Abstract
The utility model discloses a fuel injection needle. The needle comprises a round rod-shaped body and the upper end of the rod-shaped body is provided with a regulating ring groove used for arrangement of a flexible card. The needle is characterized in that the lower part of the round rod-shaped body is provided with a cavity getting through the lower part and the periphery wall of the cavity is provided with a radial oil spraying Millipore. When in working, the needle can effectively guarantee that fuel can be sprayed out from the radial oil spraying Millipore and then can be atomized.
Description
Technical field: the utility model relates to a kind of Carburetor.
Technical background: 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.
Summary of the invention: the purpose of this utility model is the spindle that a kind of Carburetor will be provided, and during work, it can effectively ensure fuel oil from its radially oil spout micropore ejection, thereby in order to atomizing.
The utility model is to constitute like this, it comprises the circular rod-shaped body, the upper end of rhabodoid has in order to the adjusting annular groove of elastic card to be installed, and it is characterized in that: have the cavity that is through to the lower end in the lower body of circular rod-shaped body, offer radially oil spout micropore on the cavity periphery wall.
The spindle of Carburetor of the present utility model the time is inserted in the oil nozzle equally in work, when under the effect of fuel oil in negative pressure during the flow bean ejection, flows 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 original spindle, it is good to the utlity model has atomizing effect, helps full combustion of fuel and fuel-saving remarkable advantage.
Description of drawings: Fig. 1 is the utility model embodiment organigram.
Fig. 2 is the A-A sectional view of Fig. 1.
Fig. 3 is the oil spout micropore distribution schematic representation of spindle.
Fig. 4 is the utility model embodiment working state view.
In Fig. 4,1 expression circular rod-shaped spindle, 5 expression Carburetors, the oil nozzle of trunnion one side is located in 6 expressions, the pilot spool of 7 expression motion valve assemblages.
Embodiment: with reference to Fig. 1 Fig. 2 and Fig. 3, the utility model embodiment comprises circular rod-shaped body 1, the upper end of rhabodoid has in order to the adjusting annular groove 2 of elastic card to be installed, it is characterized in that: have the cavity 3 that is through to the lower end in the lower body of circular rod-shaped body, offer radially oil spout micropore 4 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.
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.
