Description
Technical field
The invention belongs to technical field of engines, are related to rotary engine, and in particular to a kind of high expansion ratio high torque turn
Sub- engine.
Background technology
Rotary engine（Rotary Engine）It is by German's Fei Jiashi wankels（Felix Wankel, 1902-
1988）Invented, therefore also known as Wankel engine (Wankel Engine), he on the basis of summarizing the achievement in research of forefathers,
The key technical problem for solving some rotary-pistons has succeeded in developing the rotary engine with practicability.Rotary engine
Air-breathing, compression, acting, exhaust stroke are completed using three-apexed rotor rotary motion, with traditional conventional engine
It moves along a straight line far different.
Rotary engine and conventional reciprocating formula engine depend on the bulbs of pressure that air gas burning generates with
Rotatory force is obtained, but in reciprocating engine, the bulbs of pressure generated in piston top surface push down on piston, mechanical force
It is passed to connecting rod, drives crank rotation.For rotary engine, the bulbs of pressure act on the side of rotor, thus by triangle
Push the center of eccentric shaft in one of three faces of rotor.This movement carries out under the force effect of two component, and one is directed to
The centripetal force of axis center is exported, the other is making the circumferential force that output shaft rotates.
The rotor of rotary engine for each revolution with regard to ignition expansion working three times, and general four-stroke engine
It is primary often to revolve the ability work done that takes two turns, therefore there is very high power-to-volume ratio.In addition, the axial operation due to rotary engine is special
Property, very high rotating speed can be reached by so that it is not needed accurate crankshaft counterbalance.Only there are two rotatable parts for entire engine, save
More than 20 a movable parts such as the inlet and outlet valve of general four-stroke engine, valve spring, camshaft, engine structure
It greatly simplifies, the possibility to break down also greatly reduces.Also include body other than above advantage, the advantages of rotary engine
Smaller, the light-weight, centre of gravity of product, vibrations are small etc..
Although rotary engine has the outstanding advantages that conventional reciprocating formula piston engine does not have, similarly exist
Some defects outstanding.It is oil consumption height first, exhaust emissions is exceeded.It is in not advise this is mainly due to rotor combustion chamber
Sleeve configuration then, flame propagation path is longer, incomplete combustion, and fuel oil and consumption of lubricating oil is caused to increase.In addition, rotary engine
Torque under low speed is small, and starting is weak；Another serious defect is the reason of rotary engine is because of structure, compression ratio
It is difficult to improve, spark ignition type can only be used, cannot fuel cannot be made using diesel oil with compression-ignited.Although Japanese Axela Inc. was once
Through increasing single turbine supercharging and twin turbocharged equal devices to rotary engine, but output power is only improved, and appropriate
Reduce exhaust emissions, but still have prodigious gap with reciprocating engine.This external-rotor engine also has sealing strip easy
The problems such as abrasion, cylinder body processing difficulties.
For the defect of the above conventional rotors engine, the present invention develops a kind of rotor of high expansion ratio high torque and starts
Machine.Engine rotor structure is improved, an interior expanding chamber is increased, the stress surface of rotor is made to increase, the arm of force of rotor increases；
The expansion ratio of engine is improved simultaneously, keeps burning abundant, is exported to which the torque under low speed can be improved and is improved engine
The thermal efficiency.
Technical problem to be solved by the invention is to provide a kind of rotary engine of high expansion ratio high torque；Transformation is started
Motor rotor structure increases an interior expanding chamber, the stress surface of rotor is made to increase, and the arm of force of rotor increases, to improve under low speed
Torque；Keep burning abundant simultaneously, engine efficiency improves.
A kind of high expansion ratio high torque rotary engine is at least made of cycloidal cylinder body, three-apexed rotor, interior expanding chamber；
It is characterized in that：Interior expanding chamber includes at least interior expansion chamber, slideway, sealing strip, slip lid, radial spring, resetting spring and reset
Spring groove；When engine works, intake stroke and compression stroke are carried out successively, when three-apexed rotor is gone at minimum working chamber
（Corresponding to the top dead centre of piston reciprocating engine）, plug ignition, high-temperature high-pressure fuel gas expansion work, promotion three-apexed rotor turn
It is dynamic；When expansion stroke is completed, exhaust valve is opened, and into exhaust stroke, then carries out second of air-breathing, compression, acting and exhaust
Stroke so moves in circles；In the expansion stroke stage, the centrifugal force suffered by slip lid overcomes the restoring force and cunning of resetting spring generation
Frictional force when dynamic makes the slip lid being pressed on originally on interior expansion chamber generate the sliding opposite with rotor motion direction, makes interior swollen
Swollen chamber is exposed to be linked together with outer expansion chamber, to expand the expansion space of combustion gas, keeps the burning of combustion gas more abundant, expansion work
More thoroughly, while gaseous-pressure directly acts on the side wall of interior expansion chamber, increases the stress surface of rotor tangential direction, increases
The arm of force makes engine export high torque.
The interior expanding chamber is located in the front end on three-apexed rotor convex surface.
The interior expansion chamber is located at below three-apexed rotor convex surface, and interior expansion chamber is the groove with intrados.
The slideway has two, symmetrical to be distributed on the notch of interior expansion chamber.
Part of the slip lid outside slideway is convex surface arc plate, the curvature of the curvature and three-apexed rotor convex surface of convex surface arc plate
It is identical.
Part of the slip lid in slideway is equipped with sealing strip.
Further, the block with flexible gasket is housed on the slip lid.
Further, for the block when slip lid slides into the distalmost end of interior expansion chamber, block is interior with interior expansion chamber
Wall contacts.
Further, when engine is not actuated, the convex surface of slip lid and remaining convex surface of rotor coincide the slip lid
Together.
Further, before ignition, slip lid is pressed on interior expansion chamber and completely enclosed interior expansion chamber for the slip lid.
Advantageous effect of the present invention is：1, by adding interior expanding chamber on rotor, significantly improve expansion ratio；2, combustion gas is swollen
Swollen more thoroughly burning is more abundant, substantially reduces oil consumption, reduces exhaust gas discharge, reduces delivery temperature；3, increase rotor by
Power face increases the arm of force of rotor, significantly improves the torque under low engine speed, keeps the starting of automobile or other dynamic power machines fast
It is prompt strong；4, rotor force of tangential direction increases, and can further improve the rotating speed of rotor.5, available power dramatically increases, and makes to turn
The power to weight ratio of sub- engine further increases；Significantly expand rotary engine application range, as automobile, unmanned plane and it is light-duty fly
Machine field.
