Description
One, technical field that the present invention belongs to:
1, electronic-controlled interfering frequency generator is used to prevent the generation of the shake line of triangle piston circulating engine cylinder body, improves reliability, durability and the life-span of triangle piston circulating engine.
2, store hot precombustion chamber, be used for the pluralities of fuel of triangle piston circulating engine, improve the business efficiency of fuel based on combustion diesel fuel; Reduce and do not fire of the pollution of waste gas residue environment.
Two, invention is understood, is quoted as proof reflection relevant technologies file:
Triangle piston circulating engine comes out to come as a kind of novel thermal machine simple in structure, a large amount of development works have been done both at home and abroad, obtained suitable effect, but also had following main difficult technical not solve, hindered triangle piston circulating engine and striven unexpectedly mutually with reciprocating engine.
1, triangle piston rotates the cylinder body shake line that starts;
When triangle piston circulating engine carried out thermodynamic cycle, the rotation of triangle piston was moved the firing chamber on cylinder body, the part of cylinder body, and the explosive impact load effect of being moved makes the deformation of cylinder body generation asymmetry.The residing physical condition in each position of cylinder body is quite complicated, the uneven internal stress that is produced, and the strain, the degree of displacement that cause each position of cylinder body to be taken place are all different; Restoring force makes cylinder body produce complicated elastic vibration, and vibration frequency and energy that each position of cylinder body of vibration is produced are all unequal.
When the natural frequency of varieties of engine thermodynamic cycles frequency near cylinder body, cylinder body just resonates.Pressure in the firing chamber is big more; The cylinder body displacement is just big more, and this displacement is an amplitude.Because of the energy of ripple with amplitude quadratic sum frequency square and medium density be directly proportional.
When apex seal slides on cylinder body, apex seal is subjected to the effect of instigating continuously of vibration wave, the radially close resonance of making same frequency of following cylinder body, this vibration frequency are between 12-17KC, and the time has been grown and wear into the shake line that density does not wait on cylinder body.Under the certain situation of the size of firing pressure, cylinder body and apex seal, each material all has the flexural rigidity of oneself; According to the distortion of materials vibration equation, the natural frequency of vibration of various materials is directly proportional with the flexural rigidity square root, is inversely proportional to the mass square root.
By wave theory, the material of cylinder body and apex seal mates mutually, is exactly their apolegamys of natural frequency separately.According to the composition principle of ripple, the displacement on any point is exactly the algebraic sum of each ripple in this some displacement that produces.
When cylinder body and apex seal coupling; The apex seal that cylinder body and firing chamber are two, vibrated as natural frequency by the impact of high-pressure gas, the energy offset of the apex seal natural vibration that the firing chamber is two cylinder body instigate energy, in the contact position of apex seal and cylinder body, formed the local region of stability of moving with apex seal.
Cylinder body is with firing chamber two apex seal force way difference, combustion gas is more much bigger than air damping again, therefore the rate of decay of apex seal vibration is faster than the rate of decay of cylinder body vibration, during the capable nearly cold arc of the front side apex seal of firing chamber district, decay does not produce natural vibration gradually, and at this moment cylinder body is still vibrating; The apex seal that slides to cold arc district does not have the energy of instigating of energy offset cylinder body gradually, instead is subjected under the driving force effect of cylinder body at cylinder body, produces the resonance wearing and tearing.
Begin eccentric rotary in 180 ° of time from the burning maximum pressure, have two apex seals to produce the energy of instigating of natural vibration energy offset cylinder bodies in hot arc district, but do not have the natural vibration energy in one in cold arc district and remove to offset the cylinder body energy; Eccentric shaft rotates in 180 ° of times three apex seals again and does not produce the natural vibration energy and remove to offset cylinder body and instigate energy, and periodically if things go on like this, it is lighter just to occur hot arc district shake line on the cylinder body; The more serious phenomenon of cold arc district shake line.
When the material selection of cylinder body and apex seal improper, according to the composition principle of ripple, the natural vibration ripple of cylinder body natural vibration ripple and apex seal is superimposed when sliding, and synthesis wave is greater than incoming wave and reflected wave, form the resonance wearing and tearing, so within a short period of time occurs the shake line.
See two examples now again:
During Tangshan Earthquake in 1976, have row to leave for the train of Shenyang direction from Beijing, when train vibration influence arrived Tangshan Area, the driver found to emerge blue flame on the ground, then train is felt shaking, the driver just takes out of immediately and forces to move, and changes weak braking into, after train stops well, railway bridge in train the place ahead collapses, rail at the train rear has shaken and has turned over, and be a slice ruins around train, yet this row train is safe and sound.
