Be principle of rotation figure of the present invention as shown in figure 10, identified three spaces that constitute between elliptic rotor and delthyrial cavity member among the figure, be i.e. A, B, three spaces of C.Among the figure by 7 little figure prescribed space A volume big from changing to for a short time, change to little whole process again.When the rotating ratio between elliptic rotor and delthyrial cavity member is 3: 2.A is an initial position among the figure, and when this motor arrived the D position by the A position, elliptic rotor rotated 270 degree, and the delthyrial cavity member rotates 180 degree, and this time space A becomes maximum by minimum.When this motor by the D rotated position during to the G position, elliptic rotor turns to 540 degree, the delthyrial cavity member turns to 360 degree.This time space A becomes minimum again.When rotor is rotated further, then the volume of cylinder A continues to do cyclically-varying.
Be the rotating speed schedule of proportion of elliptic rotor of the present invention and delthyrial cavity member as shown in figure 11, and circulate as a reference by four of a cylinder.As can be seen from the table, the rotation ratio between rotor of the present invention and cylinder is 3: 2, promptly turns to 1080 when spending when elliptic rotor, and the delthyrial cavity member turns to 720 degree.
Be expressed as the present invention's principle of doing work as Figure 12 and Figure 13,12 can intuitively see the four-stroke running principle of motor at one of them cylinder of when work among the figure, be in 0 degree during the position when elliptic rotor among the figure, cylinder A is in a circuit incipient stage, when elliptic rotor turns to 270 when spending, it is maximum that the volume of cylinder A reaches, and promptly finished breathing process.When elliptic rotor turns to 540 when spending, it is minimum that the volume of cylinder A reaches once more, promptly finished compression process.When elliptic rotor turns to 810 when spending, the volume of cylinder A changes to maximum once more, has promptly finished the acting process.When elliptic rotor turns to 1080 when spending, cylinder A volume changes to minimum, has promptly finished exhaust process.More than be the four-stroke principle of cylinder A when engine operation.
Because be separated out three spaces between rotor of the present invention and delthyrial cavity member, i.e. three cylinders.Figure 13 indicates intuitively when elliptic rotor rotates, the working procedure of three cylinders.When elliptic rotor turns to 270 when spending by 0 degree, cylinder A carries out intake process.When elliptic rotor turns to 540 when spending by 270 degree, cylinder A carries out compression process.When elliptic rotor turns to 810 when spending by 540 degree, cylinder A carries out the acting process.When elliptic rotor turns to 1080 when spending by 810 degree, cylinder A carries out exhaust process; When elliptic rotor turns to 90 when spending by 0 degree, cylinder B carries out inflation process.When elliptic rotor turns to 360 when spending by 90 degree, cylinder B carries out exhaust process.When elliptic rotor turns to 630 when spending by 360 degree, cylinder B carries out intake process.When elliptic rotor turns to 900 when spending by 630 degree, cylinder B carries out compression process.When elliptic rotor turns to 1080 when spending by 900 degree, cylinder B carries out inflation process; When elliptic rotor turns to 180 when spending by 0 degree, cylinder C carries out compression process.When elliptic rotor turns to 450 when spending by 180 degree, cylinder C carries out inflation process.When elliptic rotor turns to 720 when spending by 450 degree, cylinder C carries out intake process.When elliptic rotor turns to 990 when spending by 720 degree, cylinder C carries out intake process.When elliptic rotor turns to 1080 when spending by 990 degree, cylinder C carries out compression process.
The working procedure that can be analyzed cylinder by above process continues the next stroke of 270 beginnings for each cylinder.Output shaft whenever carries out 90 degree, and some spaces begin next stroke in three spaces.Moving 360 degree of elliptic rotor revolution, gas expands once, and the path that gas expands is 270 degree.It is high a lot of that the more existing motor of the combustion efficiency of this sample motor is wanted, moving 360 degree of existing Reciprocating engine bent axle revolution, and gas does work once, and the acting path is 180 degree.
Explained above is that the present invention uses single rotor to constitute the various members of motor, when changing the present invention into double rotor, needs to revise and increase new parts.The member explanation that is to use double rotor to constitute motor described below.
