2. the working procedure of motor

After with above unit construction, promptly accomplished the installation process of an interdigitated rotor engine.Gear train that its inside is contained constitute complete machine power train, lubricating system be set in power train, be provided with in boring on the motor body that spark plug constitutes complete machine igniting system, the cylinder that is separated out between by rotor and housing forms burning system, by on the gas port that pieces together of lower shell body constitute that ventilation is, the housing outer wall can be made cooling system; Cooling system can adopt air-cooled or water-cooled, constitute inertial system by the weight of rotor self; And when cylinder expansion, the inertial force between rotor can transmit mutually.When ato unit, need earlier the spark plug energising, make spark plug continue sparking or make the wire that contacts with gas be in high hot state, its heat during greater than the fuel burning-point again rotary output axis get final product ato unit.Igniting advantage of the present invention is that spark plug is not when gas pressure is the highest, to begin the energising igniting, but but constantly all at the red heat state of switching on and striking sparks or being in fire fuel.But, need not to worry gas by phenomenons such as backfires, because the distinctive motion mode of rotor makes gas at when compression contact sparking plug not, contact sparking plug again when gas reaches maximum pressure is so firing mode of the present invention is more special.In the selection of spark plug, also can use showing tremendous enthusiasm head with hot delay effect.Compression ratio of the present invention in addition is very high, reaches as high as 70: 1, so can use compression-ignited igniting, not restriction can be used ethanol when using fuel, and gasoline, diesel oil, hydrogen, any inflammable gas such as biogas are fit to popularize as power.

When ventilation; The present invention only needs that pore is set and gets final product on housing, need not to be provided with any ventilation valve mechanism, rotates because carry out trade-off among the present invention between double runner rotor; So natural aspiration and the mode of feeling elated and exultant are adopted in air inlet and exhaust, have increased the complete machine power-weight ratio.

Shown in figure 13, be rotor trade-off principle of rotation figure, what show among the figure is that the motor that double runner rotor constitutes rotor assembly is installed.The present invention is because of the gearing of A or B gear train, and when gas expanded, interlobate rotating manner was the trade-off rotating manner.Constituting the principle of carrying out this kind rotation between blade is: the power about gas acts on when expanding on the rotor blade equates; Promptly forward equates with two power of negative sense on two blades; Two double runner rotors should be done in the opposite direction with speed and rotate this moment; But because two rotors all connect transmission system, promptly two rotors are indirect being meshing with each other, again because in transmission system, be provided with elliptic gear; So the arm of force two rotor interphase interactions is different, and this arm of force changes.When output shaft is in 0 when spending, the arm of force between two rotors just equates, promptly the active force between two rotors equates that this moment, output shaft did not have moment of torsion output, rotates by inertia between rotor and advances.In the operation process of motor, the equal moment of the arm of force is moment between two rotors, adopts double runner rotor like motor; This instant value output shaft whenever carry out 180 when spending once, afterwards, arm of force difference is reverse between rotor; Make 1 week of rotor rotation, output shaft rotated for 2 weeks.When adopting four-lobe rotor like motor, the value that this moment equates is whenever carried out 90 degree once at output shaft, and the arm of force difference between rotor is reverse afterwards, makes rotor rotation during 1 week, and output shaft rotated for 4 weeks.Indicate at output shaft like Figure 13 and to turn to 180 when spending, the rotation process of double runner rotor by 0 degree.Turn to 30 when spending at output shaft, rotor 8 arm of forces begin the arm of force greater than rotor 9, thus its under the effect of expansive force, travel forward and drive rotor 9, when output shaft turns to 60 when spending; The arm of force that rotor 8 and rotor are 9 continues to increase, and turns to 90 when spending up to output shaft, the arm of force difference maximum that rotor 8 and rotor are 9; And no longer increase, when output shaft turns to 120 when spending, the arm of force difference that rotor 8 and rotor are 9 begins to reduce; This moment, rotor 8 continued to drive rotors 9 motions, when output shaft turns to 150 when spending, and the arm of force difference change that rotor 8 and rotor are 9 very little; But this moment, rotor 8 arm of forces were still greater than the arm of force of rotor 9, and promptly output shaft still has moment output, when output shaft turns to 180 when spending; The arm of force of rotor 8 equates again that with the arm of force of rotor 9 this moment, arm of force difference equaled 0, the output of output shaft non-moment.Above process has promptly been accomplished the time of a stroke, and 4 cylinders in the rotor chamber have just been accomplished expansion, exhaust, air inlet, compression process.Because the position of spark plug is not herein, but a little near relief opening one end, so this moment pressurized gas do not light.Continue to rotate forward like output shaft, then the arm of force of rotor 9 begins the arm of force greater than rotor 8.Gas after compression this moment contacts with spark plug, and gas is lighted and expanded, and rotor 9 begins to drive rotor 8 and travels forward, and realizes the differentiation of an arm of force difference new round, and realizes stroke next time, makes the present invention realize continuous running.

