Suction port and relief opening is provided with near firing chamber on the circular cylinder body part of annular cylinder body, intake valve baffle plate and exhaust valve baffle plate are installed after assembling wherein, the discoid cylinder body part of annular cylinder body both sides is provided with radial opening slot at the corresponding position of suction port and relief opening, in order to place the moving direction of inlet and exhaust valve baffle plate and restriction inlet and exhaust valve baffle plate.The outside at the opening slot place of the discoid cylinder body part of annular cylinder body both sides is provided with the two row rollers consistent with direction of slotting, the axis of roller is axially consistent with annular cylinder body, two row's roller minimal-contact distances equal the thickness of inlet and exhaust valve baffle plate, valve shield can move up and down between two row's rollers (relative to axle center) therefore inlet and exhaust valve baffle plate easily can move along opening slot and not have stress to contact with fluting.
Described inlet and exhaust valve baffle plate is divided into intake valve baffle plate and exhaust valve baffle plate, and they have intake and exhaust functions concurrently and form independent stroke space for work by combustion, exhaust, the effect of air inlet and compression.Intake valve baffle plate is similar with exhaust valve baffle shapes, is arranged symmetrically with and burner ends, and the valve shield of the first process of rotor is exhaust valve baffle plate, laggard mistake be intake valve baffle plate.Valve shield is made up of baffle plate and valve two-part, also can as one, valve shield upper end is rectangle, and below rectangle, there is the long pin slightly higher than piston at two ends, fill up the space of the fluting on two side discs cylinder blocks when the effect of long pin is valve shield rise, prevent gas from being run out of by annular cylinder body.Outstanding projection is had in the both sides of baffle plate or side, it is external that the projection that valve shield is arranged on annular cylinder body backboard both sides or side protrudes from annular cylinder, projection is perpendicular to annular cylinder body, it can install roller or bearing, and be nested in the track in track plate in order to control valve shield rise and to decline.Valve is arranged on the side of baffle plate circumference, when baffle plate valve when extreme higher position (the relative center of circle) blocks valve port, valve closure, when baffle plate is descending, valve is opened gradually, valve width is equal with piston width in rotor, is less than barrier width, and valve lower end is circular arc, there is lower edge to seamlessly transit to upper end, reduce intake and exhaust resistance.Valve shield is operated in hot environment, but hot working face is without high frictional force, can use High Performance Adiabatic heat resistant material.
Rise to realize valve shield in the suitable time and decline, the present invention is provided with the track plate controlling valve shield lifting, track plate together rotates with rotor, track plate is provided with continuous groove both tracks, channel section shape is rectangle, the projection of valve shield both sides or side (can add roller or bearing is collectively referred to as bearing roller) just in time embeds in it, valve shield is because be subject to the restriction of annular cylinder body upper roller, can only radially move, when grooved tracks produces active force to projection, projection controls the lifting of valve shield at the component of radial direction.Can calculate valve shield according to the shape of piston should when landing, thus can calculate the track of continuous groove, because piston is level and smooth protruding, so the trail change of groove is level and smooth, is roughly divided into two circular arcs, the large radius of two one, circular arc radiuses is little, is linked by smoothed curve.Intake valve baffle plate or exhaust valve baffle plate calculate known so can control its lifting by same grooved tracks, but intake valve baffle plate and the unavailable grooved tracks of exhaust valve baffle plate control lifting, and both grooved tracks are just in time symmetrical arranged, both will certainly be made to have crossing part by track, the place of intersecting can make the projection of valve shield enter the track of mistake, the cross section of these two grooved tracks is set to width and the degree of depth is different for this reason, groove dark person width is narrower, like this, thicker projection does not enter narrower grooved tracks, longer projection also can not enter more shallow grooved tracks.In order to make the more balanced subduction wearing and tearing of active force acting on valve shield, a track plate should be respectively set in annular cylinder body both sides, be subject to can arranging more than one projection in inlet and exhaust valve baffle plate side when track plate controls to be conducive to like this reducing wear when only having side, also projection can be set in inlet and exhaust valve baffle plate both sides, be subject to track plate simultaneously and control.
