Technical field
The utility model relates to the device that a kind of motor is used, in particular to a kind of controller system that is used for air-powered motor.
Background technique
Motor is widely used in all trades and professions, and transport facility generally adopts with the piston internal-combustion engine of fuel oil as power source such as in automobile, the steamer etc. in modern times.This employing fuel oil is insufficient because of oil inflame on the one hand as the motor of power source; Contain a large amount of harmful matters and befouling environment in the feasible gas of discharging; Because of the fuel oil that uses is from oil, to refine to obtain, the in short supply day by day of petroleum resources makes the development of fuel engine and utilization receive increasing restriction on the other hand.Therefore develop new, clean, free of contamination alternative energy source, perhaps reduce fuel consume as much as possible, reduce discharging and become urgent problem in the motor development.For this reason, various countries have experienced the road of complicated and hard exploration, have researched and developed multiple power source, such as substitute fuel, motorized motions, fuel cell and solar cell etc.
The substitute fuel automobile; Like rock gas (CNG, LNG) automobile, alcohols automobile, dimethyl ether automobile etc. exhaust emission and thermal effect are arranged still; Some fuel is also toxic, some fuel combustion control difficulty, thereby still have many difficulties and challenge in actual use.
Non-pollution discharge in the 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 the Security reach practical; Simultaneously, there is serious secondary pollution in battery itself.Hybrid-power electric vehicle has the advantage of cell electric vehicle and internal-combustion engines vehicle, but still has discharging and pollution problem, and because the existence of two cover power plant, it drives and control system becomes unusual complicated, 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, and the safe storage of hydrogen, preparation and can all have many problems, and this has just restricted the development and the use of this power source greatly.Solar cell still need reduce the battery volume and improve photoelectric transformation efficiency, thereby specifically is applied on the transport facility and still need makes a breakthrough.
In sum, all there is deficiency in the hybrid power source that above-mentioned various new power source or their constitute, thereby, pressing for a kind of not have pollution, nexhaustible novel energy, this requirement has just in time been satisfied in the compressed-air power source.
Study the Designer Guy Negre for French MDI company of compressed-air power engine the earliest; It has proposed the notion of compressed air engine; Attempt to solve the problem of utilizing of " zero-emission " and the energy capable of circulation; From then on opened the new page of engine research, and released the pure aerodynamic economical family expenses bridge car of first item in 2002.The pressurized air compressor uses high pressure air as power source, and air when compressed air engine is worked, can convert the pressurized air stored pressure into other forms of mechanical energy as medium.About the visible FR2731472A1 of the research of compressed air engine, US6311486B1, US20070101712A1 etc.
FR2731472A1 discloses a kind of motor that can under supply of fuel and two kinds of patterns of pressurized air supply, work; On expressway, adopt conventional fuel such as gasoline or diesel oil; In low speed particularly urban district and suburbs, pressurized air (or other any on-contaminated pressurized gass) is injected the firing chamber.Though this motor has partly reduced fuel consumption, owing to still adopted fuel oil mode of operation, emission problem still to fail 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 the constant volume firing chamber through valve, and the constant volume firing chamber is connected to the expansion exhaust chamber through valve.One of problem of this motor is that time of experiencing from air-breathing-pressing chamber to the expansion exhaust chamber of pressurized gas is longer; The power source gas time that obtains the driven plunger acting is longer; Simultaneously; Fail to obtain to use from the pressurized gas that the expansion exhaust chamber is discharged, this has just limited this type efficiency of engine and single aeration continuous working period.

Embodiment
Below illustrative in nature on only be exemplary and be not in order to limit the disclosure, application or purposes.Should be understood that in whole accompanying drawings, corresponding reference character is represented identical or corresponding components and characteristic.
Before the embodiment of describing the utility model in detail, the energy with regard to compressed air engine carries out theory analysis earlier.
