Description
Technical field
The present invention relates to a kind of engine atomizer assembly for two stroke engine.
Background technology
At present, engine atomizer assembly includes air inlet pipe, atomising mechanism, air intake branch, check valve and base, air inlet pipe with
The entrance point connection of atomising mechanism, air intake branch one end connects with the outlet section of atomising mechanism, and the air intake branch other end and base
Connecting, and be provided with check valve in base, the effect of atomising mechanism is to mix with the air inlet in air inlet pipe after oil spraying, leads to subsequently
Cross air intake branch and check valve is delivered in the combustion chamber of engine.But the engine atomizer assembly of prior art makes on unmanned plane
Used time, the rotating speed of engine is relatively low so that the ceiling of unmanned plane can only achieve 5000m, it is impossible to meet actual use need
Ask.
Summary of the invention
The present invention is directed to problem above provides one can improve engine speed so that unmanned plane ceiling reaches starting of 1～2 myriametres
Machine atomizer assembly.
The present invention solves the technical scheme used by problem above: provide a kind of engine atomizer assembly with following structure,
It includes that atomising mechanism and check valve, described atomising mechanism are provided with air inlet, outlet, oil inlet passage and air door regulation axle,
Air door, described air door regulation axle it is provided with in communicating passage between described air inlet and outlet, and air inlet and outlet
One end is connected with air door, and the air door regulation axle other end is positioned at outside atomising mechanism, and described atomising mechanism is provided with the second oil inlet pipe
With the second atomizer, in the second described atomizer communicating passage between air inlet and outlet, and the second atomizer is at wind
Door is away from the side of air inlet, and second described oil inlet pipe one end connects with oil inlet passage, the second oil inlet pipe other end and the second spray
Oil nozzle connects, and the second described oil inlet pipe is provided with Yan Kaifamen.
After using above structure, compared with prior art, due to the fact that and be provided with the second in-line and the second atomizer, then
When unmanned plane uses, when unmanned plane arrives 5000m, need to increase engine speed further to improve unmanned plane
Ceiling, but originally the most no matter air door is opened many rotating speeds that mostly cannot improve engine further (those skilled in the art is thought raising
Engine speed, it is only necessary to increase intake, increase the distributive value of original atomizer simultaneously, but equal nothing in practical operation
Method improves the ceiling of unmanned plane further), and under the effect of the second in-line and the second atomizer, along with the continuation of air door increases
Greatly, while air inflow continues to increase, increased the spray amount of fuel oil further by the second injection tubing, improve further and send out
The power of motivation, and then arrive raising engine speed, engine speed can improve at least 10%, and promote unmanned plane ceiling
Purpose, can make the ceiling of unmanned plane reach 1～2 myriametres；And it is additionally provided with Yan Kaifamen, Yan Kaifamen when air door opens 50%
Opening, this allows for unmanned plane when 5000m and following height, and the second injection tubing is closed, and then can prevent nothing
The man-machine oil consumption increase when original height, does not the most affect unmanned plane simultaneously and continues to improve ceiling, make the use of unmanned plane more yet
Flexibly, fuel efficiency is higher.Therefore the present invention has and can improve engine speed so that unmanned plane ceiling reaches 1～2 myriametres
Feature.
As improvement, the regulation axle of described Yan Kaifamen is integral type structure with air door regulation axle, after the most this structure is arranged,
Make need not additionally to increase controlling organization can Yan Kaifamen be controlled, overall weight and the volume of the present invention can be controlled, with
Just the present invention is more suitable on unmanned plane using, and does not increase the volume of unmanned plane.
As improving further, described check valve includes that valve seat, valve block and banking stop, described valve seat are provided with several and go out
Gas port, all corresponding valve block in described each gas outlet, described valve block one end is fixed on valve seat, and the valve block other end covers
At gas outlet, the corresponding banking stop of described each valve block, described banking stop one end is fixed on valve seat, and banking stop is another
One end is positioned at the top of valve block, and the radian that the banking stop other end upwarps is 0.07～0.54 radian, the check valve of the most this structure,
Structure is relatively simple, and preparation cost is relatively low, and valve block is the most appropriate in the little angle opened of effect of banking stop, prevents valve block from opening
Relatively big and and the situation generation that cause valve block damages relatively big with the impact of valve seat when replying so that the service life of valve block is longer.
As further improving, on described valve seat, the position of each gas outlet is equipped with annular groove, and annular groove edge
The edge gas outlet extends, and is equipped with the rubber blanket of annular in described each annular groove, then under the buffering of rubber blanket,
Can extend the service life of valve block further, valve block extends more than 30% than original service life.
As preferably, described radian is 0.34～0.54 radian, and when this arc range, the rotating speed of engine is higher than other arc
Degree so that high-revolving state at engine, has again preferable fuel economy simultaneously.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described further.
A kind of engine atomizer assembly as depicted in figs. 1 and 2, it includes that atomising mechanism 1 and check valve 2 (the most also wrap
Include other parts, but owing to being not directed to the inventive point of the invention, therefore do not repeat them here), on described atomising mechanism 1
Being provided with air inlet 11, outlet 12, oil inlet passage 13 and air door regulation axle 14, described air inlet 11 connects with outlet 12,
And in the communicating passage between air inlet 11 and outlet 12, it is provided with air door, described air door regulation axle 14 one end is connected with air door,
Air door regulation axle 14 other end is positioned at outside atomising mechanism 1, and usual air door is arranged on the side of nearly outlet 12, described atomization
Mechanism 1 is provided with the second oil inlet pipe 15 and the second atomizer, the outside of the atomising mechanism 1 that the second oil inlet pipe 15 is arranged, described
The second atomizer air inlet 11 and outlet 12 between communicating passage in, and the second atomizer at air door away from air inlet
The side of 11, usual second atomizer is arranged on the opposite of former atomizer, naturally it is also possible to be arranged on the both sides of former atomizer, institute
Second oil inlet pipe 15 one end stated connects with oil inlet passage 13, second oil inlet pipe 15 other end and the connection of the second atomizer, described
The second oil inlet pipe 15 be provided with and prolong valve opening door 16, prolong valve opening door 16 and include valve body and spool, valve body was provided with air door regulation
The centre bore that axle 14 passes, valve body is additionally provided with the passage of logical oil, and this passage intersects with centre bore, i.e. passage is divided into by centre bore
Two parts, and the axis of this passage is vertical with the axis of centre bore, and spool is also rotatably connected in centre bore, the axis of spool
With air door regulation axle 14 axis on the same line, spool be provided with one for connecting the through hole of two parts passage on valve body,
The axis of this through hole is vertical with the axis of centre bore, and the axis of this through hole is on the extended surface of air door plane, thus in use when
When air door regulation axle 14 rotates 45 °, now half opened by air door, and on valve body, two-part passage will be by the through hole on spool
Conducting, but now flow is less；When air door regulation axle 14 rotates 90 °, now full trrottle, the through hole on spool and valve
On body, two-part passage is fully on, now maximum flow.