The annular cylinder body of described piston rotary engine is provided with firing chamber, below burning chamber shell by discoid cylinder body part and inlet and exhaust valve baffle plate round space be firing chamber, the front and back position of flammable pressurized gas at piston is switched in the effect of firing chamber, exchanging stroke space makes motor can cycle four-stroke work, also has the effect of ignition-powering.Compression stroke piston in latter stage promotes a large amount of fresh air in its front or combustible gas enters firing chamber, after the piston of both sides, firing chamber through intake valve baffle plate be in extreme lower position (the relative center of circle), piston and intake valve baffle plate define independent confined space and carry out pressurized air, but fresh air at this moment or combustible gas are in the front of piston movement, in order to make the gas of compression move to the rear of piston, so that ignition-powering continues to promote piston, move ahead will by the gas exchanges in piston front to piston rear, its method is: piston advanced person cross exhaust valve baffle plate at piston by rear beginning descending along piston rear surface (being at this moment in extreme lower position through intake valve baffle plate afterwards), both contact but piston backside gas and pressurized gas are completely cut off without active force (being ensured by track plate), piston continues to move ahead, because front space is too little, piston front gas by firing chamber above void spaces move to piston rear, in this process, if piston nose touches intake valve baffle plate, then intake valve baffle plate can rise along piston front surface, contact and without active force (being ensured by track plate), combustion chamber gases place-exchange constipation bundle is gone out when piston is capable.A very important benefit of this process is the increase in the action of turbulent flow of inflammable mixture, this is to the velocity of combustion important of flame, therefore the rotary engine of this invention can carry out homogeneous combustion, improves engine power performance thus improves its fuel economy.In order to strengthen the flowing state of burning indoor gas further, engine design of the present invention firing chamber stream condition control gear: the guide plate be arranged in firing chamber also can increase the turbulence scale of pressurized gas, described guide plate is arranged on top of combustion chamber void spaces can not affect passing through of piston, guide plate is by the cylindrical hole connection control device of burning chamber shell, can turn an angle around cylindrical hole, control the angle of guide plate, several guide plate can be had, it can not use High Performance Adiabatic and heat resistant material by strong effect of stress, being provided with seal ring in cylindrical hole prevents the pressurized gas in firing chamber from spilling cylinder block.The technology of this important raising fuel economy of stratified mixture combustion can also be realized in rotary engine of the present invention, and more easily realize, its way of realization has multiple, by controlling the angle of guide plate and controlling the fuel injection beginning time of oil sprayer, oil sprayer is arranged on top of combustion chamber one end near air flap, ignition mechanism is arranged on top of combustion chamber one end by inlet and exhaust valve baffle plate, oil sprayer oil spout when piston compression gas will enter firing chamber, at this moment the air before piston in small distance defines pressurized gas due to the piston compression of high speed rotating, and the fresh wage near intake valve baffle plate place is in less compressive state, its oil bundle end of the fuel oil now sprayed into just in time is positioned at the pressurized gas of small distance before piston, and oil bundle end only has a small amount of fuel oil, and containing great amount of fuel oil in the low-pressure gas of intake valve baffle plate, along with piston moves ahead, piston rear portion forms relative vacuum degree, first pressurized gas in the anterior small distance of piston enter top of combustion chamber due to pressure reduction and enter piston rear portion, form weak mixture, along with piston to continue to move ahead in firing chamber near the high concentration mixed gas of intake valve baffle plate along firing chamber end face press-in piston rear portion, high concentration inflammable mixture is formed near spark plug, and away from forming low density inflammable mixture near spark plug, stratified mixture combustion just can realize.Also secondary fuel injection technology can be passed through, oil sprayer sprays a certain amount of fuel oil of people when piston enters firing chamber, once oil is sprayed again time in the middle part of piston moves to firing chamber, first time oil spout can form thin inflammable mixture at piston rear portion, the high concentration inflammable mixture that second time oil spout is formed moves near spark plug along piston head, near forming spark plug, mixture strength is high, the stratified mixture combustion gas that the local mixture strength away from spark plug is low, and plug ignition forms stratified mixture combustion.Therefore motor combustion chamber case of the present invention can be installed multiple oil sprayer or and igniter, to realize multiple burning Morphological plasticity duty requirements.
The ring-shape cylinder interal part of described annular cylinder body can arrange assisted gas doorway between two adjacent firing chambers as required, and when only having a firing chamber, assisted gas doorway is between two valve shields away from firing chamber.Doorway is provided with auxiliary valve to assisted gas, auxiliary valve is made up of the bearing roller on the circular hole of the outstanding minor axis of auxiliary valve principal part, auxiliary valve principal part both sides or processing, auxiliary valve control arm and control arm, be divided into auxiliary exhaust door and auxiliary intake valve, open when auxiliary exhaust door gas is thereunder the gas of exhaust stroke, piston will by this valve before close; Open when auxiliary intake valve gas is thereunder the gas of intake stroke, close at the end of intake stroke.Above-mentioned auxiliary valve is because high temperature face contacts without strong stress, so can use High Performance Adiabatic heat resistant material.Auxiliary valve is fixed on annular cylinder body, and can open in annular cylinder body around the circular hole of the outstanding minor axis of these auxiliary valve principal part both sides or processing, the object of opening in annular cylinder body is thrust and the increase sealing that can bear cylinder block inner high voltage gas when auxiliary valve is closed.The opening and closing of auxiliary valve do not need to think the accurate like that control of inlet and exhaust valve baffle plate, therefore its control mechanism is relatively simple, by outmost turns on track plate, gear can be installed, annular cylinder body is provided with train of reduction gears, gearwheel engagement on gear on track plate and train of reduction gears high speed axle, drive the small gear on high speed shaft, small gear engages with gearwheel on lower velocity shaft again, if the rotating speed of lower velocity shaft is identical with engine speed, it is output shaft, otherwise continue to decelerate to start rotating speed identical, output shaft is provided with cam, bearing roller on the control arm of auxiliary valve opens auxiliary valve under the effect of cam, valve-closing is made by spring action in control arm under all the other states, similar with the working principle of conventional piston engine valve, also track can be set up on track plate, by the displacement of orbits controlling bearing roller, thus control the opening and closing of auxiliary valve.
