Referring to Fig.1, it is preferred that the oil-recovery tank 42 of compression cylinder casing wall 112 is connected to gas distributing chamber 3 to realize to gas distributing chamber 3
The lubrication of the equal components of interior cam 32, the oil-recovery tank 42 are back to after gas distributing chamber in fuel tank 41.
Serpentine swing arm lubrication groove 44 is equipped in swing arm piston 14, after 44 head end of swing arm lubrication groove extends to working end 141
End, the rear end of working end 141 refers to the side of swing arm piston 14, the side between hinged end 142 and working end 141, because
And the head end of swing arm lubrication groove 44 avoids the region burnt into working cylinder, while working cylinder casing wall can be lubricated
114.The end of swing arm lubrication groove 44 extends to the hinged place of swing arm piston 14, scrapes 43 head end of deep-fried twisted dough sticks, 14 hinged place of swing arm piston
It is sequentially communicated respectively by oil circuit between shaft 1；For swing arm piston 14 during rotation, serpentine swing arm lubrication groove 44 is logical
Crossing the turning point effect of serpentine makes oil lubrication swing arm piston 14 and working cylinder casing wall 114.
114 surface of working cylinder casing wall is equipped with oil return line 45 along 1141 lower section of the first protrusion to fuel tank 41, and oil return line 45 is used
It is recycled to fuel tank 41 in making 11 circumferential surface of the first turntable and the lubricating oil of working cylinder contact surface.
Referring to Fig.1 0, oil return line 45 includes several " V " font oil circuits 451, and " V " font oil circuit 451 is located at working cylinder cylinder
" V " head end on 114 surface of wall, " V " font oil circuit 451 extends respectively to working cylinder side wall 112, cylinder sidewall 111, each " V "
" V " the word bottom end of font oil circuit 451 is sequentially communicated by oil circuit.Lubricating oil between swing arm piston 14 and compression cylinder is not due to
Recycling can be formed on compression cylinder casing wall 115, thus lubricating oil and compressed air can pass through compression cylinder gas outlet 120 and enter
Door 116 of calming the anger is stored up, thus compressed air is filtered by machine oil blocking apparatus 21.
The operation principle of the present invention：By external force rotating shaft 1, the rotation of the second turntable 12 is driven, compression cylinder is second
Turntable 12 completes the process of compressed air during rotating, while the process of compressed air, extraneous air can pass through
Compression cylinder air inlet 119 enters compression cylinder, compressed air from compression cylinder gas outlet 120 by machine oil blocking apparatus 21 into
Enter air inlet pipe 1168,；At the same time, under the action of cam 32, the effect of hydraulic stem 35, pushing meanss 38 is passed sequentially through, is made
It obtains the opening of valve disc 1164 and stores up door 116 of calming the anger, atomizer 1169 sprays mist of oil, and mist of oil and compressed air enter working cylinder together
Interior, storage is calmed the anger after the closing of door 116, and mist of oil and compressed air are in the confined space of working cylinder, swing arm piston 14 at this time
It is combustion chamber with the enclosure space that working cylinder is formed, after spark plug 117 is lighted a fire, since the instancy of combustion of fuel oil generates high pressure,
Swing arm piston 14 is pushed to rotate, when swing arm piston 14 goes to exhaust outlet 118, swing arm piston 14 is formed with working cylinder at this time
Enclosure space be operating room, the rear-swing arm piston 14 of the exhaust gas exclusion in working cylinder is gone to initially by exhaust outlet 118
Position completes a swing circle.
When fuel is diesel oil, atomizer 1169 cannot be located at storage and calm the anger in door 116, can be located at the attached of spark plug 117
Closely, that is, it is located on working cylinder casing wall 114, and must be arranged in combustion chamber.
Angle a, angle are formed between the rotation center of rotating wheel 352 and the line and hydraulic stem 34 of the rotation center of cam 32
When degree a is bigger, storage is calmed the anger, and 116 shut-in time of door is shorter, and opening time is longer, and the opening time is longer.Because storage is calmed the anger, door 116 exists
The later stage of closing will appear combustion chamber just drops phenomenon, and the action for storing up door 116 of calming the anger is suitble to slow open suddenly to close to reduce decompression now
As occurring.When rotating speed is high, when combustion chamber is formed it is preceding when, i.e. storage calms the anger door 116 when completely closing, and plug ignition suitably carries
Before.
In this period, the volumetric ratio of combustion chamber and operating room is 1:30 or more, and reciprocating-piston engine only has 1:8
To 1:11, for example, when maximum pressure is 4.5MPa after reciprocating-piston engine burning, pressure is up to 0.5MPa after exhaust.And this
When maximum pressure is all 4.5MPa after the engine combustion of embodiment, and pressure at expulsion only has 0.15MPa or lower, exhaust wave
The power of expense only has 10 hereinafter, while with more high thermal efficiency, decreases the discharge of noise.
In order to adapt to different situations job requirement, accelerate air accumulator 22 into the gas flow energy of working cylinder by control
The operational requirements for meeting different rotating speeds can have for the ease of the startup of engine first to accelerating air accumulator 22 first to preheat
Body, accelerating to be equipped with electric preheater in air accumulator 22.
In order to eliminate the centrifugal force that swing arm piston 14 generates in rotation process, it is necessary to be done at balance to swing arm piston 14
Reason.For example, can be by the quality of increase hinged end 142, that is, increasing the mode of gravity improves.
In order to improve mixed gas burning velocity of the engine in high speed, it is necessary to be arranged two or more
Spark plug 117 is lighted a fire, which is not afraid of detonation, is more desirable to obtain detonation on the contrary.
As shown in figure 14, XY camber lines are the contact surface of top land and compression cylinder casing wall 115, working cylinder casing wall 114,
Z points are the hinge joints of hinged end 142, and O points are the center of rotation of the first turntable 11 and the second turntable 12.When X points and R points overlap
When, the Y points of generation are first Y point, and second Y point is generated when first X point reaches the 1 Y points, are revolved in swing arm piston 14
During turning, several Y points are sequentially generated, it is working cylinder casing wall 114 and compression cylinder casing wall that each Y points, which are formed by path,
115 shape.
In conclusion the present invention has the following advantages：
1. the thermal efficiency is high；
2. it is small, it is compact-sized；
3. it is simple in structure, facilitate repair；
4. environmentally protective；
5. accelerating fast；
