Description
Technical field
The present invention relates to a kind of internal-combustion engine, specifically, relate to the internal-combustion engine that a kind of piston rotates, be applicable to the large combustion machine that on helicopter or submarine, uses.
Background technique
In field of internal combustion engine, people are to realizing that the internal-combustion engine that piston rotates is persistent, and purpose is to raise the efficiency, and reduces noise, reduces and pollutes, and improves technical orders such as output power.In this, Axela Inc. of Japan, U.S. Jamie Lee Curtis Lai Te company, John Deere ﹠ Co. etc. successively researches and develops success and gets achievement preferably, but the intrinsic shortcoming that exists because of Wang Ge Er scheme itself causes the oil consumption height, and pollution heavily waits shortcoming to improve at all.
Shortcomings such as traditional combustion engine is because of complex structure, and weight is big, and output power is low withdraw from this arena of history of aviation field already, and people are that feelings have only inner feelings for circular movement, up to the present do not find desirable scheme unfortunately as yet.
Summary of the invention
The present invention is a kind of connecting rod that do not have, and the new scheme of the motion that rotation of piston do and straight line combine specifically has following content:
One, designed a kind of cylinder body outer ring that surrounds as the bent limit of 5 distortion that constituted circumference in the accompanying drawing 1.
Two, a kind of and spoke is fixed together, and the heat insulation ring that rotates with spoke is as among Fig. 12.
Three and the spoke seal ring that is fixed together and rotates, 23 represented as among 3 among Fig. 1 and Fig. 3.
Four and Fig. 1 in 5 parallel work are cold goes up 26 among steamboat (as steamboat among Fig. 6 28) orbit that rotates such as 4 and Fig. 4 among Fig. 1.
Five, by the periphery that is out of shape, circular seal ring, the bent limit " triangle cylinder body " that cylinder body 24 in the accompanying drawing 4 and the cylinder cap 30 among Fig. 7 are constituted is shown in 1 among Fig. 1.
Six firing chambers that are connected and can swing with the body cover, 10 among shape such as Fig. 2 also has inlet hole 9 and exhaust port 8 on the firing chamber.
Seven, the present invention is that the front and back that a kind of piston moves are worked the two-stroke internal-combustion engine of the mechanism of need not taking a breath simultaneously.
The present invention should have following beneficial effect:
1, efficient height: the present invention reduces energy loss owing to discarded crank disk shape composite internal combustion engine structure and the big valve mechanism of energy consumption.The recycling of waste gas waste significantly reduces in addition, will significantly raise the efficiency the minimizing fuel consumption like this.
2, noise is low: the present invention does not have bent axle, and noise will reduce significantly.
3, same displacement power significantly improves: internal-combustion engine of the present invention is because be two strokes, and the piston sequential working, and power will significantly improve.With the four-cylinder is example, and traditional combustion engine is because be four-stroke, and main shaft changes 720 ° of pistons 4 works done, and main shaft of the present invention changes 360 ° of pistons and merit 8 times, exceeds 4 of traditional combustion engine.Can strengthen the body diameter and increase the piston logarithm and then export number of times and become quadratic growth if improve output power by following formula:: W=2 * N
2
W: 360 ° of piston works done of main shaft number of times
N: the number of pistons of work done
The piston sum is increased to 12 promptly 6 work doing pistons is then for increasing power like this:
W＝2×N
2
＝2×6
2
=72 times
It is quite huge that piston promotes.
4, stroke is big: reception room internal combustion engine diameter and stroke ratio are approximately 1: 1 and internal-combustion engine of the present invention is approximately 3 to 4, and this point traditional combustion engine can't realize because connecting rod is arranged.Because stroke is big, piston and high temperature and high pressure gas long action time are so can raise the efficiency.Again because stroke has the sufficient reaction time for greatly waste gas and additive, to improve the pollution situation of tail gas.
5, be applicable to that promptly igniting is applicable to compression ignite again: internal-combustion engine of the present invention is provided with the moving firing chamber of can slightly stating the fact between two adjacent cylinder bodies, we can be by changing the firing chamber size and two cylinders between the size of distance reach the size that changes advance angle, light and compression ignite between select.Internal-combustion engine ignition of the present invention in addition is to carry out under independent sealed condition, has significantly reduced traditional combustion engine owing to the necessary piston that advance angle caused and the reverse energy loss that causes that contacts of flame.
6, improve output power easily: for adapting to the needs of bulk loads such as train, steamer etc., the present invention can increase the number of pistons of cylinder body with the method that strengthens the body diameter, as 12,18 even more, just can significantly improve output power, if adopt the parallel connection combination of many groups, can be improving power output becoming a light and easy undertaking.
