Description

Slidine-vane rotor engine

The present invention relates to a kind of internal-combustion engine, with Slidine-vane rotor, tangerine circle cylinder replaces the piston and the cylinder of traditional combustion engine, and engine performance is improved.

Internal-combustion engine is the major impetus source of modern industry, in industrial and agricultural production, and people's lives, communications and transportation, important effect is being brought into play in fields such as national defence.Internal-combustion piston engine is to use the most general flat a kind of pattern, by more than 100 years using and studying, the engine design of this pattern with make the quite high level that reached.Along with the continuous development of science and technology, people recognize that clearly the to-and-fro motion of piston is a big obstacle of motor progress, want further to improve the performance of motor, must change this basic structure of reciprocating motion of the pistons.The appearance of rotary engine is exactly the representative of this development trend.

Utilize the Modern Internal-Combustion Engine theory, can very clearly analyze the defective that internal-combustion piston engine exists:

One, mechanical power loss is big

Because piston moves reciprocatingly during engine operation, lose a large amount of mechanical energy, its loss amount improves and the increase of journey index with engine speed, thereby has a strong impact on the raising of engine speed and efficient.

Two, Engine torque journey sinusoidal variations

Owing to must convert the to-and-fro motion of piston the circular movement of output shaft to by connecting rod during engine operation, the moment of torsion radius is changed by sinusoidal rule.

Three, the moment of torsion dead point is arranged

It must be zero point through two moments of torsion up and down that the use of connecting rod makes piston, thereby makes firing time, and period of combustion must be very accurate.

Four, there are problems such as pinking, pre-ignition

Connecting rod, the pressure maximum time that inflammable mixture burning back produces in the requirement cylinder must be after lower dead center on the piston process, therefore, the morning and evening of firing time, the height of temperature in the cylinder, the size of compression ratio, factors such as the height of octane number all influence the work of motor, badly just pinking or pre-ignition may occur if control, and make engine cut-off, counter-rotating very causes damage.

The objective of the invention is for people provide a kind of simple in structure, power-weight ratio is big, and the rotating speed height pollutes for a short time, is suitable for the new and effective internal-combustion engine of pluralities of fuel.

The present invention is achieved in that on cylindrical rotor, evenly have four rectangular notches vertically, the notch bottom is drilled with oilhole, put into slide plate in the notch, slide plate is flexible laterally under vertical expansion bend and action of centrifugal force, rotor cylindrical body axle center is drilled with oilhole, the outside has eight road throttle grooves, and when rotor was packed the tangerine circular cylinder into, four slide plates were divided into space in the cylinder air-breathing, compression, outburst, four zones of exhaust, air-breathing district has suction port, exhaust area has the air outlet, and spark plug is equipped with in the outburst district, and the compressing area is equipped with two nozzles, end cap and bearing are equipped with in tangerine circle cylinder both sides, and rotor is fixed on tangerine circle cylinder axis.

When rotor is pressed design direction and is rotated, air-breathing, compression, outburst, four working zones of exhaust are finished work separately respectively simultaneously, the moving circle of rotor revolution, each district finishes four tasks.When 90 ° of rotor rotation, slide plate is finished once flexible, and two rotation and the stretching handle air-breathing district spaces of slide plate in tangerine circle cylinder are increased to maximum from minimum, finish air-breathing function; Simultaneously, the compressing area slide plate becomes the space, compressing area into minimum from maximum, finishes compression work; When compression work was carried out, after slide plate slipped over nozzle, just under nozzle, at this moment, nozzle was opened the throttle groove, and fuel sprays into the outburst district; The size of the arc length decision oil spout angle of throttle groove and the length of injection time.After fuel sprayed into the outburst district, spark plug produced ignited fuel high temperature and high pressure gas and promotes rotor sliding-vane, drives the rotor rotation, and when outburst district slide plate turned over relief opening, waste gas was discharged.Work simultaneously because of suction, pressure, quick-fried, Pai Si district, so Slidine-vane rotor engine is continuous operation, the moving circle of output shaft revolution is finished four work cycle, improves octuple than the work intensity of conventional, four-stroke reciprocating engine.

