Embodiment

Fig. 1-6 shows a kind of structure and fundamental diagram of oval sliding vane type engine.Among the figure, oval sliding vane type engine mainly comprises a cylinder block 1, cylindrical rotor 2, cam 3, intake duct 1a, air outlet flue 1b, fuel nozzle 6 and spark plug 7.Cylinder block 1 adopts an elliptical cylinder-shape cylinder 1c, cam 3 is fixedly mounted in the cam chamber of elliptical cylinder-shape cylinder 1c two ends end cap, the long axis direction of cam 3 is consistent with the long axis direction of elliptical cylinder-shape cylinder 1c, and a cylindrical rotor 2 that is installed in the cylinder block 1 is tangent with the corresponding position of elliptical cylinder-shape cylinder 1c minor axis.On cylindrical rotor 2, be provided with the first passage 2c and the second channel 2d that becomes knuckle of one first chute 2a, the second chute 2b, one-tenth knuckle, angle between the first chute 2a and the second chute 2b is 60 degree, in this 60 degree angular range, axial direction along cylindrical rotor 2 is provided with two first passage 2c, in 300 degree angular range, two second channel 2d are set along the axial direction of cylindrical rotor 2.On the sense of rotation of cylindrical rotor 2, a main slide plate 4 is installed in first chute, main slide plate 4 is provided with a main sliding cap 4a and two main roller 4b, and a secondary slide plate 5 is installed in second chute, and secondary slide plate 5 is provided with a secondary sliding cap 5a and two secondary roller 5b.The width of main roller 4b is two times of secondary roller 5b width; Corresponding, cam 3 is to spray and two times of compression process one end thickness corresponding to fuel corresponding to the thickness of burning work done process one end.Center at elliptical cylinder-shape cylinder 1c, by counterclockwise, intake duct 1a at first is set on the cylinder block between ellipse short shaft and the major axis 1, on transverse corresponding cylinder body 1, fuel nozzle 6 is set, on ellipse short shaft relative and the cylinder block 1 between the major axis, spark plug 7 is set again, at last on the cylinder block 1 of the opposite side of intake duct 1a adjacent ellipses minor axis, air outlet flue 1b is set with intake duct 1a.When cylindrical rotor 2 rotations, the sliding cap of slide plate end slides on the inwall of elliptical cylinder-shape cylinder 1c, main roller 4b and secondary roller 5b roll on cam 3, finish the work cycle of intake process, fuel supply, compression process, igniting, burning work done process and the exhaust scavenging process of oval sliding vane type engine, power is by the output of the output shaft on the cylindrical rotor 2.

The working principle of this motor is as follows:

A) intake process: as shown in Figure 1, main slide plate 4 is from 270 degree, and rotation in the counterclockwise direction begins air inlet through suction port 1a, slips over suction port 1a up to secondary slide plate 5 and is over, and intake process is finished.

B) fuel supply: as shown in Figure 2, fuel nozzle 6 begins to supply with gasoline or inflammable gas, and cylindrical rotor 2 is rotated further.

C) compression process: as shown in Figure 3, it is not obvious that the compression stroke of this motor embodies, volume compression 2-4 doubly, so do not need to consume too big energy yet, when main slide plate 4 is spent through 90, the volume of gas continues to diminish, but gas can not flow along the outer wall of cylindrical rotor 2, but the first passage 2c from cylindrical rotor 2 continues to move ahead, slip over 90 at main slide plate 4 and form a space when spending again, the gas that has had combustion gas begins to enter this space by the first passage 2c on the cylindrical rotor 2, for further work is prepared.

D). igniting: as shown in Figure 3, spend near 150 when main slide plate 4, when secondary slide plate 5 was spent near 90, this space was sealed, and spark plug 7 is lighted flammable pressurized gas.

E) burning work done process: as shown in Figure 5, in seal container, having only main slide plate 4 is movably, its thrust is that the area that main slide plate 4 is showed in this container is taken advantage of explosion pressure, pressure in this container rapidly increases to 8 to 13 times, pressurized gas promote main slide plate 4 and continue rotation, and its pressure is to reduce along with the continuous expansion of volume, also the area of being showed in this volume along with slide plate and changing.And secondary slide plate 5 is after turning over 90 degree, because the effect of cam 3 and space pressure is also contracted in rotor 2b, so just making combustion gas have bigger space to expand does work, when main slide plate 4 forwards 250 to when spending, 7 to 9 times of the volume of its expansion the chances are when igniting volume, pressure also drops to 0.2-0.5MPa.

F). the exhaust scavenging process: as shown in Figure 6, when main slide plate 4 rotations were spent above 250, main slide plate 4 entered relief opening, the relief opening of 20 radians can be reduced to expanding gas near atmospheric pressure rapidly, when main slide plate 4 forwards 270 to when spending, pressure exhaust is over, and begins to enter intake process.Cross 270 degree when entering intake duct 1a at main slide plate 4,, slide between 275 to 330 degree, have a spot of waste gas to enter intake duct,, can not influence the air inlet quality, can ignore because amount is few at main slide plate 4 owing on the cylindrical rotor 2 two first passage 2c are arranged.Just begin to carry out the air inlet state at main slide plate 4, when secondary slide plate 5 also begins to stretch out rotor rollaway nest and is ready to complete air inlet under the effect of cam 3, the air in the another side space of main slide plate 4 is promoted by main slide plate 4, gas enters into the firing chamber of burning expansion just along the vent of the another side of cylindrical rotor 2, whole waste gas of the inside are blown away, while is the cooling combustion chamber also, has so just finished a work cycle of sliding rotary engine.

This sliding vane type engine is compared maximum characteristics with reciprocating engine be that compression ratio is little, relative explosion pressure is little, but the thrust of outburst is vertically to give power along the radius of rotor all the time in this motor, and it is stressed even than reciprocating engine, the angular range of acting is also close (from theory, reciprocating engine 720 degree actings 180 degree, and oval sliding vane type engine 360 degree acting 95-100 degree), stress surface during acting big (with piston type with the air displacement size), so the output of engine shaft is changeed apart from not little, the commentaries on classics of motor is little apart from the impact amplitude, shakes little.Aspect startup, because compression ratio is little, do not need too big commentaries on classics distance during startup, the motor slide plate is finished an acting within 360 degree, can get angry once enclosing, so this motor needs energy seldom just can start when starting.The cooling aspect, in one-period, motor has individual scavenging function, mainly is the combustion cylinder cooling to motor, add that the shell of motor has cooling liquid further to cool off, and the cooling of slide plate and rotor is by finishing at the lubricating oil of rotor center part.The control of igniter is by the control of the rotational position of motor, and feeding and controlling of fuel also is that position by motor is controlled.From material, the slide plate of this motor should adopt high temperature resistant, and warping resistance degree height is wear-resisting, and good seal performance has the material of self-lubricating function, as the silicon nitride high strength ceramic material.Control from integral body, the control of this motor is its exclusive effect of competence exertion precisely, preferably by industrial chip computer control.
