Description
The Crankless piston internal-combustion engine belongs to field of internal combustion engine.
Common internal-combustion engine is many to be made up of piston, cylinder, connecting rod, bent axle etc.Owing to have no matter crank mechanism (is two stroke IC engine, or quartastroke engine), thereby having dead unit problem inevitably, the beginning bent axle in the most favourable period of explosion stroke almost is in the dead center position, so a large amount of fuel combustion heat energy fails to be converted into mechanical energy; Also strengthened simultaneously the physical dimension (because wanting the static instantaneously blasting impact that bears) of bent axle.In order to address this problem, someone had once designed a kind of rotary internal combustion engine, it changes the structure of former internal-combustion engine, parts such as bent axle, connecting rod have been cancelled, collect air-breathing, compression, explosion, exhaust stroke and in a ring, circulate and carry out, order about the rotor high-speed rotation that being loaded in the annular of garden with output mechanical energy.Owing to rotor and garden circular cylinder, the sealing problem of two end cap can not finely solve, so the internal-combustion piston engine of inventing more than hundred year is used till today always.
The utility model provides an approach for the efficient that improves internal-combustion engine, it has successfully cancelled crank mechanism, piston is directly linked to each other with rocking bar by connecting rod, make output shaft make one-way rotation by mono-directional overrun clutch, thereby fundamentally solved the dead unit problem of crank mechanism, as the length that adopts rocking bar equals the length of piston stroke, and Shu Chu merit can bring up to 0.93 from 0.5 so.
Enforcement of the present utility model in conjunction with the accompanying drawings, be further described (in order to give top priority to what is the most important, the distribution device that is widely used in now on quartastroke engine, the two stroke IC engine, oil pump, oil spout, vaporization mechanism have been omitted in convenient narration in the accompanying drawing and other do not have very essential parts for the explanation working principle).

Fig. 7 is left mono-directional overrun clutch schematic representation.
Among the figure: the 1.a piston rod; 2. public rocking bar; 3. left mono-directional overrun clutch (it is single to be called for short a left side); 4. left moving axis; 5. left gear; 6. internal gear (or middle gear); 7. output shaft; 8. right gear; 9. right moving axis; 10.C piston rod; 11, right mono-directional overrun clutch (being called for short right single); 12. slip rocking bar; 13.b piston rod; 14.d piston rod; 15.16,17,18 cylinders; 19. star-wheel; 20. garden post roller; 21,24. flat keys; 22 Hou rocking bars, 23. inside lefts shake, 25 inside right forwards shake, 26. outer hubs; 27. preceding rocking bar.If internal-combustion engine is before work, a, b two-piston are in (18), (17) two cylinder top dead center positions respectively, because connecting rod (1), (10), (13), (14) are hinged on public rocking bar (2), so C, d two-piston are in the bottom dead center position of (16), (15) two cylinders respectively.During startup, by starting distributing valve, pressurized air is made a forcible entry into the top of cylinder (18), promoting a piston moves downward, and make angle of public rocking bar (2) inverse clock rotation (60 degree) by connecting rod (1), because the effect of a left side single (3) causes also inverse clock rotation equal angular of left moving axis (4), the rotation of left side moving axis (4) has driven the rotation of its left gear that tightens (5), and rotation direction is identical with left moving axis (4) with angle; The rotation of left gear (5) has driven the rotation with the internal gear (6) (or middle gear (6)) of its engagement, the output shaft (7) that is fastenedly connected again, and rotation direction identical with left moving axis (4) (or opposite), and angle of swing equals 60 * Z
A left side/ Z
InDegree (or 60 * Z
A left side/ Z
InDegree), when a piston moves downward, because connecting rod (1) and connecting rod (13) are hinged on the public rocking bar (2) of the left singly left end of (3) simultaneously, so b piston and a piston move downward simultaneously, finish the suction stroke of cylinder (17) therefrom, meanwhile, C, d piston move upward by connecting rod (10), (14) and the public rocking bar (2) that together is hinged on the right-hand member on a left side single (3) respectively, finish compression, exhaust stroke respectively.The slip rocking bar (12) that is slidingly connected with public rocking bar (2) is angle of clockwise rotation (60 degree) then, but because the effect of right single (11), right moving axis (9) different slip rocking bars (12) rotate together, but by doing the inverse clock rotation with the drive of the right gear (8) of internal gear (6) (or middle gear (6)) engagement, angle of swing equals 60 degree.Work as a, the b piston moves to lower dead center simultaneously, C, when the d piston moves to top dead center simultaneously, the gas of C Piston Compression cylinder (16) is to minimum and pressure reaches certain numerical value, temperature increases, high pressure oil is chewed commencement of fuel injection, produce explosive combustion, gas volume immediately enlarges, produce powerful thrust, promoting the C piston moves downward, at this moment public rocking bar (2) is under the effect of connecting rod (10), and the clockwise rotation makes right moving axis (9) by slip rocking bar (12) and the right singly effect of (11), right gear (8), internal gear (6) (or middle gear (6)) and output shaft (7) inverse clock (or clockwise) rotation.The d piston moves downward in company with the C piston and finishes suction stroke.Meanwhile, a, b piston move upward, and finish exhaust, compression