Embodiment
As shown in Figure 1, 2, cylinder gas distribution type two-stroke engine, be multicylinder engine, comprise a work done cylinder 1 and several air distribution cylinder 2, its groundwork part is made up of air inlet, exhaust, lubricated, cooling, fuel supply, igniting, body and rotation system.
Work done cylinder 1 and air distribution cylinder 2 are tied together, and valve 4 between cylinder is established in the centre.The air flue that connection is arranged under the top top dead center of the air distribution cylinder 2 of several connections arranged side by side.The suction port 4,4 of work done cylinder 1 also is a valve port, and the air outlet by valve and air distribution cylinder communicates.So that the gas of air distribution cylinder is pressed into firing chamber and its work done cylinder by valve.
The relief opening 5 of work done cylinder 1 be located at work done cylinder 1 middle part, lower dead center A above.It is the same with the two-stroke gasoline exhaust opening of engine of using at present, opens or closes relief opening by moving up and down of piston.
The connecting rod piston 6 of air distribution cylinder 2 and the connecting rod piston 6 of work done cylinder 1 are located on the same bent axle 7, and bent axle 7 is provided with the cam 10 that valve 4 opens and closes between control cylinder.When several pistons of air distribution cylinder moved up and down, its mobile position was almost all on same horizontal line.Very little angle is arranged, so that adapt between each piston with gas flow.To improve the power of motor.Gases in the air distribution cylinder 2 are to be provided with the upper airway flow that communicates in the work done cylinder 1 that is attached thereto by its top.
Establish tilt fixing between the bent axle 7 of air distribution cylinder 2 and the bent axle 7 of work done cylinder 1, to help the normal operation of motor.The setting of angle should be satisfied: when the piston 6 of air distribution cylinder 2 was moved upwards up to the neutral position of cylinder 2, the piston of work done cylinder 1 was moved down into the position of the lower dead center B of cylinder 1.
One, the working condition of cylinder gas distribution type two-stroke engine is divided two-part introduction
1. air distribution cylinder working condition: begin to move to lower dead center from top dead center when several pistons of air distribution cylinder, just produced vacuum in the cylinder, the suction port of air distribution cylinder is outside under the atmospheric pressure effect, air valve on the intake valve is opened, the air (mixed gas) that flows to intake valve through Carburetor flows to cylinder, when the piston arrives lower dead center, air (mixed gas) is full of cylinder, air valve on the intake valve is closed under the effect of spring like this, when piston is moved upwards up to the neutral position of cylinder, certain pressure has been arranged in the cylinder, at this moment the valve between air distribution cylinder and the work done cylinder is backed down by cam, the gas (mixed gas) that has certain pressure flows to the work done cylinder by valve, and when its top dead center of the piston arrives of air distribution cylinder, the gas (mixed gas) in the air distribution cylinder all is pressed into the work done cylinder.At this moment air distribution cylinder and the work done cylinder valve-closing between them, air distribution cylinder is finished a work cycle like this.
2. the working condition of work done cylinder: the piston of work done cylinder moves up and down it and will or close the Exhaust Open below the cylinder in cylinder, the size of relief opening can be regulated, make air distribution cylinder after the work done cylinder is pressed into gas (mixed gas), inflammable gas can not discharged from relief opening, and expense gas has been arranged substantially.
When the piston of air distribution cylinder during to top dead center, gas (mixed gas) in their several cylinders all is pressed into work done cylinder and its firing chamber, at this moment the valve-closing between air distribution cylinder and the work done cylinder, at this moment the piston that is moved upward of the relief opening of work done cylinder is blocked, when the piston of work done cylinder continues to move to top dead center, compressed gas temperature rising, air pressure strengthen in the firing chamber, after spark plug (or high-pressure diesel) was lighted, the high temperature and high pressure gas of burning promotion piston moved down and work done rapidly.Because the firing chamber area of this motor work done cylinder is big, and sufficient available gas pressure is arranged, thus can be a lot of greatly during its burning to the pressure of the piston pressure when using engine combustion now, make piston when moving down, export very strong power.
The piston of work done cylinder moves down when spilling relief opening, and High Temperature High Pressure waste gas is discharged rapidly from relief opening, when piston moves to after bottom dead center, and the most of cylinder of discharging of waste gas.At this moment the valve between air distribution cylinder and the work done cylinder is opened, the piston of air distribution cylinder and work done cylinder moves up simultaneously, the air distribution cylinder piston pressurized gas (mixed gas) that moves up flows to the work done cylinder, and the relief opening of the waste gas of work done cylinder from cylinder outwards extruded.
