needle pin (16), needle guard spring (17), filter screen (18) and screen cover (19) constitute the adjustable auto-controlled formula idling screw of separable activity.
