Background technique

Mainly contain in the at present known various straight moving electricity generating plans 1. by cylinder joint work lever actuated, this class working method has been lacked bent axle, but has increased mechanism such as lever, does not have remarkable advantages; 2. newly-increased airtight cylinder, the driving of pneumatically, this class method of work will guarantee the sealing of newly-increased cylinder, if can not guarantee fully, also will increase air compensating system, does not realize substantially; 3. rely on current drives, should this type systematic fairly simple, control also more conveniently, but conversion (four stroke engine) between 8 electric energy and the mechanical energy is arranged in each acting circulation, increased electrical loss, reality is difficult to obtain the effect of raising the efficiency; 4. the small generator (2～3 inch) of two-stroke with spring vibration realization reciprocating motion of the pistons proposed in the US6349683 invention; This class generator has utilized the spring driving in compression stroke, can realize that two journey motors directly start building to do, but for four-stroke, the exhaust stroke cylinder pressure is low, and compression stroke gas cylinder pressure is very high, exhaust stroke and compression stroke co-ordination can not be realized, therefore conventional four stroke engine can not be used for.Straight moving electricity generating plan in " forced oscillation direct-action power generation, buffering accumulated energy, the electric drive automobile " that proposes in 200710004101.6 inventions proposes to utilize mechanical spring (or magnet) to form vibration system, piston relies on the electromagnetic force of vibration system and coil to drive during non-expansion stroke; The electric current that generator produces is by electric capacity buffering rear driving motor; This system realizes the stroke and the compression ratio optimization of piston by the method for coil current in the control generator, adjusts power by the devote oneself to work distance of destiny amount and aspirating stroke of control; The driving of valve utilizes the forced vibration system, the mode of electromagnetic force makeup energy also realizes that valve correctly opens and closes, and this system adopts compression-ignited work by the convenient compression ratio of adjusting, guarantee under wide operating mode, many fuel, to realize the mode of higher compression ratios, improve system effectiveness.

Straight moving electricity generating plan in " forced oscillation direct-action power generation, buffering accumulated energy, the electric drive automobile " that in 200710004101.6 inventions, proposes, adjust power by the devote oneself to work distance of number of cylinders and aspirating stroke of control, major defect is the frequency relative fixed, and the engine operation dynamic range is narrower; Additional belleville spring outside principal oscillation body (power coil, piston, helical spring and bindiny mechanism thereof), belleville spring does not have with the principal oscillation body fixedlys connected, when principal oscillation body compression belleville spring and after leaving belleville spring, belleville spring can enter dither, this can form noise, in addition at principal oscillation body next time to the compression initial stage of spring, the vibration phase of belleville spring is difficult to control, increase the cylinder operation phase difference of two symmetries, also can increase vibration and noise.Proposed the band acceleration spring in PCT/CN2008/071781 and the relevant domestic patent application and clapped the forced vibration direct-action power generation system of mechanism together, reduced the noise of forced vibration direct-action power generation system belleville spring, and realize frequency adjustable.

Forced vibration direct-action power generation system is in order to reduce the vibration of body, adopt the cylinder flat opposed, the mode of synchronous working, make body middle part stress balance, reduce vibration, but two generator units are arranged in the horizontal direction, two piston-cylinder units, vibrating spring is installed in beyond the cylinder body, is the head and the tail polyphone, and length is difficult to reduce.

The mechanical loss of conventional reciprocating engine piston accounts for about 50% of mechanical loss, the method that reduces the piston friction loss is mainly the raising machining accuracy, surface of good is handled, good is lubricated, and the less barrel shaped structure of employing friction, piston ring face and lower surface are sealing surface, and when pressure in the cylinder raise, upper surface and internal surface bore gas pressure, the pressure of internal surface makes side pressure raise, frictional loss is increased, and conventional scheme can adopt high-strength material, reduces the method for height of piston ring, reduce the side pressure of pressurized gas, but for proof strength, under same material, the thickness decrease has certain limit.

The heat transfer loss is the importance that influences engine efficiency, conventional engine is in order to raise the efficiency, need the optimized combustion cell structure, increase turbulent flow, accelerate velocity of combustion, need reduce turbulent flow and reduce the heat transfer loss, the two is a contradiction, therefore when chamber structure designed, main consideration improved velocity of combustion, seldom considered to reduce the heat transfer loss.

The band protection mechanism forced vibration system that in 200810009996.7, proposes; propose a kind of machinery and added protection mechanism and the double-power source energy-absorbing feedback solenoid driver circuit that electromagnet cooperates; the protection mechanism volume is bigger, and primary circuit figure can not realize illustrated function, and dual power source structure is complicated.

Summary of the invention

The technical solution adopted for the present invention to solve the technical problems is:

(1) major diameter hollow type transmission shaft, radial inner iron core structure reduces system length and weight

Two groups of vibrating springs of former scheme are installed on the pedestal in addition of cylinder block bottom, in order to guarantee stroke and intensity, the length overall of spring is longer, this case changes transmission shaft into the major diameter hollow type, vibrating spring lays respectively at inside and outside the transmission shaft, and the installing space of spring extends in the cylinder, has increased the installing space of spring, the corresponding system length that reduces makes design method more flexible; The directly moving electric machine iron core of former scheme is an end opening formula, transmission shaft links to each other with mover by the machinery of similar tubular, its minimum length is 2 times of strokes, simultaneously because flux circuit only passes through an end unshakable in one's determination, when adopting one pole (moving magnetic or moving-coil), required core volume is near the volume twice of two ends magnetic circuit, increased system weight, this programme is made inner iron core and end radial, magnetic flux is partly purchased into the loop by entity, radial transmission shaft link press span drives mover (magnet or coil) by the radioactivity slit of inner iron core, motor length is that stroke adds mover length like this, is about 1.5 times of stroke, simultaneously owing to adopt two ends magnetic conduction method, core section reduces, weight saving.