7, research and development simple in structure are easy: owing to adopt disc-shaped structure, make structure very simple, if disregard subsidiary engine and standard piece, every cylinder has only several parts, and machining does not simply have specific (special) requirements yet, and R﹠D costs reduce significantly.
8, Safety performance height: the present invention is because number of spare parts is few, and rate of fault is low to be conspicuous, and the present invention can introduce aerial the use to this oil because of being applicable to the compression ignite of diesel oil in addition, thereby improves the Security of propeller driven airplane flight.
9, application area is big: internal combustion (IC) engine airframe of the present invention is circular, increasing the cylinder number as enlarged can make power increase and the decline of torque increasing rotating speed, add suitable design, can make main shaft directly promote rotor, can remove the big deceleration system of the big weight of noise from and become possibility.Make it like this to fly to use the thing become possibility going straight up to.Very little in addition noise and the output of huge power if use on submarine, make the other side's scouting more difficult undoubtedly.

Embodiment
Requirement according to Patent Law, invention should have novelty and practicability, and the present invention changes that bent axle is arranged is that no bent axle novelty is a nature, and practicability then should be based upon on the practical feasibility basis, practicability and feasibility are inseparable in other words, and it is the soul of an invention.Be its feasibility of proof for the present invention.By the analysis to traditional combustion engine and " triangle " motor running principle and pluses and minuses thereof, we summarize four laws or are called four axioms.
1, gas conversion law.Any reciprocating engine will reliably move efficiently, must realize that combustible gas changes to the piston method of operation before the piston traffic direction timely backward.
2, Transmitted chains law.Any reciprocating engine begins until the front end of load from piston, and any major-minor mechanism constitutes a Transmitted chains, comprise piston just what one to encircle the influence that can the resistance that be caused normally move piston be identical.
3, sealing law of comparison: when weighing sealing effect, the sealing configuration that is made of the broken line of mutual embedding is than the good sealing effect between the plane.
4, pressure law of comparison: the suffered side pressure of moving object and more much smaller to the influence of motion than the positive pressure opposite with moving direction.Concrete analysis below:
If admit the accuracy of above-mentioned running principle, just can draw following conclusion.
1, according to gas conversion law, the present invention be according to piston by seal area the time and combustible gas disengage to the gas conversion creates conditions, and this law has been realized by swing in the firing chamber that can swing.What deserves to be mentioned is that why not very successful triangle piston starts is exactly not defer to this rule.To find out as accompanying drawing 10 and not indicate sense of rotation, can who confirm turning to of it?
2, the most difficult piston normal possibility moved in approved by people of the present invention by " triangle " cylinder body that circumference and circular seal ring constituted of distortion.This query can be readily solved if this point can be admitted the Transmitted chains law.More much smaller because of the resistance of the suffered cylinder body falling ramp of piston than the resistance of traditional combustion engine valve open and close system, can not impact naturally normal operation of the present invention.
3, sealing of the present invention is to lean in the cell body of seal ring embedding cylinder body and cylinder cap to realize, and the triangle motor relies on plane contact fully, the just easier realization sealing of the present invention certainly.
4, can swing burning to the present invention, institute is influenced during swing.(as accompanying drawing 9) and traditional combustion engine are contrasted at piston compression stroke latter stage (being ignition advance angle latter stage) piston stressing conditions (attached power 8) just can find out that the traditional combustion engine piston still can fine work under the effect of the prevention of reverse positive pressure 4 and side pressure 1, does not have reverse positive pressure to have only the swing of the firing chamber of side pressure influence to be out of question certainly so.
Comprehensive above-mentioned argument, main feature of the present invention: the curvilinear triangle cylinder body, circular embedded seal ring, the burning of swinging type can both normally move, and the present invention just has great feasibility.The existing rotary engine of the auxiliary problem (AP) of others all solves, and we just use for reference.
The rationality of second configuration aspects.For the rationality of structure, can be equally and the triangle motor of Japanese Axela Inc. exploitation of rotary combustion engine do contrast in detail.
One, the contrast of rotation principle.
It is the basic demand that main shaft can rotate that main shaft is had the effect of moment, and the triangle piston of triangle engine interior is a kind of eccentric stiffener to main shaft, and it is the critical component that produces torque, and still less from the structure arm of force should be its weakness.
