The working principle that rotary-piston type working machine is used as internal-combustion engine is set forth below for embodiment 1:

As shown in Figure 3, piston 23 turns clockwise along with the first Sealing 22, and from a left side, the second Sealing 16 being positioned at below rotates counterclockwise.Piston 23 moves from intake valve 12 to block mount inlet 15, in the process of this movement, the induction chamber A (chamber between piston 23 and suction port 12) at piston 23 rear portion becomes large gradually and is drawn into induction chamber A by air from intake valve 12, and the pressing chamber B (chamber between piston 23 and the second Sealing 16) before piston 23 diminishes gradually and the air storage firing chamber that the air in pressing chamber B is compressed in piston 23 by the inlet end of gas port 25 is formed high temperature and high pressure gas, when piston 23 moves to upper second Sealing 16 place, the volume of pressing chamber B becomes minimum 0, air in pressing chamber B is compressed in air storage firing chamber by piston 23 simultaneously completely, and the piston via hole 18 at this moment going up the second Sealing 16 also just forwards block mount inlet 15 place to, opening through the outlet side of the air pipe 25 on piston via hole 18 back piston 23 when piston 23 (also can by gas by air storage mouth press-in gas-storing pipe 19 in this process, at piston 23 through after piston via hole 18, be positioned at the puff prot ejection gas in piston 23 front to expansion chamber C), plug ignition now on piston 23, combustion gas is lighted, the combustion gas of the High Temperature High Pressure in air storage firing chamber are injected in the expansion chamber C between the second Sealing 16 and piston 23, combustion gas expansion promotes piston 23 and moves to the direction of the second Sealing 16 away from side and do work, expansion chamber C in this process between the second Sealing 16 and piston 23 becomes large gradually, tail gas in the chamber formed between piston 23 and below second Sealing 16 and exhaust chamber D the second Sealing 16 is downwards promoted and is discharged from exhaust valve 14 by the complete tail gas that does work by exhaust valve 14 by piston 23 simultaneously.

Because upper and lower piston 23 is arranged symmetrically with, when being positioned at the square piston 23 of the second Sealing 16 left, top when carrying out air-breathing and pressurized gas, the piston 23 being positioned at the second Sealing 16 right, top is just carrying out doing work and being vented.So two pistons 23 circulate and carry out air-breathing in turn and compress and the process be vented of doing work in the process rotated simultaneously simultaneously, in whole process, internal-combustion engine rotates the working stroke twice that once can complete air-breathing, compression, expansion work and exhaust.

The advantage of this internal-combustion engine:

Traditional reciprocating IC engine and the compression ratio of triangle rotator internal combustion engine and expansion ratio are equal, the tail gas which results in traditional internal-combustion engine also have very high pressure and temperature and also have energy greatly not obtain utilizing the therefore thermal efficiency is low and oil consumption is high, at present at the triangle rotator internal combustion engine of application because compression ratio is little and working stroke and time short-range missile cause fuel and more can not do work so the lower oil consumption of the thermal efficiency is higher by Thorough combustion.This internal-combustion engine can change compression with the ratio expanded and makes that the expansion ratio of gas is greater than the compression ratio of gas and the thermal efficiency that improves internal-combustion engine (is equivalent to tail gas on the basis of traditional internal-combustion engine also continuing to do work by changing the distance of suction port 12 to the second Sealing 16, the pressure of the tail gas of this sample internal-combustion engine and temperature than the temperature of the tail gas of traditional internal-combustion engine and pressure low), due to this internal-combustion engine, also to have working stroke long so the thermal efficiency of this internal-combustion engine is higher.

This internal-combustion engine does not have reciprocating component, and all moving elements are all do pure circumference rotary motion, so this internal-combustion engine does not operationally vibrate the phenomenon of more not shaking, and because there are a large amount of reciprocating parts such as piston, bent axle, connecting rod so there is not eliminable high vibration and shake when working in traditional internal-combustion engine.Even triangle rotator internal combustion engine because piston neither pure circular movement vibration and shake be also not eliminable.

This internal-combustion engine does not have valve match mechanism of bent axle, connecting rod, piston ring and complexity etc. so the more simple volume of the structure of this internal-combustion engine is less, and noise in operating is lower, and manufacturing is more convenient, and cost is lower.

During the running of the parts such as traditional I. C. engine crankshaft, connecting rod and piston, extruding is each other very large so need run well between each component of lubrication system guarantee of a large amount of lubricant oil and complexity, even if with the bent axle of a large amount of oil lubrication reciprocating IC engines, connecting rod, piston, piston ring, particularly cylinder block also can heavy wear and cause leaking gas and greatly shortening working life like this.And this internal-combustion engine only has and to need lubrication between gear, and piston, neither need the seal ring of similar piston ring and so between cylinder body and Sealing and only have each other contact not extruding so almost not rub and sealing effect is better, so this internal-combustion engine seal is better, wear and tear less, because the energy of frictional loss is less, longer service life.

Triangle rotator internal combustion engine is because cylinder block and piston irregular causes its sealing effect difference and manufacture and maintenance difficult and cost is high.

In sum, this internal-combustion engine is compared with traditional reciprocating IC engine and triangle rotator internal combustion engine, among three, the working efficiency of this internal-combustion engine is larger, and the thermal efficiency is higher, and oil consumption is minimum, structure is the simplest, running is the most steadily, noise is minimum, rub minimum, sealing effect is best, mechanical power loss is minimum, cost is minimum, keep in repair more convenient, the advantages such as working life is the longest.
