Description

Rotary engine

Technical field

The invention relates to a kind of rotary engine, particularly improve delivery efficiency, reduction operation friction and fuel consumption, make the rotary engine that simple elasticity increases number of cylinders but also have simultaneously about a kind of

Background technique

Shown in Figure 22 is existing engine, and reciprocating piston engine 100 is in a space of fixing, and alternately carries out air inlet, compression, outburst and four kinds of work of exhaust, exports by the power of the 110 conversion generation rotations of the cranks in the engine 100.The operation principles of this conventional engine 100 is used in daily life today in a large number, no matter be the means of transportation that is used for land, sea, air, still is used for all kinds of power equipments of agricultural, industry and even national defence, all is to use this engine.Yet, though this reciprocating type engine 100 extensively uses,, exist following defective and demand urgently breaking through no matter be two-stroke or four-stroke engine:

(1) delivery efficiency be difficult for to promote: the output of reciprocating type engine 100 be with its bent axle 110 with the linear motion of piston 120 convert to rotatablely move after, connect with external system again, linear motion is converted to the reduction that the process that rotatablely moves will certainly cause delivery efficiency, and this structural restriction has caused the lower problem of delivery efficiency to be difficult to solve.

(2) structure is complicated with manufacturing: the height of reciprocating type engine 100 delivery efficiencies, with the height of its crank 110 accuracy of manufacturing very big relation is arranged, just the crankshaft in this crank 110 112 requires to have high precision with crank pin 115 on making, if its accuracy of manufacturing produces error, its conversion efficiency can be subjected to great influence.Now the reciprocating type engine with four cylinders is an example, and its inside needs 40 accurate parts that cooperatively interact at least, just can reach effect preferably, and this factor causes its manufacture cost high.

(3) the horsepower increase causes fuel consumption to increase: reciprocating type engine 110 can borrow lengthening its arm of force, the method that just increases connecting rod 117 length on its crank 110 increases its horsepower, if the arm of force increases, volume potential necessity of cylinder 125 increases in the lump, and then also will cause the increase of fuel consumption, make shaft horsepower with reduce fuel consumption and can't get both.

(4) increasing number of cylinders is restricted: when reciprocating type engine 100 increases cylinder 125 numbers to improve horse-power-hour, the unavoidable volume that will increase whole automotive engine system.No matter this cylinder arrangement mode is to adopt horizontal, vertical, tilting or other spread pattern, as V formula, W formula or H formula etc., all can't solve increases the problem that volume that number of cylinders causes increases.

(5) friction problem that runs up: for the reciprocating type engine 100 that runs up, its rotating speed may be up to more than the 2000r.p.m., run up and make the piston 120 that moves reciprocatingly bear great frictional force, also produce simultaneously a large amount of heats, be easy to make its part impaired and lower engine life, simultaneously also and then increase the fuel consumption of engine.

There is (delivery efficiency) problem for solving among (1) of above-mentioned conventional reciprocating formula engine 100, nineteen twenty-four Germany engineer Felix Wankel has invented famous Wankel rotary engine 150, this invention is as shown in Figure 23, the eccentric rotor 160 that has adopted a triangular shape is in an air chamber center 165 rotations, piston 120 and cylinder 125 in the reciprocating type engine 100 have been replaced, and borrow the air chamber curve of its particular design, this three-apexed rotor 160 is rotated a circle promptly finish air inlet, compression, outburst and exhaust four stroke in the lump.Because the power of these Wankel engine 150 outputs can directly use rotatablely moving of rotor 160 without conversion, has significantly improved the low problem of delivery efficiency that reciprocating type engine 100 has; Generally speaking, Wankel engine 150 its power outputs of same air displacement will be the twices of reciprocating type engine 100, and the component part of its engine also significantly reduces, therefore, 1958 of volume production play the shock that promptly causes industrial circle for the first time at it, especially in the sixties of pursuing power, the Wankel engine with high delivery efficiency is used to sport car, create the speed per hour record of sport car time and again, the situation that replaces conventional reciprocating formula engine 100 is arranged greatly.

