Description

Plunger-rotating type engine

Plunger-rotating type engine belongs to a kind of power equipment, can be used to provide for automobile and miscellaneous equipment the new type gasoline engine of power.

The all in the past motor of the present invention almost is the Reciprocating engine of existing last 100 years history except small part belongs to the rotary engine that also will continue to develop all.This class motor exists a series of fundamental drawback, four stroke engine for example, and bent axle will change for two weeks (720 degree) and just do work once.And because motor has structures such as bent axle, connecting rod not only to make structure complicated, body huge etc. but also limited the raising of engine speed.Though neoteric rotary engine had power-to-volume ratio big than Reciprocating engine in nearly 20 years, vibrate series of advantages such as slight, simple in structure, flammable low octane value gasoline, but still existing low-speed performance difference and less economical, startability and durability remain problems such as improvement.The objective of the invention is problem such as not high at above-mentioned Reciprocating engine rotating speed, that structure is huge, structural manufacturing process is complicated and the severity of rotary engine pistons work and full machine Economy be bad and develop that the present invention is this to have efficient, high rotating speed, a plunger-rotating type engine simple in structure.

The main feature of plunger-rotating type engine is to rotatablely move and reciprocating combination, promptly along the cylinder barrel of particular curve ring track walking with and pto fuse and move reciprocatingly between the plunger of high speed rotating of formation rotor.The working method between plunger and the cylinder barrel and the Changing Pattern of active chamber just in time meet the quartastroke engine working law.During engine operation, gas blow-through pressure directly promotes plunger and drives the garden cylindricality pto outputting power of the tape spool shoulder that the rotor that constitutes with plunger connects together.When up the taking a round of track of cylinder barrel design along distribute needing according to the motor work done four-stroke time, just in time do a to-and-fro motion between plunger and the cylinder barrel, finishing once acting and also driving pto simultaneously and rotate a week.

Below in conjunction with accompanying drawing design of the present invention is described.

The major component of full machine work done is plunger [31] in the rotating part shown in Figure 2 and the cylinder barrel [30] that moves along guide rail [1] that moves reciprocatingly.

The rotating part of full machine (Fig. 1) also comprises distribution cam [5], outlet pipe [8], cooling fan [11], the flywheel [16] that is with starting gear ring [17], pto [21] and oil pump gear ring [24] etc. except the rotor [6] that is together formed by each plunger [31] casting.

Intake valve [41], intake duct [42], exhaust valve [43], air outlet flue [44], big little spring [47] and tappet are arranged in each plunger (Fig. 3).The outside that also has cooling oil duct [45], plug on the plunger studs with three seals ring [46] (i.e. two road compression rings, one oil ring).Several plungers that full machine determines according to needs such as power and rotating speeds all at root by cast solid (claiming rotor [6]).

The garden cylindricality pto [21] that is positioned at outlet pipe [8], rotor [6], the tape spool shoulder on motor (Fig. 1) top is to fuse by the big screw [12] that head is imbedded hole, shaft shoulder garden.For reducing exhaust resistance, pipe can be bumped into refractory ceramics pipe [9] in the outlet pipe, and outlet pipe is with cooling fan [11] and the distribution cam [5] that connects by key [7] outward.

It is a big advantage of this machine that the end has the pto [21] of spline [18] not need very long just available lock screw [19], pin [20] or ringfeder directly to be connected with flywheel [16].

It is a great revolution of motor that motor of the present invention does not need bent axle, bar linkage structure to claim, because even the rotary engine that is continuing now to develop also can not fully phase out bent axle, just on the molded lines of bent axle, change to some extent, this motor has cancelled that volume is big, Heavy Weight, processed complex, crankshaft rod structure that technological requirement is high, the length of axle is shortened greatly, make undoubtedly that full body is long-pending to be reduced, weight saving, increase and exert oneself, improve rotating speed etc. and bring series of advantages.

The rotating part of this motor (Fig. 1) also comprises the inner ring of three bearings, promptly be used for supporting rotor, prevent rotor axial and radial-play upper and lower roller bearing [4], [23] inner ring and to be loaded on the pto bottom be the inner ring that prevents the roller bearing [22] of pto swing.