The product of the piston of crankless internal-combustion engines along the power that fires of the suffered mixed gas of the periphery piston of body and piston to the distance of main shaft is to produce rotating moment.Characteristics moment of the present invention obviously increases greatly because of the arm of force, and adds and strengthen with the body increasing diameter, though therefore output power can not increase.But he is applicable to the helicopter application of the big torque of the slow-speed of revolution.
Two, piston orbit contrast
The piston orbit differs widely though triangle motor and crankless internal-combustion engines all are revolving, though it is less all can be referred to as the track deformation of triangle motor under " distortion circle " contrast, and the track deformation of Crankless ic is bigger, from seeing the piston orbit slyness of crankless internal-combustion engines piston orbit in appearance not as the triangle motor, as if it is big that the piston running resistance is wanted, and this takes advantage from resistance triangle motor.
The piston running orbit of triangle motor is an epitrochoid, and it is had regulations to abide by, and crankless internal-combustion engines is then different fully, and its piston orbit is artificial the achievements, and randomness is bigger, and its shape and structure is key of success of the present invention place.Labor is as follows, significantly reduce if at first analyze the extending amount of piston, then to approach circle should be feasible to track certainly, but discharge capacity significantly reduces thereupon, then practicability reduces, and finds a rational critical value can accomplish fully thereby employing progressively strengthens extending amount.Secondly analyze the piston orbit it three kinds of modes first are arranged is that the difference of upper deformation radius remedies with camber of spring fully.The secondth, adopt the upward less track of the big lower railway distortion of facial disfigurement for overcoming unnecessary running resistance.The difference of radius aspect remedies than small deformation with spring, for the box-like spring of extending amount available set that reduces spring is solved.We believe sure by experiment rational service data and the scheme of finding in a word, though can not affirm still that by above-mentioned analysis contrast crankless internal-combustion engines takes advantage, and says into draw and is fine.
Three, piston stressing conditions contrast.
The triangle engine piston is to be distributed in the positive and negative two pairs of moments about equally of promptly producing simultaneously of piston both sides in suffered power of the initial stage of flame combustion for the vertical shaft center, and the overall process that is present in piston operation that differs in size of this positive negative moment, though under effect of inertia, can run well.
But a certain amount of power loss is that inevitably crankless internal-combustion engines is then completely different, and the suffered combustion force of its piston is on all four in each moment and piston motion direction, does not have the moment loss.The present invention has overwhelming superiority in this contrast.As long as changing as for the issuable component that piston is descended above the piston, top shape can overcome.
Four, cylinder body contrast.
The cylinder body of triangle motor is an oblate cylinder body that is made of cycloid, each group mechanism is that the shared cylinder body of three cylinders is that triangle piston rotation reaches and a week makes three times merit in same cylinder body, for guaranteeing to run well, size to cylinder body, machining accuracy degree of finish requires all very high, crankless internal-combustion engines is then different, its cylinder body is curve " triangle ", and the position is provided with at the body surrounding edge, and quantity is even number, cut with number of pistons and equate, each cylinder independently exists, and works alone, and different pistons pass through in cylinder body, finish air-breathing exhaust respectively, four requisite strokes of work done compression.Total cylinder number can increase with the increasing of body diameter, so but on shape of block, there is not comparative, quantitatively then occupy clear superiority.
Five, firing chamber contrast
The firing chamber of triangle motor is the part of cylinder body and piston, the shared firing chamber of three cylinders, sequential working, be subjected to the shape volume of the restriction firing chamber of cycloid can not do significantly to change, on limited data, it is grow flat arc, cross section is a rectangle, its shortcoming is that shape is bad, compressed combustible gas is not concentrated, whole energy of combustible gas are given full play in the quick propagation of unfavorable flame, and I think that this may be that the triangle motor is failed in decades in one of reason of the wide range applications that expands.
The firing chamber of crankless internal-combustion engines is independent of outside the cylinder body, independently is present between two cylinders, and one in every cylinder works alone separately, but artificially design of the burning of shape based on fuel, and change also is very easy to, can the small size swing in front and back.Can certainly make fixed as required.It can fully adapt to the needs that improve combustion efficiency.With small size swing be example, swing can receive the air of compression and combustible gas is opened vent hole simultaneously and closed exhaust port backward.Swing then can be discharged the high temperature and high pressure gas promotion piston work done of burning forward.Open the vent closure suction port simultaneously, contrast above-mentioned argument, the combustion chamber scheme of crankless internal-combustion engines should occupy greater advantage.
