Description
Technical field
The present invention relates to the device that a kind of engine is used, in particular to a kind of electromagnetic booster for air power engine assembly.
Background technology
The power source majority that conventional generator system adopts is the piston-mode motor that adopts fuel oil.This employing fuel oil as the engine of power source on the one hand because oil inflame is insufficient, in the gas that makes to discharge, contain a large amount of harmful substances and contaminated environment, on the other hand because the fuel oil using is to refine and obtain from oil, petroleum resources day by day in short supply makes to be subject to increasing restriction as development and the utilization of the fuel engines of power source.Therefore develop new, clean, free of contamination alternative energy source, or reduce as much as possible fuel consume, reduce discharge and become urgent problem in development of engine.For this reason, various countries have experienced complicated and hard the Exploring Road, have researched and developed multiple power source, such as substitute fuel, motorized motions, fuel cell and solar cell etc.But, the equal Shortcomings part of hybrid power source that various new power sources or their form, thereby, in the urgent need to a kind of, there is no pollution, a nexhaustible novel energy, compressed-air power source has just in time met this requirement.
Study the earliest and take the designer Guy Negre as French MDI company of compressed air as power source, it has proposed the concept of compressed air engine, attempt to solve the problem of utilizing of " zero discharge " and the energy capable of circulation, from then on open the new page of engine research, and in 2002, released the pure aerodynamic Domestic bridge car of first item.Compressed air compressor is used high pressure air as power source, and air, as medium, when compressed air engine is worked, is converted to other forms of mechanical energy by the pressure energy of compressed air storage.The visible FR2731472A1 of research, US6311486B1, US20070101712A1 etc. about compressed air engine.
FR2731472A1 discloses a kind of engine that can work under fuel supply and two kinds of patterns of compressed air supply, on highway, adopt conventional fuel as gasoline or diesel oil, in low speed particularly urban district and suburbs, compressed air (or other any on-contaminated Compressed Gas) is injected to combustion chamber.Although this engine has partly reduced fuel consumption, owing to still having adopted fuel oil mode of operation, emission problem still fails to solve.
For further pollution abatement, US6311486B1 discloses a kind of pure air-powered motor, such engine has adopted three independently chambers: air-breathing-discharge chambe, expansion exhaust chamber and constant volume combustion chamber, and air-breathing-discharge chambe is connected to constant volume combustion chamber by valve, constant volume combustion chamber is connected to expansion exhaust chamber by valve.One of problem of this engine is that time of experiencing from air-breathing-discharge chambe to expansion exhaust chamber of Compressed Gas is longer, the power source gas time that obtains driven plunger acting is longer, simultaneously, the gases at high pressure of discharging from expansion exhaust chamber fail to be used, and this has just limited operating efficiency and the single aeration continuous working period of this class engine.
More domestic researchers and unit are also studied compressed air engine, but most concentrating in the feasibility and operation principle of compressed-air power engine, such as (" feasibility studies of Compressed-air Powered Vehicle " such as Xu Hong, < < China Mechanical Engineering > > the 13rd volume the 17th phase 1512-1515 page, in September, 2002).Though more domestic patent documentations are such as CN1851260A, CN100560946C, CN101705841A are also studied compressed air engine, but belong to theoretical research and conceptual design more, all fail to solve compressed-air actuated discharge and (conventionally there is higher pressure, such as about 30bar) and control and the assignment problem of high pressure air, from the commercialization process of compressed air engine, have got long long way to go.
The application's applicant discloses a kind of air power engine assembly that can be used for transport facility in its patent documentation CN101413403A (its international application of the same clan is WO2010051668 A1), and this engine comprises air accumulator, air distributor, engine, clutch, clutch, automatic transmission, differential mechanism and is placed in the turbo dynamo in exhaust chamber.This engine utilizes compressed air to do work and does not use any fuel, therefore there is no toxic emission, realized " zero discharge ", and recycling waste gas generates electricity, and has saved the energy, has reduced cost.But this engine is the four-stroke engine based on traditional, every rotation 720 degree of bent axle, piston does work once.And can promote piston acting as the pressure-air of power source can be in entering cylinder time, and then discharge, the stroke of compressed air engine is actual is air inlet-expansion stroke and discharge stroke.Obviously, the disclosed this four-stroke-cycle compressed air engine of patent documentation CN101413403 A has been wasted effective expansion stroke greatly, has limited the efficiency of engine.And the tail gas of this engine fails to recycle well, need enough large air accumulator deposit pressure-air could work the sufficiently long time, this has just reduced compressed air engine in industrial application prospect.
