(as distinguished from a four-stroke rotary engine with a triangular rotor that rotates approximately in a figure 8).

The working principle is as follows: in the intake stroke, an intake valve (14) and an exhaust valve (S) are opened, compressed air generated by turbocharging or mechanical supercharging enters a cylinder (M) through the intake valve (14), blows an inclined air passage through a whistle through the exhaust valve (S), enters a rotor cavity (P), and enters a main fuel chamber (15) through the inclined air passage blown by the whistle, when the air pressure value reaches a set value (set according to oil products), the exhaust valve (S) is switched and closed by a communicated air passage in the cylinder (M) and a rotor shell (J), so that the cylinder (M) and the rotor shell (J) are separated and isolated to form two independent spaces, the cylinder (M) is used as a fire leading space, a cylinder inner direct injection fuel device (2) arranged on an upper end cover of the cylinder (M) provides theoretical mixed gas or approximate theoretical mixed gas, and is ignited by an ignition device (1) arranged on the upper end cover of the cylinder (M), the diesel oil is ignited by compression ignition (the gasoline is ignited by ignition mode), and flame is specially produced; the exhaust valve (S) is opened, the rotor cavity (P) in the rotor shell (J) receives flame generated by the cylinder (M), and the flame is blown to open fire conveyed by the inclined communicating air passage through the exhaust valve (S) through a whistle to ignite combustible lean mixture gas supplied by the main combustion space rotor cavity (P) through the in-cylinder direct injection fuel device arranged in the main fuel chamber (15) to perform combustion work.

Shape characteristics of the rotor: the rotor is provided with a smooth arc surface protruding forwards in the forward direction of rotation, so that the resistance is minimum, the reverse direction, namely the back surface, is an arc surface and two planes AB and CD vertical to the tangent line of the circumference of the rotor, the maximum tangent line moment of forward rotation is borne, the surface adjacent to the side surface of the rotor shell is a smooth arc surface, and the two end surfaces of the rotor are planes; such as an S-shaped rotor (T) (e.g. T in fig. 3), a three-single wing rotor (e.g. T in fig. 1), a double-S vertical rotor (e.g. T in fig. 7), the rotor (T) divides the rotor chamber into two, three, four, respectively, which have the same shape, and synchronously and simultaneously operate, and the volumes of the rotor accommodating chambers (P) in the same rotor (T) are equal.

The lubricating oil channel is arranged on the rotor shaft center: the oil conveying pump conveys the engine oil to the rotor shaft center and is connected with the oil seal groove in the radial direction (side surface) of the rotor through a small hole; the centrifugal force generated by the rotation of the rotor, the engine oil thrown into the oil seal groove is fast and slow along with the rotating speed, the oil supply amount is automatically increased and decreased, the proper amount of oil is supplied, and the lubrication is reliable; the adjacent area of the rotor and the side surface of the rotor shell is large, the radial air-oil seals are arranged in multiple ways (as shown in figure 5), and the adjacent rotor cavities (P) are sealed reliably and tightly in air tightness without burning engine oil. 1. The end face of the rotor is close to the edge for one circle, a corresponding linear and arc-shaped air seal is arranged, and the air seal is closely contacted with the end face of the rotor shell by lining elastic steel bars (not shown).

2. The oil seal (5) on the end face of the rotor is arranged as the oil seal (5) shown in figures 1, 3 and 7.

3. The gas and oil seals on the radial (side) of the rotor are similar to cuboids, the cross section is similar to quadrangles, and the outer circle surface of the section adopts a barrel-shaped surface, namely a convex arc shape, so that the gas and oil seals can slide through the exhaust port and the whistle-shaped gas channel opening when the rotor rotates; for example, S-shaped rotors (refer to fig. 5) are arranged as shown by air seals (4, 3) and oil seals (6, 10) in fig. 5, fig. 5 is a rotor side surface of a circumferential rotor type internal combustion engine, radial air and oil seals represented by the S-shaped rotors at a rotor wing part are sequentially arranged in a clockwise direction from front to back according to a group of the air seals (4), the air seals (3), the oil seals (6), the oil seals (10), the air seals (4) and the air seals (3), two groups of the three types (two groups of the S-shaped rotor end surfaces, three groups of the three single-wing-shaped rotor end surfaces and four groups of the radial air and oil seals at the double-S vertical-shaped rotor end surfaces) are arranged in the same way; three small oil holes are arranged in a groove corresponding to the oil seal (6) and communicated with a lubricating oil channel at the center (O) of the rotor shaft, and as shown in figure 6, the lubrication is reliable.

