Abstract
The utility model relates to a motorcycle carburetor, in particular to a motorcycle carburetor of a double-layer idle metering jet, wherein the double-layer idle metering jet is connected with the carburetor, and the double-layer idle metering jet is a compensating jet and is riveted on the idle metering jet through interference fit. The motorcycle carburetor substantially solves the problem that because the rotating speed is low, the flow speed of air and gasoline is slow when a prior engine operates in an idle speed and low speed, and the evaporation and atomization conditions of the gasoline are not well. The motorcycle carburetor can lead fuel oil and the air to fully mixed, thereby greatly increasing the atomization effect, leading the engine to be more easily and fully burnt when the engine operates in the idle speed and low speed, and achieving the purpose of saving gasoline and reducing emission.
Description
Technical field
The utility model relates to motorcycle carburetor, particularly a kind of double-deck idle metering jet motorcycle carburetor.
Background technique
Motor is when idling and low-speed running, because rotating speed is lower, air and gasoline flow velocity are slower, the evaporation and the atomization condition of gasoline are bad, at this moment gasoline major part is bigger particle, the mixed gas atomization badness of formation, and it is bad to cause motor to burn when idling and low speed, cause oil consumption higher, discharging exceeds standard.
The model utility content
The purpose of this utility model is to provide a kind of double-deck idle metering jet motorcycle carburetor, mainly solve available engine when idling and low-speed running, because rotating speed is lower, air and gasoline flow velocity are slower, the problem that the evaporation of gasoline and atomization condition are bad, it can make fuel oil fully mix with air, and atomizing effect improves greatly, it is easier, more abundant that motor is burnt when idling and low speed, thereby reach the purpose of fuel-economizing and reduction of discharging.
For realizing above-mentioned model utility purpose, the technical solution of the utility model is:
A kind of double-deck idle metering jet motorcycle carburetor, it is characterized in that: double-deck idle metering jet is connected on the Carburetor, and this bilayer idle metering jet is that a compensating jet passes through the interference fit riveted on idle metering jet.
Described double-deck idle metering jet motorcycle carburetor is characterized in that: described double-deck idle metering jet by screw-threaded coupling on Carburetor.
Described double-deck idle metering jet motorcycle carburetor is characterized in that: the aperture ratio of the aperture of described compensating jet and idle metering jet is 1: 1.06.
By said structure, the utility model has the advantages that:
The utility model Carburetor has double-deck idle metering jet structure, the throttling action of its compensating jet, precondition in identical motor negative suction, the flowing velocity of fuel oil in double-deck idle metering jet accelerated, fuel particles speeds up with the air mixing that enters in the idling oil well, and fuel oil is fully mixed with air, and atomizing effect improves greatly, it is easier, more abundant that motor is burnt when idling and low speed, thereby reach the purpose of fuel-economizing and reduction of discharging.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structural representation of double-deck idle metering jet in the utility model.
Among the figure:
The 1-throttle valve; The 2-low speed jet;
The 3-lower cover; The 4-idle metering jet;
The 5-fuel oil; The 6-compensating jet;
The 7-air inlet.
Embodiment
See also Fig. 1,2, the utility model provides a kind of double-deck idle metering jet motorcycle carburetor.It mainly is in order to solve the atomizing problem of low speed fuel oil.As shown in the figure: a compensating jet 6 on common idle metering jet 4, is formed double-deck idle metering jet by the interference fit riveted.Double-deck idle metering jet by screw-threaded coupling on Carburetor.
Motor is when idling and low-speed running, throttle valve 1 aperture is less on the Carburetor, the engine piston negative pressure that produces that moves up and down can not act on the main jet oil pipe, can only act on low speed jet 2 places of Carburetor, powerful negative pressure with mixed gas from low speed jet 2 sucking-offs and enter motor.Because the throttling action of the compensating jet 6 on the double-deck idle metering jet, precondition in identical motor negative suction, the flowing velocity of fuel oil 5 in double-deck idle metering jet accelerated, fuel particles speeds up with the air mixing that enters in the idling oil well, fuel oil is fully mixed with air, atomizing effect improves greatly, and it is easier, more abundant that motor is burnt when idling and low speed, thereby reaches the purpose of fuel-economizing and reduction of discharging.
On the other hand, because the more little motor of discharge capacity, its idle metering jet aperture is more little, and too small metering-orifice has brought very big difficulty to processing.Adopt after the double-deck idle metering jet because the throttling action of compensating jet, just can suitably strengthen the idle metering jet aperture, by experiment, the aperture ratio of the aperture of compensating jet and idle metering jet be 1: 1.06 o'clock be best of breed, and can not change the original flow value of idle metering jet, bring convenience also for the processing of idle metering jet, can guarantee the conformity of part better.
The above only is the actual example of the utility model in we produce, and is not to be used for limiting practical range of the present utility model.The i.e. all equivalences of doing according to the content of the utility model claim of this model utility change and modify, and all should be technology category of the present utility model.