The compression ratio of piston rotary engine of the present invention can be controlled by the change shape of piston and the size of firing chamber, and firing chamber is larger, and when lighting, gas volume is larger, and compression ratio is less; Piston volume is less, and when lighting, in firing chamber, gas volume is larger, and compression ratio is less, and the motor of therefore this invention forms different compression ratios by the shaped volumes changing firing chamber and piston, and various fuel therefore can be used for work by combustion.If think change one the discharge capacity of ready-made motor and/or compression ratio only need the rotor more reengined and track plate, can also realize by changing burning chamber shell.Because the operation change of the less inlet and exhaust valve baffle plate be mated of piston volume is fiercer, therefore, piston when intake valve baffle plate goes upward to peak when exhaust valve baffle plate comes downwards to minimum point is optimal selection.
And the rotary engine of invention also achieves motor when motor that other motors not easily realize becomes Displacement Technology and automobile temporary stopping easily stopping work by combustion fast, need when starting, to make engine combustion acting start-stop technology fast, and engine start/stop technology is had new implication: be no longer to stall, but start to be rotated further but not consume fuel.When multiple motor of the present invention arranged side by side be combined in high power engine when needs are some or multiple-motor stop doing power reduce oil consumption time, as long as all valve shields are moved to peak position (relative to axle center) and make the projection of inlet and exhaust valve baffle plate de-orbit dish control, auxiliary valve is in closed condition and departs from the control of cam or track plate, although at this moment rotor is rotated further, but do not have the process of pressurized gas, gas in cylinder can rotate along with the rotation of rotor, gaseous state does not change, thus engine rotation but do not need fuel, rotational resistance is minimum.Same reason when automobile needs interim stopping in order to saving fuel oil should close the fuel delivery to motor, all inlet and exhaust valve baffle plates are moved to extreme higher position (relative to axle center) simultaneously and make the projection of valve shield de-orbit dish control, auxiliary valve closed condition also departs from the control of cam or track plate, rotor is rotated further in annular cylinder body, do not cause the change of cylinder charge state, thus rotational resistance is minimum, when motor needs work by combustion, the projection of all inlet and exhaust valve baffle plates is introduced in the track of track plate, make track plate continue to control inlet and exhaust valve baffle plate and complete normal work, and make auxiliary valve be in by cam production state, because rotor still has larger kinetic energy, all can the fresh wage of Fast Compression, light acting, motor is enable to realize fast starting, when automobile needs long period temporary shut down, in order to prevent engine speed lower than minimum startup rotating speed, micro-machine (or starting electrical machinery) electrical power job can be introduced and drive engine revolution, the rotating speed of motor is remained on minimum startup rotating speed.Said process needs accessory as air-conditioning, oil hydraulic pumps etc. depart from the driving of motor, can the driving wheel of accessory be driven to arrange separately inventive piston rotary engine, not with rotor synchronous axial system constantly, and to introduce and the same clutch mechanism of gearshift to the driving of the driving wheel of accessory whether realizes piston rotary engine, when needing to drive accessory, driving wheel transmits the torque that motor exports, and when not needing to drive, driving wheel does not transmit the torque that motor exports.
In order to realize said process, the projection of described inlet and exhaust valve baffle plate is installed one can along projection axial movement of bearing roller, projection curtailment is now with in embedding people's grooved tracks, when bearing roller stretches people in groove, bearing roller can move in grooved tracks, form grooved tracks thus to the control of bearing roller and then the movement controlling inlet and exhaust valve baffle plate, the cylndrical surface of bearing roller there is the cylinder ring of a circle projection, when inlet and exhaust valve baffle plate moves to extreme higher position, the cylinder ring of bearing roller cylndrical surface upper process enters in the draw-in groove corresponding with its shape, this card is wiped can moving axially along projection, and then drive bearing roller to move axially, a post pin is connected with draw-in groove, post pin moves with draw-in groove, when draw-in groove moves to annular cylinder body control bearing roller also to annular cylinder body move make bearing roller de-orbit dish control, prevent inlet and exhaust valve baffle plate from moving down with in the post holes on the post pin insertion inlet and exhaust valve baffle plate of draw-in groove movement simultaneously.Draw-in groove is fixed on annular cylinder body, and by motor or hydraulic driving, and draw-in groove is fixed on the up highest position of projection.Because only have inlet and exhaust valve baffle plate to move to extreme higher position just can be de-orbited the control of dish, otherwise piston will form movement interference with inlet and exhaust valve baffle plate, have multiple method that the valve shield dish that de-orbits is controlled, will talk about in concrete enforcement.
