Abstract

A cover combusting and boosting technique for compressed gas of a piston type internal combustion engine is composed of a piston, a connecting rod, a crankshaft, an air cylinder, a cylinder cover and a spark plug and is additionally provided with a flat compressing channel, an electromagnetic valve, an annular compressing chamber, an annular compressing chamber spark plug and an occupying piston ring. In a compressing stroke, the piston moves to an upper stopping point, most compressed gas is transferred into the annular compressing chamber, and a small part of compressed gas is kept in a pressure maintaining chamber. After the electromagnetic valve is turned off, the spark plug can ignite gas in the pressure maintaining chamber and the annular compressing chamber in an acting stroke, and the annular compressing chamber carries out cover combusting and boosting treatment on transferred fuel gas. Due to the facts that the internal combusting gas is ignited and no space is increased, the internal combusting gas is boosted. When the piston begins to move to a concave space opening in the internal lateral wall of the air cylinder from the upper stopping point, the piston can form a total combusting chamber with the pressure maintaining and combusting chamber, and then the piston is pushed to move downwards by the combusting gas in the pressure maintaining and combusting chamber to act. The combusting speed and the energy releasing speed in the total combusting chamber are far higher than those of a traditional internal combustion engine. Furthermore, turbulence can be generated, and combustion is fuller.

Description

Internal-combustion piston engine pressurized gas seals combustion supercharging technology

Technical field

The present invention relates to piston internal-combustion machine, especially can seal combustion pressurized treatment to ring pressure firing chamber by travelling backwards pressurized gas, then get involved total high combustion chamber pressures burning promotion descent of piston, and start acting with bent axle large arm of force transmission connecting rod power.

Background technique

No matter current known internal combustion engine is four-stroke, or two-stroke formula internal-combustion engine is in compression and expansion stroke, piston fuel gas be compressed to piston top dead center position in the cylinder, then the detonation of little drift angle is done work.In compression stroke, pressurized gas compresses supercharging in lifting compression ratio process, and not to the pressurized gas pressure treatment more completing compression ratio before starting to get involved the acting of promotion descent of piston, acting initial gas is forced down, and namely igniter gas forces down.

Meanwhile, little drift angle takes fire in acting situation, and now connecting rod is that radius flexing axle shaft axis rotates with bent axle, and the angle of formation is little, and the bent axle arm of force is just little, and the power around crank rotation transmission from connecting rod is just little.

Summary of the invention

technical problem to be solved:in order to overcome in existing internal-combustion engine expansion stroke, pressurized gas ignition-powering initial gas forces down the deficiency short with the bent axle arm of force, the invention provides a kind of internal-combustion engine arrangement, this internal-combustion engine can not only compressed fuel gas, detonation is done work, combustion gas, suck fuel gas, and pressurized gas can be shifted easily to pressurized treatment space, this space can close burning and the mode of Extended Spaces volume does not increase air pressure, i.e. pressurized combustion room, the pressurized combustion room of this case is described with ring pressure chamber example, ring pressure chamber piston from top dead center to lower dead center direction travelling backwards LAP near cylinder inner wall and piston outer wall between.

In expansion stroke, valve in solenoid valve has separated ring pressure chamber and pressurize room, pressurize room spark plug and ring pressure chamber spark plug successively ignition fuel gas, after igniting, ring pressure chamber is called as ring pressure firing chamber, pressurize firing chamber is called after the igniting of pressurize room, also can do pressurized gas in ring pressure firing chamber and seal combustion pressurized treatment in advance, after getting involved total firing chamber with very high acting initial gas pressure again, high pressure, high-velocity combustion promotes descent of piston acting, namely after ring pressure combustion chambers burn certain hour, gets involved the acting of total firing chamber again.

