Abstract

The invention relates to an explosive circular piston engine (A), which allows for more power to be delivered to the crank shaft (8) with lever force by further increasing the pressure generated with the explosion at the circular piston surface (2.1) by the help of a convex structured lever arm (5) connected with piston rod (5), similarly to the logic of lever thanks to its special design.

Description

EXPLOSIVE CIRCULAR PISTON ENGINE WITH LEVER FORCE Technical Field

The invention relates to an explosive circular piston engine, which allows for more power to be delivered to the crank shaft by further increasing the pressure generated with the explosion at the circular piston end by the help of a lever arm similarly to the logic of lever thanks to its design.

State of the 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 centreline of 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 connected with crank shaft, more than one planetary pinion gear positioned 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. The Objects of the Invention

On the basis of the state of the art, the main object of the invention is to develop an explosive circular piston engine; which allows for more power to be delivered to the crank shaft by further increasing the pressure generated with the explosion at the circular piston end by the help of a lever arm similarly to the logic of lever thanks to its special design.

Another object of the invention is to provide that the crank shaft rotates more strongly by transmitting the motion received from piston rod by means of the explosion occurring on the circular structured end of piston to the crank shaft via the convex structured piston rod. By this means, engine efficiency and power have been increased considerably in comparison with the counterparts.

When piston (2) is on the upper dead point and on the lower dead point, Figure 1 shows schematically the side cross-sectional view of engine (A) of the invention.

The engine (A) of the invention comprises a piston (2) having circular piston surface (2.1) and piston groove (1) with a hollow cylindrical structure in which the piston (2) moves. The piston (2) is connected with the upper end of the piston rod (3) on the first joint point (4). The piston rod (3) is jointed partly in a rotatable way to the piston (2).

The lower end of the piston rod (3) is connected partly in a rotatable way to one end of the convex structured lever arm (5) from a second joint point (6).

The other end the convex structured lever arm (5) is connected partly in a rotatable way to a crank shaft (8) from a third joint point (7). The lever arm (5) is connected with piston rod (3) from one end and is connected with crank shaft (8) from the other end. The lever arm (5) transmits the pressure occurring with the explosion on the circular piston surface (2.1) to the crank shaft (8) by increasing it similarly with the logic of lever thanks to its special convex structured design.

It is provided that the crank shaft (8) rotates more strongly by transmitting the motion received from piston rod (3) by means of the explosion occurring on the circular piston surface (2.1) in the end portion of the piston (2) to the crank shaft (8) via a convex structured lever arm (5). By this means, engine (A) efficiency and power have been increased considerably in comparison with the counterparts.
