And change, inner cylinder body 300 and outer cylinder body 400 are divided corresponding function cavity by piston 210, and it is empty that piston 210 divides inner cylinder body 300
Chamber, the movement of piston 210 front be compaction cavum (in Fig. 8, the direction of motion of piston 210 is to turn to the direction b, c, d successively from a,
And air-breathing is carried out when rotating b from a, and lighted a fire using spark plug 410 between a, b, it is compressed during turning to c from b,
Do work during c turns to d, be finally vented during d turns to a, thus complete a stroke), piston 210 is transported
Dynamic rear is air inlet cavity, and piston 210 divides outer cylinder body 400, and the front that piston 210 moves is exhaust cavity, and piston 210 is transported
Dynamic rear is acting cavity, is functional status before and after the cavity that piston 210 is inswept, realize respectively air inlet, compression, acting,
It is vented four strokes, intake process, when incision inferius is crossed in 210 acting face of piston, due to wobbler action, the end cap of inner cylinder body 300
The driven screw-casing 110 of air inlet, 120 two sides of quiet screw-casing are removed, and air inlet gradually opens wide, and mixed gas enters inner cylinder body
300, mixed gas is entered by the first end cover 310 and second end cover 320 of 300 both sides of inner cylinder body, and therefore, gas is formed pair
Claim shape spiral air flow, mist state fuel can with fresh air carry out it is secondary mix, make gaseous mixture become more uniformly, promote burning
Efficiency, when incision inferius is crossed in face of doing work after piston 210 again air inlet terminate, air inlet corner is close to 350 ° at this time, inflationtime compared with
Plunger type engine air inlet corner extends 60%, improves volumetric efficiency;It calms the anger process, beginning of calming the anger when air inlet closes to an end,
210 acting face of piston goes to point before secant, and scavenging air valve in piston 210 is opened, compressed gaseous mixture by scavenging air valve into
Enter combustion chamber, piston 210 at this moment tends to acting state, and 210 stress surface of discharge chambe piston is gradually reduced, when combustion chamber and compression
When room volume is equal, compression ratio reaches maximum value, and 11:1~12:1, (compression ratio is determined by 210 width value of piston) works as piston
210 deflation areas are calmed the anger end when going to incision inferius;Acting process, there are one overlap periods with compression process for acting process, work as piston
When ventilation axis 227 in 210 is opened, gaseous mixture enters combustion chamber, and the outer cylinder sheath inner cylinder of combustion chamber is equipped with collecting plate, outer cylinder sheath
And it sets and leads to spark plug 410 there are two groove, so that gaseous mixture touches spark plug 410 in advance, outer cylinder body 400 is equipped with three pairs
Spark plug 410, first pair of spark plug 410 are conventional ignition, and second pair and third are cold start-up auxiliary firing to spark plug 410,
When cold start-up, three pairs of spark plugs 410 are lighted a fire simultaneously, to ensure to obtain larger ignition energy in cold start-up, wait for that engine reaches
To after normal working temperature, first pair of spark plug 410 can meet ignition condition, and under engine cold state, gaseous mixture is by fire
410 igniting of flower plug, after engine operation preheats tens of seconds, collecting plate assembles the temperature that heat makes collecting plate from mixture combustion
Rapid to increase, compressed gaseous mixture rapidly gasifies after touching red-hot collecting plate, and gaseous mixture is made to be in the critical condition of burning,
Spark plug 410 is lighted a fire simultaneously, and subsequent flame front, which is lighted, constantly enters the compressed gaseous mixture in combustion chamber, and the speed of burning is remote
Higher than traditional combustion engine, burning velocity under high rotating speed is close to the velocity of sound, when collecting plate reaches rated value, the mode lighted by
Collecting plate and spark plug 410 are carried out at the same time, and realize that multi-point spark, the high pressure gas of burning push piston 210 to rotate, work as piston
When 210 acting faces go to incision inferius, piston 210 is in this corner phase, and do work volume and the effectively acting area of piston 210 for combustion chamber
The ratio between set, improve 20% combustion utilization efficiency compared with conventional engines, piston 210 continues to go to outer cylinder sheath will equipped with exhaust ports
When exhaust, acting volume at this time is 1.6 times of admission space, and in a working cycles, the corner that does work of piston 210 is reachable
240 °, combustion utilization efficiency can be improved 35%;Exhaust process, 210 acting face of piston reaches exhaust outlet when acting closes to an end, then
Piston 210 rotate exhaust outlet instantaneously open wide, 210 acting face of piston reach go forward secant point when, exhaust terminates;Air inlet and exhaust
Mouth is open, and intake and exhaust is respectively independently, is not interfere with each other;The movement of the engine is by inner cylinder body 300 and piston 210
For rotating Vortex, piston 210 drives inner cylinder body 300,331 He of the first notch end of the indentation, there of the annular sleeve 330 of inner cylinder body 300
Second notch end 332 has certain with the first set square component 230 of piston 210 and the cambered surface of the second set square component 240
Sealing contact surface makes contact surface have certain contact due to the effect of rotary centrifugal force, and to meet air-tightness, first is close
Seal 111 and the second sealing ring 121 contact with each other respectively at dynamic screw-casing 110, quiet screw-casing 120, due to sealing ring itself bullet
Property provides certain pressure, and every time with dynamic screw-casing 110, quiet screw-casing 120 at least three be in contact, compression process is
Compound seal, because compression seal is required higher than acting sealing, so inner cylinder body 300 and the compression that piston shaft assembly 010 is constituted are empty
Chamber meets confined condition, and the acting cavity that piston shaft assembly 010 is constituted with outer cylinder body 400 and inner cylinder body 300 is close using gap
Envelope, being designed with conducive to contact movement spillage of material, and reducing friction resistance is eliminated for gap, improves the reliable of mechanical movement
Property, air-tightness when can also meet acting between piston 210 and cylinder body, because of the side that the direction of gas escape is moved with piston 210
To identical, motion seal gap is met the requirements, and the speed of gas escape is then less than the speed that piston 210 moves;Piston 210 with it is interior
Cylinder body 300 is contact seal, and it is empty to move screw-casing 110, quiet screw-casing 120 and 300 two sides of inner cylinder body formation lubricating oil storage
Chamber, dynamic screw-casing 110,120 both sides of quiet screw-casing and 300 both sides contact surface of inner cylinder body therefrom obtain lubricating oil and are lubricated, quiet
The rotation of screw-casing 120 is static state, is axially movable, and moves screw-casing 110 and is fed for spiral, to keep and 300 both sides of inner cylinder body
Contact.