And realize the large arm of force of bent axle simultaneously, allow the power that connecting rod transmits, with the transfer mode turning crankshaft of the large arm of force of bent axle, the present invention is because only relate to compression stroke and expansion stroke, so in the following description and accompanying drawing only to this two and stroke be described, not the illustrating of exhaust and air-breathing part, and valve opens accompanying drawing partly.

the technical solution adopted for the present invention to solve the technical problems is:in piston type four-stroke and two-stroke internal combustion engine, ring pressure chamber and pressurize room are by flat pressure passage UNICOM, ring pressure chamber 12 is made up of outer concave space 111 liang of parts of concave space 112 in cylinder madial wall and piston outer side wall, in this case, the interior concave space of cylinder madial wall is referred to as interior concave space, as 112 in Figure 13.The outer concave space of piston outer side wall, referred to as outer concave space, as 111 in Figure 13, is also called ring pressure firing chamber after igniting.

Solenoid valve 5 is provided with in flat pressure passage 18, in compression stroke, as shown in Figure 2, solenoid valve 5 is opened, the compression stroke of pressurized gas after piston 6 goes upward to the opening of energy closed loop pressure chamber 12, by flat pressure passage 18 gimbal pressure chamber 12 and pressurize room 15 air pressure inside, solenoid valve 5 is held open state in compression stroke end stage, on the opening allowing piston 6 have passed through ring pressure chamber 12 in up process along after, continue to carry air pressure through pressurize room 15 to ring pressure chamber 12 by flat pressure passage 18.

The most fuel gas played a major role as the descending acting of promotion piston 6 is stored ring pressure chamber 12, realizes the travelling backwards of pressurized gas part.Small part fuel is deposited in pressurize room 15, and pressurize room volume size is with after the igniting of its inner fuel, and maximum gas pressure can make piston 6 come downwards to ring pressure firing chamber 91 opening distance from top dead center to be as the criterion, and position corresponding is in fig. 2 the interior concave space 112 of cylinder inner wall.

In compression stroke, piston continues to be up to atdc, and solenoid valve 5 cuts out, isolated ring pressure firing chamber 91 and pressurize firing chamber 90, ring pressure chamber spark plug 16 and pressurize room spark plug 19 are lighted a fire respectively, now, in pressurize firing chamber 90, gas takes fire, and air pressure raises, piston 6 starts descending, descending distance is exactly that ring presses the opening of firing chamber 91 to be as the criterion when rising to maximum with the atmospheric pressure value of pressurize firing chamber, that is, the interior concave space 112 of cylinder inner wall.

The time period before the opening of ring pressure firing chamber 91 is not also come downwards at piston 6, ring pressure firing chamber 91 gas also can burn in premature ignition, seal combustion pressurized treatment, treat that piston 6 continues descending after the opening of ring pressure firing chamber 1, interior concave space 112 and pressurize firing chamber 90 UNICOM of cylinder inner wall form total firing chamber 100.

Ring pressure inside, firing chamber 91 is through sealing the high-pressure combustion gas of firing pressurized treatment in advance, total firing chamber 100 is got involved by opening with higher acting initial gas pressure, burn together with the combustion gas of pressurize firing chamber 90 and promote the descending acting of piston 6, form turbulent flow simultaneously, make burning more abundant.

Sealing combustion pressurized treatment technology is: compression stroke completes and shifts fuel gas to plenum space, start expansion stroke again, the ignition in enclosed space ring pressure chamber 12 when not having combustion space to increase, to increase the air pressure of space fuel gas, adapter ring firing chamber spark plug 16, control advancement amount firing time, Timing Advance just can be, zero-sum negative value, in this incidence of criminal offenses with Timing Advance on the occasion of being described as an example, so that not easily by lighting, supercharging is too too early for the fuel gas in ring pressure firing chamber 91, the incipient stage of burning is only utilized to occur in ring pressure firing chamber 91, combustion phase afterwards, piston 6 has come downwards to the opening of ring pressure firing chamber 91, connecting ring presses firing chamber 91 and pressurize firing chamber 90 to form total firing chamber 100, higher according to pressure, temperature is higher, the principle that velocity of combustion is faster, so the fault offset speed of fuel is faster.

Through sealing the combustion gas firing pressurized treatment and cross in advance, total burning 100 is joined at the opening of piston 6 through ring pressure firing chamber 91 with higher pressure, just start the descending acting with piston, compared with traditional combustion engine, without the compressed fuel gas sealing combustion pressurized treatment in advance, only with complete compression ratio increase the pressure values that air pressure reaches, direct ignition just starts with the descending compression and combustion gas of piston 6, its initial combustion air pressure starting to do work will exceed a lot, namely gets involved acting initial combustion air pressure and will exceed a lot.

