The invention relates to a square piston motor with a piston having a quadrate top surface and elbow like (like v form) arcuate structure, which allows for more power to be delivered to the crank shaft by further increasing the pressure generated with the explosion at the quadrate piston end similarly to the logic of crank thanks to its design.

State of Art As it is known, engine operation logic is four-stroke and these are defined as suction, compression, ignition and exhaust, respectively. In the present engines, when fuel explodes, the piston pushes the crank shaft vertically via the piston rods and rotates the crank shaft by means of the eccentric structure of the crank shaft. The power generation in engines takes place first by converting the chemical energy in fuel to heat energy and then activating the piston by this heat energy. In a four- stroke engine, this process follows these stages:

1. The fuel and air mixture fills with outward motion of the piston.

2. The mixture is compressed with inward motion of the piston.

3. The compressed mixture is ignited in gasoline engines with a spark emerging from spark plug gap and in diesel engines combustion occurs by spraying by means of the injectors as a result of high pressure and compression. The piston is pushed out with the energy released as a result of combustion. Therefore, the crank shaft is rotated and kinetic energy is obtained.

4. During return of the piston, exhaust valve is open and exhaust gases are discharged from the piston. Thus the cycle comes the initial position and processes are repeated from the first stage.

Because the engine completes one cycle in four stages described above, this type of engines is called four-stroke engines. In the patent searching, an engine structuring having a piston design according to the invention was not been encountered. Nevertheless, some patents prepared in the same technical area are referred to below. EP2606216B1 publication numbered patent relates to a method and apparatus for timely determining the fuel injection to measure correctly the fuel injected directly into the combustion chamber of the gas-fired internal combustion engine.

TR2019/06820 numbered patent application relates to over-expanded internal combustion engine mechanism, in which the engine is adapted to output shaft by developing a simple planetary gear set, the crank shaft is movable, the expansion ratio is greater than the compression ratio and which aims to further increase the thermal efficiency compared to conventional engines. Said mechanism consists of a sun gear associated with crank shaft, more than one planetary pinion gear located around the sun gear, ring gear which the circular motion on the sun gear is transmitted with the help of planetary pinion gears, a planetary carrier in which the motion on the ring gear is transmitted and holds the outer orbit gear with the outer orbit gear centre which is offset by a distance a from the centre of the planetary gear set and functions as an intermediate gear by changing the direction of movement of the planetary pinion gears. Consequently, the presence of problems with the present engines and the inefficiency of the present solutions made it necessary to make improvements in the related art. Objects of the Invention

On the basis of the state of state of art, the main object of the invention is developing the square piston motor comprising a piston having a quadrate top surface and elbow like (like V form) arcuate structure, which allows for more power to be delivered to the crank shaft by further increasing the pressure generated with the explosion occurring at the quadrate piston's top surface at the end of the piston similarly to the logic of crank thanks to its design.

Another object of the invention is to provide that the crank shaft rotates more strongly via the piston rod by means of the explosion occurring at the quadrate end side of piston.

A further object of the invention is to provide that piston does not rub definitely with the liners while going up and down between upper dead point and lower dead point circularly in the liner since one end of piston is fixed with pin, in this way the piston will not wear out and therefore piston life is prolonged and heat is minimized.

A further object of the invention is to provide that piston rubs fully against the sides with the semi-circular motion of piston owing to its inclined ring grooves created on the piston and does not form gaps. It was provided that the piston advances in accordance with the movement in the groove in which the piston resides and without forming a gap.

Another object of the invention is to eliminate the risk of compressing to the underride because there are no plug gaps in the case that the rings wear out. Thus, the engine does not burn oil. This engine, not burning oil and not encountering overheating, will have a longer life.

The invention relates to a square piston motor (A) comprising a piston (3) having a quadrate top surface and elbow like (like V form) arcuate structure, which allows for more power to be delivered to the crank shaft (5) by further increasing the pressure generated with the explosion occurring at the quadrate top surface (3.1) at the piston (3) end similarly to the logic of crank thanks to its design.

It was provided that crank shaft (5) rotates more strongly via piston rode (4) by forming crank effect not existing in the conventional engines by means of the explosion occurring at the side of quadrate top surface (3.1) of piston (3). It was provided that the pressure generated with the explosion is transmitted to crank shaft (5) by increasing it much more with the crank effect and engine efficiency is considerably increased since piston (3) has a V like design and is fixed on the inner liner block (2) of one end of the piston (3). As it is seen from Figure la and Figure lb, square piston engine (A) includes piston (3) designed to be able to move in piston movement channel (9) located between an outer liner block (1) and an inner liner block (2). As it is seen from Figure 4a and Figure 4b, the end portion of said piston (3), which moves in the piston movement channel (9) and provides explosion, preferably has a rectangular form and the end portion has a quadrate top surface (3.1).

Also ring grooves (3.2) were created at the side surfaces of angular end of piston (3). Said ring grooves (3.2) were created with a decreasing slope from inner liner block (2) towards outer liner block (1). Since the ring grooves (3.2) formed on piston (3) are sloped, it was provided that piston (3) fully rubs against the sides at its semi circular movements and does not form any gaps. It was provided that the piston (3) advances in accordance with the movement in the piston movement groove (9) and without forming a gap. It was provided that by placing L rings (12) and ring springs (13) seen from Figure 8a and Figure 8b in said ring grooves (3.2), piston (3) rubs fully against the sides at its semi-circular movement in piston movement channel (9) and does not form any gaps. In the case that the rings wear out, because there is no plug gaps the risk of compressing to the underride was eliminated. Hence, the engine does not burn oil. This engine, not burning oil and not encountering overheating, was made to last longer.

One end of piston (3) is connected in a rotatable way on inner liner block (2) via pin, etc. passed through a piston connection hole (7). Similarly, piston (3) and piston rod (4) are connected together via pin, etc. passed through a piston rod connection hole

(8). Piston rod (4) seen from Figure 7 transmits the movement that it takes from the piston (3) to the crank shaft (5) which it connects it with crank shaft connection bearing (4.1).

As it is seen from Figure 3, an intermediate block, on which water channels (10.1) are located, and liner cover (10) were connected to the top of crank shaft (5). Water pass hole (1.4) and water recirculation hole (1.5) are located on outer liner block (1) located on the side portion of intermediate block and liner cover (10). Thus, the engine liner is provided to cool. As it is seen from Figure 9a and Figure 9b, the water channels (1.1) were formed along piston movement channel (9) on outer liner block (1). Thus, it is provided that overheating caused by the friction during movement of piston (3) is prevented. The fixing pin holes (1.2) and connection holes (1.3) were also formed on outer liner block (1) for fixing to other engine parts.

As it is seen from Figure 10a and Figure 10b, the water channels (2.1) were also formed along piston movement channel (9) on outer liner block (2). Thus, it is provided that overheating caused by the friction during movement of piston (3) is prevented.
