Abstract
The utility model relates to a vehicle carburetor, including a main jet of economizing carburetor of motorcycles and small gasoline engines. The upper end of the main jet is provided with a nozzle sealed on the end, and the wall of the nozzle is provided with a plurality of lateral jet holes. In the utility model, the straight jet of oil supply is changed into the lateral jet and the lateral holes spray the oil step by step with the accelerated rotate speed. As the oil particle is small and is pre-mixed into bubbles, the air mixture is even with good atomization when entering a hollow throat. In negative load changes, the respond is quick and the fuel reverse-jet is reduced. In practical use, the low-speed driving at high shift is more comfortable and stable. The utility model has the advantages of sensitive throttle, no power weakening, more 25% oil saving than stipulated in the motorcycle manual, lean fuel combustion, exhaust environmental protection and easy start-up, particularly suitable for cold winter with fewer throttles.
Description
Technical field:
The utility model relates to the Motor Vehicle Carburetor.
Background technique:
Motorcycle, miniature gasoline engine Carburetor fuel feeding owner will be by idle metering jet, main jet fuel feeding, and oil oil directly sprays through mist pipe by main jet and enters cylinder in the trunnion air mixing, because of the big atomizing effect of oil particles not good enough, oil inflame is not thorough, the oil consumption height, tail gas exceeds standard, and influences environment.The use reaction velocity is slow, and it is serious that fuel oil is regurgitated phenomenon, and operation is unstable, the idling height.
Summary of the invention:
The purpose of this utility model is to overcome above-mentioned not enough problem, and a kind of motorcycle, miniature gasoline engine fuel-economizing carbureter main jet are provided, and is rational in infrastructure, simple, fuel-economizing, environmental protection.
The technological scheme that the utility model is adopted for achieving the above object is: motorcycle, miniature gasoline engine fuel-economizing carbureter main jet, and jet pipe fixedly is equipped with in the main jet upper end, and the sealing of jet pipe termination has a plurality of side spray orifices on the jet pipe wall.
The thin hypomere of described jet pipe epimere is thick, and the jet pipe butt end is fixedlyed connected with the main jet upper end, and the thick section of jet pipe internal diameter is greater than 3 times of main jet internal diameters, and the thin segment internal diameter is greater than the main jet internal diameter.
Described jet pipe upside spray orifice is 3-5 row, and every row's side spray orifice is 2-4.
Described side injection diameter is 0.20-0.30mm.
The thick section of described jet pipe upside injection diameter is greater than thin segment upside injection diameter.
The utility model fuel feeding changes side spray into by straight spray, and along with rotating speed improves, the oil spout step by step of side spray orifice because the particle of oil is tiny, and sneaks into bubble in advance, mixes entering the trunnion air stream, and atomizing is better.When load variations, be swift in response, fuel oil is regurgitated phenomenon and alleviated, and is in actual use, happier steady during the high gear low speed driving, throttle is quick on the draw, and power do not subtract, and is more fuel-efficient more than 25% than specified standard in the motorcycle specification, the fuel oil lean combustion, the tail gas environmental protection, wherein CO content below 0.3, HC content is below 0.45, starting easily, particularly winter low temperature can be with air door less.
Description of drawings:
Fig. 1 is the utility model structural representation.
Embodiment:
Motorcycle as shown in Figure 1, miniature gasoline engine fuel-economizing carbureter main jet, have connecting thread on the main jet, jet pipe (3) fixedly is equipped with in main jet upper end (1), and the thin hypomere of jet pipe epimere is thick, and the jet pipe butt end is fixedlyed connected with the main jet upper end, the thick section of jet pipe internal diameter is greater than 3 times of main jet internal diameters, the thin segment internal diameter is greater than the main jet internal diameter, and jet pipe thin segment termination (4) sealing has five row's side spray orifices (2) on the jet pipe wall, wherein thick section upside spray orifice aperture 0.30mm, thin segment upside spray orifice aperture 0.25mm.
In the practical application, according to different automobile types jet pipe length difference, side spray orifice row number, each row's upside nozzle hole number is all inequality.
Claims (5)
1. motorcycle, miniature gasoline engine fuel-economizing carbureter main jet is characterized in that: jet pipe (3) fixedly is equipped with in main jet upper end (1), and jet pipe termination (4) are sealed, and have a plurality of side spray orifices (2) on the jet pipe wall.
2. motorcycle according to claim 1, miniature gasoline engine fuel-economizing carbureter main jet, it is characterized in that: the thin hypomere of jet pipe (3) epimere is thick, the jet pipe butt end is fixedlyed connected with main jet upper end (1), and the thick section of jet pipe internal diameter is greater than 3 times of main jet internal diameters, and the thin segment internal diameter is greater than the main jet internal diameter.
3. motorcycle according to claim 1, miniature gasoline engine fuel-economizing carbureter main jet is characterized in that: jet pipe (3) upside spray orifice (2) is 2-4 for 3-5 row, every row's side spray orifice.