Yet,, but still can't solve above-mentioned (2), (3), (4) problem that exists though Wankel rotary engine 150 has improved some shortcomings of reciprocating type engine 100.This is because the revolving grate and the irregularity of three-apexed rotor 160, diaphragm seal 170 under high speed rotating on three of this rotor 160 drift angles has born great friction, if it is poorly sealed, can cause explosion chamber gas leakage, and then make power run off and the oil consumption increase, and this problem is serious day by day along with the increase of service time, even the per 30,000 miles engines that just will clear up cylinder or more renew.This fatal shortcoming makes its oil consumption and CO (carbon monoxide converter) emission far above traditional reciprocating type engine 100.Simultaneously, though the component that Wankel engine 150 uses lack than reciprocating type engine 100, but the internal gear 180 in its three-apexed rotor 160 needs high accuracy of manufacturing equally with external gear 185, reduction effect for manufacture cost is limited, and this three-apexed rotor 160 is the most flimsy parts in the whole engine, thereby cause Wankel engine 150 almost one to have damage promptly to need integral replacing, its user cost exceeds people's expection far away.Hence one can see that, though Wankel engine 150 has been broken through the restriction of the reciprocating type engine 100 of part, produced the unexistent shortcoming of conventional engine also, makes it not reach people at the beginning to its expectation popularizing of market.

Energy crisis in 1973 and day by day surging at that time environmental requirement, transfer the R﹠D direction of car engine to pursuit fuel-economizing and low the pollution by high oil consumption, the high-performance pursued originally, the shortcoming of Wankel engine is highly amplified under this historical background, the development plan of cancellation Wankel engine in surging criticism sound one after another of each automobile factory, recovered the production of traditional reciprocating type engine again, the improvement that finally only remaining Mazda (Mazda) tame depot still adopts the Wankel engine and continues to carry out its performance breaks through; Though the RX7 car money that Axela Inc. in 1999 releases adopts the drift angle diaphragm seal of modern oiling agent and stupalith, has reduced the loss problem of Wankel engine, this improvement has increased manufacture cost undoubtedly, the shortcoming of deriving again and making new advances.

In addition, from the development experience of Wankel engine, we also can find the birth of any new product, except must possessing the advantage and effect that common technology do not have, the construction of its manufacturing mechanism and production line is simpler and easy and low-cost, otherwise can't stimulate the exploitation wish of original industry MANUFACTURER at all; Inspect the developing history of Wankel engine, can find the processing difficulties of its three-apexed rotor and it and conventional reciprocating formula engine manufacturing mechanism far from each other, it can't attract the main cause of original production firm just for this.

In sum, how to design a kind of simple and lower-cost brand-new engine of making, make its delivery efficiency be higher than traditional reciprocating type engine at equal conditions, can reduce simultaneously friction and oil consumption, also possess souping under the situation that fuel consumption does not improve and can under the prerequisite that does not increase the engine volume, increasing advantages such as number of cylinders, be undoubtedly the important research and development problem of current whole engine industry or automotive industry.

Comprehensive above-mentioned four embodiments' explanation can be confirmed the shortcoming that rotary engine 1 of the present invention can improve existing reciprocating type engine and Wankel rotary engine really, and the effect that it reached and the problem of solution can comprehensively be described as follows:

(1) delivery efficiency height: the explosive force among the present invention after this spark ignitor is directly to promote this revolving cylinder, is passed in this drive rotating disk and first rotating shaft again, and its output usefulness obviously is better than the reciprocating type engine that need change; And the rotation of drive rotating disk of the present invention, more smooth-going than the operation of the three-apexed rotor of Wankel engine, the operation process friction is less, the tangent direction when the outburst outlet of this lighting-up tuyere approaches this drive rotating disk rotation again, and therefore outburst back power output usefulness also is better than the Wankel engine far away.

(2) structure is simple with manufacturing: component part of the present invention is simpler than conventional reciprocating formula engine, compare with the Wankel engine, rotational action of the present invention does not need gear driven or the correcting by precision yet, and this revolving cylinder and power piston sheet are to be rotated in a circular track, the driving wheels of this drive guide wheel group then are to be rotated in an elliptical orbit, its design and manufacturing are all simple than the three-apexed rotor of Wankel engine running track special with it, and these characteristics help industry of the present invention to promote.If canvass the reason that the Wankel engine can't expand then, except the shortcoming of height friction, high oil consumption, it makes difficult and the manufacturing mechanism costliness also is a big reason, and the risk of changing production line is reluctant to bear by this traditional depot that causes making reciprocating type engine.Yet the present invention is owing to possess structure and make characteristic of simple, required production line and equipment also easily construction finish the problem that the Wankel engine of can fully solving over faces.

