Abstract
The utility model discloses an idling system for a carburetor. The idling system comprises a carburetor body, an air throttle arranged in the carburetor body, an idling oil mass hole which is communicated with the air throttle and two idling air inlet channels which are communicated with the idling oil mass hole, wherein the two idling air intake channels comprise an idling air inlet channel and an idling compensation air inlet channel; one end of the idling air inlet channel is communicated with the idling oil mass hole, and the other end of the idling air inlet channel is fixed by an idling air inflow hole; an idling adjusting screw is arranged in the idling compensation air inlet channel; a transitional hole is formed in the carburetor body; and one end of the transitional hole is communicated with the air throttle and the idling oil mass hole, and the other end of the transitional hole is provided with a steel ball. According to the idling system, idling inflow can be adjusted accurately by arranging the two idling air intake channels, so that the idling system is stable and high in consistency.
Description
Technical field
The utility model relates to motorcycle mechanical fitting field, relates in particular to a kind of idling system of motorcycle carburetor.
Background technique
Carburetor is a kind of gasoline and air mixing with some, so that the device of normal working of engine.Carburetor on automobile, the motorcycle is the vitals that forms inflammable mixture, and fuel oil and air after filtering mix at Carburetor, forms vaporific burning mixture and gets into the firing chamber internal combustion through the valve of motor.
Be equipped with idling system on the existing motorcycle carburetor, the function of this idling system is to guarantee that motor supplies with required rich mixture when idling or low speed, and cooperates with main oil supply system, supplies by the inflammable mixture of the little load of low speed when the moderate duty transition.Present motorcycle carburetor on the market is the Carburetor (shown in Figure 1) of PZ19 series especially; Only comprise one tunnel idling air inlet passage 2 in its Carburetor body 1, so the adjustment of idle mixture richness adopts all the size of direct adjusting idling air inlet amount to realize.When adopting this method to adjust, the big minor swing of idling air inlet amount is bigger, and the idling air inlet amount and idle adjusting screw 3 number of turns are linear poor during adjusting, thereby cause the conformity such as the number of turns of idling system relatively poor.Simultaneously, carrying out Finished Motorcycle of motorcycle when coupling discharging with above-mentioned this type of Carburetor,, making that therefore the stability of car load discharging is also relatively poor because the fluctuation of idling air inlet amount is big when regulating.
The model utility content
The purpose of the utility model is, a kind of Carburetor idling system is provided, and it is provided with two-way idling air inlet passage, can adjust more accurately the idling air inflow, makes that idling system is more stable, conformity is better.
For realizing above-mentioned purpose; The utility model provides a kind of Carburetor idling system; Comprise: the Carburetor body, be located at the intrinsic air throttle of Carburetor, and the idling jet that is connected with air throttle; It also comprises the two-way idling air inlet passage that is connected with idling jet, and this two-way idling air inlet passage comprises an idling gas-entered passageway, reaches idling compensation gas-entered passageway; This idling gas-entered passageway one end is connected with idling jet, and the other end is fixed through an idling air inlet metering-orifice; Be provided with an idle adjusting screw in this idling compensation gas-entered passageway; Be provided with a transitional pore in the said Carburetor body, this transitional pore one end is connected with air throttle and idling jet respectively, and the other end is provided with a steel ball.
The Carburetor idling system of the utility model; It is through being provided with two-way idling air inlet passage; Thereby realize adjustment to whole idling system air inflow; Not only more accurate to the adjustment of idling air inlet amount, and the linearity of idling air inlet amount and the idle adjusting screw number of turns when having promoted idle, regulate more stable; Simultaneously, when carrying out Finished Motorcycle of motorcycle emissions adjustment coupling, have better stability and conformity.
Description of drawings
Fig. 1 is the Carburetor idling system structural representation of PZ19 series in the existing technology;
Fig. 2 the utility model Carburetor idle system is unified the structural representation of specific embodiment.
Embodiment
As shown in Figure 2, the utility model provides a kind of Carburetor idling system, and it comprises Carburetor body 10, be located at air throttle 20 in the Carburetor body 10, and the idling jet 30 that is connected with air throttle 20.Especially, the utility model also comprises the two-way idling air inlet passage that is connected with idling jet 30, and this two-way idling air inlet passage comprises an idling gas-entered passageway 40, and idling compensation gas-entered passageway 50.These idling gas-entered passageway 40 1 ends are connected with idling jet 30, and the other end is fixing through an idling air inlet metering-orifice 42.Be provided with an adjustable idle adjusting screw 52 in this idling compensation gas-entered passageway 50.Wherein, also be provided with a transitional pore 12 in the said Carburetor body 10, this transitional pore 12 is a fixing idling oil outlet, and the one of which end is connected with air throttle 20 and idling jet 30 respectively, and the other end is provided with a steel ball 14.
Idling foaming pipe 32 is installed in the idling jet 30, and these idling foaming pipe 32 1 ends stretch into and are arranged in the idling jet 30, and the other end stretches into and impregnated in pasta 34 times.During idling, gasoline gets into through idling jet 30, through with the air mixing that gets into by two-way idling air inlet passage after, produce the foamed mixed gas, get into engine combustions by transitional pore 12 ejections at last.
As a kind of specific embodiment of the utility model, said idling gas-entered passageway 40 parallel idling compensation gas-entered passageway 50 tops that are arranged at.This idling gas-entered passageway 40, and idling compensation gas-entered passageway 50 1 ends all be connected with idling jet 30 through a suction tude 45, said idle adjusting screw 52 is located at idling and is compensated the position that gas-entered passageway 50 is connected with suction tude 45.Wherein, This idling gas-entered passageway 40 is as the basic air feed of idling; And idling compensation gas-entered passageway 50 carries out the air inflow adjusting through idle adjusting screw 52, through the common cooperation of this two-way idling air inlet passage, thereby realizes the adjustment to whole idling system air inflow.
The above; For the person of ordinary skill of the art; Can make other various corresponding changes and distortion according to the technological scheme and the technical conceive of the utility model, and all these changes and distortion all should belong to the protection domain of the utility model accompanying Claim.