The air-powered motor that above-mentioned various research institutes propose is all while moving to lower dead center based on piston in cylinder, piston is driven from lower dead center and is continued to move to top dead centre by flywheel via the inertia of Crankshaft motion, thereby the compressed air in work chamber is discharged.Yet, because expanding in working chamber, compressed air promotes still there is larger pressure after piston acting, 3MPa for example, piston is only discharged the compressed air still with 3Mpa via the rotator inertia of bent axle and flywheel, " weak " just seems, when low engine speed is rotated, it is more outstanding that this situation just seems.In order to improve as much as possible the rotating speed of air-powered motor, need piston motion of high speed more in working chamber, and the steady torque output slowly running in order to improve air-powered motor, need to provide power assisting device for bent axle.
Conventional power assisting device adopts electromagnetism or permanent magnetism power assisting device conventionally at present.Chinese patent literature CN2512700Y discloses a kind of electromagnetic assistor for bicycle, and it is by the rotation of the interaction auxiliary wheel of magnet and electromagnet, thereby realizes energy-conservation and double effects power-assisted.Another Chinese patent literature CN1439560A discloses a kind of electromagnetic steering booster of vehicle, this power steering device has adopted electromagnetic booster, transducer, control module and power supply, signal that control module provides according to transducer changes the size of electric current on electromagnetic booster, to obtain good power-assisted effect when the automobile low speed.Another patent documentation WO2004009424A1 also discloses a kind of electric power-assisted steering apparatus that adopts solenoid, to alleviate driver's fatigue.Visible, adopt electromagnet or permanent magnet in many industries, to be on the actual application as the power assisting device of moving component.
The present invention aims to provide a kind of electromagnetic assistor for air power engine assembly, so that for engine crankshaft provides rotation power-assisted, thereby the stabilizing moment when promoting the high speed rotating characteristic of air-powered motor and slowly running is exported, and then improves the efficiency of air-powered motor.

Embodiment
The following description is only exemplary and be not in order to limit the disclosure, application or purposes in essence.Should be understood that, in whole accompanying drawings, corresponding Reference numeral represents identical or corresponding parts and feature.
Before describing the specific embodiment of the present invention in detail, first the energy with regard to compressed air engine carries out theory analysis.
The acting process of compressed air engine is fairly simple, the process of only having compressed air to expand and do work.As shown in Figure 12 A, Fig. 1-5 are compressed air isothermal expansion process, and 1-6 is compressed air adiabatic expansion.It can not be constant temperature process completely that compressed air does work in engine, conventionally between constant temperature process and adiabatic process, in order to improve compressed-air actuated capacity usage ratio, can adopt multistage adiabatic process to be similar to constant temperature process, or adopt the appearance endothermic process such as multistage to be similar to constant temperature process.Compressed-air actuated double expansion acting process 1-2-3-4 has been shown in Figure 12 A, and 1-2 and 3-4 complete in first cylinder and second cylinder.Working medium, after the adiabatic expansion acting of the first order, then is carried out isobaric heat absorption 2-3 through a heat exchanger, gets back to after initial temperature, then enters the acting of expanding of the second cylinder.Theoretically, can regard approx the acting process of engine as isothermal expansion process, so curve 1-5 and coordinate figure V
1, V
2between the energy of the cartographic represenation of area compressed air storage that comprises discharge the gas expansion merit that can change.And in Figure 12 B, in figure, curve 1,2 represents respectively compressed-air actuated isothermal, adiabatic expansion, actual puffing process is between curve 1,2.In figure, A is starting point, and B, C, D, E are the corresponding transfer pressure pressure classification point while controlling, and have endothermic process such as the appearance of grade, as BC and DE etc. at these some places.Theoretically, curve 1 and coordinate figure V
1, V
2between the energy of the cartographic represenation of area compressed air storage that comprises discharge the gas expansion merit that can change.