Its firing effect in total firing chamber is more excellent, and fault offset speed is faster, and combustion reaction is more abundant.In cylinder, the pressure growth rate of total firing chamber 100 can be faster, and detonation better effects if, acting effect is also better.

When concave space in cylinder inner wall 112 forms total firing chamber 100 with pressurize firing chamber 90 UNICOM, point is got involved at this, from piston 6 top dead center, 8 turns, a connecting rod 7 flexing axle angle Q, as shown in Figure 10, this angle Q is greater than the angle of the little drift angle igniting of traditional combustion engine, and connecting rod power 131 is that on radius flexing axle central axis, the rotation of Z point forms larger arm of force L with connecting rod power 131 with crank axle 132.Initial at each expansion stroke of internal-combustion engine, connecting rod 7 has large arm of force L turning crankshaft 8, and the ouput force of bent axle 8 is just larger.

Piston 6 from it stop backspace runs to this segment distance of ring pressure firing chamber 91 opening, namely doing the stage before function pressurized gas intervention promotion piston 6 does work, is also the stage that the large arm of force of bent axle is formed simultaneously.

Piston 6 travelling backwards, space, pressurize firing chamber 90 in cylinder is caused to increase, by ignition deflagrating of hot by the fraction pressurized gas stayed in pressurize room 15, bulked volume fills the space that piston 6 travelling backwards increases, during to guarantee that doing function combustion gas gets involved total firing chamber 100 from ring pressure firing chamber 91, air pressure that air pressure goes to make up pressurize firing chamber 90 can not be lost lower than atmospheric pressure value when completing compression stroke, namely descent of piston increase the draught head that space formed.

For guaranteeing that the atmospheric pressure value of the combustion gas doing function is got involved into total firing chamber 100 from ring pressure firing chamber 91, just to be greater than, at least equal atmospheric pressure value during compression ratio.

In ring pressure chamber 12, the pressurized gas of the inside is done and seal combustion pressurized treatment in advance, with certain hour amount igniting before the total firing chamber 100 of intervention in advance, the high pressure combustion when not having space to increase, supercharging not expansion space, its velocity of combustion can higher than the velocity of combustion of the pressurize firing chamber 90 increased with burning that has living space, add that most fuel leaves in ring pressure chamber 12, namely the burning air pressure that the air pressure that do not burn promotion piston expansive space increases and velocity of combustion can increase burning air pressure and the velocity of combustion in space higher than there being piston to run, its velocity of combustion and burning air pressure can manyfolds by force.

The control of firing chamber spark plug 16 electronic spark advance amount can be pressed with ring, control easily to seal the air pressure firing pressurized treatment and increase in advance.When piston 6 go downwards to ring pressure firing chamber 91 opening form total firing chamber 100 time, combustion gas with the total firing chamber 100 of the intervention of the air pressure higher than pressurize firing chamber 90, then are burning and promote the descending acting of piston 6.

At double-piston opposed type, as shown in figure 12, also can design pressurized gas travelling backwards and seal combustion supercharging technology, seal A ring pressure chamber 131, B ring pressure chamber 132, the C ring pressure chamber 133 of combustion supercharging technology, D ring pressure chamber 134, design the inwall in portion in the cylinder respectively, i.e. the near top dead center of two pistons, as shown in figure 12.

In Figure 12 47,48,49,50 is the supporting A solenoid valves of each cylinder, B solenoid valve, C solenoid valve, D solenoid valve, and supporting A ring pressure chamber 141, B ring pressure chamber 142, C ring pressure chamber 143, D ring pressure chamber 144.Double-piston opposed type in Figure 12 is that each piston devises ring pressure firing chamber and seals combustion pressurization system.Also only Aided design can be done to part piston group.