The control arm of auxiliary valve is directly connected with auxiliary valve, on control arm, linking springs makes auxiliary valve be in normally off, when needing in rotor turns process to close auxiliary valve always, control arm need depart from the control of cam, control arm is made for this reason and axially can move freely T-shaped control arm at annular cylinder body, and be not directly integrated with auxiliary valve principal part, T-shaped box is processed in the position connecting auxiliary valve principal part, T-shaped control arm is divided into transverse arm and vertical arm, and T-shaped box is also divided into lateral part and vertical part.T-shaped box lateral part directly connects and auxiliary valve principal part, T arm can be placed in T-shaped box, transverse arm is positioned over T-shaped box lateral part, vertical arm is positioned over the vertical part of T-shaped box, the vertical arm of the more T-shaped bar of vertical part of T-shaped box is wide, the lateral part of T-shaped box is consistent with the transverse arm width of T-shaped arm or radius, so T-shaped arm can only along the transverse shifting certain distance of T-shaped box.When not needing T-shaped arm to be subject to cam production, T-shaped arm is moved a certain distance (being greater than cam width) bearing roller along transverse arm and depart from cam production, when the T-shaped arm of needs cam production, control the working position of T-shaped arm along transverse arm movement.The movement of T-shaped arm is subject to the restriction of draw-in groove, this draw-in groove is fixed on annular cylinder body, its transverse shifting is driven by motor, the vertical arm of T-shaped arm is clipped in wherein stirs montant transverse shifting, or the restriction that one end of T-shaped arm transverse arm is subject to draw-in groove makes it can move along transverse arm, makes T-shaped control arm enter cam production or the cam production that comes off.Said process needs the respective carter dish position under auxiliary valve is closed condition to carry out, and has multiple method that auxiliary valve is de-orbited and coils control, will talk about in concrete enforcement.
Piston rotary engine of the present invention has higher requirements to sealing, wherein there is having of sealing requirements: the annular position that a annular inner cylinder body contacts with annular cylinder body, its encapsulating method is the ring position contacted with annular cylinder body at annular inner cylinder body is processed circular groove, can process on annular inner cylinder body or annular cylinder body separately, also can process at both corresponding positions simultaneously, the sealing that machined grooves is formed on rotor cylinder block and annular cylinder body is simultaneously better, prevent annular seal circle in a groove, multiple tracks groove can be added and placed multiple seal ring, the material that should high resistant should be used hot the seal ring of outmost turns.Surface of contact between all the other seal rings should have good lubrication; The sealing of b piston and annular cylinder body, piston interior rotation of annular cylinder body carries out pressurized gas, work by combustion, air inlet and exhaust, therefore gas can not be flowed out in other stroke space by the surface of contact in piston and annular cylinder body, so piston should be sealed and matched with annular cylinder body internal surface, two flat sides set of piston contact all the time with annular cylinder body but unstressed, therefore can go out by the groove of extreme lower position to extreme higher position at the both sides plane machining of piston, in order to place Stamping Steel Ribbon, many grooves and Stamping Steel Ribbon can be set.The top of piston contacts with the annular surface of annular cylinder body internal surface, groove can be processed vertically at piston head and place Stamping Steel Ribbon, wiped off by valve shield for preventing Stamping Steel Ribbon, the position starting to contact with piston in valve shield can be processed smooth curve, should say that the Pocket Machining of the piston head placing Stamping Steel Ribbon is chevron shaped in order to place Stamping Steel Ribbon in firing chamber disengaging, Stamping Steel Ribbon is also processed as man type, and the following two legs of chevron shaped Stamping Steel Ribbon is embedded into the part above in herringbone grooves and contacts with the annular wall sealing of annular cylinder body inwall; Sealing between c valve shield and annular cylinder body, valve shield annularly in the radial opening slot on annular cylinder body of cylinder block relatively axle center move up and down, confined space is formed with piston or below above when valve shield is descending, therefore valve shield seals with opening slot and contacts, several radial grooves can be processed in opening slot, place Stamping Steel Ribbon in groove, form sealing effect.The sealing of d valve shield and auxiliary valve and corresponding valve port is also very important, and the sealing between them has the surface of contact of clutch close to the curved face type construction complete carving type by them.
