Abstract
The utility model relates to an oil injection main body structure for a carburetor. The utility model comprises a carburetor main body, an oil injection nozzle arranged on one side of a hollow throat, and a throttle valve component arranged on the other side of the hollow throat, wherein, an oil needle is arranged on the bearing hole of the guide plunger piston end part of the throttle valve component, and the lower end of the oil needle is inserted in the oil injection nozzle. The utility model is characterized in that the oil needle is a circular rod-shaped body, a cavity extending to the lower end is arranged in the circular rod-shaped body, and a radial oil injection microbore is arranged on the cirumferential wall of the cavity. The mechanism can effectively ensure the atomization when the fuel is in the operation.
Description
The utility model relates to a kind of oil spout main body mechanism of Carburetor.
The carburetor needle valve of existing automobile or motorcycle is tapered, and during work, the spindle that is inserted in the oil nozzle moves up and down under the drive of plunger, thereby controls the oil mass of ejection by the gap that changes spindle cross section and oil nozzle.The major defect that exists is: when petrol engine quickened, the cross section and the gap between the oil nozzle of spindle were bigger, so the fuel oil that overflows is generally the granular oil droplet, and therefore influence atomizing.
The purpose of this utility model is the oil spout main body mechanism that a kind of Carburetor will be provided, and this mechanism can effectively ensure the atomizing of fuel oil at work.
The utility model is to constitute like this, it comprises the Carburetor body, be located at the oil nozzle and the motion valve assemblage of being located at the trunnion opposite side of trunnion one side, the bearing hole of the pilot spool end of motion valve assemblage is provided with spindle, the lower end of this spindle is inserted in the oil nozzle, it is characterized in that: the rounded rhabodoid of spindle, have the cavity that is through to the lower end in its body, offer radially oil spout micropore on the cavity periphery wall.
When flow bean when ejection under the effect of fuel oil in negative pressure, flow to earlier in the cavity in the carburetor needle valve lower body, and then from the radial pore oil spout outward of spindle.Therefore, the utility model can effectively ensure in the moment of oil spout and make fuel-oil atmozation and mix with even air.When needs refueled, the user was as long as twitch spindle, make be exposed to the trunnion place have radially that the spindle of oil spout micropore partly increases, can strengthen fuel injection quantity.Otherwise, allow spindle insert oil nozzle, reduce the radially spindle part of oil spout micropore that has that is exposed to the trunnion place, fuel injection quantity promptly reduces, therefore, and than existing Carburetor, it is good to the utlity model has fuel atomization effect, helps full combustion of fuel and fuel-saving remarkable advantage.
Below in conjunction with drawings and Examples the utility model is specifically described.
Fig. 1 is the utility model embodiment organigram.
Fig. 2 is the spindle organigram.
Fig. 3 is the A-A sectional view of Fig. 2.
Fig. 4 is the oil spout micropore distribution schematic representation of spindle.
Fig. 5 is the pilot spool worm's eye view.
With reference to accompanying drawing, the utility model embodiment comprises Carburetor body 1, be located at the oil nozzle 2 and the motion valve assemblage of being located at the trunnion opposite side of trunnion one side, the bearing hole of pilot spool 3 ends of motion valve assemblage is provided with spindle 4, the lower end of this spindle is inserted in the oil nozzle, it is characterized in that: the rounded rhabodoid of spindle, have the cavity 5 that is through to the lower end in its body, offer radially oil spout micropore 6 on the cavity periphery wall.
Enter cylinder and fully burning in order to help combustion gas, above-mentioned radially oil spout micropore can be distributed in the circular rod-shaped body on a side perisporium of air inlet downstream direction.Best design is to be laid with radially oil spout micropore along its length in 120 ° of scopes of circular rod-shaped body bottom perisporium.The aperture of described radially oil spout micropore is 0.1-1mm.
In order to ensure the oil spout working surface of spindle towards the air inlet downstream direction, offer protruding button guiding groove 7 on the supporting hole wall of above-mentioned pilot spool front end, spindle top one side correspondence is provided with the protruding button 8 of the guiding that is embedded in the protruding button guiding groove, and this protruding button that leads is positioned at adjusting annular groove 9 belows of spindle.
The utility model is novel, and is reasonable in design, but the experiment proved that and adopt internal-combustion engine of the present utility model fuel-economizing 25-30% under with the situation of constant power.Applying not only of it can be saved fuel oil, improves the operating mode of Carburetor and internal-combustion engine, and will purify the smoke evacuation of locomotive, improves urban air.
