Abstract

The invention relates to a vibration reduction inlet pipe for a gasoline engine, which comprises a steel tube, a plastic sleeve and a steel plate, and is characterized in that the steel tube is embedded into one end of the plastic sleeve, and the steel plate is embedded into the other end of the plastic sleeve to ensure that the steel tube and the steel plate are flexibly connected into a whole through the plastic sleeve. By adopting the structure, the vibration reduction inlet pipe can significantly reduce the vibration of a carburetor and effectively avoid the condition of uneven concentration of gas mixture, thereby enhancing the stability of output power of the gasoline engine.

Description

Vibration reduction inlet pipe for gasoline engine
Technical field
The present invention relates to the technology of gasoline engine field, particularly two-stroke gasoline engine suction tude damping technology.
Background technique
Two-stroke gasoline engine because have that compact structure, volume are little, light weight, running speed-raising are fast etc., and distinguishing feature is widely used in many product scopes such as agricultural, forestry, gardening, family.
For the petrol engine that adopts float carburettor, its intake process is as follows, oil intake nozzle is connected by rubber pipe and fuel tank, open the oil-feed switch, gasoline passes through oil intake nozzle, the oil-feed switch, pintle valve seat enters float chamber, along with pasta in the float chamber increases, float also and then rises, when pasta rises to certain position, float drive float rocking arm and needle-valve block the aperture of pintle valve seat, stop oil-feed, after gasoline starting, running along with petrol engine, piston of gasoline engine moves up and down, and produces negative pressure at the trunnion place of Carburetor, and gasoline constantly passes through main jet under the negative pressure effect, the main jet pipe, and, enter the acting of cylinder body internal combustion from ejection of main jet spout part slit and air mixing formation mixed gas.Along with continuously outflowing of gasoline, the gasoline in the float chamber reduces, and pasta reduces, float, float rocking arm, needle-valve descend under the effect of self gravitation, thereby open needle-valve, gasoline constantly enters float chamber from fuel tank again, till pasta rises to aperture with pintle valve seat and blocks.The Carburetor that so goes round and begins again just continuously provides required gasoline to petrol engine, required inflammable mixture when satisfying the petrol engine proper functioning.When opening the throttle, main metering pin and plunger can move up under the effect of spring, make carburetor throat become big, and more air forms inflammable mixture by empty filter and gasoline, enters the cylinder body work by combustion.But, vibration can be passed to Carburetor by suction tude when in fact petrol engine is worked, the consequence that the Carburetor vibration is brought is: gasoline level shakiness in the float chamber, main metering pin and plunger are gone here and there up and down, cause the carburetor throat sectional area to change constantly, air and the formed mixture strength of gasoline also constantly change simultaneously.Because the mixture strength instability that enters cylinder body so petrol engine can not turn round and do work reposefully, causes the output power instability.Under the certain situation of throttle, rotating speed is still unstable.
Therefore effectively reduce the Carburetor vibration, avoid float chamber gasoline level shakiness as far as possible, prevent that main metering pin and plunger from going here and there up and down, solve because mixture strength is unstable and cause petrol engine rotational speed and jiggly problem of doing work, become that those skilled in the art attempt to capture but the technical barrier of not capturing as yet always.
Summary of the invention
The object of the invention provides a kind of vibration reduction inlet pipe for gasoline engine, especially at the petrol engine that adopts float carburettor, by improvement to air feeder structure, can obviously reduce the vibration of Carburetor, avoid the uneven situation of mixture strength effectively, thereby improve the stability of petrol engine output power.
The technological scheme that the present invention takes is, a kind of vibration reduction inlet pipe for gasoline engine comprises steel pipe, plastic sheath, steel plate, it is characterized in that: steel pipe is embedded in an end of plastic sheath, the other end of plastic sheath is inlaid with steel plate, makes steel pipe and steel plate flexibly connect by plastic sheath and is one.
The outer wall of inlaying end at steel pipe is provided with serrate slot.
Steel plate is provided with vent, and the cylinder body intake port shape of vent shape and petrol engine is complementary.
The said steel pipe of the present invention is provided with serrate slot at the connecting end outer wall of steel pipe and plastic sheath, and this serrate slot can prevent effectively that steel pipe and plastic sheath from coming off.Steel plate is provided with vent and screw hole, and the cylinder body intake port shape of vent shape and petrol engine is complementary, and screw hole is used for fixing suction tude on cylinder body.Steel pipe and steel plate flexibly connect by plastic sheath and are one, and the vibration of the petrol engine of decaying effectively improves the influence that Carburetor is produced because of the petrol engine vibration significantly.Said plastic sheath can be that the raw material that rubber etc. has a favorable elasticity is made, and its shape can be designed to variform as required.
The invention has the beneficial effects as follows, compare with traditional suction tude, because suction tude of the present invention has adopted plastic sheath, make the vibration of petrol engine in transmittance process, decay very obvious, thereby the effectiveness in vibration suppression to Carburetor is very obvious, avoid mixture strength inhomogeneous effectively, improved the stability of petrol engine output power.
When reducing the Carburetor vibration, also improved the atomizing effect of fuel combination, make the fuel consumption rate of petrol engine that tangible reduction also be arranged.

Sequence number explanation in the accompanying drawing: 1. cylinder body, 2. vibration reduction inlet pipe, 2a. steel pipe, 2b. plastic sheath, 2c. steel plate, 3. screw, 4. bolt, 5. Carburetor, 6. serrate slot, 7. vent, 8. screw hole, 9. cylinder body suction port, 10. empty filter
Embodiment
As Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, according to petrol engine of the present invention, cylinder body 1 links to each other with vibration reduction inlet pipe 2 by screw 3, and vibration reduction inlet pipe 2 links to each other with Carburetor 5 by bolt 4, and Carburetor 5 links to each other with empty filter 10.
Vibration reduction inlet pipe 2 comprises steel pipe 2a, plastic sheath 2b, steel plate 2c, steel pipe 2a is embedded in the end of plastic sheath 2b, the other end of plastic sheath 2b is inlaid with steel plate 2c, make steel pipe 2a and steel plate 2c flexibly connect and be one by plastic sheath 2b, the outer wall that steel pipe 2a inlays end is provided with serrate slot 6, steel plate 2c is provided with vent 7 and screw hole 8, and cylinder body 1 is provided with cylinder body suction port 9.
Because plastic sheath 2b makes by the raw material with favorable elasticity, can decay the effectively vibration of petrol engine of vibration reduction inlet pipe 2 improves the influence of petrol engine vibration to Carburetor 5 significantly.After Carburetor 5 vibrations reduce, avoid mixture strength inhomogeneous effectively, improved the stability of petrol engine output power.