Six, piston contrast
The piston of triangle motor is so name Si Yi is that a kind of triangle both sides are the assembly that works alone on plane.Rely on inner eccentricity gear to be connected with main shaft, the plane of both sides also is used for covering and close and open suction, exhaust port with assurance motor proper functioning regularly, and three faces are finished the various functions of a piston respectively separately, plays with one and pushes up three effect.The piston of crankless internal-combustion engines is rectangle haply, both sides also are that plane quantity is even number, and increase with the increase of body diameter, their odd number even number function is inequality, finishes respectively, work done and compression, and air-breathing and degassing function, piston links to each other with main shaft by the groove on the spoke, and this respectively has characteristics, comparative is little, can think deuce.
Seven, working procedure contrast.
The triangle motor is similar to four stroke engine, and finishing of piston order is air-breathing, compression, work done, exhaust, four functions, and the utilization ratio of piston is lower.
Crankless internal-combustion engines is then different, and it is a kind of internal-combustion engine that is similar to two strokes, and adjacent two-piston is finished work done compression and four kinds of functions of air-breathing exhaust respectively at one time.But it is different with traditional combustion engine, and it does not have the air-vent that the sort of loss is big, mechanism is complicated.Piston stroke of the present invention in addition can artificially be set, and is fit to very much the needs of raising the efficiency.The working procedure that can conclude crankless internal-combustion engines is better than the triangle motor certainly.
Eight, exhaust mode contrast.
One of advantage of triangle motor be it loss is not big, the inlet and exhaust valve of mechanism's complexity replaces regularly to cover with piston and closes and open port and finish inlet and outlet work.The same inlet and outlet door of also not establishing of crankless internal-combustion engines with the triangle motor, has only port, different is that the present invention covers with the swing of firing chamber to close and open the inlet and outlet hole, carries out degassing function this need not contrast so finish, and it is fair saying into draw.
Nine, compression ratio contrast
Compression ratio is one of important indicator of motor.The triangle motor is subjected to structural restriction, can't liken to significantly compression to change, and gives full play to the benefit of mixed gas, Here it is one of the main cylinder of triangle motor owes not as can be known yet.The compression ratio of crankless internal-combustion engines can be artificial significantly align easily, fully adapt to the needs of burning, this makes the present invention not only be applicable to petrol engine, the method for also available change compression ratio, use diesel oil to be used as power, be better than the triangle motor by contrast certainly.
Ten, rotating speed contrast.
The triangle engine design is once determine, the rotating speed of piston and main shaft be exactly definite value, data record spindle speed is three times of piston rotating speed, should belong to high rotating speed internal-combustion engine.
Crankless internal-combustion engines, piston is made circular movement along periphery, spindle speed is lower, and with the increasing of body diameter, though power increases substantially, rotating speed is really lower, our gross estimates: if the body diameter reach one meter some more, the rotating speed of main shaft has only hundreds of commentaries on classics, it should belong to wool(l)y-type engine, both sides respectively have short length under the contrast, can tie.
11, work done number of times contrast.
360 ° of main axis rotation, all the work done number of times of piston should be the important techniques index, the triangle motor changes 360 ° of piston works done once, change that can not be artificial because of the special main shaft of structure.
Crankless internal-combustion engines is completely different, and its main shaft changes the twice that 360 ° of work done number of times are work doing pistons numbers square.See that from this point the advantage of crankless internal-combustion engines is fairly obvious.
12, ignition advance angle contrast.
The choose reasonable of advance angle, it is one of modern motor important means of raising the efficiency, we still do not know the levelling scope and the amplitude of triangle advance angle of engine ignition at present, we estimate because the piston structure of triangle motor is special, probably should not select the advance angle that is more suitable for, crankless internal-combustion engines then can be selected in the larger context flexibly, because there is a seal area can supply to utilize between main two cylinder bodies.This crankless internal-combustion engines also is better than the triangle motor of Japan.
13, output power contrast.
Dragging all kinds of equipment that vary in size with motor, is common purpose, and the triangle motor is subjected to the restriction of mechanical structure, and output power can not be too big, present also on hundreds of kilowatts level from data.Crankless internal-combustion engines can increase the body diameter and many groups method in parallel improves output power, and making it to reach thousands of kilowatts even tens thousand of kilowatts is not difficult matter, and this present invention definitely is dominant.
14, sealing situation contrast.
Excellent sealing is the necessary condition that guarantees the motor proper functioning, so being the present invention, the quality of this contrast has or not the key point of feasibility, triangle engine cylinder-body potted line length overall is approximately 6-7 times of three limit length overalls of triangle piston, and the face of sealing is to rotate mutually and slip between the plane.Can guarantee the just resident work of motor from this encapsulating method of data.
