The invention is related to the combustion engines with internal combustion and it deals with a substantial change in terms of securing and realization of actions in the processes of the piston combustion engine.
Piston petrol engines and diesel engines, as types of combustion engines, are thermal engines, which transform the energy released by explosion and combustion of the fuel into mechanical energy. In this process, the transformation of the chemical energy into mechanical and thermal energy by combustion is a direct moving medium. A change takes place in series of consequent actions, and it consists of preparation and transfer of the fuel, fuel mixture or air, in its compression, in the initiation of the ignition impulses, in the expansion of the combustion products, to which the exploitation of the generated energy's part for the mechanism drive and the emission exhaust is connected. These series of actions are called the operating cycle of the petrol and diesel engines. The operating cycle is ensured by petrol and diesel combustion engines, which operate using different construction principles. Commonly known types of petrol and diesel engines with a static function of the emission exhaust, are engines with rectilinear piston motion. Out of these engines, for example the four-stroke petrol engine operates in four phases, i.e.: in the first phase, the fuel mixture intake takes place, which is the mixture of air and petrol, the second phase is the compression, in the third phase, the compressed fuel mixture explodes due to an electric spark, and in the fourth phase, the exhaust emissions are released. The four-stroke petrol engine with direct injection, also operates in four phases, i.e.: in the first phase, the air intake takes place, in the second phase, the air compression and consequently fuel injection takes place, in the third phase, compressed fuel mixture explodes due to an electric spark, and in the fourth phase, exhaust emissions are released. In case of a diesel engine, in the phase of compression, the air is compressed until it reaches the explosive temperature, and at the end of the compression process, the air is enriched by diesel by injecting it into the cylinder's combustion chamber, which leads to spontaneous ignition of the fuel mixture and to the explosion.
The energy transformation pressure on the piston provides the transmission of the piston's rectilinear motion through the connecting rod and in connection with the crankshaft transforms the circular motion into the rotary motion. Generally, operation of the cylinder engine requires also other moving parts e.g.: camshaft, valves and the distribution to the camshaft.
The gyratory piston engine (Wankel's engine) represents a more progressive concept in providing and realizing the piston combustion engine's actions. Its effectiveness compared to the diesel and petrol engines is increased by using only a minimum of rotary parts and by absence of the parts making a shifting reversible movement. The principle of its operation is as follows: the preparation process strokes, the fuel ignition and the exploitation of the created energy during the fuel explosion take place operating with a gyratory piston, in a shape of a triangular spherical prism. The gyratory triangular piston and the eccentric shaft rotate around their own axles, however, at the same time, the piston moves on the orbit determined by the orbit of the centre of the eccentric shaft, thus the shaft moves in an eccentric manner. The inside of the cylindrical box is shaped as an epitrochoid. The side walls of the piston are constantly pressed to the walls of the box. The sealing of the gyratory piston is secured by metal sealing ledges and the piston is equipped by rounded ledges. Type of the engine, shape of the combustion chamber and upper lubrication is manifested mostly by increased fuel and lubrication oil consumption of the Wankel's engine.
Several solutions deal with the effort to improve the Wankel engine's gyratory piston parameters, which could be included in the present state of relevant technology, however, none of them represents major concept changes.
The rotary nasal annular engine with internal combustion solves the above mentioned problems mainly by means of containing only two (favourably three or more) rotary units placed in a block, but also thanks to the method of preparation of the fuel mixture, its transfer, expansion, usage of released energy in the combustion area, transfer of exhaust emission and its exhaust out of the engine. The rotary nasal annular engine with internal combustion is equivalent to the piston four-cylinder four-stroke engine, whose mechanism, for example in case of two cylinders, consists of as many as 35 movable basic parts of the engine (crankshaft, flywheel, 4 con rods, 4 wrist-pins, 4 pistons and 4 sets of piston rings, camshaft, 4 lifters, 8 valve springs+spring gripping elements, 4 intake valves, 4 exhaust valves, not considering the camshaft's driving mechanism (gear wheel, gear belt, pulleys), compared to two or more moving basic parts of the rotary annular nasal engine with internal combustion. The rotary nasal annular engine with internal combustion does not contain a crankshaft, camshaft, valves, pistons, rods, lifters, rockers, valves and distribution to them, moreover, it does not contain eccentrically rotating elements (crankshaft, rotor of the Wankel's engine). The merit of the rotary nasal annular engine with internal combustion lies in consisting only two moving basic parts—rotors, in comparison to 35 movable basic parts of an adequate four-cylinder piston engine. Rotors of the rotary nasal annular engine with internal combustion are placed in a block and actions such as preparation of the fuel, initiation of the fuel combustion, transformation and utilization of energy and emission exhaust take place in a sequence of construction and other coherent parametrical and functional combinations of processes typical for operation of a combustion engine.
