Description
Technical field
The present invention relates to one kind can be with the long-life aviation rotary engine of full combustion heavy oil.
Background technique
In currently available technology, for some rotary engine due to poor air-tightness, gas leakage is serious, and rotary engine is caused to light a fire
Difficulty, work efficiency drop.Some and lubricant effect are poor, when running, since insufficient lubrication will cause inner surface of cylinder block and end
The quick frictional dissipation of lid rubbing surface, serious frictional dissipation shorten rotary engine service life, increase use cost.Example
As application No. is described in a kind of end sealing of rotary engine of CN201621059478.2 and lubricating arrangement patent for the patent No.
Diaphragm seal, two pieces of outside is rigid seal piece, and centre is flexible sealing fin, and when engine operation, flexible sealing fin is not wear-resisting
Damage, long time running can lose lubricant effect.It is living with roller that application No. is a kind of rotary engine of CN201520785291.X
Roller described in the patent of plug, due to rotor housing inner wall Zhou Chang great, roller perimeter is small, and roller revolving speed is high, when long
Between operate when roller can be seriously worn, so that engine is lost air-tightness.In above two patents, rotor all can be violent with end cap
Friction makes end cap generate frictional dissipation, leads to end cap damage replacement, increases maintenance and use cost.
Summary of the invention
The object of the present invention is to provide it is a kind of can sufficiently be atomized, combusting heavy oil fuel, energy saving, air-tightness is good, lubrication
Effect is good, the low rotary engine of use, maintenance cost.Solve the above problem present in background technique.
The technical scheme is that this heavy oil aviation rotary engine by rotary engine body, can be axially and radially
Scribing, lubricating oil centrifugation lubricating system, mixed gas heavy oil injector and the end cap patch composition of elastic compensating sealing.
Can axially and radially elastic compensating sealing scribing be made of the two panels scribing that fits together, above two panels scribing
There is the slot for placing spring, the spring of the inside supports two scribings simultaneously, provides the axial elastic force of both direction for scribing, makes to draw
Piece can be axially fitted tightly over above rotary engine end cap.There are oilhole, lubricating oil on each apex angle of three-apexed rotor
Spring is placed inside hole, provides radical elasticity for two panels scribing, two panels scribing is made to can be closely adhered to the inner surface in cylinder body.It can
With the scribing that axially and radially elastic compensating seals, keep rotary engine air-tightness good.Oilhole is being centrifuged lubricating oil
It under the action of power, guides between the binding face of two scribings, centrifugal force oozes out lubricating oil from the binding face of two panels scribing, is
Rotor housing and scribing provide lubrication, and rotary engine durability can be improved in good lubrication.
Mixed gas heavy oil injector is made of gas chamber, air valve, fuel injector.Mixed gas heavy oil injector is mounted on rotary engine
On cylinder body and on end cap, when rotor compression, the air valve for mixing gas heavy oil injector is opened, and gas compressed enters mixed gas heavy oil spray
Emitter gas chamber.Compression finishes, and air valve is closed, and pressure-air is stored in inside the gas chamber of mixed gas heavy oil injector.At this moment, fuel injector
Heavy oil is sprayed into inside toward gas chamber.As rotor continues to rotate, mix gas heavy oil injector entrance again with rotary engine pressure
The connection of contracting chamber, compression chamber the inside air are in low-pressure state, mix gas heavy oil injector air valve and open, the high pressure gas of gas indoor storage
Body is sprayed into rotary engine together with heavy oil therein is mixed in.Under high-speed flow impact, heavy oil is sufficiently atomized, and makes rotor
Heavy oil inside engine chamber being capable of full combustion.The pressurized gas source of mixed gas heavy oil injector is in rotary engine pressure
Contracting stroke itself does not need other auxiliary air compressor, simplifies rotary engine structure, reduces the weight of rotary engine
Amount.
End cap patch is a thin slice for being attached to rotary engine end cap rubbing surface.When rotary polygonal piston engine is done work, end
Lid long-time and three-apexed rotor friction, end cap can be generated and be seriously worn.It is bonded a patch in end cap rubbing surface, rotates rotor
When with patch friction, no longer with end cap direct friction, end cap no longer wears.When patch is worn, end cap patch can be replaced, is not had to
Rotary engine end cap is replaced, rotary engine use cost is reduced.