The piston of work done cylinder is discharged waste gas to the gas that the work done cylinder is pressed into jointly in conjunction with air distribution cylinder when lower dead center moves up from relief opening.When the piston of work done cylinder was blocked relief opening, the waste gas of work done cylinder had been arranged substantially.The piston of air distribution cylinder does not also arrive its cylinder top dead center, the piston of air distribution cylinder and work done gas is pressurized gas (mixing gas) upwards simultaneously, when air distribution cylinder piston during to top dead center, it has finished distribution work, at this moment the piston of work done cylinder has arrived the neutral position of its cylinder, valve-closing between air distribution cylinder and the work done cylinder, at this moment the piston of work done cylinder upwards compresses (mixed gas) gas in its cylinder separately, to top dead center by spark ignitor and work done.The work done cylinder is finished a work cycle.
Cylinder gas distribution type two-stroke engine can divide two types
One, cylinder gas distribution type two-stroke petrol engine
It is the same with present petrol engine oil-feed system
Two, cylinder gas distribution type two-stroke diesel engine:
It is the same with present diesel engine injection system
1. the cylinder gas distribution type two-stroke petrol engine it to the firing chamber, the gas of supply is gas-air mixture, utilizes electrical spark to light air Mixture and work done.
2. the cylinder gas distribution type two-stroke diesel engine it be pure air to the gas of firing chamber supply because compression ratio is higher, temperature has reached diesel oil combustion condition voluntarily when high pressure, the diesel oil that sprays into is ablaze voluntarily.
3. the rotation of motor at first must have external force that bent axle is rotated, and makes to carry out air inlet and compression process, after mixture combustion expands the work done of promotion piston, because the inertia energy of bent axle and storage flywheel must carry out other stroke circularly in continuation.
4. the injection time of the firing time of petrol engine and diesel engine was all implemented before the piston arrives top dead center, and correspondingly adjusted advance angle along with the quickening of engine speed.
5. the air distribution cylinder of diesel engine can be more than petrolic cylinder, in just increasing combustion chamber volume, make combustion chambers burn gas send efficient pressure to piston.
6. its air distribution cylinder quantity of cylinder gas distribution type two-stroke engine petrol engine is 2 to 4 cylinders, and the combustion chamber volume of work done cylinder is answered mutually in fact with the quantity of this air distribution cylinder, sends best power source in the interests motor.
The air distribution cylinder quantity of cylinder gas distribution type two-stroke diesel engine can be 3 to 7 cylinders, and work done combustion chamber of air cylinder volume is answered mutually in fact with the quantity of this air distribution cylinder, sends best power source in the interests motor.
Its air distribution cylinder piston of cylinder gas distribution type two-stroke engine and work done cylinder piston are when moving up and down, and gas pressure can change in the engine crankcase.Gas pressure change reduces in the crankcase in order to make, and makes the interior gas pressure of engine crankcase should not ring the power of motor output, introduces several ways below.
(1) utilize gasoline to mix machine oil under certain proportion, the rotating mechanism of their mixed gas in crankcase flowed to again the suction port of air distribution cylinder, rotary parts in the crankcase can be lubricated again like this, can reduce piston crankcase internal air pressure when moving up and down again and change.
(2) the organic oil pump of the crankcase of this motor, the rotary parts of depended on pressure oil lubricating crankcase, its crankcase have pipeline to lead to the suction port of air distribution cylinder, the gas pressure in reducing crankcase.
(3) two gas distribution type two-stroke engines are combined their crankcase is communicated, their piston is when mobile like this, and an engine piston moves up, and the piston of another motor moves down, the air-flow of their inside enemy mutually disappears, and gas pressure is more gentle at crankcase.
The relief opening of cylinder gas distribution type two-stroke engine can be regulated, and the exhaust angle of relief opening will change like this, the angle when corresponding angle that has changed work done cylinder pressurized gas and outburst gas.Main purpose is in order to reduce should ringing of engine output when the variation of engine speed or under the negative condition what changes, regulate the clean Cheng Du of discharging waste gas when discharging waste gas as far as possible.And whether mixed gas is run out of situation from relief opening and is regulated.