The solenoid valve 5 of design in flat pressure passage 18, in suction stroke and exhaust stroke, two valves 31 of solenoid valve 5 and valve 27 are all opening states, as shown in Figure 8, gas is facilitated to circulate, in compression stroke end and expansion stroke, namely ring pressure firing chamber 91 is done and is sealed the combustion pressurized treatment stage in advance, be located at the solenoid valve 5 in flat pressure passage 18 separation of pressurize room 15 and ring pressure chamber 12 is played an important role, namely will in compression stroke, pressurized gas be allowed to circulate, the draught head realizing the successively ignition of two firing chambers again in expansion stroke circulates no longer mutually, and preferably work in totally enclosed situation, so the valve that electromagnet control has special construction can be competent at, the valve 31 of the less shape of the large another end in one end and valve 27, as shown in Figure 14, larger with draught head, folding obtains better, particularly valve after closing.

In expansion stroke, first light a fire in pressurize firing chamber 90, air pressure first raises, now the air pressure of pressurize firing chamber 90 is higher than ring pressure firing chamber 91, in expansion stroke when side, pressurize firing chamber 90 pressure presses the pressure of side, firing chamber 91 higher than ring, valve 31 is withstood on flat pressure passage 18 by highpressure on the end opening of pressurize firing chamber 90 firmly from direction, pressurize firing chamber 91, after also lighting a fire in ring pressure firing chamber 91, flat pressure passage 18 leads to ring pressure firing chamber 91 opening end air pressure because be that combustion mode of the sealing velocity of combustion that do not have space to increase is faster, and most fuel leaves in ring pressure firing chamber 91, so air pressure is now higher than pressurize firing chamber 90, the highpressure of ring pressure firing chamber 91 also withstands on valve 27 on ring pressure direction, firing chamber 91 opening of flat pressure passage 18 firmly, as shown in figure 14.

No matter be compression stroke or expansion stroke, the folding of solenoid valve 5 and flat pressure passage 18 does not all have have space to communicate with outside cylinder 4, achieve totally-enclosed, and two valves are connected by solenoid valve lever 22, as long as a valve promotes by highpressure, power also can allow another valve-closing obtain better by solenoid valve lever 22, adds the active force of electromagnet 29 and electromagnet 25, initiatively can close valve.

Ring pressure chamber 12 ring pressure firing chamber spark plug 16 is therein called as ring pressure firing chamber 91 after lighting a fire, on the opening that piston 6 comes downwards to concave space in cylinder inner wall along 121 before, ring pressure chamber 12 is by the outer concave space 111 of piston outer side wall, with can work the opening depositing combustion gas and be enclosed in concave space in cylinder inner wall under form, as the ring pressure chamber 12 in Figure 13 along 122 liang of parts.

Namely, along 121 and lower between 122 on the interior concave space 112 of the outer concave space 111 place cylinder inner wall of piston outer side wall, can be used to deposit fuel gas and closed ignition seal combustion supercharging and manage outward, the outer concave space 111 of piston outer side wall refers to the space of piston body and each piston ring ecto-entad depression, concave space and branch's state of various shape can be designed to arbitrarily, as being asterism branch.For annular branch in this case, comprise upper piston ring 14 and account between piston position the ring 11 and space do not contacted with cylinder inner wall, as shown in figure 13, ring pressure chamber 12 is called before this part space igniting, ring pressure firing chamber 91 is also called after igniting, pressurize room 15 is called pressurize firing chamber 90 after the pressurize room spark plug 19 at cylinder top is lighted a fire, main plaing a part ensures air pressure, when in descent of piston to cylinder inner wall concave space 112 on along 121 places, the interior concave space of cylinder inner wall 112 and pressurize firing chamber 90 UNICOM form again total firing chamber 100.

In tool the present embodiment: ring pressure chamber 12 is primarily of concave space in cylinder inner wall 112 by structure, and outside the space of piston 6 aspect except each piston ring, do not design special outer concave space, ring pressure chamber 12 is made up of concave space in cylinder inner wall 112.