(2) the first piston ring adopts asymmetric drum degree shape

In engine mechanical loss, the loss of piston ring accounts for about 50% of total losses, and main loss is from the side pressure of piston, and side pressure is partly purchased by three, 1. the elastic force of piston ring; 2. bent axle rotates the side pressure that causes; 3. the side pressure that causes of highpressure, the side pressure that directly moving electricity generating plan does not have bent axle to rotate, main frictional loss is the side pressure that highpressure causes; For straight moving system, side pressure is balanced, the wearing and tearing of the thickness of casing wall are uniform, so the sealing of the elastic force of piston is reliable relatively, can reduce pressurized seal, this programme fully uses these characteristics to propose asymmetric drum degree piston ring, adopt the bucket degree that surpasses the machine oil film thickness on the top of piston (is the boundary with the maximum diameter), adopt normal bucket degree in the bottom, lower height is less than upper height simultaneously, when having pressurized gas, piston ring not only has upper surface, internal surface will bear pressure, and partly outer surface also will bear pressure, side pressure equals internal surface pressure and deducts outer surface pressure, so just reduced frictional loss, this scheme is the same with conventional scheme, reduce height of piston ring as far as possible, according to actual sealing surface height, reduce piston ring width, reduce side pressure, the pressure and the conventional design basically identical of the outer pressure-bearing surface of piston ring.

(3) piston is parallel and smooth shape with cylinder cap, reduces the heat transfer by convection loss

The heat transfer loss of firing chamber is the importance that influences engine efficiency, it is free to influence heat transfer rate, flowing state, temperature, area etc., the heat transfer time, temperature, area etc. and rotating speed, power is relevant, is not easy to adjust, because main heat transfer type is a heat transfer by convection, flowing state is very big to the influence of conducting heat, need increase turbulent flow but conventional engine improves velocity of combustion, will increase the heat transfer loss and increase turbulent flow, the two is difficult to take into account, this programme utilization is the characteristics of moving generating directly, adopt the homogeneous compression-ignition mode, improve velocity of combustion, adopt and simplify chamber structure, the method that reduces turbulent flow as far as possible reduces the heat transfer loss, recommend piston and cylinder cap to adopt the sphere of same curvature, make mixed gas parallel motion as far as possible, reduce turbulent flow.

(4) valve stem adopts dual grooved to connect and radial locking step, optimizes structure

In order to reduce the volume of valve locking framework, this programme valve end adopts the dicyclo slot type to connect, groove by valve retainer is used for fixing valve actuation armature, the end grooves top is and the corresponding homogeneous radiation shape of core step, drive core rotation respective angles by reducing motor and realize that the locking and unlocking of valve stem is installed in the inner space of valve electromagnet and valve spring whole locking framework, reduces volume.

(5) the valve actuation electromagnet adopts radial skeleton

In order to reduce the electromagnetic eddy loss of valve, the magnetic force of while guarantor unit's area, valve actuation electromagnet and driving armature should adopt silicon steel plate, and vertically stacked (silicon steel is unilateral parallel with valve stem), adopt radial for round structure, because valve actuation electromagnet and driving armature center are with holes, the stacked difficulty of silicon steel plate, this programme circular electromagnets is the twin nuclei that the bottom links to each other, in order to reduce the stacked difficulty of silicon steel plate, design is cast (or mold pressing) with silicon steel and is become two radial skeletons, the bottom be circular inside and outside radial bone photo company to be divided into circular arc with the silicon steel loop like this, has reduced stacked difficulty, driving armature core (in encircling in the electromagnet) is integral loop, and integral loop will be radiated the dress steel disc and be linked.In order further to reduce the silicon steel plate packing difficulty, the thin annulus in two roads or four roads can be set inside and outside valve actuation electromagnet installation silicon steel plate, thin annulus should be opened a vertical seam at least in each sector, at driving armature outer shroud one thin outer shroud is set, opens a vertical seam equally in each sector at least; Can adopt the high-resistance material of high-strength high temperature-resistant to make with upper skeleton, in this case, more than thin annulus is not provided with vertical seam, but can increase the electromagnet volume yet; For square EI shape electromagnet, drive " worker " font skeleton that armature can be made into the band center hole, the valve actuation electromagnet is made the bottom and is linked to each other, and vertically arranges 8 vertical skeletons.

(6) gate solenoid quickens drive circuit and adopts precharge high voltage electric capacity energy-absorbing feedback accelerating circuit

The subject matter of electromagnet type valve actuating mechanism needs big suction for the valve actuation electromagnet, under the situation that guarantees suction, inductance is bigger, be difficult to realize quick acting, it is big that electromagnet turn-offs consumed energy, existing electromagnet accelerating circuit is generally consuming type, and energy loss is big, is difficult to practical requirement.The band protection mechanism forced vibration system that in 200810009996.7, proposes; proposed a kind of machinery and added that electromagnet cooperates; band protection mechanism and double-power source energy-absorbing feedback solenoid driver circuit; protection mechanism is positioned at the DM outside; volume is bigger; drive circuit has adopted dual power source structure; drive circuit is complicated; circuit is wrong in addition, can not realize the function that illustrates, and this programme adopts and switches in advance to electromagnet; absorb the electromagnet cut-off current; and be stored in the high pressure energy-absorbing electric capacity, the later stage, the high voltage energy that control absorbs in the electric capacity discharged in the time of need quickening adhesive; realize that electromagnet quickens adhesive; cancel the high-voltage power part of former scheme, simplify circuit, and save the effect of energy consumption.
