Description
Liner Type Internal Combustion Engine
Field of the Invention
The present invention relates to a liner type internal combustion engine that operates with four-stroke gasoline or diesel oil.
The present invention particularly relates to a liner-type internal combustion engine that comprises a liner piston, a cap fixed to the engine upper block on the rings, and a rack liner located between the engine block and the liner piston.
State of the Art
In the internal combustion engines, there are piston and ring shaped sealing rings with cut mouth and scraper rings on the piston. This system is located in a liner and transforms it into mechanical energy by benefiting from the pressure occurred as a consequence of the combustion of the fuel. As soon as the engine is started, there is friction between the rings and the engine liner. The liners and segments expand by heating with the effect of this friction. Particularly, since the rings have cut mouth, opening is observed in the cut area and thus this leads to pressure losses at all times and reduces the efficiency of the engine.
The piston is connected to the connection rod so as to transform the linear motion into circular motion in the internal combustion engines. The connection rod is also connected to the crankshaft. The crankshaft axis is also referred to as an axially run out shaft. During up-down motion of the piston, connection rod continues its progress in a manner such that it can move at certain angles according to the offset of the crankshaft. Thus, the force applied by the piston will change throughout the axis of the connecting rod depending on the operation angles of the connecting rod. This leads to the contraction of the piston in the liner, thus preventing the piston from operating in a linear direction, reducing the efficiency of the engine. Furthermore, it reduces the economic life of the engine by making permanent damage in the engine liner and piston due to the contraction.
The following application is encountered in the literature in terms of the subject matter.
European patent application numbered EP3114336 (B1) relates to a compression engine with four-stroke internal combustion, pre-stage cooling. A four-stroke internal combustion engine has a property of a single or multi-stage precooled compression that provides control of the temperature and pressure of the air entering the combustion cylinders strictly, therefore a much higher compression ratio and pre-ignition compression pressure can be obtained before the fuel-air mixture approaches the automatic ignition threshold. This design can burn any type of fluid hydrocarbon fuel in a knockless manner, since it can effectively arrange and adjust the maximum pre-ignition temperature of the fuel-air mixture. This four-stroke engine generates an equivalent or higher power and a higher efficiency with a smaller and lighter engine by means of its relatively high compression ratio compared to a standard four-stroke engine. However said invention is not a liner type motor.
As a result, due to the abovementioned disadvantages and the insufficiency of the current solutions regarding the subject matter, a development is required to be made in the relevant technical field.
Brief Description of the Invention
The present invention is related to liner type internal combustion engine which fulfills the abovementioned requirements, eliminates all disadvantages and brings some additional advantages.
The main aim of the invention is to minimize the pressure losses and the contractions between the piston and the liner in the internal combustion four-stroke gasoline or diesel engines.
An aim of the invention is to eliminate pressure losses caused by the rings with cut mouth in the prior art systems by placing uninterrupted (with uncut mouth) rings and ring holders on the cap of the liner type engine.
Another aim of the invention is to provide a more stable linear movement of the liner piston without contraction, by means of the gears and the rack liner on the liner piston, thus to extend the economic life of the engine and to increase the efficiency of the engine.
In order to fulfill the abovementioned aim, the inventive liner-type internal combustion engine comprises a liner piston, a cap fixed to the engine upper block on the rings, and a rack liner located between the engine block and the liner piston.
The structural and characteristic features of the present invention will be understood clearly by the following drawings and the detailed description made with reference to these drawings and therefore the evaluation shall be made by taking these figures and the detailed description into consideration.

Detailed Description of the Invention
In this detailed description, the inventive liner type internal combustion engine (1) is described only for clarifying the subject matter in a manner such that no limiting effect is created.
The present invention relates to a liner type internal combustion engine (1 ). Said engine (1) is four-stroke and operates with gasoline or diesel.
The inventive liner-type internal combustion engine (1) comprises a liner piston (10), a cap (20) fixed to the engine upper block on the rings, and a rack liner (30) located between the engine block and the liner piston.
The liner piston (10) is a movable mechanism that performs linear motion by performing the intake, compression, ignition and exhaust processes in four-stroke engines. There are four movable gears and cooling fins on the inventive liner piston (10).
According to a preferred embodiment of the invention, cap section (20) consists of intake valve, exhaust valve, fuel injector, and spark plug and ring holders. Said cap (20), has a mechanism that is located on the sealing ring and scraper rings and consists of ring holders so as to hold these rings. Preferably, there are rings with uncut mouth and ring holders on the cap section (20) . Therefore, pressure losses can be eliminated.
According to a preferred embodiment of the invention, there are four racks on the rack liner (30). This part is an element fixed to the engine block.
Since pressure losses compared to internal combustion engines are eliminated, the engine will draw the air-fuel mixture into the combustion chamber during the period of intake. A higher compression ratio will be obtained during the compression period and pressure losses will be eliminated during combustion period. It will provide more burnt gases to be removed from the combustion chamber during the exhaust period. In this case, the engine is provided to operate with less fuel and higher efficiency.
The piston axis and the cylinder axis do not operate in the same direction due to the wears based on friction and the variable load on the connection rod after a certain period of operation in the internal combustion engines and thus leads to the contraction of the piston. As a consequence of the interworking of the gears on the rack liner (30) and the liner piston (10), this problem has been eliminated and the system has been operated in a
more stable manner, thus the operating life of the engine is increased and the engine operates more efficiently.