stroke respectively.So far public rocking bar (2) and slip rocking bar (12) have been finished a circulation, and quartastroke engine is also only finished half cycles.What follow down is that public rocking bar (2) carries out next one circulation as required, and cylinder, piston are finished down half cycles.That is: a, b piston are finished air-breathing, explosion stroke respectively, and C, d piston are finished exhaust, compression stroke respectively.Going on is that a, b piston are finished compression, exhaust stroke respectively again, and C, d piston are finished air-breathing, explosion stroke respectively.Cylinder, piston are just finished a circulation till having only by this, and public rocking bar (2) and slip rocking bar (12) have been finished two circulations, and so circulation is gone down, and drives the unidirectional rotation of output shaft (7), thereby reaches the purpose that heat energy is converted into mechanical energy.As previously mentioned, moving downward of connecting rod (1) is not to produce explosive combustion because cylinder (18) compressed air is met the high pressure plug cock during the first circulation beginning, promote that a piston produced, but because (or being equipped with electrical pump) pressurized gas of storing in advance by means of external system enter by starting distributing valve that cylinder (18) finishes.After the second circulation beginning of cylinder, start distributing valve and no longer work, and a piston has also possessed the next circuit condition of carrying out.It is top that what narrate is the working condition of diesel engine, obviously for four-stroke gasoline internal-combustion engine and two-cycle gasoline internal-combustion engine and two-stroke diesel combustion engine, this model utility is suitable equally, because with regard to its essence, this model utility has just replaced crank mechanism with rocking bar, other mechanisms of now full ripe four-stroke, two stroke IC engine all can use naturally, and Just because of this, the narration of front does not just relate to such as distribution device and oil spout mechanism etc. yet.For the power of increasing combustion engine, quartastroke engine can be provided with eight cylinders, twelve-cylinder etc.; Two stroke IC engine can be provided with four cylinders, six cylinders, eight cylinders etc.
The working principle of left side mono-directional overrun clutch (3) 7 outlines in conjunction with the accompanying drawings is as follows: when public rocking bar (2) is pressed the direction rotation of solid arrow indication (inverse clock), garden post roller (20) is pulled to narrower place between star-wheel (19) and the outer hub (26), drive outer hub (26) inverse clock by flat key (21) and rotate, the rotation of outer hub (26) drives also inverse clock rotation of left moving axis (4) by flat key (24) again.When public rocking bar (2) is pressed the direction rotation of dotted arrow indication (clockwise), garden post roller (20) is pulled to the place of broad between star-wheel (19) and the outer hub (26), so outer hub (26) is thrown off with star-wheel (19), left moving axis (4) will keep original rotation direction owing to right mono-directional overrun clutch (11) effect.The working principle of right mono-directional overrun clutch (11) is identical therewith, different just staggers on the operating time each other, promptly when the band moment of torsion work of a left side single (3), right single (11) backlash is changeed, and during the work of right single (11) band moment of torsion, single (3) backlash in a left side is changeed, and so exchange work causes output shaft (7) to rotate continuously, with output torque.
Fig. 5, Figure 6 shows that the distressed structure of Crankless piston internal-combustion engine, the Crankless piston internal-combustion engine of its working principle and Fig. 1 to Fig. 4 basic identical, here only be illustrated: when a piston is moved downward by the thrust of gas in cylinder (18) with regard to different places, make angle of preceding rocking bar (27) inverse clock rotation by connecting rod (1), because the effect of a left side single (3), output shaft (7) also rotates an identical angle, (also just because of the effect of the right side single (11), Hou rocking bar (22) can dextrorotation.) right-hand member of preceding rocking bar (27) causes connecting rod (10) to move upward and finish the compression stroke of cylinder (16), simultaneously, before rocking bar (27) contrary revolve and cause the inside left to shake the contrary of (23) to revolve (to the left) from the right side, the inside left shakes the contrary conrotatory of revolving and cause the back rocking bar (22) that becomes higher pair with it of (23), makes cylinder (17), (15) finish exhaust, suction stroke respectively by connecting rod (13), (14).When the gas compression of cylinder (16) to hour, temperature rises, the oil injecting nozzle commencement of fuel injection produces the explosion burning, promotes the C piston and moves downward.The effect by four rocking bars and four connecting rods of moving downward of C piston makes cylinder (18), (17), (15) finish exhaust, air-breathing, compression stroke respectively.After the compression stroke of cylinder (15) is intact, be right after the explosion stroke, so that finish respectively cylinder (18), (17), (16) is air-breathing, compression, exhaust stroke, after cylinder (17) compression stroke, be right after the explosion stroke again, so cylinder (18), (16), (15) are finished compression, air-breathing, exhaust stroke respectively.From the order of above-mentioned power stroke as can be seen (being the explosion stroke) is (18), (16), (15), (17), and circulates down by this, revolves so that output shaft (7) is contrary continuously, with output torque.The front and back rocking bar becomes hinged with four pistons, and two rocking bars are with two auxilliary four higher pairs that shake into.
