Background technique
1842, English physicist Earnshow proposed maglev concept, pointed out simultaneously: depending merely on permanent magnet is
One ferromagnet cannot be held to the suspended state of free and stable in all six freedom degrees.Magnetic suspension train is to utilize
The design of " there is a natural attraction between the sexes " principle, is a kind of suction suspension system, using the levitating electromagnet being mounted on the bogie of train two sides,
The magnet in orbit with laying.Electromagnet is housed, coil is then installed in railway bottom on magnetic suspension train.After energization, ground line
The electromagnet polarity total security enclosed on the polarity of the magnetic field and train generated is held identical, and the two " identical charges repel each other " produces under magnetic fields
Raw suction floats vehicle.
The pole electromagnet N on magnetic suspension train head is installed in the pole electromagnet S on the track of former point and is attracted, together
When be mounted the further along pole electromagnet N in orbit again and repelled.When train advances, the current direction flowed in coil is just
In turn, i.e., the original pole S becomes the pole N, and the pole N becomes the pole S.Cycle alternation, train just run quickly forward.Stability is by guidance system
To control.Electromagnet is installed at magnetic suspension train bottom and the top of two sides bogie, in the top and upper arm part of " work " word rail
Lower section set reaction plate and induction steel plate respectively, the electric current for controlling electromagnet keeps electromagnet and interorbital between 1 centimetre
Gap, the attraction allowed between bogie and train are mutually balanced with train gravity, and train is floated 1 centimetre of left side using magnetic pull
The right side makes train suspension orbit.This must accurately control the electric current of electromagnet.Rail on both sides are also equipped with coil, exchange
Electricity makes coil become electromagnet.It interacts with the electromagnet on train, and train is made to advance.The electromagnet (pole N) of train head
It is leaned on the electromagnet (pole S) of former point to attract on track, while being arranged by electromagnet (pole N) further along on track
Reprimand --- the result is that one " pushing away " one " drawing ".Certain gap (generally 1-10cm) is kept with track when magnetic suspension train operation,
Therefore operational safety, steady comfortable, noiseless, may be implemented full-automatic operation.

Crankshaft-and-connecting-rod, can the direct generation of electricity by the reciprocating motion of piston.One free-piston engine linear electrical generator
Output power can arrive 10KW, it is only necessary to two such devices can drive a compact car or compact sedan reach 120 public affairs
In/hour.
It is born so far from quartastroke engine, how to improve the efficiency of engine is that Engine engineers make great efforts to grind always
The project studied carefully.Engine efficiency is mentioned, " compression ratio " just naturally becomes the leading role of discussion.All the time, " high pressure
Contracting ratio=high efficiency, high power " has become creed constant in internal combustion engine.By air inlet, compression, expansion, exhaust four
The quartastroke engine that a stroke cycle is constituted is that Otto lasts 14 years in research and development in 1876 successfully, the engine principles, quilt
Referred to as Otto cycle.And it can wherein improve the most critical ring of the efficiency of internal combustion engine --- compression stroke becomes machine from principle
The process of tool had once perplexed Otto ten as long as the several years.
1940, miller had developed a kind of not reciprocity expansion/compression than engine, was manufactured using distribution opportunity this
Effect.Its settling mode are as follows: at the end of intake stroke, postpone the closing of valve, this just goes out the gaseous mixture of sucking again " spitting "
A part is gone, valve is turned off, starts compression stroke.It is this cleverly to design, the intake efficiency of engine is not only improved,
So that the expansion ratio of engine is higher than compression ratio, engine efficiency is effectively improved, the working principle of this engine is claimed
For Miller cycle.1821, the discovery of roentgen Seebeck, different metallic conductor (or semiconductor) have it is different from
By electron density (or carrier density), when two different metallic conductors contact with each other, electronics on the contact surface will
It is spread from high concentration to low concentration.And the diffusion rate of electronics is directly proportional to the temperature of contact zone, as long as so maintaining two metals
Between the temperature difference, electronics can be made to continue to spread, form stable voltage in the another two endpoint of two blocks of metals.Here it is " Sai Bei
Gram effect ".

It should be noted that this magnetic suspension free piston type 6-stroke IC engine provided by the invention, may be implemented rice
It strangles circulation and Alto recycles Two-way Cycle, save fuel.
Alto circulation is also known as four-stroke cycle, one kind of internal combustion engine thermal force circulation, for the ideal thermodynamic cycle of constant volume heating.
A French engineer in 1862 proposes four-stroke cycle principle first, and German engineer Nicholas Otto utilizes within 1876
This principle has invented engine, because this engine has the excellent performances such as stability of rotation, noise be small, very to industrial impact
Greatly, therefore this circulation is named as Otto cycle.
The a cycle of Otto cycle is by breathing process, compression process, expansion work process and exhaust process this four
Stroke is constituted, and piston moves downward first makes the mixture of fuel and air enter cylinder by one or more valve, is closed
Close inlet valve, piston upwards compressed mixed gas, then by spark ignitor gaseous mixture when close to compression stroke vertex
Body, combustion air explode caused by thrust force that piston moves downward, complete expansion stroke, finally lead to burnt gas
Cross exhaust valve discharge cylinder.As shown from the above technical solution, in this magnetic suspension free piston type six-stroke provided by the invention
Alto circulation may be implemented in combustion engine.
It is understood that the acting of engine, mixture combustion pushes piston downlink after igniting, but arrived lower dead center with
Afterwards, also release finishes the energy of gaseous mixture far away in fact.According to Otto cycle, exhaust valve must be opened at this time and is vented, it is remaining
Energy is by emitting in vain.It not only wastes, but also not environmentally.If expansion ratio becomes larger? piston can run one down again
Section arrives lower dead center again, can more effectively utilize the dump energy of gaseous mixture in this way, efficiency is also naturally higher, therefore the present invention mentions
The technical solution of confession joined Miller cycle on the basis of Alto recycles again.
Gasoline engine work be all produced by breaking out stroke, if that this outburst stroke can be continued for, piston
It is slow by the time of lower dead center, can function be generated using the pressure of combustion gas expansion as far as possible.There is one to be known as expanding
The value of ratio is exactly used to define the ratio of volume and combustion chamber volume after burning gases expansion.Miller cycle engine is exactly a kind of
The big engine of expansion ratio, the comparison for representing burning gases expansion is more, does work bigger.
But the problem of expansion ratio is big, also represents the increase of compression ratio, and compression ratio one improves, pinking, is difficult to avoid, rice
The gas sucked in when strangling circulation air inlet, and go out to having put stealthily.When compression stroke is incipient, inlet valve is in fact
It is not turned off, so some gaseous mixture has just been returned in air inlet pipe, (technical solution provided by the invention is in induction stroke
In, driving trip piston is moved to the volume that the first left side extreme position reduces cylinder-variable, that is, in Miller cycle
The gas sucked in when by air inlet is gone out to having put again, to achieve the effect that Miller cycle).At this moment, recycle just has originally
The high compression ratio of 10:1 carry out expansion stroke, just produce so big power.Because really compressed when compression travel
For gaseous mixture in fact without so more, actual compression ratio does not have expansion ratio so high, has effectively avoided pinking whereby yet
Problem.
It is understood that internal combustion engine when running Miller cycle power compared with Otto cycle when decrease but fuel economy
Property increases.