Described rotary engine has engine housing; the effect of engine housing fixes, supports and protect piston rotary engine; engine housing and annular cylinder body are rigidly connected; and can air inlet-outlet pipe be fixed thereon, fuel pipe, sensor and wire etc.; another important function of engine housing is the normal operation of protection track plate and valve shield; because the cooperation of track plate and valve shield epirelief post belongs to precision-fit, can not have in foreign material injection, need to do suitable encapsulation process.Engine housing by miscellaneous part parcel within it, the output shaft externally connected is spilt near axle center, because track plate will stir ambient air rotation when high engine speeds is rotated, engine housing by the gas seal around track plate in its vicinity, deceleration track plate agitation air rotates the energy loss caused, in addition, engine housing is provided with cold wind suction port and hot blast air outlet, the gas rotated in engine housing will go out output degree of vacuum at suction port and will suck in engine housing through filtered air, the gas rotated in engine housing will produce high pressure in air outlet and be discharged to air, or for air-conditioning and engine combustion, when cooled engine works by this process, the temperature of body raises.

Rise to realize valve shield 1 in the suitable time and decline, piston rotary engine of the present invention is provided with the track plate 12 controlling valve shield 1 and be elevated, track plate 12 together rotates with rotor 2, track plate 12 is provided with continuous grooved tracks 267, grooved tracks 267 sectional shape is rectangle, the projection 35 of valve shield 1 side or the clutch shaft bearing roller 36 on it just in time embed in it, valve shield 1 is because be subject to the restriction of annular cylinder body 13 upper shed groove bearing 25, can only radially move, grooved tracks 267 pairs of projections 35 produce the lifting of the radial component control valve shield 1 of active force.The suitable landing of valve shield 1 can be calculated according to the shape of piston 30, thus the track of continuous grooved tracks 267 can be calculated, because piston 30 is level and smooth protruding, so, the track transitions smooth of grooved tracks 267, be roughly divided into two circular arcs, the large radius of two one, circular arc radiuses is little, by smooth curved transition.Calculate that known all intake valve baffle plates 101 or exhaust valve baffle plate 102 can control its lifting by same grooved tracks 267, but intake valve baffle plate 101 and the unavailable grooved tracks of exhaust valve baffle plate 102 control lifting, calculate that grooved tracks 267 almost symmetry drawing both is arranged, will certainly be that both tracks have crossing part like this, the place of intersecting can make the projection 35 of valve shield 1 enter groove 267 track of mistake, for this reason, the cross section of these two grooved tracks 267 is set to width and the degree of depth is different, grooved tracks dark person width is narrower, the shallow person's wider width of grooved tracks, corresponding projection 35 elder diameter is little, short person's diameter is large, like this, thicker projection 35 does not enter narrower grooved tracks 267, longer projection 35 also can not enter more shallow grooved tracks 267.In order to make the more balanced subduction wearing and tearing of active force acting on valve shield 1, should respectively arrange a track plate 12 in annular cylinder body 3 both sides, acting in conjunction is in projection 35.The track plate 12 of both sides can control intake valve baffle plate 101 and exhaust valve baffle plate 102 simultaneously, also can control intake valve baffle plate 101 by side track plate 12, and opposite side track plate controls exhaust valve baffle plate 102, and the former is called that both sides control type the latter claims single side control type.
Scheme 1: both sides control type: described valve shield 1 both sides are respectively processed with one or more projection 35(on it can add clutch shaft bearing roller 36), both sides projection 35 is subject to the control of both sides track plate 12 simultaneously, when track plate 12 rotates, valve shield 1 radially moves up and down, but the mobile behavior of intake valve baffle plate 101 and exhaust valve baffle plate 102 can not only by an orbits controlling, so track plate 12 has two groups of variform intake valve tracks 26 and exhaust valve track 27, and these two tracks have intersection, in order to the projection 35 reduced on this coincidence intake valve baffle plate 101 and exhaust valve baffle plate 102 is arranged on different heights position, the part that grooved tracks 267 can be made like this to overlap is an intersection point just.
Scheme 2: single side control type: described valve shield 1 side process one or more projection 35(or its on add clutch shaft bearing and roll 36), opposite side does not then have, this valve shield 1 is only subject to the control of side track plate 12, when when only having a projection 35, valve shield 1 moves up and down, the wearing and tearing of projection 35 and grooved tracks 267 are accelerated, and easily produce dislocation, should be strengthened it in the fixing of annular cylinder body 3 axis and lubrication for this reason, at this moment the grooved tracks 267 on the both sides track plate 12 after installing is asymmetric, side is the track plate 12 controlling intake valve baffle plate 101, it only has intake valve track 26, opposite side is the track plate 12 controlling exhaust valve 102, it only has exhaust valve track 27, also can process two or more projection 35 in side again, wearing and tearing when projection 35 and grooved tracks 267 move up and down reduce.At this moment track plate 12 side controls intake valve baffle plate 101 side and controls exhaust valve baffle plate 102, but same track plate 12 there will be two or more pieces grooved tracks 267.