The blowing pressure of supposing high pressure gas holder is p
1, gas storage volume is V
1ideal gas in complete isothermal expansion to normal pressure p
2whole expansion works that Shi Suoneng does are:
In formula, (p
1, V
1) and (p
2, V
2) be initial, end of a period state accordingly, the end of a period state after adiabatic expansion is (p
2, V '
2).
The parameter of choosing French MDI company engine is initial gas storage pressure p
1=30MPa, gas storage volume V
1=300L, the pressure p under end of a period room temperature state
2=0.1MPa, can be calculated whole expansion work W=51.334MJ of the complete isothermal expansion between initial, end of a period state by formula (1), formula (2).
The working temperature of supposing compressed-air power engine is 300K, and the compressed-air actuated quality that can obtain under 300L, 300MPa air pressure is 104.553 kilograms, and the quality of supposing air accumulator is double centner, and corresponding specific energy is about 75Wh/kg.The on-vehicle battery of comparing, for example lead-acid battery and nickel-cadmium cell, it is high that compressed-air actuated specific energy is wanted, and equal substantially Ni-MH battery, has good development prospect.Along with the development of the large capacity of high pressure tank, large pressure and lightweight, compressed-air actuated specific energy also has raising significantly, even can approach sodium-sulphur battery and lithium polymer battery.
Compressed air has two kinds of acting forms in engine, i.e. isothermal expansion process and adiabatic expansion, below with both features of design parameter calculation specifications.
Choose initial condition 1 (30MPa, 300K), end of a period state 2 (0.1MPa, 300K), the expansion work of asking unit mass compressed air to do in constant temperature process and adiabatic process respectively.Isothermal expansion process unit mass gas institute work is W=491kJ/kg, and adiabatic expansion unit mass compressed air institute work is W '=242.3kJ/kg.From theory, calculated, the expansion work of constant temperature process is almost 2 times of adiabatic expansion, so the capacity usage ratio of isothermal expansion is higher than adiabatic expansion, and it is desirable adopting in theory isothermal expansion acting.But " isothermal " is to be difficult to realize in cylinder, must have a second heat conductance to enter engine machine wall to keep enough heats.This has just increased technical difficulty, makes engine structure complex.Further from compressed-air actuated energy, utilize angle to discuss to two of compressed air engine kinds of power distribution patterns below.
Under parallel way, the Compressed Gas of equivalent is input to each cylinder expansion acting simultaneously.If initial condition 1 (30MPa, 300K), end of a period state 2 (0.1MPa, 300K), compressed air carries out isothermal expansion in cylinder, and isothermal is similar to rate η=80%, number of cylinders is 4 cylinders, and the compressed air that enters engine is 1 kilogram of unit mass, and total technology merit that 4 cylinder gases are done is
Visible, although isothermal expansion process is desirable acting process, the gas volume after expanding is 300 times before expanding.This just needs the cylinder of acting must have very large volume.If the cylinder of the cylinder that adopts available engine after as isothermal expansion, selecting compression ratio is 10,
W＝198.3kJ/kg。Obviously, technology merit greatly reduces, the technology merit of not only doing not as adiabatic expansion, and also residual pressure is very high, and energy does not make full use of.But the advantage of parallel way is that each cylinder structure is measure-alike, arranges simply, and power output steadily.Consider current technology, cylinder can not keep complete isothermal, and the compression ratio of cylinder can not be done too much, the discharge pressure of Compressed Gas after the acting of expanding is higher, still can be used for continuing acting, therefore adopting multistage adiabatic process or closed loop to reclaim the energy of tail gas, is comparatively practicality at present, effective mode.