2. the various parts of birotary engine
As shown in figure 14, be the parts that increase newly of birotary engine, this member is middle casing (29), and its effect is with up and down two elliptic rotors are spaced apart, and combustible gas is transported to up and down in two-part cylinder.On this middle casing member, be provided with annular air channel (14) equally, and upper and lower surfaces have, and at the annular air channel home position, are provided with the output shaft hole (13) that is used for output shaft and passes, circumferential surface side at this member also is provided with suction port (15), is used to import inflammable gas.
As shown in figure 15, rotor component for birotary engine, from figure, can clearly recognize, when using the double rotor member to constitute motor, the present invention will be decomposed into elliptic rotor (1) elliptic rotor (1A) and following elliptic rotor (1B), and this elliptic rotor is not connected with output shaft (1C).On each elliptic rotor, all be provided with rotor of output shaft axle hole (27), in this hole, also be provided with keyway, on output shaft (1C), be provided with keyway equally, opposed 180 degree of keyway.When the double rotor member is installed, earlier key (28) is installed on the output shaft (1C), output shaft is inserted in the epitrochanterian rotor of output shaft axle hole (27) again.This moment, two rotors (1A) were (1B) fixing with output shaft (1C) up and down, can not rotate around output shaft.When engine operation, expanding gas promotes elliptic rotor and rotates, and rotates thereby drive output shaft.
It should be noted that, when using double rotor, two air flues of upper rotor part and two air flues of lower rotor part are to be that the axle point carries out opposed with the output shaft, like this when engine running, last lower rotor part can alternately do work, the exportable continuous dynamic curve of output shaft, and make this curve near straight line, even moment of torsion is near straight line.
When the needs combustible gas is imported by middle casing, when waste gas is exported in motor two sides up and down afterwards, two-spool duct position of the present invention is different with the single rotor duct position, promptly end face is provided with intake duct on the bottom surface of upper rotor part and lower rotor part, the bottom surface of end face and lower rotor part is provided with air outlet flue on upper rotor part, and make two rotors when rotation 180 is spent, and two epitrochanterian intake duct directions are identical up and down, and the air outlet flue direction of two rotors is identical up and down.
As shown in figure 16, be the longitudinal section of birotary engine, as can be seen from the figure the center portion of motor complete machine is a rotor assembly, is made up of output shaft (1C), the upper rotor part (1A), the lower rotor part (1B) that are enclosed within on the output shaft.Outside last lower rotor part, be with two delthyrial cavity members respectively, promptly go up delthyrial cavity member (2A), following delthyrial cavity member (2B).Also be provided with the stator assembly of motor in their outsides, by upper shell (3), casing top half housing (4A), middle casing (29), following cylinder casing (4B), the common formation of lower shell body (5).All be provided with bolt hole (7) in each shell rim, be used for housing bolt (6) and pass fixedly complete machine.On last lower shell body, be provided with spark plug (8) equally, be used for lighting the inflammable gas after the compression.
Be the air exchange system figure of birotary engine as shown in figure 17, observe the gas recycle process that this figure can recognize birotary engine.Inflammable gas is entered by the suction port on the middle casing (15) among the figure, passes annular air channel and enters into up and down in the cylinder, and along with the rotation of rotor, gas compresses, do work in cylinder, afterwards by air outlet flue (16) discharge of last lower shell body.Notice that upward the parts of lower shell body are constant at this moment, but function is different from the use one-spool engine, promptly its gas port all is a relief opening.
Torque curve figure when rotating a week for elliptic rotor among the present invention as shown in figure 18, curve 1 is the torque curve figure of one-spool engine among the figure, the torque curve of single rotor is not the cosine form as can be seen, but a kind of shape of similar parabolic, and curve is in rotor rotation 360 degree, the moment of torsion endurance is 270 degree, and therefore the more existing Reciprocating engine of engine combustion efficiency of the present invention wants high.Curve 2 is the birotary engine torque curve, the torque curve of birotary engine does not have 0 point as can be seen, promptly when cylinder does work, the end of not doing work of a cylinder, another cylinder begins acting, produces the acting superposition phenomenon, and the torque curve that makes this motor is near straight line, and continue the moment of torsion that provides bigger, energy conversion efficiency is increased significantly than available engine.