The effect of firing chamber 6 be Commutative Contraction gas piston 30 front and back position, exchange stroke space and make motor can cycle four-stroke work, also have the effect of oil spout, ignition-powering.Before compression stroke piston in latter stage 30 promotes, a large amount of fresh air enters firing chamber 6, now intake valve baffle plate 101 is in extreme lower position, piston 30 and intake valve baffle plate 101 define confined space and continue pressurized air, but the front that fresh pressurized gas at this moment moves at piston 30, in order to the rear making the gas of compression transfer to piston 30 moves ahead so that ignition-powering continues to promote piston 30, needs will by the gas exchanges in piston front to piston 30 rear, its method is: exhaust valve baffle plate 102 is descending along piston 30 rear surface by rear beginning at piston 30, both contact but piston 30 backside gas and pressurized gas are completely cut off without active force (being ensured by track plate), piston 30 continues to move ahead, because piston 30 front gas pressure constantly increases, piston 30 rear forms certain vacuum degree, pressurized gas partly move to piston 30 rear by firing chamber 6 is spacious above, in this process, if intake valve baffle plate 101 is touched in piston 30 front end, then intake valve baffle plate 102 can rise along piston 30 front surface, contact and without active force (being ensured by track plate), when piston 30 top row goes out firing chamber 6, atomisation station exchanges constipation bundle.A very important benefit of this process is the increase in the turbulence scale of live gas, and this is to the velocity of combustion important of flame.In order to strengthen the flowing state of gas in firing chamber 6 further, engine design of the present invention firing chamber stream condition control gear, it is made up of guide plate 18 guide plate connecting rod 17 and refluence hole 16 and electric controller, at the top of firing chamber 6, some guide plates 18 are installed, guide plate 18 is for strengthening the flowing state of gas when atomisation station exchanges, described guide plate 18 is arranged on top, firing chamber 6 void spaces can not affect passing through of piston 30, guide plate 18 is by the guide plate connecting rod 17 connection control device in the water conservancy diversion plate hole 16 of install combustion room housing 15, guide plate 18 can turn an angle around water conservancy diversion plate hole 16, control the angle of guide plate 18, several guide plate 18 can be had, it can not use High Performance Adiabatic and heat resistant material by strong effect of stress, guide plate connecting rod 17 and water conservancy diversion plate hole 16 process diameter different two sections or multistage, and seal groove can be processed on guide plate connecting rod 17, seal ring is installed, cylinder 301 is spilt to prevent the pressurized gas in firing chamber 6.Burning chamber shell 15 is provided with how some spark plugs 20 and spark plug 19, also can without oil sprayer or spark plug, or all do not have, if be provided with multiple oil sprayer or and spark plug, then oil sprayer or and spark plug can burning chamber shell 15 circumferentially or and axial distribution; Like this can by regulating oil spout order, injection time, oil spout number of times, fuel injection quantity and firing time, ignition order etc. realize motor under different operating mode with optimum performance work.
The circular cylinder body part 13 of described annular cylinder body 3 can arrange auxiliary valve 4 between two adjacent firing chambers 6, be divided into auxiliary exhaust door 402 and auxiliary intake valve 401, open when auxiliary exhaust door 402 gas is thereunder the gas of exhaust stroke, piston 30 will by this valve before close; Open when auxiliary intake valve 401 gas is thereunder the gas of intake stroke, close at the end of intake stroke.Above-mentioned auxiliary valve 4 is because high temperature face contacts without strong stress, so can use High Performance Adiabatic heat resistant material.Described auxiliary valve 4 is by auxiliary valve principal part 38, and the circular hole 42 of the minor axis 41 that auxiliary valve control arm 39, second bearing roller 40 and auxiliary valve principal part 38 both sides are given prominence to or processing forms.The circular hole 42 that minor axis 41 is fixed in hole corresponding with it on annular cylinder body 3 or auxiliary valve principal part 38 both sides process that the both sides of auxiliary valve principal part 38 are given prominence to is fixed on minor axis corresponding with it on annular cylinder body 3, auxiliary valve 4 can turn an angle around being fixed on hole or minor axis on discoid cylinder body part 14, auxiliary valve principal part 38 is because will contact high-temperature gas and will need to ensure sealing by piston 30 below it, so the part of auxiliary valve principal part 38 contact piston 30 is processed as the curvature the same with circular cylinder body part 13 internal surface, have to process with the part of circular cylinder body part 13 clutch in auxiliary valve principal part 38 simultaneously and carve type structure, the sealing of auxiliary valve 4 when closing can be increased.The opening and closing of auxiliary valve is defined when auxiliary valve is rotated around the minor axis 41 processed or circular hole 42, auxiliary valve control arm 39 one end connects auxiliary valve principal part 38 one end and connects effect that the second bearing roller 40, second bearing roller 40 is subject to cam 43 or single-track 49 and produce displacement and drive auxiliary valve control arm 39 that auxiliary valve is opened and closed.