Be positioned at the piston occupy-place ring 11 on piston 6, its position, thickness and width are, when piston 6 is in top dead center, it is lower to arriving ring pressure chamber 12 times beads downwards, i.e. interior concave space 112 lower to 122 of cylinder inner wall, along edge on not closed loop pressure chamber 12 opening on it, namely cylinder inner wall interior concave space 112 on along 121, its thickness occupies space between piston 6 and cylinder 4 as far as possible, and don't have larger friction with cylinder 4, work the effect of taking up space, space between piston and cylinder body is occupied when descent of piston, ring is allowed well to press the fuel gas more Thorough combustion in total firing chamber 100 of firing chamber 91.

Cylinder inner wall in plenum space and ring pressure chamber has piston sliding bridge to slide past for piston, and piston sliding bridge is offered have hole, allows well fuel gas negative circulation mutually.

beneficial effect:can while compression stroke compressed fuel gas travelling backwards pressurized gas, burn the igniting of indoor certain hour amount in advance at ring compression ignite to do fuel gas and seal combustion pressurized treatment in advance, improve the initial combustion atmospheric pressure value of the intervention acting of fuel gas, atmospheric pressure value when this atmospheric pressure value completes far above compression ratio, the burning making to occur in the indoor fuel gas of total combustion more fully and at a high speed, before piston arrives lower dead center, cylindrical implosion combustion better effects if, air pressure is higher.Add the turbulence effect getting involved total firing chamber, burn more abundant, while allowing internal-combustion engine export larger torsion and power, more energy-conserving and environment-protective.

It take bent axle as radius flexing axle central axis that power simultaneously on connecting rod can obtain the large arm of force easily, and the power of bent axle is just larger.

This seals combustion supercharging technology, ring compression ignite make a fire spark plug ignition Timing Advance control under, can obtain transformable intervention acting initial combustion air pressure, its transformable atmospheric pressure value scope is larger than changeable compression ratio technique, can exceed a lot and much lower.

Because ring pressure firing chamber just gets involved total combustion room work by combustion at descent of piston through its opening, when opening is just connected, ring compression ignite burns indoor high pressure air cognition and flows to total firing chamber, form the high velocity turbulent flow be burning, the mode flowed is burnt, can the oxygen be in cylinder periphery corner, carbon, and the carbon monoxide molecule not having Thorough combustion to be formed fully coordinates in flowing, the carbon that is in oxygen molecule thin area and carbon monoxide is allowed to have an opportunity to obtain oxygen unit, Thorough combustion.

embodiment:in single cylinder list piston type, from compression stroke, the compression and travelling backwards of expecting right gas is completed through three stages, first stage, as shown in Figure 1, piston 6 advances from lower dead center to top dead center, intake valve 1 and exhaust valve 2 are closed, solenoid valve 5 is opened, its unfolding mode as shown in Figure 8, is produce magnetic force by A electromagnet 25 to pull B iron block 24 to be rotated clockwise around solenoid valve central shaft 33 by solenoid valve lever 22, import valve 31 upwards jack-up, outlet valve 27 is pushed open downwards simultaneously, complete breakdown action.

Import valve 31 is contained in A to prop up in the slide opening of title sleeve column 30, and outlet valve 27 is contained in B to prop up in the slide opening of title sleeve column 26, can slide up and down.

Second stage, as shown in Figure 2, when piston 6 is advanced to concave space 112 opening in cylinder inner wall, namely, along 121 on the opening of the interior concave space of cylinder inner wall, it is opened in 1/10 to ten/13rd place that piston 6 top dead center is moved back into the whole stroke of piston.

Along 121 on the opening that upper piston ring 14 arrives the interior concave space of cylinder inner wall, along 121 on the opening that occupy-place piston ring 11 upper end does not arrive the interior concave space of cylinder inner wall, its lower end also in cylinder inner wall concave space opening under along 122 places, the interior concave space 112 of cylinder inner wall is closed opening by the upper piston ring 14 of piston 6 and occupy-place piston ring 11, form ring pressure chamber 12, in the compression stroke end stage of remainder, pressurized gas can only flow to ring pressure chamber 12 by the solenoid valve 5 of flat pressure passage 18 through opening from pressurize room 15.

Phase III, as shown in Figure 3, piston 6 continues to push up to its top dead center along 121 from the opening of concave space in cylinder inner wall, completes compression stroke.

