Abstract

The invention aims to provide a combined-type rotary oil spray nozzle which comprises a needle valve body and a nozzle body, and further comprises an oil spray nozzle housing, wherein the needle valve body is mounted in the nozzle body; a spray orifice is formed in the nozzle body; the oil spray nozzle housing is mounted at the exterior at the lower part of the nozzle body; an annular groove is formed in the nozzle body; the upper end of the oil spray nozzle housing is embedded in the groove; a thread is formed in the oil spray nozzle housing; the oil spray nozzle housing can rotate around the nozzle body under the action of the thread; an oil spray nozzle housing spray orifice corresponding to the spray orifice in the nozzle body is formed in the oil spray nozzle housing. The combined-type rotary oil spray nozzle has the advantages that the moving range of spray can be broadened; the contact area between the spray and air is enlarged; sprayed oil can flow with a certain speed, so as to ensure better mixing between oil and air, and improve oil-air mixture.

Description

A kind of combined type rotation spray oil nozzle
Technical field
What the present invention relates to is a kind of motor, specifically the oil nozzle of motor.
Background technique
In needing the internal-combustion engine of oil spout, the injection of fuel oil, atomizing and evaporation and have critical effect with the combustion and emission that mixes motor of air.Motor forms inflammable mixture, for burning after process air-fuel mixture process.Inflammable mixture refers to a kind of mixed gas of being comprised of gaseous fuel and air, and it forms and state should guarantee that its depression burns in cylinder, its content mainly comprise fuel injection, fragmentation, atomize and be distributed to process in the space of firing chamber; Fuel particles evaporation, diffusion mix with the air of indoor sport, form inflammable mixture.
The fuel oil that motor is difficult to realize spraying in cylinder evenly mixes with the complete of air, and the inhomogeneous meeting of air-fuel mixture causes burning insufficient.In the rare place of mixed gas, air can not get sufficient utilization; In the denseer place of mixed gas, fuel is slow because anoxic causes burning, and even because incomplete combustion causes black smoke from exhaust, contains a large amount of harmful matters in the gas of discharge air is polluted.
At present, for improving the mixing of fuel oil and air, taked multiple advanced technology.For example:
(1) structural type of firing chamber is improved in firing chamber, and it is mated with oil-fired system and gas handling system better;
(2) gas handling system adopts variable air inlet eddy current four air valve structures, improves the mixing rate of fuel and air;
(3) injection system, nozzle adopts double-deck jet orifice structure, and atomization quality improves, and the evaporation of fuel oil is strengthened, and internal combustion oil of cylinder distributes more even.
Summary of the invention
The object of the present invention is to provide the mixed uniformly a kind of combined type rotation spray oil nozzle that to realize oil gas.
The object of the present invention is achieved like this:
A kind of combined type rotation spray of the present invention oil nozzle, comprise needle-valve body, nozzle body, needle-valve body is arranged in nozzle body, have spray orifice on nozzle body, it is characterized in that: also comprise the oil nozzle shell, the oil nozzle shell is arranged on the outside of nozzle body lower end, the groove of annular is set on nozzle body, the upper end of oil nozzle shell is embedded in groove, be provided with screw thread on the oil nozzle shell, the oil nozzle shell can rotate around nozzle body under the effect of screw thread, also is provided with the oil nozzle shell spray orifice corresponding with the spray orifice on nozzle body on the oil nozzle shell.
Advantage of the present invention is: the present invention has not only enlarged the range of movement of spraying, has increased the area of contact of spraying and gas; And make oil spout have certain flowing velocity, and impel oil better to mix with air, reach the purpose of improving air-fuel mixture.
Description of drawings
Fig. 1 is structural representation of the present invention;
Fig. 2 is injection of the present invention figure as a result.
Embodiment
For example the present invention is described in more detail below in conjunction with accompanying drawing:
In conjunction with Fig. 1~2, the present invention includes needle-valve body 1, nozzle body 2, needle-valve body 1 is arranged on 2 li of nozzle bodies, have spray orifice 3 on nozzle body 2, oil nozzle shell 4 is arranged on the outside of nozzle body 2 lower ends, and the groove of annular is set on nozzle body 2, the upper end of oil nozzle shell 4 is embedded in groove, be provided with screw thread 5 on oil nozzle shell 4, oil nozzle shell 4 can around nozzle body 2 rotations under the effect of screw thread 5, also be provided with the oil nozzle shell spray orifice 6 corresponding with the spray orifice 3 on nozzle body on oil nozzle shell 4.
diesel engine is when work, the crank-driven camshaft rotates, fuel from fuel tank is through filter cleaner, oil transfer pump is sent into the low pressure oil pocket of Injection Pump with certain pressure, plunger cavity communicates with the low pressure oil pocket, fuel oil is through advancing, spill port enters plunger cavity, when the plunger end face rises to and advances, when the spill port top edge is concordant, plunger cavity and low-pressure reservoir isolation, the fuel oil that plunger continues to move upward in plunger cavity is compressed, pressure raises, the fuel oil that is sealed in plunger cavity backs down needle-valve and enters oil nozzle along with the increase of pressure, at first 3 ejections of the spray orifice from the nozzle body 2, because the fuel oil that sprays has higher jet pressure, between nozzle body 2 and oil nozzle shell 4 in limited space, high pressure orders about oil nozzle shell 4 High Rotation Speed under the leading role of screw thread 5, spray orifice 6 in rotation on the oil nozzle shell sprays at a high speed the firing chamber to fuel oil, in the moment of fuel oil ejection, except the diffusion of self, also produce circumferential motion, enlarged the range of movement of spraying, increased the area of contact of spraying and gas, impel oil better to mix with air, improve air-fuel mixture.
Two length dimensions in Fig. 1 shown in alphabetical L, H can carry out suitable adjustment according to actual conditions.
