DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a component of a four-stroke internal combustion engine, that is, an internal combustion engine used in land, sea and air for vehicles, ships, aircraft, and various power sources. By adding rotational movement to the vertical movement of the piston, two strokes of suction and exhaust are performed without using a suction valve and an exhaust valve, which is a four stroke of four cycles.
The present invention relates to an internal combustion engine driven by performing stroke operations of suction, compression, combustion, and exhaust.

2. Description of the Related Art Conventionally, a four-cycle internal combustion engine has an overhead valve [OHV], an overhead camshaft [OHC], a double overhead camshaft [D
OHC], the system has been put to practical use as a power source for a wide variety of things and has brought enormous benefits to us, but the mechanism that moves the intake valve and exhaust valve has a large resistance to convert explosive energy into rotational energy. Power, the energy is not fully utilized, and the devices that operate the mechanism occupy many places in the internal combustion engine,
The configuration of the internal combustion engine main body is also complicated and large, and generates mechanical noise (such as tappet noise).

[0003]

The problem to be solved is to convert the explosion energy of the internal combustion engine body into rotational energy without resistance by improving the intake, exhaust, and system of the internal combustion engine, to make it compact, and This leads to simplification of the structure, reduction of mechanical noise, shortening of the manufacturing process, and cost reduction of the main unit.

Means for Solving the Problems The present invention eliminates the inred manifold and the exhaust manifold located at the upper part of the four-stroke internal combustion engine and the two valves and the mechanism for driving the same, and the cylinder wall has The inred manifold and the exhaust manifold are arranged in parallel on the side surface, a piston rotation guide pin is provided, the inlet and exhaust ports are dug in the piston, and a rotation groove for rotating the piston is also cut, Either make the fulcrum of the piston and the conrot be spherical, or place a universal joint at the fulcrum of the piston and the connecting rod instead of the piston rotation guide pin and the piston rotating groove so that the piston and the connecting rod rotate together, and make the fulcrum of the connecting rod and the crankshaft Has a gear wheel and a connecting ratio of 2 for the connecting rod and 1 for the crankshaft. , Whereby rotational movement is added to the up and down movement of the piston so that the piston makes one revolution while the crankshaft makes two revolutions.

BEST MODE FOR CARRYING OUT THE INVENTION The present invention repeatedly performs four cycles of suction, compression, combustion, and exhaust by rotating the up-and-down motion of an intake port and an exhaust port dug in a piston and a piston. It is an internal combustion engine that can be continuously driven. In short, in FIG. 1, the suction stroke is about to be completed by the inred manifold 7 provided in the cylinder 5 and the exhaust port and the suction port 13 provided in the piston 10. Due to the rotation guide pin 8 and the piston rotation groove provided in the piston 10, the inred manifold 7 is closed by the piston 10 while rotating upward while rotating left.
10 enters the compression stroke towards top dead center. In FIG. 2, the compression stroke is completed and the fuel is ignited by the spark plug to start combustion.
As a result, the piston 10 is pushed down while rotating to the left, and the piston 10 moves to the bottom dead center. After the combustion is completed in FIG. 3, the piston 10 rotates counterclockwise by the piston rotation guide pin 8 and the piston rotation groove 9, the exhaust port and the intake port 13 overlap the exhaust manifold 6, and the piston 10 enters the exhaust stroke, and the piston 10 dies. Head to the point. Exhaust port and intake port provided in piston 10 in FIG.
After the exhaust stroke is completed by the exhaust manifold 13 and the exhaust manifold 6, the piston 10 rises to the top dead center, and the left rotation of the piston 10 starts the intake stroke at the exhaust port and the intake port 13 and the inred manifold 7, and the piston 10 is lowered. The internal combustion engine moves while rotating leftward to the dead center, and continues to be driven sequentially and repeatedly to the stroke shown in FIG.

[0006]

As described above, it is understood that the basic mechanism is different from the conventional internal combustion engine, and that the novelty is understood. The moving resistance can be eliminated and the energy transmission loss can be suppressed, and benefits such as downsizing of the internal combustion engine, simplification of the structure, reduction of mechanical noise, shortening of the manufacturing process, and cost reduction of the main body can be obtained.