Under series system, by compressed air adiabatic expansion acting successively in each cylinder, the initial pressure that the Exhaust Gas of previous stage cylinder is next cylinder.Known through theoretical calculation analysis: serial graded is more, the series connection cylinder number using is more, and the compressed air institute work of unit mass is more, and capacity usage ratio is higher, and the level Four of generally connecting can realize 80% of complete isothermal expansion acting; In other series connection of ad eundem, the pressure value of intermediateness is different, not little to total technology work difference.The greatest problem of serial cylinders is that the volume of rear one-level cylinder is all greater than the volume of cylinder of previous stage, and all will load heat exchanger so that isobaric heat absorption between cylinder at different levels.Thus, increasing to the dimensional requirement of engine, can have a strong impact on the integral layout of the equipment that uses compressed air engine.
From upper analysis, compressed air engine is different from traditional fuel engines and various electric power device, and it is feasible in principle, and the strategy of sustainable development that meets environmental protection, economizes on resources.And, compressed air convenient sources, other forms such as that energy storage mode is better than is electric, hydraulic pressure.Compressed-air actuated power distribution form respectively has pluses and minuses, improves compressed air service efficiency, and increasing pressure pan capacity and the blowing pressure is to improve the Main Means of once inflating continuous working period.At tank, hold, the blowing pressure is relatively definite in the situation that, compressed air energy utilization rate η is maximum running parameter.The problems such as engine structure optimization, off gas energy recovery, compressed air distribution are the problems that needs further investigation.
Through above-mentioned theory analysis, the application's applicant adopts compressed-air actuated power allocation model in parallel, in order to improve the pressure of compressed air energy utilization rate and the rear Exhaust Gas of acting, applicant adopts tail gas recycling loop, and in order to improve high speed rotating characteristic and the output of low-speed stable moment of engine, adopt bent axle power assisting device.To be described in detail concrete mode of the present invention below.

Detailed structure and the operation principle of electromagnetic booster 1000 are described now.The different embodiment of electromagnetic booster 1000 of the present invention have been described in Figure 13-16.In Figure 13-16, identical mark represents identical parts.With reference now to Figure 13 A-13C,, Figure 13 A is the perspective view of a preferred embodiment of the electromagnetic booster of the electromagnetic assistant aerodynamic power generator system in Fig. 1, and it shows the situation of rotor and each 2 iron cores of stator; Figure 13 B is the front view of Figure 13 A; Figure 13 C is the sectional view that analyse and observe at the center of Figure 13 A.Electromagnetic booster 1000 comprises booster shell 1001, stationary part, rotor portion.Stationary part is comprised of stator core fixed disk 1002, stator core 1004 and stator core coil 1003.Rotor portion is comprised of rotor core fixed disk 1007, booster flywheel 1008, rotor core 1005 and rotor core coil 1006.Electromagnetic booster 1000 profiles circularize tubular, and booster shell 1001 is positioned at the outermost of electromagnetic booster 1000, its generally by NULL such as iron is made.The stator core fixed disk 1002 of stationary part is fixedly connected on booster shell 1001, and stator core 1004 is plugged on stator core fixed disk 1002, is wound with stator core coil 1003 on it.
Rotor core fixed disk 1007 is by interference fit or be threaded and be fixedly mounted on booster flywheel 1008, to rotate with booster flywheel 1008.On rotor core fixed disk 1007, be plugged with rotor core 1005, on rotor core, be wound with rotor core coil 1006.Booster flywheel 1008 is fixedly connected with bent axle 56 by key 1009.In exemplary enforcement of the present invention, booster flywheel 1008 is fixedly connected with bent axle elongated end 3071 by spline or flat key or pin 1009, thus make bent axle 56 rotarily drive 1008 rotations of booster flywheel and then 1005 rotations of rotor driven iron core.