As shown in the fig. 1, 3 and 7, oil leaks from the axis of the rotor through an oil seal groove corresponding to an oil seal (5) on the end face of the rotor, and centrifugal force generated by the rotation of the rotor is thrown into the oil seal groove instead of being directly sprayed into a rotor chamber, so that oil burning is avoided, and the lubrication is reliable.

6. The three small oil holes arranged in the oil seal groove corresponding to the oil seal (10) in fig. 5 are the same as the oil seal groove corresponding to the oil seal (6) in fig. 6, but are not communicated with the central oil passage of the rotor shaft, and are blind holes, so that the oil seal plays a role in storing and storing redundant engine oil.

Common characteristics of rotor end face oil seal: the oil blanket on rotor (T) terminal surface, hugs closely for rotor axle center (O) near-end, constitutes certain automatic fine setting along with wearing and tearing and can correspondingly reduce the geometry, to axle center (O) distal end radiation, extend to the scheme of arranging that adjoins the rotor shell, include: two oil seals (5 in figure 3) on the end face of an S-shaped rotor (T) are bent and spliced into a spoon shape at the near end of a rotor axis (O) to be meshed with each other, radiate towards the far end of the axis (O) and extend to be adjacent to a rotor shell; 2. three oil seals (5 in figure 1) on the end face of the three single-wing rotor (T) are closely attached to the near end of the rotor axis (O) to form a triangle, radiate to the far end of the axis (O) and extend to the adjacent rotor shell; 3. four oil seals (5 in figure 7) on the end face of the double-S vertical rotor (T) are tightly attached to the near end of the rotor axis (O) to form a quadrangle, radiate to the far end of the axis (O) and extend to the adjacent rotor shell.

The rotor end face oil seal has the functional characteristics that: the path of the far end of the rotor end face oil seal is longest, the far end of the oil seal is worn firstly, after the oil seal is worn with the inner wall of the side face of the rotor shell, the far end of the oil seal can slide and extend slightly to the rotor shell automatically under the action of the centrifugal force of the rotation of the rotor, the end close to the axis (O) correspondingly reduces the geometric shape, the geometric shape which is spliced by the end close to the axis (O) is basically kept to be similar to the original spliced geometric shape when the rotor rotates anticlockwise, the reverse thrust generated by air pressure enables the ends close to the axis (O) of the oil seal to be mutually attached, the spoon-shaped occlusion area, the triangular area and the quadrilateral area which are spliced by the end close to the axis (O) are movably connected, conditions are created for supplying engine oil at the axis (O) of the rotor, the wear allowance reserved for prolonging the service life of the oil seal is the symbolic design for replacing the oil seal, the oil seal needs to be replaced, and lubrication and sealing are ensured.

3. The outlets of the air passage for communicating the cylinder (M) with the rotor shell (J) and the air passage for communicating the main fuel chamber (15) with the rotor chamber are all in whistle-shaped inclination, which is beneficial to generating rolling vortex, accelerating the propagation speed of combustion, gas and flame, improving the combustion and improving the economical efficiency.

The cylinder can reliably ignite, the rotor can efficiently do work, and the cylinder and the rotor are skillfully integrated and complement each other. (the supercharging technology is mature, and the details of the turbocharging and the mechanical supercharging are not described in detail below).

The internal combustion engine with a circumferential rotor type is characterized in that except for a single cylinder (the generated instantaneous torque is the torque generated by a single rotor cavity (P)), the double-cylinder, three-cylinder and four-cylinder types of the internal combustion engine are synchronously performed in the working process, the generated torques can form superposition, and the instantaneous torque applied to a rotating shaft is also the superposed torque. The camera selects a mute vortex air compressor, a piston air compressor, a screw air compressor and a sliding vane air compressor, and a mechanical supercharging device is used for increasing the air density of a cylinder and a rotor cavity (P) and improving the power performance of the rotary engine.

The rotor directly drives the rotating shaft, all the rotating shaft is rotating torque, the kinetic energy conversion rate is high, the energy loss is less, the number of components is less, and the failure rate is reduced. The shape of the rotor is fixed, in the power stroke, the rotor rotates, the volume of the rotor cavity (P) is unchanged, and the rotor cavity (P) is subjected to constant volume combustion. (in the traditional piston engine, the piston descends in the power stroke, the volume is gradually increased from the top dead center to the bottom dead center, and the volume of a triangular rotor engine is also similar to the volume.

