Abstract

The utility model relates to an atomization adjusting device for the carburetor of an engine. The utility model comprises a valve body and a valve needle with a handle, wherein, the valve needle with a handle is arranged in the valve body; the valve body and the conical surface of the valve needle are sealed, the circumferential wall of a hollow cavity between the valve body and the conical surface of the valve needle are processed with oil inlet holes; the end part of the valve body is provided with a sealing gasket and an adjusting cap. The utility model which has the advantages of simple structure, simple installation, and convenient adjustment can simultaneously meet the conditions of thin atomization for gasoline and diesel oil and, can obviously limit the quantity of oil supply, and can provide good fine atomizing inflammable mixture for the engine.

Description

Atomising adjusting device for carburetor of engine

The utility model relates to the atomizing controlling device that oil mass is given in restriction that a kind of motor car engine Carburetor uses.

At present, the major economic indicators of Motor Vehicle depend on motor, and the wellatomized mixed gas that needs during engine combustion all will just can enter cylinder via Carburetor.For this reason, obtain oil-saving effect preferably, will improve design Carburetor.Existing single hole or diplopore Carburetor atomizing effect are all undesirable, and the inflammable mixture composition that enters cylinder can not be adjusted at any time and limit according to the applying working condition of motor.The Carburetor component all have one to have usefulness made to order in addition, and requirement on machining accuracy is higher, and are often different variant because of service condition according to the size of the definite main jet of concrete operating mode, influence the performance of motor sometimes.Adopt diesel engine gasoline replacing motor in particular for saving oil plant, existing Carburetor does not reach diesel oil mist condition, so combustion condition is poor, easily over-emitting black exhaust is badly in need of improving.

The purpose of this utility model provides a kind of engine and carburetor atomizing controlling device, it is simple in structure, installs, easy to adjust, can satisfy the mist condition of gasoline and diesel oil simultaneously, significant limitation is given oil mass, for motor provides good mist inflammable mixture.

The purpose of this utility model is achieved in that this device comprises valve body and assembles the needle of band handle in it, wherein valve body and needle conical surface seal, and cavity perisporium therebetween is processed with oil inlet hole, and valve end is assembled with sealing gasket and adjustment cap.On carbureter main jet, valve body perisporium filler opening is communicated with carburetor bowl the valve body oil outlet end spinning of this device, can be under the situation that does not change carburetor structure, improve its mist condition and the restriction cylinder is given oil mass.Because of substituting the carbureter main jet plug screw with the utility model, regulate the gap of itself and valve body by needle, the flow of control oil outlet, just can be under the situation that does not change the carburetor throat size, utilize main jet place pull of vacuum, by force from the conical surface of needle and the ejection of the annular space between valve body, so send forth more evenly, fuel oil energy atomizes preferably with fuel oil (diesel oil or gasoline).The mixed aerosol fuel oil that flows out from main jet is sprayed by the ring-type spout that the main jet pipe sprays into trunnion, and the high velocity air of the trunnion of being flowed through once more breaks up, thereby obtains further mistization, improves the mixed gas atomization condition, obviously improves engine performance.Because of not reducing the trunnion size, guarantee that trunnion forms enough big air-flow path, cylinder has enough aeration quantitys, not only can not reduce engine power for oil mass so reduce, and helps motor proper functioning under various operating modes on the contrary.This device has effectively overcome in the prior art, is the disadvantage that fuel-economizing is frequently adjusted by different operating modes carburetor structure, and the oil mass adjustment remedies in the use of existing Carburetor limit oil and needs cancellation or the auxilliary inconvenience that adds related device freely, significantly improves engine operation efficient.

The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 1 is a kind of concrete structure schematic representation of the present utility model.

Describe concrete structure of the present utility model in detail according to Fig. 1.This device is by valve body 1 and assemble that needle 3 in it forms.Needle 3 has handle 2, is used for adjusting the position of needle 3 in valve body 1.Valve body 1 and needle 3 conical surface seals are processed with filler opening at the cavity perisporium of valve body 1 and needle 3.Valve body 1 end is assembled with sealing gasket 5 and adjusts 4.During use, the valve body 1 oil outlet end of this device is tightened on the carbureter main jet, valve body 1 perisporium filler opening is communicated with carburetor bowl get final product.Regulate the handle 2 of needle 3, utilize the flow of the gap control oil outlet of its conical surface and valve body, just can realize the fuel quantity adjustment freely, and utilize main jet place pull of vacuum, fuel oil is evenly sprayed from the annular space of oil outlet, atomize.Under the situation that does not change the carburetor throat size, make the mixed gas of atomizing by trunnion the time, obtain further mistization.

The utility model is used for diesel engine and substitutes petrol engine, and the inflammable mixture of good atomization can directly be provided with existing Carburetor, simultaneously as fuel limiter, does not change carburetor structure, can limit to oil mass.

Claims (1)

1, a kind of engine and carburetor atomizing controlling device comprises valve body and assembles the needle of being with handle in it, and it is characterized in that valve body and needle conical surface seal, cavity perisporium therebetween is processed with oil inlet hole, and valve end is assembled with sealing gasket and adjusts cap.