The cylinder gas distribution type two-stroke engine distribution device is arranged and is divided two kinds:
Side-located gas-gate and Overhead valve
Side-located gas-gate
Some is different for the side-located gas-gate of cylinder gas distribution type two-stroke and the side-located gas-gate that uses now, the side-located gas-gate of gas distribution type two-stroke engine is between work done cylinder and air distribution cylinder, its valve Push And Release is controlled the air distribution cylinder air outlet is pressed into time from gas to work done combustion chamber of air cylinder, its lower end of side-located gas-gate can directly be pushed up between air distribution cylinder and the work done cylinder on the cam on the bent axle, valve is just in time opened because bent axle turns around, close once, if air distribution cylinder is pressed into gas pressure condition to working cylinder and allows, the Push And Release of valve is just opened and is closed without cam, come unseat the valve to the firing chamber air feed and make by the air distribution cylinder piston pressure that pressurized gas produced when moving up, valve was closed automatically after air feed was finished.
Overhead valve
The Overhead valve of Overhead valve gas distribution type two-stroke engine be arranged on air distribution cylinder above have air flue to lead to the firing chamber of work done cylinder through valve, because valve is at cylinder and external engine, this just need be provided with rotating mechanism at external engine and open or close valve, can open or close valve by depended on pressure if air distribution cylinder is pressed to the gas of firing chamber, that will save the required driving mechanism of unseat the valve.
Introduce the gas distribution type two-stroke engine of an air distribution cylinder below:
Its air distribution cylinder of air distribution cylinder is big. and the work done cylinder is little, do not use a unified bent axle, same big gear phase interlock is arranged between their bent axles, air distribution cylinder turns around, the work done cylinder turns around too, it is just the same to the condition of work done cylinder intake with polygamy gas cylinder like this, can proper functioning.Other condition of single cylinder gas distribution type two-stroke engine is the same substantially with multi-cylinder distributing type motor.The practical Overhead valve of the valve of this air-distribution engines.It is compared with the multi-cylinder air-distribution engines, and its height and width strengthen. and length is littler, can use under the condition that is fit to.
The intake valve setting of air distribution cylinder
The suction port of air distribution cylinder is at it above the cylinder, and several air distribution cylinders can height have one or two towards gas port.Valve on its suction port opens or closes suction port by the gas flow pressure size.
The relief opening of gas distribution type two-stroke engine divides two kinds of forms: 1, adjustable relief opening, 2, do not have a fixedly relief opening of mode.
(1) adjustable relief opening is provided with two or three relief openings, in these two or three relief openings, has only a relief opening to be provided with controlling device.
(2) relief opening that is not provided with controlling device is fixing relief opening.
It compares cylinder gas distribution type two-stroke engine with the advantage of using motor now:
One, cylinder gas distribution type starts its power output bigger:
The four-stroke engine that uses is many now, and cylinder gas distribution type two-stroke engine compares at the present use motor with the as much cylinder: all come comparison by four cylinders.1. represent the cylinder gas distribution two-stroke engine; 2. represent the Cylinder Four-stroke of use now.
1. cylinder gas distribution type two-stroke engine it the time go around in acting and just do merit one time, its four cylinders are divided into 1 work done cylinder and 3 air distribution cylinders, it is goed around so just the interior available gas work done of 3 cylinders, it changes two and changes the gas output power that just has in 6 cylinders, has more the power of two cylinder outputs than the motor of present use.Higher because of its rotating ratio again, so it is bigger than the engine power of present use.The available gas that its maximum characteristics of distributing type motor make energy product close several cylinders arrives together, the volume energy that makes the firing chamber is than big several times of the engine chamber volume that uses now, combustion chamber volume is optimized, this has just made full use of hot energy after gas is lighted, and breaks into more intense pressure and temperature promotion piston and moves down and export bigger power with very high speed.Because is rotating once changeing work done once the raising of rotating speed and it,, or be doubled and redoubled so it can be a lot of greatly than the engine power of present use.
2. present four-stroke engine changes just outburst once because of its each cylinder changes two, just can know that by changeing two commentaries on classics the motor of 4 strokes, 4 cylinders made merit 4 times now, its available gas in 4 cylinders that burnt has been exported 4 power that cylinder gas generated.Its several cylinders of multicylinder engine that use are all in work done now, its each cylinder can only rely on its volume own to the available gas volume that certain share is provided oneself, its combustion chamber volume is restricted, interests heat utilization efficiency not, and each cylinder combustion gas waiting time in firing chamber and cylinder when work done is long, body with regard to intussusception many heats, thermal loss strengthens, engine output is smaller.
