Accordingly, the present invention relates to a rotary internal combustion engine structure capable of increasing an exhaust cycle and increasing thermal efficiency.

An automobile engine is an internal combustion engine, and internal combustion engines are a group of devices in which combustion reactants and combustion products, such as oxidizers and fuels, function as the engine's working fluid inside. . The basic components of an internal combustion engine known in the known art include an engine block, cylinder head, cylinders, pistons, valves, crankshaft and piston shaft. In general, the upper surface of the cylinder head, cylinders and pistons form combustion chambers in which fuel and oxidant are introduced to cause combustion operation. Such engines derive energy from the heat released during combustion of unreacted working fluids, such as mixtures of oxidants and fuels. This process takes place inside the engine and becomes part of the thermodynamic cycle of the device.

In all internal combustion engines, useful work arises from hot gaseous combustion products applied directly on the moving surfaces of the engine, such as the top or the crown of the piston. In general, the reciprocating motion of the pistons is transmitted to the rotational movement of the crankshaft via the connecting rods.

The internal combustion engine CI may be classified into a spark ignition (SI) type and a compression ignition (CI) type. SI internal combustion engines, such as typical gasoline engines, use sparks to ignite a mixture of air and fuel. On the other hand, CI type internal combustion engines, such as typical diesel engines, ignite the mixture of air and fuel with compressed heat.

In the engine block, the piston located at the pressure of the explosion of fuel injected in the cylinder space moves, and this reciprocating motion is changed to rotation through the crankshaft.
