KOGLEN- A Rotating Internal Combustion Engine
Fundamentally, the engine is designed to provide between 20 and 150 horse power, for light aircrafts, ultralights, machinery and mechanical equipment.
This rotating engine has substantial advantages in percentages of efficiency- therefore the fuel consumption relatively to the output is low, the weight of the engine is very light and the momentums are very big, the number of parts comprising the engine is immeasurably smaller than in comparable engines and the Koglen engine is easier to cool (less fuel turns to heat).
The Koglen engine is fueled by liquid or by gas, using the method of carburetion or direct fuel injection to the combustion cell, with the option of electronic or magneto ignition.
The compression operations and work are balanced, which enables balanced powers, less friction and less wear, therefore the engine has a longer life and maintenance is minimal.
In summation, a cheaper, more efficient, stronger engine ensuring good working order for many hours of work.
Engines under development:
An engine for very high pressure with new combustion methods.
A Rotating engine for heavy fuel with preliminary ignition only, (Like in a jet engine) for great horse power output.
Field of the invention
The present invention relates to a rotating internal combustion engine.
More particularly the present invention relates to rotating internal combustion engine that executes on each rotation of the engine four-ignition operations.
Background of the Invention
There are different combustion engines that work on pistons as well as rotational engines with internal combustion such as a Vankle engine.
One of the problems in existing engines is a problem of a relatively low momentum force; the solution offered in rotational internal combustion engines is that it is not necessary to turn linear motion into rotational motion as in piston engines.
In engines with rotational internal combustion, the energy produced in comparison with piston engines is relatively higher considering the amount of gasoline put in, so actually they are more efficient.
Other objects and advantages of the invention will become apparent as the description proceeds. The object of the present invention is use of a rotational internal combustion engine comprised of a relatively smaller amount of parts, relatively smaller size, greater force and momentum, lower wear and friction and higher efficiency.
Summary of the Invention
The present invention relates to a rotating internal combustion engine, which enables higher efficiency, low weight; low wear, economizing on gasoline, lower number of parts, lower cost. The combustion engine described in the present invention enables high efficiency amongst other things due to the low friction during its operation.In the combustion engine described in the present invention the main components that come in contact with the internal combustion do not have friction during the rotation since there is a small gap between them that prevents friction.
Basically, the rotating internal combustion engine according to the present invention executes four ignition operations during each rotation. This characteristic enables the engine to produce greater momentum force relatively to other engines.
Since while the engine is operating there are two simultaneous combustion points from two different directions. Strong pressure is not applied to the bearing and on the main axis and wear of these parts diminishes significantly.
It is preferable that the rotating internal combustion engine be cooled by water and oil or air and oil. If the engine should be cooled by air it is preferable that it would have suitable cooling ribs.
According to one of the preferred embodiments of the rotating internal combustion engine will be comprised of a turbine and moving wings that enable the change of the volume of the combustion cell. According to a different preferred embodiment the main cogwheel will be permanently connected to the body of the engine in a stiff manner that will not enable it to rotate, and around it two cogwheels will rotate that are connected to the turbine and move the turbine wings in and out in the combustion cell.
The principle of operation of the present invention:
When the turbine rotates, a mixture of gasoline and air to the combustion cells.
When the wings are at approximately 30º from the zero line there is an electric spark that ignites the mixture, and at the same time the rotating valve closes and high pressure is created which causes rotational movement and extraction of the gases from the last phase.
The internal combustion engine according to the present invention also has a compressor used to insert a mixture of compressed air and gas to the combustion cell; the general structure of the compressor is similar to the general structure of the engines internal combustion cell.
According to the present invention a distributor is connected to the central axis of the rotating internal combustion engine in order to distribute the electric spark to the igniters in the combustion cell while the engine operates. Rotational valves are also connected to the central axis between the compressor and the combustion cell.
When the valve is in open mode it enables the mixture to enter the combustion cell, when operational the valves close so that the pressure created during operation does not return to the compressor.
A dual oil pump is also connected to the central axis, which creates oil pressure used to flow the hot oil from the engine into the oil-cooling radiator.
The pump is also used to spray oil on the moving components of the engine oiling them to reduce friction.
A rotor engine
An internal combustion rotor engine comprised of a central turbine and a compressor on the engines central axis, receiving a mixture of gasoline mixed with air performs a compressing operation.
After the compression operation, ignition takes place, the gasoline burns, and high pressure is created which rotates the turbine with great force.
In each rotation of the turbine clearing of the combustion gases from the previous operation also takes place.
In each rotation of the engine four ignition operations take place; the engine has very great momentum, small dimensions relatively to the engines force, low weight, the engine is 10% more economizing than existing engines types of the same scale.
The number of engine components is substantially smaller than corresponding engines and the planned wear is minimal, the cost of a hundred horsepower engine is approximately 75% of a corresponding engine of different methods. The cooling of the engine is easier than that of corresponding engines due to greater efficiency.
Gasoline
The engine may receive gasoline in three principle methods:
1 A carburetor on the manifold
2 Injection into the manifold
3 Direct injection into the cylinder
The air ratio is identical to that of corresponding engines when the mixture is compressed in the compressor by pressure that does not cause detonation (The pressure is regulated by a special valve).
In the case of direct injection to the cylinder the air pressure in the compressor can be increased (by adjusting the valve), the efficiency and capacity of the engine will increase.
If an injection system to the manifold is planned the injection may be adapted using the ignition adaptor.
Ignition
The engine has various possibilities of ignition which include all known methods of ignition including using an old school distributor, electric ignition using a module or magneto (for engines designed for aircrafts) which is put into motion from the central axis instead of an ignition adaptor.
Oiling system
The engine is comprised of two oil pumps located on one axis and are put into motion from the engines central axis.
The oiling method is pressure and spraying, the spraying cools the internal components of the engine and is cooled by a special radiator.
Cooling the engine
The engine has various possible methods of cooling, either cooling with air and oil or cooling with water and oil.
When cooling with air the encasement receives a flow of air from a central fan and the inside of the engine is sprayed with oil that goes to the external radiator.
When cooling with water the encasement has water channels for the water to flow through and through the water pump to the radiator and the flow of oil is also into the radiator using special pipes.
Engine start-up
The engine start –up is done by a conventional starter on a cogwheel that is located on the axis, the central axis.
Electric charge
A conventional alternator implements the charge.