Two, good cooling results:
1. the period of exhaust of cylinder gas distribution type two-stroke engine is shorter, it is to open or close relief opening by moving up and down of piston for a cylinder gas distribution type two-stroke engine, when spilling relief opening to the cylinder bottom, descent of piston begins exhaust, block relief opening to up piston, its crank angle degree is a hexagonal angle, move down at piston and to spill relief opening and begin exhaust, calm the anger to cylinder from the firing chamber to air distribution cylinder, the gas that the piston of work done cylinder and air distribution cylinder are pressed to the work done cylinder is jointly waste gas to be discharged through relief opening, because efflux time is shorter, make high-temperature gas discharge rapidly, make this motor be unlikely to overheated.The waiting time of the combustion gas of this motor in cylinder is 240 ° of angles.Again because of the gas intussusception that is pressed into the work done cylinder from air distribution cylinder the certain heat the work done cylinder block, this machine cools off.
2. present multicylinder engine is when work done, and combustion gas crank angle degree of the waiting time in cylinder is that 360 ° of cylinder gas distribution motors exceed hexagonal angle.The combustion gas angle is 180 ° of angles.Cylinder gas distribution type two-stroke engine exceeds 60 ° of angles, and it is bad that this just leads the engine exhaust of having made present use, and heat waste strengthens, and the power raising is restricted.
Three, the volume of cylinder gas distribution type two-stroke engine is little, and is in light weight, simple in structure.
1. the work done cylinder of cylinder gas distribution type two-stroke engine has only one, other is an air distribution cylinder, have only the body of work done cylinder to require outside the very high intensity, other several air distribution cylinder temperature are not high, use the volume and weight of material can reduce a part, have only valve one or two because of several cylinders again, the valve of air distribution cylinder does not have complicated driving mechanism, it is to open or close intake valve by the size of gas pressure change is flat, so the volume of this motor is little, lightweight structure is simple.
2. each cylinder of present multicylinder engine is all in work done, the intensity of each cylinder all must be equally very strong, material uses than higher, because each cylinder all has two valves and the needed rotating mechanism of valve, so just makes that the motor volume is big, weight is big, mechanism is complicated.
Four, it is long that cylinder gas distribution type is sent out the time that motor uses:
1. its firing chamber area of cylinder gas distribution type two-stroke engine is bigger, the air feed abundance, stable gas pressure, like this, motor after using for a long time, the pressure in the time of also can not reducing combustion gas piston is moved down.Because of the piston ring on the air distribution cylinder piston is not subjected to the gas combustion effects, it is lower to wear and tear, so service life is long.
2. each cylinder of multicylinder engine that uses now is all in work done, piston weares and teares bigger in cylinder, be to produce gas leak phenomenon like this, the pressure when limited combustion gas are moved down piston because of having run some gases but power descend, reduce service life.The long-time work done Yin Gaowen of this cylinder, and make the air inlet deficiency,
Five, the stability of rotation of cylinder gas distribution type two-stroke engine, noise ratio is lower:
1. the combustion chamber volume of cylinder gas distribution type two-stroke engine is big, and the gaseous combustion back piston moves down, and cylinder top combustion gas volume increases, and pressure can not reduce rapidly, therefore can not produce phenomenon of detonation, and it is more stable to work together, and noise ratio is lower.
2. the multicylinder engine that uses now is because its single cylinder air inlet separately, and this just makes the volume ratio of firing chamber less, though after gaseous combustion to the pressure of piston in the cylinder gas volume increase rapidly, and the pressure of piston is reduced than comparatively fast.Engine vibration is strengthened, and send bigger noise.
Six, its power of cylinder gas distribution type motor can be smaller also can be bigger
1. its volume of cylinder gas distribution type two-stroke engine do very little also can proper functioning, this is because the firing chamber of its work done cylinder can reach the optimal volume of gas when minimum burning limit, makes this gas distribution type two-stroke engine can make tiny engine.Cylinder gas distribution type two-stroke engine can be made bigger motor.This also is that it has bigger firing chamber, and sufficient effective institute body.When burning, make the pressure ratio that adds bigger to piston.Turn round also more flat simultaneously making big starting.
2. present motor can not provide good combustion condition.
Seven, the cylinder gas distribution type motor fuel uses extensively
Cylinder gas distribution type two-stroke engine has the firing chamber and the sufficient active combustion gas of best shape dress because of it, also can proper functioning when using other fuel.
As: using also normally starts such as liquefied natural gas, biogas, alcohol.
The use of cylinder gas distribution type two-stroke engine
Its power ratio of cylinder gas distribution type two-stroke engine is bigger, and the efficient height is simple in structure, easily manufactured, and durable in use.
It can equally with the motor of present use be installed in cylinder gas distribution type two-stroke engine on all dynamic power machines, as Transport Machinery such as automobile, tractor, train, aircraft, steamer, motorcycles.Because the power of this motor is big, service time is long, and is easy to maintenance, and many machineries can provide good conditions of service as people after using gas distribution type two-stroke engine, better create wealth for people.
