Abstract

The invention discloses a novel rotor engine which belongs to the field of machine engineering. The high thermal efficiency (which can be greater than 75%) of an engine is desiderated for energy conservation and emission reduction at present. Compared with a reciprocating piston type engine, the rotor engine provided by the invention has the advantages of high efficiency, large torque, continuous power output, salability, small noise and the like. The reason of high thermal efficiency of the engine is that the thermal efficiency is calculated through expansion ratio instead of compression ratio. As the force arm of the engine is larger than the force arm of the reciprocating piston type engine of the same size, the engine has the advantage of large torque. Furthermore, three procedures of inspiration, expansion acting and exhaust are performed simultaneously, the power output is continuous. Compared with a triangular rotor engine, the engine can be easily improved into a multi-cylinder engine by increasing the number of combustion chamber devices, and the engine can be used as a device for converting chemical energy of gas or liquid fuel into mechanical energy, for example, the engine can be used as an automobile engine, used as a power source of a diesel oil power generator, and the like.

Description

New rotor engine

Technical field

The present invention relates to a kind of motor (internal-combustion engine), is a kind of New rotor engine that has obvious difference with rotary polygonal piston engine.What it was related is mechanical field.

Background technique

Using the widest motor is at present conventional engine, although because invent early, now quite ripe about the technology of this motor, but this motor still has many shortcomings, the such as thermal efficiency lower (being generally 50%-60%), easily to rock (unstable), volume larger etc.And these need the machinery of torquey engine for sport car, racing car, go-anywhere vehicle, although conventional engine still can meet the demands, it is quite high that its cost can become.

Also has a kind of more famous rotary engine: rotary polygonal piston engine.The appearance of this motor is based on the breakthrough of sealing technique at that time (success of this rotary engine means that sealing problem of the present invention can be solved equally in engineering).The same existent defect of rotary polygonal piston engine: unstable idle, the thermal efficiency are lower, make multi-cylinder and can only achieve the goal by increasing rotor at major axes orientation, like this manufacture cost can raise at double and volume larger.

In theory, rotary engine can provide higher rotating speed, the reason of people wish to make always good rotary engine that Here it is.

Summary of the invention

It is to create a kind of rotary engine that overcomes above-mentioned shortcoming that the present invention obtains object.By changing the shape of rotor symmetry, design the rotor that a kind of shape is comparatively peculiar, to adapt to various requirement.

Ignore petrolift, lubricating pump, these external meanss of camshaft of maturation of technology, the present invention is made up of three critical pieces: combusting room device, cylinder body, rotor, wherein cylinder body has comprised gas storage chamber.It is simple in structure as can be seen here.

Advantage of the present invention:

(1) thermal efficiency is high.

The present invention recently calculates the thermal efficiency by gas expansion, and gas is considered as to perfect gas, and can obtain the thermal efficiency is η=1-k ^γ-1, wherein k is expansion ratio.General expansion ratio has or lower, this has just guaranteed that the present invention obtains high thermal efficiency.

(2) moment of torsion is large.

The arm of force that acts on rotor due to high temperature and high pressure gas of the present invention is long, simultaneously, combusting room device compression gas storage chamber gas can reach more than 10 compression ratios, thereby can obtain sufficiently high air pressure after piston igniting, so this motor has larger output torque.

(3) stablize low noise.

Because rotor can be designed to rotate around its center of gravity, thereby avoid rocking of motor, made it have higher stability.

(4) plot ratio is high.

(rotor rotates one week intake valve opening time long enough, and wherein approximately having time of 5/6ths is that intake valve is opened, and more abundant thereby combustion-empty mixed gas enters, plot ratio is naturally higher.

(5) power output continuously.

This advantage is that four stroke engine is incomparable.Air inlet of the present invention, gas expansion for doing work, rotor are released these three processes of waste gas and can be carried out simultaneously, thereby the time of unpowered output is greatly reduced, and power output has higher continuity.

(6) can be modified into easily multicylinder engine.

Be different from rotary polygonal piston engine, the present invention can not increase in rotor bank object situation, and relying on increases the number of combusting room device and reach the object of making multicylinder engine, and cost and volume can significantly not increase.

Fig. 6 is a kind of two cylinder form of this motor.This figure is intended to explanation and how under situation that does not increase rotor, transform multicylinder engine as.

Embodiment

To utilize accompanying drawing 2 that working method of the present invention is described here.

Because the technology of camshaft, petrolift, lubricating pump, these devices of ignition system is very ripe, needn't make its job description here, also on accompanying drawing, do not make in detail.

Fig. 2 is divided into (a), (b), (c), (d) four parts, represents that rotor of the present invention rotates a circle and can be divided into four-stage.

Fig. 2 (a), rotor counterclockwise rotates, and its boss promotes combusting room device and axially above rotates around it, and combusting room device upwards compresses gas storage chamber gas (combustion-empty mixed gas) in rotation process.When gas storage chamber air pressure and firing chamber air pressure reach while setting difference, differential pressure reference leakage device is opened, and gas storage chamber gas starts to enter firing chamber.Meanwhile, burner port is just sealed by cylinder body, guarantees that combustion-empty mixed gas can not reveal.

Fig. 2 (b), rotor turns over after several angle, and gas storage chamber gas is all pressed into firing chamber, and combusting room device starts to reset under the effect of spring or external forced resetting means.In its reseting procedure, the minimum point A of combusting room device will contact with rotor all the time, can guarantee like this sealing.When burner port is soon opened, plug ignition.Now the intake valve of gas storage chamber is opened.

Fig. 2 (c), the pressurized gas of firing chamber act on rotor boss rotates it, and the waste gas that rotor promotes after last burning is simultaneously discharged.Gas storage chamber valve is held open, abundant to guarantee air inlet.

Fig. 2 (d), rotor substantially will be discarded and drain.High temperature and high pressure gas has also reached maximum swelling.Now gas storage chamber valve-closing.After this process completes, engine condition forwards Fig. 2 (a) to, then repeats above-mentioned Four processes.

The starting of this motor is also simple to operation, as long as it is just passable to turn several circles at outside rotor driven.

Specification specified is once made in some position below.

As Fig. 1, one section of crooked position AB of combusting room device should have identical curvature with inboard wall of cylinder block, and, when rotor boss slips over AB, combusting room device should be compressed to 0 volume gas storage chamber, now combusting room device top just contacts with gas storage chamber top, can guarantee that like this gas storage chamber gas is all pressed into firing chamber (at least also can be pressed into the overwhelming majority).

As Fig. 3, the crooked position of rotor boss effect be to guarantee that combusting room device contacts with rotor all the time in reseting procedure, guarantees sealing.Therefore, concrete shape be subject to the impact of combusting room device reset speed.If with spring make combusting room device reset, can exist a rotating speed to make in the time that spinner velocity is greater than this rotating speed cannot guarantee that combusting room device is permanently connected on rotor.So, the motor requiring for high rotating speed, suggestion is used external forced resetting means.? in, than gently, here be for to buffer function of combusting room device gently, can be because collision rebounds after its is thoroughly resetted.

Stamping Steel Ribbon should use the sealing material of low friction, high temperature high voltage resistant.