Train is when high-speed operation, each component on the train are all being done the vibration of natural frequency, be subjected to forcing the energy of moving after vibration to be strengthened suddenly, at this moment the natural vibration wave interference of train seismic waves, zone at train running forms the region of stability of moving with train, has reached shockproof effect.
" Reference News " nineteen eighty-two also reported Soviet Union get the seismologist in building by dress interfering frequency generator, produce seismic wave intrusively.Reach shockproof effect.
2, triangle piston circulating engine is low to the business efficiency of fuel, and exhaust is to the pollution of environment; So far the triangle piston circulating engine that does not also have burning diesel oil.
The firing chamber is the heart of motor, and the burning of its tissue directly influences the performance of motor and business efficiency.
Triangle piston circulating engine can not design higher compression ratio owing to be subjected to the influence of shape ginseng event, and higher compression finishing temperature is provided; Compress at the end the firing chamber be one long and narrow square, longitudinal separation is longer.Eccentric shaft is crossed atdc, because the squeezing action of the rear side of triangle piston, makes the flame can not reverse backward propagation, and under the pressure of gas of combustion, the mixed gas of firing chamber rear side is in low temperature, the anoxic deflagration; In the obvious burning phase, this is the impossible burning of fuel heat release partly, and the afterburning phase is extended to after the exhaust, and delivery temperature is up to more than 900 ℃.As the KKM612 gasoline triangle piston circulating engine of West Germany, at 4000 rev/mins, the thermal equilibrium ratio of full throttle; Useful horsepower 28%, water and machine oil 22%, exhaust 38%, do not fire waste gas residue 12%, i.e. exhaust accounts for 50% of total amount of heat; Do not fire waste gas environment is polluted, Curtiss-Wright Corp has adopted the smoke evacuation reactor of no income to be installed in exhaust ports, and the temperature of reactor is up to 1100 ℃, and a large amount of fuel are wasted.

Three, Fa Ming purpose:
1, the principle design that electronic-controlled interfering frequency generator is the phase mutual interference that utilizes ripple, energy is cancelled out each other; Triangle piston circulating engine in the running, electronic-controlled interfering frequency generator is according to the instantaneous position that is in cylinder body of apex seal, the concrete condition of this position vibration of cylinder body, the energy that produces best interference frequency removes to offset the energy of instigating of cylinder body.Make the contact position of apex seal and cylinder body form the region of stability of moving, prevent the generation of cylinder body shake line like this with apex seal.
2, the hot precombustion chamber of storage is to utilize the storage of heat, the pluralities of fuel mixed gas based on diesel oil is carried out convection heating and the width of cloth penetrate that heating principle designs; Motor is when thermodynamic cycle, form the upper and lower two-layer continuous revolution air-flow of different temperatures in the firing chamber, make fuel mixture that the condition of sufficient evaporation, gasification, little mixing be arranged, quicken the obvious burning phase, shorten the afterburning phase, improve the efficient of motor and the Economy of fuel.
Four, Fa Ming content:
1, electronic-controlled interference FIT Frequency Generator is by (1) high frequency oscillator; (2) microcomputer controller; (3) interference wave transmitter three parts are formed.
High frequency oscillator and microcomputer controller are installed in the outer one of forming separately of engine block, link with the interference wave transmitter in the triangle piston apex-seal groove with the conducting wire, become an integral framework.
During engine running, micro computer is measured three apex seals, the concrete condition of vibration of living on instantaneous three different positions on cylinder body, again according to each apex seal at this moment between in the energy size of the natural frequency of vibration that possessed or the concrete condition that has or does not have, the instruction high frequency oscillator produces required best high frequency current to each disturbing wave generator respectively; Various high frequency currents are transferred to interference wave transmitter in each apex-seal groove respectively by lead, convert the energy that cylinder body that mechanical wave goes to offset this place is instigated ripple to by interference wave transmitter.Making all has around the line contact area of each apex seal and cylinder body one to move stable zonule with apex seal.
Therefore the complicated come what may vibration of cylinder body, the apex seal that slides on cylinder body remains at the region of stability and normally slides, and has prevented the cylinder body shake line that produces because of the wearing and tearing of periodically resonating.
Interference wave transmitter is actually an electromechanical vibrational energy transducer, and its kind is a lot, and it is main selecting piezoelectric material for use from the reality of bearing high temperature, high pressure.