The acting process of compressed air engine is fairly simple, the process of having only pressurized air to expand and do work.Shown in Figure 12 A, Fig. 1-5 is a pressurized air isothermal expansion process, and 1-6 is a pressurized air adiabatic expansion process.It can not be isothermal process completely that pressurized air does work in motor; Usually between isothermal process and adiabatic process; Can adopt multistage adiabatic process to be similar to isothermal process in order to improve compressed-air actuated capacity usage ratio, perhaps adopt 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 among Figure 12 A, and 1-2 and 3-4 accomplish in first cylinder and second cylinder.Working medium through the acting of the adiabatic expansion of the first order after, carry out isobaric heat absorption 2-3 through a heat exchanger again, get back to initial temperature after, get into the acting of expanding of second cylinder again.Theoretically, can regard the acting process of motor as the isothermal expansion process approx, so curve 1-5 and coordinate figure V 1, V 2Between the energy of the cartographic represenation of area pressurized air storage that comprised discharge the gas expansion work that can change.And in Figure 12 B, curve 1,2 is represented compressed-air actuated isothermal, adiabatic expansion process respectively among the figure, and actual puffing process is between curve 1, between 2.A is a starting point among the figure, and the pressure classification point when B, C, D, E are the control of corresponding transfer pressure has endothermic process such as the appearance of grade, like 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 comprised discharge the gas expansion work that can change.
The inflation pressure of supposing high pressure gas holder is p 1, the gas storage volume is V 1Perfect gas in complete isothermal expansion to normal pressure p 2Whole expansion works that Shi Suoneng does are:
In the formula, (p 1, V 1) and (p 2, V 2) being initial, end of a period state accordingly, the end of a period state after the 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 the 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, the 300MPa air pressure is 104.553 kilograms, and the quality of supposing gas holder is a double centner, and then 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 Ni-MH battery substantially, has development prospect preferably.Along with the development of the big capacity of high pressure tank, big pressure and lightweight, compressed-air actuated specific energy also has raising significantly, even can be near sodium-sulphur battery and lithium polymer battery.
Pressurized air has two kinds of acting forms in motor, promptly isothermal expansion process and adiabatic expansion process are explained both characteristics below with concrete calculation of parameter.
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.The merit that isothermal expansion process unit mass gas is done is W=491kJ/kg, and adiabatic expansion process unit mass pressurized air institute work is W '=242.3kJ/kg.Can be known that by theoretical calculation the expansion work of isothermal process almost is 2 times of adiabatic expansion process, so the capacity usage ratio of isothermal expansion is higher than adiabatic expansion, it is desirable adopting the isothermal expansion acting in theory.But " isothermal " is to be difficult to realize in cylinder, must have a secondary hot-fluid to import motor machine wall to keep enough heats.This has just increased technical difficulty, makes engine structure complicated unusually.Further utilize angle that two kinds of power distribution patterns of compressed air engine are discussed below from compressed-air actuated energy.
Under parallel way, the pressurized gas of equivalent is input to the acting of expanding of each cylinder simultaneously.If original state 1 (30MPa; 300K); End of a period state 2 (0.1MPa; 300K); Pressurized air carries out isothermal expansion in cylinder, isothermal is similar to rate η=80%, and cylinder number is 4 cylinders; The pressurized air that gets into motor is 1 kilogram of unit mass; The total technological merit that 4 cylinder gases are done is visible for , though the 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 big volume.If the cylinder of the cylinder that adopts available engine after as isothermal expansion; Selecting compression ratio is 10, then W=198.3kJ/kg.Obviously, technological merit significantly reduces, the technological 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 present technology; Cylinder can not keep complete isothermal; And the compression ratio of cylinder can not be done too much, and 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 practical at present, effective and efficient manner.
Under serial fashion, with pressurized air adiabatic expansion acting successively in each cylinder, the discharge gas of previous stage cylinder is the initial pressure of next cylinder.Can know through theoretical calculation analysis: the series connection classification is many more, and the series connection cylinder number that promptly uses is many more, and the pressurized air institute work of unit mass is many more, and capacity usage ratio is high more, 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, and is not little to total technological work difference.The greatest problem of serial cylinders is that the volume of back one-level cylinder all is greater than the volume of cylinder of previous stage, and all will load heat exchanger so that isobaric heat absorption between the 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 compressed air engine.
Visible by last analysis, compressed air engine is different from traditional fuel engine and various electric power device, and it is feasible on principle, and the strategy of sustainable development that meets environmental protection, economizes on resources.And other forms such as that pressurized air convenient sources, energy storage mode are superior to is electric, hydraulic pressure.Compressed-air actuated power distribution form respectively has pluses and minuses, improves the pressurized air utilization efficiency, and increasing pressure pan capacity and inflation pressure is to improve the main means of once inflating continuous working period.Under the situation that jar holds, inflation pressure is confirmed relatively, compressed air energy utilization rate η is maximum running parameter.Problems such as engine structure optimization, tail 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 parallelly connected power allocation model; In order to improve the pressure of compressed air energy utilization rate and acting back discharge gas; The claimant adopts and replenishes the pressurized air loop, will the concrete mode of the utility model be described in detail below.