The ignition system of Slidine-vane rotor engine is simple more a lot of than conventional engines, the dead point because Slidine-vane rotor engine is not worked, to not being strict with firing time, as long as when engine start, once light a fire, after the engine operation, ignition system promptly quits work, but later ignition operation leans on the heat of fuel combustion to go down with regard to continuous operation.

The lubrication system of Slidine-vane rotor engine is quite simple, the other end at engine output shaft increases an oil storage end cap, wherein add lubricant oil, the clockwise sub-axle center of lubricant oil oilhole flows into rotor axis, the centrifugal force that produces when relying on rotation gets rid of lubricant oil in front and back bearings and vane slot and the tangerine circle cylinder.

The cooling system of Slidine-vane rotor engine has used the type of cooling in the cylinder of the present invention.In oval cylinder compressing area two nozzles are housed, one is used for oil spout, and another is used for water spray.When engine operation, the generation high temperature and high pressure gas because fuel constantly burns, make outburst district temperature news speed give birth to high, if adopt the outer water cycle type of cooling of the cylinder of conventional engines, rate of cooling is slower, can not adapt to the cooling requirement of Slidine-vane rotor engine in the continuous explosive combustion in outburst district, simultaneously, heat-energy losses is very big.Adopt the type of cooling in the outburst of the present invention district cylinder, promptly when outburst district temperature surpasses design standard, temp autocontrolled nozzle sprays into the outburst district with cooling water, and water absorbs heat and reduces outburst district temperature, simultaneously, water is vaporized, become water vapor, volume increases, and outburst district internal pressure is increased, output power increases, and reaches the dual purpose of cooling and synergy.

Owing to adopted such scheme, made Slidine-vane rotor engine have following advantage:

1, become the circular movement of the to-and-fro motion of piston into rotor, thereby mechanical power loss is reduced, moment of torsion increases, and output power improves.

2, power-weight ratio simple in structure increases.

3, thoroughly eliminate pre-ignition, reduce pinking and surface ignition.

4, be suitable for pluralities of fuel.

5, ignition system is simple, only needs once to light a fire when starting.

6, motor long service life, at the bottom of the rate of fault, maintenance and debugging is simple.

7, rotating speed height.

8, fuel thermal efficiency height.

9, freely use exhaust turbine pressuring technology.

10, exhaust emission pollution is little.

Do further to count bright below in conjunction with drawings and Examples to the present invention.

Fig. 1 is the fundamental diagram of Slidine-vane rotor engine, and Fig. 2 is the axial sectional view of complete machine, and Fig. 3 is the rotor axial sectional view, and Fig. 4 is the slide plate three-view diagram, and Fig. 5 is the lubricant oil end cap, and Fig. 6 is a front cover, and Fig. 7 is an end cover.

Fig. 1 rotor rotates counterclockwise, and is air-breathing district successively along the space in the intakeport tangerine circle cylinder, the compressing area, the outburst district, exhaust area, corresponding slide plate is respectively A, B, C, D, when slide plate A when Fig. 2 position forwards Fig. 3 position to, the breathing space maximum is finished breathing process, space, compressing area minimum is finished compression, outburst district space maximum, outburst finishes, the exhaust space minimum, and waste gas is discharged.The rotor revolution is finished a work cycle for moving 90 ° later on.Need to prove: compression process and oil spout, the water spray process is carried out simultaneously, promptly opens after the oil spout and makes ignition, and burning is carried out continuously, therefore, need only once light a fire when starting.Start mode can adopt external force to drag, and also can adopt and spray into the compression volume across-the-line starting from the compressing area, thereby make start mode simple, and is convenient, flexibly.

Because Slidine-vane rotor engine does not have the moment dead point, problems such as pre-ignition can freely be used exhaust turbine pressuring technology, make engine power, and efficient further improves.
