Structure of the present utility model has been made detailed description in conjunction with the accompanying drawings in preamble narration realizes the literal of technological scheme of goal of the invention, repeat no more herein.

The utility model embodiment one working principle: please refer to Fig. 1,

A. air-breathing, when cam nose turns over suction port 12 clockwise, because tappet 13 compresses cam, cam nose and body seal, a tappet 13 and a most advanced and sophisticated side space are increased, vacuum is increased, and inflammable mixture is inhaled into until going to another stile's face 3 air-breathing finishing, and inflammable mixture is enclosed in the space of tappet 3 and 13;

B. compression, behind air-breathing finishing, another cam nose is crossed tappet 13, begin compression, when compressing inflammable mixture gas pressure surpassed certain pressure, one- way valve 7,7A opened and make inflammable mixture enter firing chamber 6 and firing chamber 6A, forwarded tappet 3 compressions to until cam nose and finished;

C. expand, after compression finishes, plug ignition, gas expand and by just with firing chamber 6, the passage 15 that 6A communicates enters expansion chamber and actuating cam rotates work done, because slide block 18 sealing channels are arranged, gas can only enter expansion chamber by passage, when cam class end forwards relief opening to, expansion finishes, when spark plug 10 is lighted a fire with certain advance angle, because gases are lighted the pressure rising in the firing chamber 6, one-way valve 7 is closed, remaining a small amount of combustible gas continues to enter small combustion chamber 6A by one-way valve 7A, forwards tappet 3 to until cam nose, and spark plug 10A igniting makes small combustion chamber 7A gas be lighted expansion and rotates work done by the passage actuating cam;

D. after cam nose is crossed relief opening, gas is discharged from until another tip of cam and forwards relief opening to, exhaust finishes, this moment, firing chamber residual gas pressure was still very high, so communicate with exhaust port 16 on the end face when firing chamber 6 and 6A go to exhaust port 16, waste gas of combustion chamber is by emptying, and one- way valve 7,7A close automatically at this moment;

E. in fact, inflammable gas is sucked continuously, compresses, expands and discharge four processes is to carry out synchronously, and with regard to work done once, the work done angle was a half cycle when cam nose revolution was crossed tappet 3, in one week of work done so cam whenever circles, the two stroke engine higher than work done frequency also is twice.

The utility model embodiment two working principle is referring to Figure 13;

A. air-breathing, when cam nose turns over inlet hole 12 clockwise, because tappet 13 compresses cam 2 and seals with it, the tip of cam increases with the space of body seal tappet 13 with a most advanced and sophisticated side again, vacuum is increased, and inflammable mixture is inhaled into, until going to another tappet 3, air-breathing finishing, incendivity mixed gas are sealed in 3 and 13 the space.

B. compression, behind air-breathing finishing, another cam nose is crossed tappet 13, the beginning compressing inflammable mixture gas, after surpassing certain pressure, one- way valve 7,7A open and make inflammable mixture enter firing chamber 6 to forward tappet 3 with 6A to until this cam nose, and combustible gas all is compressed and enters firing chamber 6 and 6A.

C. expand, after compression finished, plug ignition, gas expanded and by just entering expansion chamber and the work done of actuating cam rotor rotation with firing chamber inlet communicating 23;

The cam rotation work done, because slide block 18 sealings are arranged, gas can only enter expansion chamber by passage 15, when cam nose forwards relief opening to, expansion finishes, when spark plug 10 is lighted a fire with certain ignition advance angle, because gas is lighted the pressure rising in the firing chamber 6, one-way valve 7 is closed, remaining a small amount of combustible gas continues to enter small combustion chamber 6A by one-way valve 7A, forward tappet 3 to up to cam nose, spark plug 10A igniting is lighted small combustion chamber 6A gas to expand and is rotated work done by the passage actuating cam, and (opposite side semi-ring 2 with seal up opposite side inlet 26 to 26A) is until rotating relief opening 11 when expansion working.

D. exhaust: when cam nose turned over relief opening 11, gas was discharged and is gone to relief opening up to another cam nose, and this moment, the firing chamber was disconnected by the selector valve joint, and connected relief opening 27, and the burning indoor gas is discharged from.

E. in fact, air-breathing with the compression, the process of expansion and exhaust is carried out simultaneously, and inflammable gas is inhaled continuously to be reached, compress, expands and discharge, and that is to say, four processes are carried out synchronously, when the cam nose revolution was crossed tappet 3, with regard to work done once, the work done angle was about half cycle, so cam change whenever circle with regard to one week of work done be 2 times of two stroke engine, be 4 times of 4 two-stroke engines.

The utility model embodiment three is please referring to Figure 11 Figure 12, its air-breathing → compression → expansion → relief opening working procedure is identical with previous embodiment, but manyly on the structure be subjected to cam mechanism control synchronous valve on the end face, it is fairly simple to have lacked mechanisms such as slide block, the expansion details is: the edge has just arrived the synchronous gate plate valve behind cam after compression finishes the gas igniting, the synchronous gate plate valve is subjected to the synchronous cam mechanism controls, open synchronously and make gas enter expansion chamber actuating cam rotation work done, until going to tappet 13, the synchronous gate plate valve cuts out, this moment, selector valve was opened and exhaust, and another synchronous gate plate valve is opened again simultaneously, and actuating cam rotates work done.

Another characteristics of the present utility model are that sealing is reliable, and stile's face motion along cam profile accurately, reliably.Come and the casing wall sealing by elastic force and the centrifugal force that slide plate is subjected to as some rotary engine, because slide plate has certain rigidity, so certain thickness is arranged, owing to be dot encapsulation, it is expanded, the radial force of pressurized gas (can reach hundreds of ox tons generally speaking) and its elastic force, centrifugal force offsets, and causes seal failure.Elastic force and centrifugal force can cause the too big lubricating film of other process contact stress destroyed too greatly again, so that dry grinding, the phenomenon of damaging, the utility model is at this problem, the radial force that has adopted Servocontrol device that response is exceedingly fast or mechanical positioner hang down the body generation of cooling down makes the sealing more reliable, and efficient is higher.

Embodiment four, five working principle and embodiment two, three are basic identical, do not give unnecessary details herein.