The encapsulating method of crankless internal-combustion engines is to embed by the seal ring side grooves to realize sealing in the corresponding cell body in body both sides.Can add flexible Stamping Steel Ribbon in the appropriate location of cell body in case of necessity, this point triangle motor is difficult for realizing that as for the length of potted line, they are very nearly the same.We are assigned to whole potted lines on each cylinder in rough calculation, also big to identical, and on method, crankless internal-combustion engines still occupies certain advantage.
15, cooling means contrast.
The triangle motor is the same with crankless internal-combustion engines, and its profile all is an oblateness roughly.As long as open the passage of a little water holes as cooling water in the cylindrical and the both sides of body, just can reach cooling purpose, they should be effectively same for this point.
16, lubricating system contrast.
Lubricating system for the triangle motor is not understood fully from limited data, but all normally moves with large quantities of automobiles of this motor assembling.Illustrate that lubrication problem solves.Be revolving crankless internal-combustion engines so equally, in that solve on the lubrication problem also can difficulty, in this contrast, think and wait until mutually and be fine.
17, efficient just contrasts.
My data at hand of fuel consumption efficiency problem for the triangle motor has following description ... progressively overcome the big cylinder point of its oil consumption and discharge amount of exhaust gas ...This is with regard among obviously big, the inefficient shortcoming of oil consumption is overcoming.The characteristics of its structure of crankless internal-combustion engines that we invent itself, such as firing chamber independently, bigger expansion space stroke, the compound utilization of waste gas wait until it all is the necessary reliable condition of raising the efficiency, and believe firmly that the Crankless ic chance takes advantage so this contrasts us.
18, noise output contrast.
The running noise of rotary engine can be sure well below the traditional type motor, owing to structural reason, the piston orbit of crankless internal-combustion engines is more slick and sly not as the cycloid track of triangle motor, and noise output in place is also big than Japanese Axela Inc. triangle motor also to be nature.
19, blowdown flow rate contrast.
Society requires more and more high to the pollution of tail gas at present, the quality of the situation of tail gas and the burning of mixed gas has direct relation, the combustion-chamber shape of triangle motor is unsatisfactory, and artificial improvement is also very difficult, it also is the act that is difficult for that nature must improve the tail gas situation, crankless internal-combustion engines, its firing chamber is independent of outside the cylinder body, comes more easily than triangle motor naturally so improve tail gas pollution.
20, application area contrast.
Rotary engine, because it is simple in structure, the advantage that noise is very low, it should have good application prospects, personage in internal-combustion engine circle also once placed on very big expectation, and the low-power of triangle motor, the reality that high pollution etc. are merciless, but limited its application area, once a spot of application had been arranged at automobile.
Crankless internal-combustion engines, though be a scheme also, from its special structure, we estimate that it will have high-power, low noise.The advantage that low emission, the slow-speed of revolution etc. are powerful, make it at aspects such as aviation, navigation, industrial traffics very big development space will be arranged all in the future, for example: the body enlarged diameter to 1.4 of crankless internal-combustion engines meter, cylinder body increases to 12-14, discharge capacity will have tens of liters, spindle speed is on 300 right sides of turning left, and need not slow down just to drive the rotor of helicopter, and it has special future in this scope to these characteristics with the right to use.Its low noise and high-powerly undoubtedly good prospect will be arranged on submarine in addition, comprehensive above-mentioned we think that the present invention also takes advantage on application area.
In order to analyse us more clearly every contrast is listed as follows:
Crankless internal-combustion engines predicted performance and triangle motor contrast table
From statistics, find out that crankless internal-combustion engines accounts for and have great advantage that wherein account for the superior and be 13 and account for 65%, the deuce project is 6 and accounts for 30% that the person of being in a disadvantageous position has only one to account for 5%, for the enforcement of complete machine, does following statement in conjunction with the accompanying drawings:
In accompanying drawing 2, we suppose that internal-combustion engine of the present invention runs well, it is respectively at air-breathing exhaust position that piston is positioned the position, and work done, compression position, each piston and seal ring, thermal-protective coating is motion clockwise together, even number piston 16 under the high temperature and high pressure gas of piston combustion bowl 19 and air outlet hole 6 promotes clockwise motion simultaneously before the piston on a stroke compress by odd number piston 15 inhaled airs, also 7 be pressed into next firing chamber from air inlet, and to spray in good time combustible gas (with invention irrelevant be not marked as in the drawings next stroke work doing pistons by the envelope district after, work done in next cylinder body, get ready, also will compress simultaneously certainly previous piston inhaled air.The work that goes round and begins again thus.
