Description
Technical field
The present invention relates to a kind of two stroke engine assembly, in particular to a kind of, using the two-stroke air power engine assembly of pressurized air as the employing electromagnetic booster of power source.
Background technique
Motor is widely used in all trades and professions, Modern Traffic means of transportation such as automobile, steamer etc. in, general employing usingd the piston internal-combustion engine of fuel oil as power source.This employing fuel oil as the motor 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 matters and befouling environment, because the fuel oil using is to refine and obtain from oil, the day by day in short supply of petroleum resources makes the development of fuel engine and utilization be subject to increasing restriction on the other hand.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.
Substitute fuel automobile, as rock gas (CNG, LNG) automobile, alcohols automobile, dimethyl ether automobile etc. still have exhaust emission and thermal effect, some fuel is also toxic, and difficulty is controlled in some fuel combustion, thereby still has in actual use many difficulties and challenge.
Non-pollution discharge in electric automobile during traveling, noise is low, energy conversion efficiency is high, but battery-driven electric vehicle is limited by on-vehicle battery, in the degree that is difficult to for the moment aspect specific power, cycle life, charge-discharge performance, cost and Security reach practical, meanwhile, there is serious secondary pollution in battery itself.Hybrid-power electric vehicle has advantages of cell electric vehicle and internal-combustion engines vehicle, but still has discharge and pollution problem, and due to the existence of two cover power plant, and it drives and the control system complex that becomes, thereby has hindered practical application and development.
Fuel cell is placed high hopes by people, can realize the zero-emission of power output, and energy conversion rate is high, but the manufacture cost of fuel cell is high, the safety storing of hydrogen, preparation and fillingly have many problems, and this has just restricted development and the use of this power source greatly.Solar cell still needs to reduce battery volume and improves photoelectric transformation efficiency, thereby is specifically applied on transport facility and still needs to make a breakthrough.
In sum, the equal Shortcomings part of hybrid power source that above-mentioned various new power source 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 the Designer Guy Negre for French MDI company of compressed-air power engine, it has proposed the concept of air-powered motor, attempt to solve the problem of utilizing of " zero-emission " 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 air-powered motor is worked, is converted to other forms of mechanical energy by the pressure energy of pressurized air storage.The visible FR2731472A1 of research, US6311486B1, US20070101712A1 etc. about air-powered motor.
FR2731472A1 discloses a kind of motor that can work under fuel supply and two kinds of patterns of pressurized air supply, on expressway, adopt conventional fuel as gasoline or diesel oil, in low speed particularly urban district and suburbs, pressurized air (or other any on-contaminated pressurized gass) is injected to firing chamber.Although this motor 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 motor has adopted three independently chambers: air-breathing-pressing chamber, expansion exhaust chamber and constant volume firing chamber, and air-breathing-pressing chamber is connected to constant volume firing chamber by valve, constant volume firing chamber is connected to expansion exhaust chamber by valve.One of problem of this motor is that time of experiencing from air-breathing-pressing chamber to expansion exhaust chamber of pressurized gas is longer, the power source gas time that obtains driven plunger acting is longer, simultaneously, the pressurized gas of discharging from expansion exhaust chamber fail to be used, and this has just limited working efficiency and the single aeration continuous working period of this class motor.
More domestic researchers and unit are also studied air-powered motor, but most concentrating in the feasibility and working 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 air-powered motor, 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 allocation problem of high pressure air, from the commercialization process of air-powered motor, have got long long way to go.
The application's claimant 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 motor comprises gas holder, air distributor, motor, clutch, clutch, automatic transmission, differential mechanism and is placed in the turbo dynamo in exhaust chamber.This motor utilizes compressed air to do work and does not use any fuel, therefore there is no toxic emission, has realized " zero-emission ".But this motor 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 high-pressure air of power source can be in entering cylinder time, and then discharge, the stroke of air-powered motor is actual is air inlet-expansion stroke and discharge stroke.Obviously, the disclosed this four-stroke air-powered motor of patent documentation CN101413403 A has been wasted effective expansion stroke greatly, has limited the efficiency of motor, and this has just reduced air-powered motor 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 center by flywheel via the inertia of Crankshaft motion, thereby the pressurized air in work chamber is discharged.Yet, because expanding in active chamber, pressurized air promotes still there is larger pressure after piston acting, 3MPa for example, piston is only discharged the pressurized 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 active 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, sensor, control module and power supply, signal that control module provides according to sensor 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 electromagnetic coil, 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 element.
Based on the problems referred to above, the present invention aims to provide a kind of electromagnetism power-assisted two-stroke air power engine assembly, is intended to solve effective acting problem of compression engine, thereby realizes novel air power engine economic, efficient, zero-emission.

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 character represents identical or corresponding parts and feature.
Before describing the specific embodiment of the present invention in detail, first the energy with regard to air-powered motor carries out theory analysis.
The acting process of air-powered motor is fairly simple, the process of only having pressurized air to expand and do work.As shown in Figure 12 A, Fig. 1-5 are pressurized air isothermal expansion process, and 1-6 is pressurized air adiabatic expansion.It can not be isothermal process completely that pressurized air does work in motor, conventionally between isothermal process and adiabatic process, in order to improve compressed-air actuated capacity usage ratio, can adopt multistage adiabatic process to be similar to isothermal process, or adopt the appearance endothermic process such as multistage to be similar to isothermal 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 motor as isothermal expansion process, so curve 1-5 and coordinate figure V
1, V
2between the energy of the cartographic represenation of area pressurized 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 pressurized air storage that comprises discharge the gas expansion merit that can change.