Solenoid valve 5 cuts out, as shown in figure 14, its closedown mode produces magnetic force moving A iron block 23 by electromagnet 29 solenoid valve lever 22 is rotated counterclockwise around solenoid valve central shaft 33, and import valve 31 is pulled down, outlet valve 27 is upwards pulled simultaneously, complete closing motion.Pressurized gas success travelling backwards, and seal up for safekeeping respectively in the pressurize room 15 shown in Fig. 3 and ring pressure chamber 12.

Next be expansion stroke, as shown in Figure 4, piston 6 is downward operation from top dead center, does seal right pressurized treatment in advance at the pressurized gas of ring pressure firing chamber 91 to its inside.

Also will through three stages, the first stage, as shown in Figure 4, intake valve 1 and exhaust valve 2 are closed, and solenoid valve 5 is closed.The pressurize room spark plug 19 at top, pressurize firing chamber 90 starts igniting, pressurized gas takes fire, air pressure raises, piston 6 from it stop starts descending, bent axle 8 starts to rotate clockwise from twelve-hour point position, piston 6 goes downwards on the opening of ring pressure firing chamber 91 along place, namely, along 121 on the opening of the interior concave space of cylinder inner wall, in pressurize firing chamber 90, the burning of that little part fuel gas makes its air pressure inside reach peak, now pressurize firing chamber 90 and ring pressure firing chamber 91 between by top piston ring 14 across, piston ring 14 and occupy-place piston ring 11 also enclose ring pressure firing chamber 91, as shown in Figure 4.Just at top piston ring 14 with piston 6 on the descending opening leaving ring pressure firing chamber 91 before edge, namely, along 121 on the opening of the interior concave space of cylinder inner wall, namely be communicated with the interior concave space 112 of pressurize firing chamber 90 and cylinder inner wall, before forming total firing chamber 100, total firing chamber 100 as shown in Figure 5.

The also premature ignition of ring pressure firing chamber spark plug 16, figure as indicated at 4, pressurized gas in ring pressure firing chamber 91 seals combustion pressurized treatment in advance, piston 6 is descending presses edge on the opening of firing chamber 91 through ring, namely, along 121 on the opening of the interior concave space of cylinder inner wall, form total firing chamber 100 as shown in Figure 5, through sealing the pressurized gas firing pressurized treatment in advance, total firing chamber 100 is got involved by ring pressure firing chamber 91 opening with higher initial pressure values, the descending acting of piston 6 is promoted, shown in Fig. 5 together with the combustion gas of pressurize firing chamber 90 before.Because there is the design of occupy-place piston ring 11, its wider width, along with piston 6 times, upper piston ring 14 touch under ring pressure firing chamber 91 opening along time, namely, time under the opening of the interior concave space of cylinder inner wall along 122 place, combustion gas between upper piston ring 14 and occupy-place piston ring 11 are minimum as far as possible by the amount taking away total firing chamber 99, this fractional combustion gas does not participate in acting, as piston in Fig. 56 runs to lower dead center, just when total firing chamber 100 has just started to form, this part is taken away total firing chamber 99 combustion gas and is not promoted descent of piston acting.

When bent axle 8 is also descending from top dead center by piston 6, the twelve-hour of its correspondence is urged position O point and has been forwarded some J place to, as shown in Figure 10, and connecting rod power 131, be that some Z on radius flexing axle central axis rotates clockwise angle Q with crank axle 132, form larger arm of force L.Namely piston present position bent axle 8 turns 15 degree during from twelve-hour position is equaled best, the J point as shown in Figure 10.The power of connecting rod 7 top is with large arm of force L turning crankshaft 8, point J gets involved as the pressurized gas through sealing combustion pressurized treatment in advance the intervention point that total firing chamber 100 starts to do work to piston 6, be compared to all fuel gas of traditional internal combustion engine at piston 6 top dead center little drift angle ignition-powering, namely bent axle is in twelve-hour position, and the arm of force obtained is much bigger.And through to seal in advance combustion pressurized treatment its to get involved acting initial combustion atmospheric pressure value much higher.