The opening and closing of auxiliary valve 4 do not need accurate control as valve shield 1, and therefore its way of realization is relatively simple, and its way of realization can be divided into two kinds substantially: train of reduction gears type and direct control type.
Scheme 3: train of reduction gears type: outmost turns installs gear 44 on track plate, annular cylinder body 3 installs train of reduction gears, high speed shaft gearwheel 45 on the high speed gear shaft of the gear 44 on track plate 12 and the train of reduction gears on annular cylinder body 3 engages, high speed shaft small gear 46 on high speed gear shaft engages with the lower velocity shaft gearwheel 47 on low speed gear axle again, like this, until the rotating speed of reduction gear lower velocity shaft is identical with rotor 2 rotating speed, at this moment on lower velocity shaft, cam 43 is installed, the second bearing roller 40 of connection auxiliary valve control arm 39 can be made when cam 43 rotates to be subjected to displacement to control the opening and closing of auxiliary valve 4, auxiliary valve 4 is opened under the effect of cam 43, acting on auxiliary valve control arm 39 by spring 48 under all the other states makes auxiliary valve close, similar with the working principle of conventional piston engine valve, it should be noted that gear 44 can be cylindrical gears also can be cone gear, when gear 44 is cylindrical gears, train of reduction gears is Cylinder Gear wheels, when gear 44 is cone gear, train of reduction gears is cone gear group, simultaneously Cylinder Gear wheels type gear 44 if internal gear then internal gear 44 must protrude from track plate 12 and make track plate must away from circular cylinder body 3 certain distance, cone gear group does not then need track plate to leave circular cylinder body 3 one segment distance (track plate has plenty of beneficial and necessary in the valve shield control gear hereafter mentioned away from circular cylinder body certain distance) more, when gear 44 is external gear, gear 44 first can engage constant speed gear 50 and engage high speed shaft gearwheel 45 by constant speed gear 50 again, and the standard pitch diameter of constant speed gear 50 is less can reduce reduction gear packet size.
Scheme 4: directly control type: directly control type refers to the switch directly being controlled auxiliary valve 4 without train of reduction gears by track plate 12, in direct control type, internal gear 44 on train of reduction gears type middle orbit dish is removed, change level and smooth single-track 49 into, can be understood as a very large cam, single-track 49 can be that to protrude from track plate 12 also can be on track plate 12, remove a part form a level and smooth complete track, each track plate only processes a single-track 49, so side track plate 12 controls the one of in auxiliary intake valve 401 and auxiliary exhaust door 402, track plate is needed how far with a certain distance from circular cylinder body 3 one end distance (track plate in the valve shield control gear hereafter mentioned have plenty of away from circular cylinder body beneficial and necessary) when single-track 49 protrudes from track plate 12.The second bearing roller 40 in auxiliary valve 4 directly contacts with single-track 49.Wherein the control form of single-track 49 pairs of auxiliary valve 4 can be divided into two kinds: upper top formula and press-down type.Upper top formula refers to that bearing roller 40 rolls in the periphery of single-track 49, auxiliary valve is opened bearing roller 40 jack-up when orbit radius increases; Press-down type refers to bearing roller 40 side roll in single-track 49, when orbit radius reduces, the second bearing roller 40 is pressed down thus auxiliary valve is opened, these two kinds of auxiliary valve structures can be different, press-down type controls the center line angle of auxiliary valve control arm 39 and auxiliary valve principal part 38 in shape within 90 °, to ensure that the second bearing roller 40 rises with auxiliary valve 4 or declines simultaneously.For the auxiliary valve 4 of direct control type, the auxiliary valve control arm 39 of auxiliary valve 4 all should be processed in auxiliary valve 4 near track plate 12, and in the controlling method of press-down type, auxiliary valve control arm 39 processes the flowing being conducive to gas at side.
The compression ratio of the motor of this invention can be controlled by the change shape of piston 30 and the size of firing chamber 6, and firing chamber 6 is larger, and when lighting, gas volume is larger, and compression ratio is less; Piston 30 volume is less, and when lighting, in firing chamber 6, gas volume is larger, and compression ratio is less, and the motor of therefore this invention forms different compression ratios by the shaped volumes changing firing chamber 6 and piston 30, and various fuel thus can be used for work by combustion.The advantage that this motor also has other motors all not have: easily realize the repacking of engine start machine displacement variation, as long as the radius of its annular inner cylinder body 31 of rotor 2 changed changes, (certain piston 30 also changes, but piston peak and distance of center circle are from not changing) namely change cylinder 301 volume, the discharge capacity of motor will change, and certainly also needs to change supporting track plate 12 with it.