Like the schematic diagram of Figure 14,15 for taking a breath between cylinder of the present invention and doing work; This figure shows is the ventilation principle of motor when double runner rotor is installed, and when motor was equipped with double runner rotor, output shaft rotated 720 degree; Rotor rotation 360 degree are promptly accomplished once acting circulation.Suppose output shaft in 0 degree position, the arm of force difference between rotor A and rotor B is 0 at this moment, i.e. motor non-moment output, and they just are in alternate position.On rotor A, be provided with rotor blade A1 and rotor blade A2, rotor blade B1 and rotor blade B2 are set on rotor B.Shown in figure 15ly turn to 180 when spending when output shaft, motor is accomplished a stroke procedure, i.e. A1, and B1 realizes aspirating stroke; B1, A2 realizes compression stroke; A2, B2 realizes expansion stroke; B2, A1 realizes exhaust stroke.When output shaft turns to 360 when spending, A1, B1 realizes compression stroke; B1, A2 realizes expansion stroke; A2, B2 realizes exhaust stroke; B2, A1 realizes aspirating stroke.When output shaft turns to 540 when spending, A1, B1 realizes expansion stroke; B1, A2 realizes exhaust stroke; A2, B2 realizes aspirating stroke; B2, A1 realizes compression stroke.When output shaft turns to 720 when spending, A1, B1 realizes exhaust stroke; B1, A2 realizes aspirating stroke; A2, B2 realizes compression stroke; B2, A1 realizes expansion stroke.More than be an acting circulation of rotor, work on, then carry out with cocycle once more between rotor like motor.

Shown in figure 16ly do a circulation time for motor, the torque curve figure of this motor and available engine.Curve 1 is torque curve figure of the present invention among the figure, and as can be seen from the figure, torque curve of the present invention is non-cosine curve; Because used elliptic gear among the present invention as transmission system, thus the arm of force between two double runner rotors change, and when the output shaft uniform rotation; The variance ratio of arm of force difference is very little between two double runner rotors; Arm of force difference is when the highest, and the speed of variation just begins to slow down, so the change in torque speed of this motor is straight line.When motor turned round continuously, the torque curve of the present invention's output was a continuous skew lines that has knuckle, when moment of torsion arrives zero, begin turnover, and curvature was constant.Curve 2 is the torque curve of three-apexed rotor formula motor among the figure, and curve 3 is torque curves of reciprocating engine, and they all are cosine curves.Torque curve of the present invention is the straight line that has knuckle, so the present invention has higher energy conversion efficiency, is more suitable for being applied to energy-conservation and high-power type equipment and uses.

Described above is the principle of the present invention as motor; Output shaft of the present invention rotates and the rotation of rotor can reverse mutually; When the spark plug in the rotor chamber of the present invention also being changed into a cover gas port; Be that each rotor chamber of complete machine that double runner rotor constitutes is provided with two cover gas ports, each rotor chamber of complete machine that four-lobe rotor constitutes is provided with the quadruplet gas port, and then the present invention becomes a pump or the moving equipment of gas-liquid.