(3) can increase engine horsepower and can not increase fuel consumption: when reciprocating type engine increases its crank arm of force or Wankel engine and increases its rotor size, all can increase the shaft horsepower of this engine, this also increases the import/exhaust space of volume and its cylinder of these two engines simultaneously, and then causes the increase of fuel consumption; In design of the present invention, when the artificer will be when the major and minor axis ratio that increases this drive rotating disk radius or change this elliptical orbit increases air inflow or engine horsepower, second containing space in this revolving cylinder still can be kept original volume, and the fuel consumption of engine running is risen.

(4) but elasticity increases the cylinder number: when single reciprocating type engine (only having a cylinder) and single Wankel engine (only having three cylinders) will increase its horse-power-hour, often to increase engine quantity such as different arrangement modes such as V-type, W type, and then increasing its cylinder number with one or three multiple, this will increase the material of engine occupation space and use; In the design of the present invention, the mode that engine increases cylinder has elasticity, only needs like that as shown in figure 21, and the quantity that increases this revolving cylinder in this stationary cylinder gets final product (accompanying drawing to increase to three cylinders respectively and four cylinders are example); Perhaps also can adopt the revolving cylinder quantity in each stationary cylinder constant, and increase the quantity of stationary cylinder and design the mode of different fixing cylinder phase difference, make it have different explosion times and reach, can adopt which kind of configuration mode according to the size decision of this stationary cylinder and revolving cylinder to same effect.For example: when designing a six-cylinder car engine, can adopt six revolving cylinders all are installed in the stationary cylinder; Also can adopt three revolving cylinders of installing (ignition location need have the phase difference of 180 degree) in two stationary cylinders simultaneously; Also can adopt two revolving cylinders of installing modes such as (ignition location need have the phase differences of 120 degree) in three stationary cylinders simultaneously, decide according to user's system space and manufacture cost.

(5) lower operation friction: many particular design of each parts of the present invention all consider to make the friction of operation process to minimize, and for example this power piston sheet are fixed in this second rotating shaft, make its not reason displacement and produce friction; The radius that perhaps makes this drive rotating disk is less than this stationary cylinder internal diameter; The sectional area that makes this first, second rotating shaft is less than the penetration hole area on this guide channel cover plate, the drive rotating disk; And driving wheels (big or small runner) particular design of this drive guide wheel group etc., all can avoid directly contacting between each parts the frictional force that is produced; Therefore, in the engine running process of the present invention, the diaphragm seal that ball bearing, ball bearing is only arranged and be installed on this revolving cylinder, the power piston sheet has friction-produced, and because the running of this drive rotating disk is a level and smooth circle, friction on the sealing sheet can be minimized, and the degree of wear is far below the diaphragm seal on three-apexed rotor three drift angles of Wankel engine.

(6) sealing effect is good: all be equiped with a plurality of diaphragm seals on revolving cylinder of the present invention and the power piston sheet, can run up and reach paramount when hot at engine, produce thermal expansion and fill up gap between this revolving cylinder and stationary cylinder and this power piston sheet and the revolving cylinder, and then prevent the gas leak phenomenon in this import/exhaust process; Simultaneously, when the flow of lubricant that lubricating fitting sprayed that the present invention disposed through around the sealing sheet time, also can further strengthen the sealing effect of sealing sheet.

(7) lubricated convenient and with low cost: the designed lubricating fitting of the present invention has lubricated effect easily, centrifugal force when the oil spout power of its lubricant oil is this first rotating shaft high speed rotating, the power of engine itself (external activation motor) just, the power equipment of this lubricating fitting need not be increased again in addition, manufacture cost and system weight can be saved; Simultaneously, the surperficial penetration hole design on the hollow bushing of this first rotating shaft, the lubricated distribution that also can make this lubricant oil is more evenly to bring into play maximum lubrication effect; In addition, the design of oil trap, pump and radiating fin in the opening of offering on the outer wall of this stationary cylinder and this lubricating fitting, more can make the high temperature grease that used cycling and reutilization repeatedly, with advantage convenient and that reduce cost, simultaneously the weight of this lubricating fitting can be minimized the load of unlikely increase engine.

(8) cooling is convenient and with low cost: the gas cooling type cooling method in this revolving cylinder finned and non-airtight configuration design that the present invention adopts, really can effectively improve cooling effectiveness.The window of offering on the hollow part of on the oil drainage hole of offering on this stationary cylinder or this guide channel cover plate and the surface that drives rotating disk, being offered and this revolving cylinder inwall etc. for example, can substitute water tank and other water cooling plant fully, simultaneously also can be by the lubricant oil of this lubricating fitting sprinkling, reinforcement is to the heat exchange and the cooling of each parts, fully reduce system space and weight, also can save the cost of manufacturing simultaneously.