Interference wave transmitter is installed in each apex-seal groove of triangle piston, and apex seal behind and apex seal form a whole, and are contained in above the spring.The terminal of interference wave transmitter and the terminal on the triangle piston are connected, the outer high frequency of interference wave transmitter and machine are shaken and the micro computer modulator is unified into an integral body.
The principle that lead road on the triangle piston and extraneous electric line joint are the internal gears that utilize triangle piston to turn round mutually with the end cap fixed gear, the conducting slip ring of design; Conducting slip ring is arranged in an end that does not have gear.The entad face of the conducting slip ring on the triangle piston is done conductive contact surfaces in echelon; No. three conductive hoops conductive hoop that forms a whole is embedded on the triangle piston, and each road lead ring all has concealed wire and interference wave transmitter to be connected.Fixedly conductive hoop also is three the tunnel, and fixedly the centrifugal face of conductive hoop is also done trapezoidal surface of contact, and fixedly conductive hoop can move axially, and is not rotatable.With end cap on adorn thrust spring, fixedly conductive hoop remains tight the contact with the triangle piston conducting slip ring under the effect of spring force, makes conduction normal.
The disturbing wave that interference wave transmitter sends is that the local zonule of cylinder body is disturbed, and its energy size sees that cylinder body decides the instigating the energy size of diaphragm seal radially; Needn't the total energy of whole cylinder body vibration be disturbed.
2, the hot precombustion chamber of storage is mounted in a kind of auxiliary combustion chamber of the every limit of triangle piston in recessed and is made little fishing boat of outer appearance by heat-resistant material; In the hot precombustion chamber of storage, there are two diversion bell mouths the front portion, bell-mouthed root communicates with wheat biousse conduit, and though air-flow from that diversion bell mouth inflow wheat biousse conduit when flow out the air outlet, can both play suction effect mutually;
Store hot precombustion chamber by when dress, have only link contact segment and triangle piston near, remaining extremely big portion all leave the heat conducting insulated room slot of obstruction; Can remain on the steady temperature more than 600 ℃ during engine operation.
Rising and employing gasoline is fuel, and air flows to secondary suction tude from turbocharger, forms oily mixed gas in secondary suction tude.Mixed gas flows into cylinder through turning on valve in the tangential admission mouth, in the hot precombustion chamber of storage was backflowed at the apex seal place before flowing to along casing wall, two-layer revolution air-flow about the shape burnt in the firing chamber.Because do not reach higher temperature in the firing chamber, fuel also has the phenomenon of incomplete combustion during starting, and exhaust gas recovery is fired again.
The temperature of the hot precombustion chambers of storage such as starting back reaches 600 ℃, closes secondary suction tude when above, opens main air intake, and diesel fuel injection pump is started working.
Fresh air flows to the whirlwind maker from turbocharger, flows into cylinder from the tangential admission mouth.Because the speed of inlet stream is greater than the maximum sliding speed of apex seal, air inlet flow to the apex seal place just backflow the storage hot precombustion chamber in, in long Mobius pipe road, do reversing of 360 ° and 180 °, increase air-flow and the chance of storing hot precombustion chamber convection heat exchange and radiation heat exchange, improve the compression finishing temperature.
The rotation of triangle piston, when first diversion bell mouth faces toward oil nozzle, oil nozzle begins to spray fuel in the hot precombustion chamber of storage, along with changeing, triangle piston rotation fuel sprays in second diversion bell mouth, be injected in the hot precombustion chamber of storage more than 600 ℃, do reversing of 360 ° and 180 °, improved the efficient of fuel mixture with hot precombustion chamber convection heat exchange of storage and radiation heat exchange; The evaporation gasification of fuel oil particle and the diffusion of little mixed gas have been quickened.
From storing the mixed airflow that flow out in heat combustion outlet port, chamber, through the side face of triangle piston and the hot precombustion chamber of storage side flow forward, around spark plug, drop on fuel fume on the diversion bell mouth wall at water conservancy diversion and meet fashionablely with splashing down, spark plug begins igniting.
Flame group forms the back main portion and continues expansion forward; Another part under the absorption of spray in the hot precombustion chamber pipeline of storage, to rear side expansion burning.
At this moment eccentric shaft has just been crossed top dead center, and the mixed airflow of firing chamber is to do revolution to flow under the effect of inertial force and spray momentum, and flame propagates into whole firing chamber soon, has accelerated the burning of fuel in the obvious burning phase, shortens the afterburning phase.Solved the triangle piston circulating engine past flame problem of reverse propagation backward.
The use of storing hot precombustion chamber has reduced scattering of heat; Improve circulating temperature, increased the useful horsepower of wankel engine and the Economy of burning.