By description above, can know, electromagnetic booster 1000 of the present invention is Split type structure, be that stationary part and rotor portion are partial installations, the benefit of partial installation is to simplify the structure of electromagnetic booster, and the installation, maintenance of rotor portion and stationary part and maintenance can be carried out separately.Although electromagnetic booster of the present invention 1000 adopts Split type structures, rotor portion and stator be cooperating well still.As shown in Figure 13 C, stationary part is fixedly connected with booster shell 1001 by stator core fixed disk 1002, such as being is threaded or interference fit, be that stationary part and booster shell 1001 do not exist movement relation each other, booster shell 1001 forms a fixed connection by the polygon lid 313 of the securing members such as the bolt through shell installing hole 1011 or screw and front gear box system 43, thereby stator is fixedly mounted on engine 1.And rotor portion rotates with bent axle 56 with being fixedly connected with of bent axle elongated end 3071 by booster flywheel 1008, thus, the stationary part of electromagnetic booster 1000 and rotor portion can harmoniously be worked.
In the electromagnetic booster structure shown in Figure 13, stationary part and rotor portion form by two iron cores, and 2 rotor cores 1006 that become 180 degree to place become the stator core 1004 that 180 degree are placed to form with 2.As shown in Figure 13 B, the active force producing for the electromagnetic field homopolar-repulsion that the rotor core coil 1006 of rotor portion and the stator core coil 1003 of stationary part are produced promotes bent axle 56 rotations, can suitably stator core 1004 suitably be tilted to install, such as stator core 1004 can be become to the acute angle angle inclination installation of 5 ° to 30 ° with respect to the extended line of rotor core 1005, preferably, angle of inclination can be 10 ° to 25 °, more preferably, angle of inclination can be 12 ° to 20 °.In preferred enforcement of the present invention, can select stator core 1004 is 5 °, 8 °, 12 °, 15 °, 20 ° with respect to the angle of inclination of rotor core.For the magnetic field that utilizes better coil 1006 and 1003 to produce, reduce iron loss, stator core 1004 is built up by silicon steel sheet, and rotor core 1005 is made or also by silicon steel sheet, is built up by whole steel.
Further describe now the operation principle of electromagnetic booster 1000.Why power-assisted is that it has utilized the magnetic signature that between electromagnet or permanent magnet, homopolar-repulsion heteropole is inhaled mutually to electromagnetic booster 1000.As shown in Figure 13 B, when rotor core 1005 stator core 1004 near top of top position, now two iron cores are connected with rightabout electric current (by illustrated winding method, winding is identical, current opposite in direction), magnetic direction that stator core 1004 and rotor core 1005 produces relative (for example: the N level of stator core to the center of circle and the N level of rotor core outside circle, or the N level of stator core outside circle and the N level of rotor core to the center of circle), make to have repulsion between interior outer iron core, stator core 1004 will rotate by drive rotor iron core 1005.When rotor portion forwards certain angle to (in the embodiment of 2 iron cores, approach 180 degree) after, same rotor core 1005 is when near next stator core 1004, repulsion between homopolarity will become the resistance that rotor portion rotates, now need the power-off simultaneously of the coil of stationary part and rotor portion, due to power-off, magnetic field between rotor core 1005 and stator core 1004 will disappear, booster flywheel 1008 is because inertia continues motion, when same rotor core 1005 is crossed another stator core 1004, continuation is to coil electricity, now between rotor core 1005 and stator core 1004, the repulsion between existing homopolarity can be actuated again rotor portion and is rotated further, under electromagnetic force, rotate so again and again, the power-assisted object that realization is rotated bent axle.