Cylinder barrel of the present invention and plunger number are decided according to output power and rotating speed etc., therefore can make 1,2,3 ... each cylinder number.

Cylinder barrel (Fig. 1) as reciprocated part, the spark plug [29] that can contact with high pressure section board [28] periodically is equipped with on its top, and respectively there are spool [2] and spool [25] that the centrifugal roller of being made by brass [26] is installed that can install as the roller bearing [3] of work done guide wheel in cylinder barrel [30] bi-side.Axle [2] should be tried one's best near the bottom of cylinder barrel, to guarantee the stability of plunger when cylinder barrel moves, avoids slide.

Work guide wheel (Fig. 1) [3] just is being with cylinder barrel [30] to walk along guide rail [1] from engine start, because of the distance of each point on the guide rail and rotor center point needs be designed to constantly change by engine operation, thereby between the plunger that cylinder barrel and its overlapped of guide rail walking, also constantly changing relative position, thereby can finish the four-stroke acting.Centrifugal roller [26] only works and works at engine start moment (in a few times in second).This be because the moment of motor drives engine start motor rotating speed not high, the centrifugal force of cylinder barrel is not enough, thereby can not make each to obtaining the distance of necessary work between cylinder barrel and the plunger, motor just can not be worked voluntarily, thereby must be by the centrifugal force of centrifugal guide wheel increase cylinder barrel, cylinder barrel and plunger are drawn back in pressure, realize necessary work done distance and the beginning work done.Behind the motor normal operation input, cylinder barrel has enough centrifugal force, and the work guide wheel is normally moved along guide rail.Centrifugal guide wheel just no longer works and works.Owing to the existence of centrifugal guide wheel, guarantee that cylinder barrel can not fall naturally, and rational distance between maintenance and plunger is convenient to the startup next time during shutdown.

Another vitals of this motor (Fig. 1, Fig. 5) is respectively with upper and lower casing cast solid or be installed in respectively on the upper and lower casing and made by heat-resisting, high-abrasive material, the guide rail [1] of the consistent position of the good a pair of shape of structure stability symmetry.It is a ring track, and trade shape needs according to each stroke time distribution of four stroke engine and designs.For example air-breathing is different with compression stroke and each stroke of work done and exhaust the most rational shared time, and it also is uneven distributing in the time in each stage of each stroke, thereby the shape of guide rail not only is not the ellipse garden of positive garden or rule, and also be different at the track of each section of guide rail, could determine through careful calculating, design.The sectional shape of guide rail is will wait according to the needs of mechanical strength, way rub and Economics of Processing to design.

The electrical distribution system of motor (Fig. 4) is to control by the outer distribution cam [5] of outlet pipe [8] that is installed in rotating part.Though this is to contact bigger surface of contact and long time of contact owing to be contained in the high pressure section board [28] with on being contained in casing in spark plug [29] cycle at cylinder barrel top among the present invention, yet in order to prevent owing to oily unclean conduction that is contained in the casing, therefore the switching of high voltage circuit does not rely on the contact in the casing, and is come connection, the cut-out of the outer contact of controller by the polygonal distribution cam identical with the cylinder number outside the casing.When high voltage circuit [52] was connected, low-voltage circuit [51] cut off.When this motor is designed to use rotating speed is more than 7000 rev/mins the time, must adopt electronic ignitin system to adapt to needs at a high speed.

The distribution of this motor (Fig. 5) is to be mounted on a pair of intake cam [61] and the exhaust protruding [62] that extend on the lower housing near on the sleeve at center to control.The molded lines of two cams designs according to the distribution process need.Flow inlet angle and exhaust angle are designed to respectively suit about 120 degree and about 60 degree.Replace the pair of pistons of the motor that uses now, the structure that cylinder just has a pair of inlet and outlet cam by the only a pair of inlet and outlet cam of full machine, obviously be very big progress, new structure is not only simple, simple installation, rigidity also can improve greatly, help reducing the volume of motor undoubtedly, improve life-span, the reduction cost of motor, especially help motor and improve rotating speed.Because valve cam does not rotate among the present invention, but the valve tappet in plunger [63] is around cam rotation, therefore push the moment that valve tappet contacts with valve tappet at cam, valve tappet will be subjected to a lateral pressure or meaning lateral impact, what the bending tappet was arranged may or influence the tappet life-span, so valve tappet should be designed to shortly and thick among the present invention, this allows on the structural configuration of this machine and can accomplish.