The inflation pressure of supposing high pressure gas holder is p
1, gas storage volume is V
1perfect 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 motor 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 operating 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 gas holder is double centner, and corresponding specific energy is about 75Wh/kg.The on-vehicle battery of comparing, for example lead-acid battery and nicad battery, 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.
Pressurized air has two kinds of acting forms in motor, i.e. isothermal expansion process and adiabatic expansion, below with both features of design parameter calculation specifications.
Choose original state 1 (30MPa, 300K), end of a period state 2 (0.1MPa, 300K), the expansion work of asking unit mass pressurized air to do in isothermal process and adiabatic process respectively.Isothermal expansion process unit mass gas institute work is W=491kJ/kg, and adiabatic expansion unit mass pressurized air institute work is W '=242.3kJ/kg.From theory, calculated, the expansion work of isothermal 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 motor 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 air-powered motor kinds of power distribution patterns below.
Under parallel way, the pressurized gas of equivalent is input to each cylinder expansion acting simultaneously.If original state 1 (30MPa, 300K), end of a period state 2 (0.1MPa, 300K), pressurized air carries out isothermal expansion in cylinder, and isothermal is similar to rate η=80%, cylinder number is 4 cylinders, and the pressurized air that enters motor 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 head pressure of pressurized 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 serial fashion, by pressurized 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 pressurized 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 size requirement of motor, can have a strong impact on the integral layout of the equipment that uses air-powered motor.
From upper analysis, air-powered motor is different from traditional fuel engine 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, pressurized 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 pressurized air utilization efficiency, and increasing pressure pan capacity and inflation pressure is to improve the Main Means of once inflating continuous working period.At tank, hold, inflation 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, pressurized air distribution are the problems that needs further investigation.
Through above-mentioned theory analysis, the application's claimant 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, claimant adopts tail gas recycling loop, will be described in detail concrete mode of the present invention below.

Detailed structure and the working principle of electromagnetic booster 1000 are described now.The different embodiments 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 iron core fixed tray 1002, stator iron core 1004 and stator iron core coil 1003.Rotor portion is comprised of rotor iron core fixed tray 1007, booster flywheel 1008, rotor iron core 1005 and rotor iron 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 iron core fixed tray 1002 of stationary part is fixedly connected on booster shell 1001, and stator iron core 1004 is plugged on stator iron core fixed tray 1002, is wound with stator iron core coil 1003 on it.
Rotor iron core fixed tray 1007 is by interference fit or be threaded and be fixedly mounted on booster flywheel 1008, to rotate with booster flywheel 1008.On rotor iron core fixed tray 1007, be plugged with rotor iron core 1005, on rotor iron core, be wound with rotor iron 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 extending 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 iron core fixed tray 1002, such as being is threaded or interference fit, be that stationary part and booster shell 1001 do not exist kinematic relation each other, booster shell 1001 forms a fixed connection by the polygonal lid 313 of the fastening pieces such as the bolt through shell mounting hole 1011 or screw and front gear box system 43, thereby stator is fixedly mounted on motor 1.And rotor portion rotates with bent axle 56 with being fixedly connected with of bent axle extending 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 iron cores 1006 that become 180 degree to place become the stator iron 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 iron core coil 1006 of rotor portion and the stator iron core coil 1003 of stationary part are produced promotes bent axle 56 rotations, can suitably stator iron core 1004 suitably be tilted to install, such as stator iron core 1004 can be become to the acute angle angle inclination installation of 5 ° to 30 ° with respect to the elongation line of rotor iron 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 iron core 1004 is 5 °, 8 °, 12 °, 15 °, 20 ° with respect to the angle of inclination of rotor iron core.For the magnetic field that utilizes better coil 1006 and 1003 to produce, reduce iron loss, stator iron core 1004 is built up by silicon steel plate, and rotor iron core 1005 is made or also by silicon steel plate, is built up by whole steel.
Further describe now the working 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 iron core 1005 stator iron 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 iron core 1004 and rotor iron core 1005 produces relative (for example: the N level of stator iron core to the center of circle and the N level of rotor iron core outside circle, or the N level of stator iron core outside circle and the N level of rotor iron core to the center of circle), make to have repulsion between interior outer iron core, stator iron core 1004 will rotate by drive rotor iron core 1005.When rotor portion forwards several angle to (in the embodiment of 2 iron cores, approach 180 degree) after, same rotor iron core 1005 is when near next stator iron 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 iron core 1005 and stator iron core 1004 will disappear, booster flywheel 1008 is because inertia continues motion, when same rotor iron core 1005 is crossed another stator iron core 1004, continuation is to coil electricity, now between rotor iron core 1005 and stator iron 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 extending end 371, be provided with angular displacement sensor 1010, angular displacement sensor 1010 is potentiometer type or Hall-type or photoelectric or conductive plastic 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 iron 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 battery unit also can be to provide direct current (d.c.)), 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 several angle.Because the motion that the repulsive force of electromagnetism produces is identical with the moving direction of rotor iron core 1005, thereby produce power-assisted and rotate.After upper rotor iron core 1005 turns over several 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 iron core 1005 and bottom stator iron core 1004 electromagnetic pole that polarization is identical simultaneously, bottom stator iron core 1004 repels rotor iron core 1005, make rotor iron core 1005 accelerate to clockwise rotate, and turn over several angle.Because the motion that the repulsive force of electromagnetism produces is identical with the moving direction of rotor iron core 1005, thereby produce power-assisted and rotate.Because stator iron core 1004 is identical with the number of rotor iron 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 several 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 working 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 mounting point of stator iron 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 motor 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 motor has stable moment output when slowly running, and when high speed rotating, promote the high speed rotating characteristic of motor, accelerate the process of intake and exhaust, thereby when improving maximum engine speed, improve the efficiency of motor.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.