From above-mentioned analysis, want to make electromagnetic booster 1000 to play reliable power-assisted effect, key is the opportunity of break-make stream.In the present invention, the realization of coil 1006,1003 correct electric current of make-and-break is to have adopted angular displacement sensor 1010 and electronic control unit ECO29.As shown in Figure 13 C, on bent axle elongated end 371, be provided with angular displacement sensor 1010, angular displacement sensor 1010 is potentiometer type or Hall-type or photoelectric type or conductive plastics formula or condenser type or induction type angle displacement sensor, and it detects the angle that crankshaft rotating produces.At initial position, i.e. position as shown in Figure 13 B, top stator iron core 1004 and upper rotor part iron core 1005 substantially on same straight line (because the inclination of stator core 1004 is installed, in fact there is a less angle), take this position as reference basis, the angle that upper rotor part iron core 1005 clockwise rotates is counted θ, at initial position θ, is 0.When upper rotor part iron core 1005 clockwise rotates, angular displacement sensor 1010 is to a signal that angular displacement increases gradually of electronic control unit ECO 29 outputs, electronic control unit ECO 29 connects power supply (the not output in the drawings of electromagnetic booster 1000, it can be any power supply that secondary battery unit also can be to provide direct current), now, top stator iron core 1004 and the identical electromagnetic pole of upper rotor iron core 1005 while polarization, top stator iron core 1004 repels upper rotor iron core 1005, make upper rotor iron core 1005 accelerate to clockwise rotate, and turn over certain angle.Because the motion that the repulsive force of electromagnetism produces is identical with the direction of motion of rotor core 1005, thereby produce power-assisted and rotate.After upper rotor iron core 1005 turns over certain angle δ, angular displacement sensor 1010 is sent out a signal again to electronic control unit ECO29, makes coil 1005 and 1003 power-off, and rotor portion is because inertia is rotated further.The angle θ turning over when upper rotor iron core 1005 is that 360/2=180 is when spend, angular displacement sensor 1010 is given 29 1 signals of electronic control unit ECO again, electronic control unit ECO 29 connects the power supply of electromagnetic booster 1000, now, upper rotor iron core 1005 moves to lower position (being set to 180 degree with start bit), this rotor core 1005 and bottom stator iron core 1004 electromagnetic pole that polarization is identical simultaneously, bottom stator iron core 1004 repels rotor core 1005, make rotor core 1005 accelerate to clockwise rotate, and turn over certain angle.Because the motion that the repulsive force of electromagnetism produces is identical with the direction of motion of rotor core 1005, thereby produce power-assisted and rotate.Because stator core 1004 is identical with the number of rotor core 1005, and even equally spaced distribution, thereby said process can loop, and bent axle 56 rotates under the effect of electromagnetic force, thereby has realized the object of electromagnetism power-assisted.
The setting of angle δ can be decided according to the actual requirements, because the power-assisted effect of electromagnetic booster is the repulsive interaction relying between like pole, thereby the magnetic pole of same magnetic presents after the deviation of certain angle, repulsive interaction effect will be weak a lot, in addition, the consideration based on energy-conservation, can not make the electromagnetic booster of power-assisted effect switch on for a long time, therefore δ should select less angle, such as being the angle that 10 degree, 12 degree, 15 degree etc. are less than 30 degree.
It should be noted that, when narration electromagnetic booster operation principle of the present invention, suppose that orientation is as shown in Figure 13 B positive clockwise, those skilled in the art also can set anticlockwise crank angle, if set counterclockwise as just, the oblique angle of the installation site of stator core 1004 as shown in Figure 13 B should be reverse.
In addition, when electromagnetic booster is in running order, the size of electric current in the Signal Regulation electromagnetic booster 1000 that electronic control unit ECO 29 also can transmit according to velocity transducer 24, its regulative mode is: when engine 1 slowly runs, the magnitude of current of supplying with electromagnetic booster 1000 is maximum; Raising along with engine speed, electronic control unit ECO 29 just reduces the electric current in electromagnetic booster gradually, to guarantee that engine has stable moment output when slowly running, and when high speed rotating, promote the high speed rotating characteristic of engine, accelerate the process of intake and exhaust, thereby when improving maximum engine speed, improve the efficiency of engine.Equally, when electromagnetic booster is in running order, the size of electric current in the Signal Regulation electromagnetic booster 1000 that electronic control unit ECO 29 also can transmit according to door oil potentiometer 242, its regulative mode is: when throttle is large, the magnitude of current of supplying with electromagnetic booster 1000 is maximum; Along with the minimizing of throttle, electronic control unit ECO 29 just reduces the electric current in electromagnetic booster gradually.