Motor of the present invention also achieves motor that other motors not easily realize easily and becomes motor when Displacement Technology and automobile temporarily stop and stopping work by combustion fast, need when starting, to make engine combustion acting start-stop technology fast, and engine start/stop technology is had new implication: be no longer to stall, but motor keep rotating but not consume fuel.When multiple cluster engine synthesis high power engine of the present invention arranged side by side needs some or multiple engine stop acting of the present invention to reduce oil consumption, as long as will all valve shields 1 of the motor of the present invention stopped be needed to move to peak position (relative to axle center) and make the projection 35(of valve shield 1 or the clutch shaft bearing roller 36 on it) de-orbit the control of coiling, make auxiliary valve 4 be in closed condition and depart from the control of cam 43 or track plate 12, although at this moment rotor 2 is rotated further, but do not have the process of pressurized gas, gas in cylinder 301 can along with the rotation of rotor 2, gaseous state is not changed, thus engine rotation and but do not need fuel, rotational resistance is minimum, same reason, when automobile needs interim stopping in order to saving fuel oil should close the fuel delivery to motor, all valve shields 1 moved to extreme higher position (relative to axle center) simultaneously and make the projection 35(of valve shield 1 or the clutch shaft bearing roller 36 on it) de-orbit the control of coiling, make auxiliary valve 4 be in closed condition and depart from the control of cam 43 or track plate 12, rotor 23 to be rotated further in annular cylinder body, do not cause the change of gaseous state in cylinder 301, thus rotational resistance is minimum, when motor needs work by combustion, by the projection 35(of all valve shields 1 or clutch shaft bearing roller 36 on it) introduce in the grooved tracks 267 of track plate 12, make track plate 12 continue to control valve shield 1 and complete normal work, and make auxiliary valve 4 be in by cam 43 or track plate 12 state of a control, because rotor 2 still has larger kinetic energy, all can the fresh wage of Fast Compression, light acting, motor is enable to realize fast starting.
Need to do certain improvement to aforementioned motor to realize said process, extreme higher position is rested on when engine rotation in order to make valve shield 1, a set of valve shield control gear need be installed additional, when this device can control engine rotation, whether valve shield moves up and down, this device can have kinds of schemes, as projection adds shifting axle bearing roller type, projection adds convex column type, and projection and valve shield divergence type.
Scheme 5: projection adds shifting axle bearing roller type: install on the projection 35 of described valve shield 1 and can be called the 3rd bearing roller 51 along projection axial movement of bearing roller, 3rd bearing roller 51 is substantially identical with clutch shaft bearing roller 36, but the 3rd bearing roller 51 can easily move along projection axis and process the cylinder ring 52 of a circle projection on the 3rd cylndrical surface of bearing roller 51 away from track plate 12 one end on projection 35, because protruding from the 3rd bearing roller 51 so this annulus 52 can enter in corresponding limiting groove track, and move along projection axis with limiting groove, this limiting groove is called the first limiting groove 53, projection 35 curtailment is now with in embedding people's grooved tracks 267,3rd bearing roller 51 moves into grooved tracks 267 to track plate 12, and move up and down with track 267, form grooved tracks 267 thus to the control of the 3rd bearing roller 51 and then the movement controlling valve shield 1.First limiting groove 53 is made up of 4 restriction tracks 54, be divided into two groups, one group two, article 4, restriction rail 54 is parallel, distance between two restriction tracks 54 of each group is slightly larger than the width of cylinder ring 52, thus can by a part for cylinder ring 52 restriction within it, two groups limit two the part increase restriction intensity of track 54 with limit cylinder ring 52 symmetry, first limiting groove 53 can limit moving axially of the cylinder ring 52 that the 3rd bearing roller 51 cylndrical surface processes, first limiting groove 53 can moving axially along projection 35, and then drive the 3rd bearing roller 51 to move axially, post pin 55 is connected with the first limiting groove 53, post pin 55 moves with the first limiting groove 53.When the dish 12 that needs valve shield 1 to de-orbit controls, as long as the first limiting groove 53 is moved to annular cylinder body 3, the 3rd bearing roller 51 is driven also to move to annular cylinder body 3, thus the 3rd bearing roller 51 dish 12 that de-orbits is controlled, post pin 55 simultaneously with the first limiting groove 53 movement inserts in the post holes 56 on valve shield 1, prevents valve shield 1 from moving down.First limiting groove 53 is fixed on annular cylinder body 3, by motor or engine-driving, it moves, when needs track plate 12 controls valve shield 1, first limiting groove 53 is subject to driving force and moves to track plate 12, drive in the grooved tracks 267 on the 3rd bearing roller 51 injection dish 12, the post pin 55 simultaneously inserting valve shield 1 is also extracted, and valve moves up and down, and these processes are all carried out when grooved tracks 267 radius at projection 35 place is maximum.
