Description

The technical solution concerns the field of internal combustion engines.

BACKGROUND OF THE INVENTION

The most widespread internal combustion engine is currently converting the short linear movement of the pistons into a rotary one using a crank mechanism. This conversion takes place in any internal combustion engine, ie two or four stroke, regardless of the fuel, except for the Wankel engine or internal combustion turbine.

The essence of the technical solution

It is a rotary internal combustion engine characterized in that it does not perform a short linear motion, but a rotary motion without a crank mechanism and a timing mechanism, where the cylinders and pistons rotate together with the rotor. The crank and timing mechanism is eliminated. Engine operation, in terms of piston filling and running, is two-stroke. The piston acts from to other dead center to top dead center filling and compression. And from the top dead center to the bottom dead center, expansion and exhaust take place. This single cylinder view is performed in the cam version at 1/2 turn t. j. at 180 ° over the entire turn, i.e. 360 °, one cylinder has two expansions that directly convert into rotational motion by the pressure of the gases on the rotating cylinder and piston. If the rotor has only 4 cylinders, there are 8 expansions per stroke per work stroke. Two revolutions compared to a four-stroke four-cylinder engine account for 4 expansions of a conventional engine. With a new twin engine, it's 16 expansions. For a piston rod engine, this is half the expansion, the word eight. The filling and emptying of this engine is without valves directly through the ducts on the stator of the engine - the intake and exhaust ducts, of which there may be more. The timing depends on the position of the channels and their cross-section on the stator relative to the movement and stroke of the piston cylinders, or the movement of the orifice slide, which can change the engine timing and affect engine torque and performance. This exchange of mixture, exhaust and filling takes place before and after the bottom dead center. Since the exhaust pressure has a certain force, it can be passed through

Second

turbokomresor. The engine can be switched - turbo. The filling of the cylinders with air or mixture can have a certain overpressure: 0.1 - 0.3 MPa.

The engine can operate as a positive ignition or compression ignition. The fuel can be petrol, diesel, gas or gas. hydrogen, light oils, water, etc. The motor consists of the following parts: The left housing closes the stator from the left side, it is of circular diameter, in the middle it has an opening for the bearing through which the axis of the rotor passes. It is the engine drive shaft. It is also fitted with a roller bearing of large diameter. It has a double cover. Inside it is cooled by water, on its inner circumference bears large rotor sealing ring The rotor is of circular cross-section with axis. It has openings for cylinders and pistons on its periphery. The pistons and cylinders rotate simultaneously with the rotor. The rollers can be min. 4 pcs to 16 pcs or more, depending on rotor and cylinder diameter.

The rotor is mounted in rolling bearings on its larger diameter from left and right. On smaller bearings there is also its axis. The rotor is sealed from the left and right side with rings. The individual cylinders are also sealed from above by rings against the stator, which closes the rotor between the left and right housing.

The stator is of circular cross-section (ring) and is closed from the left and right side by the left and right cabinet. The rotor is fitted with a minimum tolerance.

On its perimeter there are intake and exhaust pipes, ignition and injection system. Below the stator is an oil bath. The stator has a water jacket for cooling around the perimeter. The cam is mounted on the right cabinet and is hollow with two strokes of 180 °. The cam does not move - it is stationary, the rotor with cylinders rotates around it and the pistons with the bottom side follow the circumference of the cam which ensures the piston stroke - compression. The right axis of the rotor passes through the cam and holds the rotor shaft bearing. Either a fixed cam or piston rods which are directly connected to the pistons may be used in this engine to change the position of the pistons. The piston rods are rotatable, located on the right side of the housing eccentric to the central axis of the rotor. This gives the piston stroke and ensures control of the piston operation, by capturing the centrifugal forces that can push the pistons to the top dead center. The right housing closes the stator from the right side. It has a circular diameter in the middle has an opening through which the axis of the rotor that drives the engine accessories Oil pump, water pump, altrenerator, compressor and others. The large hollow cam has an eccentric inside. The cabinet has a double cover and is water cooled. In the inner circumference is mounted a large diameter rolling bearing in which the rotor rotates.

From outside and inside the bearing is of smaller diameter for the rotor axis In its inner circumference bears a large axial sealing ring of the rotor

Third

The advantage of the new-generation rotary internal combustion engine is the elimination of the technical operation, the conversion of the reciprocating linear motion to the rotary one by means of the crank mechanism and thus the frictional losses, especially pistons at a certain angle. , valves and other parts of the timing mechanism. This also reduces friction. A further advantage of this engine is that it is mixed or fueled, and that the combustion and ignition or exhaust does not occur at one point above the cylinder because the piston cylinder moves relative to the stator and thus does not undergo thermal stress at only one point. like a classic engine. Another big advantage is its good balance and hence the running of the engine without damping and oscillating forces, even balancing shafts are not necessary. Next, it's simplicity - fewer parts.

Another advantage is the large number of working cycles - expansion and thus increased power and efficiency and economy of the engine. Furthermore, that the engine can operate at full power or partial, which can easily be controlled by fuel injection, at a lower load, this means that the control unit will allow some cylinders not to be filled and thus ensure economy. Its high power and low friction losses allow it to work on a lean mixture by spreading and controlled multi-point fuel injection against the movement of the rotor cylinder and stroke of the piston with respect to engine load and speed. After further development of the engine also advantageous values of exhaust gases in the exhaust gases.

DETAILED DESCRIPTION OF THE INVENTION

The essence of the invention is a rotary internal combustion engine which does not perform a short linear motion, but a rotary motion without a crank mechanism and a timing mechanism where the cylinders 9 and the pistons 10 rotate together with the rotor.

5. Crank and timing mechanism is eliminated. The operation of the engine, with respect to the filling and operation of the piston 10, is two-stroke. The piston 10 acts from bottom dead center to top dead center filling and compression. And from the top dead center to the bottom dead center, expansion and exhaust take place. This action with respect to one cylinder 9 is performed on the cam version at 1/2 turn t. j. 180 ° for the whole turn, i.e. 360 °, one cylinder 9 has two expansions that directly convert into a rotary motion by the pressure of the gases on the rotating cylinder 6 and the piston 10. When the rotor 5 has only 4 cylinders 9, there is one turn 8 expansion - working strokes. Two revolutions compared to a four-stroke four-cylinder engine account for 4 expansions of a conventional engine. With the new 2-speed FM engine, it's 16 expansions. In an engine with piston rods 8, this is half the expansion, the word eight. Filling and emptying of this engine is directly via channels 12.13 without valves. which are on the stator 6 of the engine - an intake 12 and an exhaust 13 channel, of which there may be more. The timing depends on the positioning of the channels 12.13 and their cross-section on the stator 6 relative to the movement and stroke of the piston cylinders 9 or the movement of the shutter-diaphragm, which can vary the engine timing and affect engine torque and performance. This exchange blends, exhausts and filling sakonápred and behind the bottom dead center. Since the exhaust pressure has a certain force, it can be passed through the turbocharger. The engine can be turbocharged. The filling of the cylinders 9 with air or mixture can have a certain overpressure: 0.1 - 0.3 MPa.

The engine can operate as a positive ignition or compression ignition. The fuel can be gasoline, diesel, gas, resp. hydrogen, light oils, water, etc.