Can the lubricated and cooling problem of motor usually become motor and realize design power, even a major issue that proper functioning.People make great efforts, try every possible means to improve design for the cooling that improves motor, lubricated doing always, realize reducing the temperature rise of each critical component, exert oneself with increase, improve the life-span.Lubricated, the cooling problem that people are continuing the rotary engine developed also still one remain the problem that further solves.The inventor just pays close attention to lubricated and cooling problem when the present invention is carried out structural framing.

Here preliminary consideration has three approach, that is:

Oil cooling but, lubrication system (Fig. 6), the oil pump gear ring [24] that rotates drives oil pump [71], be divided into two-way behind the oil groove [73] of the machine oil that pumps in machine Outer Tube [74], oil radiator [13], upper casing foundry goods, one route plunger oil duct through plunger advance, oil expulsion channel [45] flows into and is deposited in the motor lower casing [72], because the rotation of rotor takes up machine oil again to swash through machine oil guide plate [27] and splashes above guide rail [1], work guide wheel [3] and the cylinder barrel [30] etc., returns oil pump [71] again ... continue circulation again.Another Lu Zejing rotor casting [6], pto [21], valve cam [61,62], valve tappet [63], lower bearing [22] continue circulation after turning back to oil pump [71] again.

2. air cooling system: the wind scooper outside casing [13] guiding cooling casing [14] [16] again behind the machine oil of the cold wind cooling machine oil radiator [13] that cooling fan [11] is heaved.

3. take heat out of by Carburetor: constantly send into cool air in upper casing (Fig. 7) side through air-strainer interface [83], upper casing [14] opposite side is constantly extracted hot air out through the interface [81] of Carburetor, takes away heat in the machine.

The shell of this motor is owing to be subjected to inside that the influence of rotating part is arranged, can only be formed by connecting by two half flat garden shapes or half ellipse garden upper and lower enclosure [14] [16], certainly on the casing position structure to be arranged, must add seal ring between the upper and lower casing and connect through screw [15].

The suction tude of this machine [82] is positioned at the casing below and communicates with the intake duct of plunger.

Find out that from the each part mentioned above structural framing motor of finishing according to the present invention's design should be a vertical type,, be well suited on automobile and install, use from the bottom outputting power.This motor compare with the motor that uses now cancelled these complex structures of bent axle, connecting rod and valve cam, mechanical strength not high, influence rotating speed ... parts, this motor not only can make any cylinder number (1,2,3 ...) and rotating speed high and steadily, simple in structure.Again because the track of guide rail is depended in the distribution of each stroke operating time of each cylinder, thereby each section travel time is the most reasonably distributed, thereby reach the maximum of exerting oneself, fuel is economized most, the exhaust emission minimum, and work done is steady, and volume is little ...In addition, preresearch estimates, the pto of this motor is corresponding weak point many also, for example compare with 212 motors:

Motor	Cylinder diameter	Stroke	Pto ∮ L	Power
					212	92	92	66，100	70 horsepowers
This motor	80	80	60, about 17	About 140 horsepowers

Although this engine charge pipeline is long, resistance is bigger, from strengthening compression ratio, it is soluble reducing combustion chamber volume or using pressurized machine.Motor of the present invention can also be made high rotating speed or low-speed big, and might form series of advantages such as series product easily according to the output power needs, therefore it to replace the efficient of using now not high, volume is big, and just being tending towards that potentiality dig most Reciprocating engine and developing still can not the desirable rotary engine of using.It has pointed out a new direction for the development of internal-combustion engine.Will obtain good economic benefits and social benefit.
