An internal gear 9 is provided on a side housing 15, and a half- diameter planetary gear 6 is meshed with the internal gear 9. A crankshaft 7 is directly connected to the planetary gear 6, and in association with rotation thereof, the piston 1 is reciprocated through a connecting rod 8. When the rotor 3 is rotated, an exhaust port 5 is closed, an intake port 4 is opened, and the piston 1 descends, so that fuel mixture is sucked into the operating chamber 11. When the rotor 3 is rotated by 90 deg., the intake port 4 is closed, and the fuel mixture is compressed by the ascent of the piston 1 so as to be exploded by an ignition of a spark plug 12. With the advance of rotation, the operating chamber 11 is connected to the exhaust port 5, and the piston 1 ascends, so that combustion gas is exhausted outside the operating chamber 11.

Detailed Description of the Invention (Field of Industrial Application) The present invention relates to the structure of a 4-stroke rotary piston engine, and more specifically, the present invention relates to the structure of a four-stroke rotary piston engine. It provides a 4-stroke rotary piston engine made from Ti that is fuel efficient and simple.

(Prior Art) The conventional rotary engine is a pandel type in which a rotor consisting of an inner envelope moves in a housing consisting of a trochoid curve and performs eccentric motion and two-rotation motion in combination, which causes vibrations, vibrations, etc. It is common because of its advantages such as low noise, small size, high output, and small number of parts.

However, this Wankel-type rotary engine also has a drawback in that the rotor has a large-diameter internal gear and a small-diameter rotary gear is meshed with it to obtain rotational force, resulting in large frictional resistance and poor transmission of rotational force.

The aim is to create a 4-cycle rotary piston engine that has a complete circular rotation cycle, improves combustion efficiency, and has less vibration and lower fuel consumption.

Further, an internal gear 9 is cut into the side housing 15, and a planetary gear 6 with a small diameter of 1/'2 is meshed with the internal gear 9, which revolves around the inner circumference of the internal gear 9 while rotating.

Further, a crankshaft 7 is directly connected to the planetary gear 6, and the piston 1 reciprocates through the connecting rod 8 in response to rotation, thereby forming an operating chamber.

In addition, a crankshaft 7 directly connected to the planetary gear 6 is connected to the rotor 3, and its rotation is in the same direction as the revolution of the planetary gear 6, and the piston 1 also reciprocates in accordance with the rotation, and the suction , compression, explosion, and exhaust, these four strokes are constructed in such a way that an internal gear 9 and a planetary gear mechanism are coupled to the crankshaft 7.

(Example) In Figures 1, 2, and 3 depicting the longitudinal front, rear, and side views of the engine of the present invention, 2 is the rotor housing, and the main body of the housing 2 is used to create the working chamber and the combustion chamber. The housing is completely circular with no external bulges or dents. Then, an intake boat 4 and an exhaust boat 5
In this case, a system is adopted in which a sudden report is sent to the housing 2 using RF. .

Incidentally, the spark plug 12 is the same as the conventional one.

Furthermore, the rotor 3 inscribed in the housing 2 is also completely circular. As shown in FIG. 5, the circumference 36 of the rotor 3

A piston 1 is inscribed within the working chamber 11.

Further, the structure of the head portion of the piston 1 is in the shape of an arc along the inner circumferential surface of the housing 2, and a groove is cut in the center of the head portion to form a combustion chamber.

Next, there are side housings 15 disposed on both sides of the rotor 3 . In the side housing 15,
To the outside around the output shaft 13.

A perfect circular internal gear 9 is carved, and a planetary gear 6 with a small diameter 1/2 of the internal gear 9 is engaged, and the inner circumference of the internal gear 9 is formed into a planetary gear 6.
revolves while rotating on its axis.

Furthermore, the rotation # (rotation) is achieved by directly connecting a circular wheel 14 corresponding to a crank arm to the output 1dl13, attaching the shaft portion of the crankshaft 7 to the wheel 14, cutting a horizontal hole in the wheel 14, and attaching the crankshaft to the output 1dl13. The shaft portion of the shaft 7 is connected.A bearing or the like is fitted into that portion to enable free rotation and revolution.Furthermore, the crankshaft 7 is also connected to the rotor 3.Furthermore, the output The wheel 16 directly connected to the shaft is directly connected to the center of the side wall of the rotor 3.

Further, the position where the crankshaft 7 is coupled to the rotor 3 is located outside the center of the output shaft, and a horizontal hole is carved in the side wall located toward the bottom of the working chamber 11, so that the shaft portion of the crankshaft 7 is coupled. Furthermore, bearings etc. are fitted in that part as well.

In addition, as the planetary gear 6 rotates (rotation, revolution), the crankshaft 7 also rotates in the same manner.

Furthermore, the rotation is such that the connecting rod 8 connected to the crankshaft 7 enters the piston pin 10 into the small end part, and the piston 1 is connected to the piston 1.
It reciprocates and completes each stroke of suction, compression, explosion, and exhaust in one rotation of 360 degrees, and the cycle can be reasonably continued.

Next, the operation of this embodiment will be explained.

First, let us explain based on Fig. 6, which shows the suction, compression, explosion, and exhaust strokes.
The rotor 3 rotates, and the exhaust bow 1-
5 closes, and at the same time, the intake boat opens, and Bis I・N 1
By descending, a mixed gas of gasoline and air is sucked into the working chamber 11.

The suction stroke is completed when the rotor 3 rotates 90 degrees. (c) and (d) in Figure 6. Furthermore, at the same time as the intake stroke is completed, the intake port 4 is closed by the rotor 3,
The trapped mixed gas is compressed by the rise of the piston 1 and becomes completely airtight. The compression stroke is completed when these rotors 3 rotate 180 degrees. (E) (E) in Figure 6
Furthermore, when the compressed mixed gas ignites the spark plug I2, it ignites and explodes. The combustion gas acts as an expansion force and pushes down the piston 1, and the rotation of the rotor 3 completes the explosion stroke at 270 degrees. As the rotation further progresses, the working chamber connects with the exhaust boat 5 and opens.
Piston 1 rises again. During this stroke, combustion gas is discharged outside the working chamber. The rotor 3 rotates through 360 degrees, completing four strokes each, and is a four-cycle rotary engine that repeats the same operation.

(Effects of the Invention) The 4-stroke rotary piston engine of the present invention is one or more, and includes a circular rotor 3 directly connected to the output shaft, a housing 2 formed in a perfect circle, and a working chamber carved in the rotor 3. A piston 1 is inscribed inside the rotor 3, and it reciprocates as the rotor 3 rotates, and the cycle can be rationally continued.

Furthermore, the rotation of the rotor 3 is a complete circular motion without eccentric movement, and a mechanism with smooth rotation and less vibration can be achieved.

Regarding the mechanism of generating rotational force, the piston 1 receives the explosive force of the explosion stroke and expands throughout the working chamber 11, and the yns force pushes down the connecting rod 8 and rotates the crankshaft 7.

Up to this point, it is no different from a conventional reciprocating engine, but the crankshaft shaft is connected to the rotor 3 and is further directly connected to the planetary gear 6, and its rotation revolves around the inner circumference of the internal gear 9. The revolution becomes the rotation of the rotor 3.

In other words, the force with which the connecting rod 8 is pushed down and the rotation of the rotor 3 become forces that gather together to reach the maximum expansion point, and rotational force loss is kept to a minimum and higher rotational output can be efficiently obtained. be.