Corresponding grooves are arranged on the end surface and the side surface of the rotor, so that gas and oil can be conveniently sealed and embedded into the grooves; the oil seal on the other end face of the rotor is arranged like a plate-turning on the rotor.

The same phase rotor shaft is provided with a corresponding number of cams, so that the H-shaped direct current electromagnetic relay manages the ignition of the high-voltage electric control spark plug (1) and the oil injection of the high-voltage direct injection fuel nozzle (2); the ignition device (1) and the in-cylinder direct fuel injection device (2) are arranged on the cylinder (M), the in-cylinder direct fuel injection devices of the main fuel chamber (15) are matched with the rotor to operate, and the intake valve (14) and the exhaust valve (S) are simply and accurately opened (when the circuit is disconnected, the spring automatically returns and closes); the electromagnetic relay is shielded by a metal shell, so that electromagnetic mutual interference is prevented.

Concentric circumference rotor engine: the whole process of pressurization (vortex or piston type pressurization is selected according to the variety of fuel oil) is participated, the rotor rotates for a circle anticlockwise (or rotates clockwise, for example, the back of the rotor rotates) by taking the center (O) of the rotor shaft as the center of a circle, and a working cycle is completed through three strokes of air intake, work application and air exhaust. The working efficiency is high, and the working times of the single rotor rotating for one circle are respectively as follows: the S-shaped rotor single cylinder does work for 2 times, the S-shaped rotor double cylinder does work for 4 times, the three single wing does work for 9 times, and the double S vertical type does work for 16 times (the working efficiency is high, and is 5 times of that of a triangle and more than 1 time of a single rotor, and is 8 times of that of a four-cylinder four-stroke piston type).

The cylinder (M), main fuel room (15) and the intercommunication air flue that the rotor holds chamber (P), all design for whistle form slope air flue: as shown in fig. 9, 12, 15 and 18, the communicating air passages of the air cylinder (M) and the inner rotor cavity (P) of the rotor shell (J) and the exhaust valve (S) with the property of controlling the switch are all parallel to the tangent of the inner diameter of the cylinder circumference to form an outlet, the caliber of the air passage is smaller than the radius of the cylinder circumference, and the belly is small.

The machine has the advantages of a whistle-shaped inclined air passage:

Thereby prolonging the service life of the cylinder (M) and the accessories, the air passage, the main fuel chamber, the rotor and the rotor shell thereof, and reducing the maintenance cost.

5. The whistle-shaped inclined air passage enables compressed air, combustible mixed gas and flame in the cylinder to generate vortex, and is beneficial to flexibly arranging the spark plug (1), the oil nozzle (2) and the intake valve (14) on the cylinder wall in a proper range, so that the appearance is compact, the space is saved, and the installation and the application are convenient.

6. The concentration of the mixed gas in the cylinder (M) and the main fuel chamber (15) is higher than that of the rotor cavity, and HC and CO compounds can be generated correspondingly during combustion; nitrogen oxide (NOx) is easily generated in the rotor cavity (P) under the oxygen-enriched environment, and nitrogen is easily generated in the air under the non-pure oxygen environment; in each exhaust stroke, HC and CO compounds are discharged from the ignition space cylinder (M) or the main fuel chamber and enter and reduce nitrogen oxide (NOx) generated in the rotor cavity (P), so that pollutants in the tail gas can be reduced to the maximum extent (equivalent to an exhaust gas recirculation system with an emission reduction system similar to a piston type internal combustion engine).

(for example, in the conventional piston type diesel engine, the combustion process of the diesel engine is divided into an ignition delay period, a fast combustion period, a slow combustion period and a post combustion period, and the volume is increased continuously due to the limitation of the piston in the cylinder on the upper and lower dead points, so that strong knocking sound, rough operation, poor combustion, power reduction and black smoke in exhaust gas can be generated). The high-pressure fresh air is guided by the whistle-shaped inclined air passage to quickly form vortex, the atomized fuel is directly sprayed into the cylinder to be quickly mixed, the rotor rotates in one direction without turning back, the volume of the rotor accommodating cavity (P) is not increased in the combustion process, and the constant-volume combustion is realized.