These processes are initiated and take place by exploitation of at least one pair of the first and second rotor (favourably two or more second rotors) and a block, in which the rotors are placed and rotate synchronously while maintaining partial constructional and functional contact, which is continuous, sealing and non-sealing. Turning axes of the rotors are skew, which are either mutually perpendicular or not perpendicular. The rotors continuously complement each other from the constructional and functional point of view. The block, apart from bordering the space, in which the rotors are placed, continuously determinates sealed or loose parts of the engine's combustion chamber, which is in the appropriate shape of a torus. The first rotor is of a cylinder—plate shape with at least one nose on its outer circumference wall, and it moves inside the combustion chamber, which is surrounded by an inner wall of the block and circumference surface of the first rotor as well as the rotating second rotor (favourably more second rotors). The second rotor (favorably more second rotors) can be annularly shaped with at least two constructional modifications with slots on its inner circumference. The first rotor contains a rotating output—shaft, identical with the axe, for transition of the energy of the powered system. The second rotor (favourably two and more second rotors), also contains as a rotating output for example on the circumference a gearing, and it is synchronously connected with the first rotor and powered by the first rotor. During rotation, both rotors maintain appropriate sealing and non-sealing contact, the contact is maintained also between the rotors and the block. Particular contact parts as well as constructional modifications of both rotors and the block create conditions in the chamber, which are typical for combustion engines.
In the following description of these actions, the principles of the actions of the rotary nasal annular engine with internal combustion are identical to the actions of the rotary nasal engine with internal combustion, registered in the SR Industry Patent Office, under the registration No. PP 5068-2006, from 8 Aug. 2006.
By an appropriate position of the second rotor (favourably more second rotors) and the block as well as through the openings in them, and by rotation of the first rotor, the medium intake into the combustion chamber is secured (air, oxygen, or fuel mixture). The intake medium is transferred by rotation of the first rotor in front of the nose, and it is compressed at the contact area of the second rotor (favourably two and more second rotors), and it is transferred through the transfer system in the second rotor (favourable two or more second rotors) into the combustion chamber behind the nose of the first rotor. The injection of the fuel into the compressed air or oxygen takes place in the combustion chamber (fuel mixture can be conveniently compressed by the rotation of the second rotor—favourably two and more second rotors), which initiates the ignition of the fuel mixture. Explosion initiates expansion and rotation of the first rotor. Consequently, through the rotation of the first rotor and through the determination of the second rotor (favourably two and more second rotors) and the block and through the slots as well as through further determination of the second rotor (favourably two and more second rotors) and by the rotation of the first rotor, the emission exhaust is realized. Consequently, the nose of the first rotor moves through the contact area using the slot on the second rotor and the intake phase begins repeatedly.
In the case of the rotary annular nasal engine with internal combustion, which is the subject of the protection, significant differences and mostly advantages are obvious compared to the piston engine, i.e.: significant simplification and reduction in size of the construction of combustion engines, decrease of production expenses, high reliability and no-failure operation, which consequently leads to decrease of repair and maintenance costs, moreover, improvement of fuel efficiency, increase of actual performance of the engine, significantly lower mechanical losses, higher total efficiency compared to pistons engines, mainly due to better mechanical efficiency, there is no oscillation during rotation of a rotary engine as there is during shifting movement in the case of a piston engine, thus vibrations are not transferred into the frame of e.g. a vehicle, this consequently reflects in a lower noise, lower stress of the springs, maximum combustion pressure in the combustion chamber of the rotary engine is supposedly lower by more than 30% compared to an equivalent piston engine, lower short-term mechanical levy of the rotor nose and the chamber, the maximum temperature in the chamber during combustion is supposedly lower, moreover, the CO and the unburned hydrocarbon (HC) production is lower compared to a piston engine, there is no torso oscillation, only the output shaft is stressed during torsion, perfect balance of the engine, the motor is capable of operating at a considerably higher RPM (higher RPM=better performance), when applied in e.g. sport cars, supposedly, the engine—due to perfect balance—can run at cca. 20 000 RPM, the rotary engine can be constructed as either petrol or diesel engine, it is also appropriate to use other conventional as well as alternative fuels, the engine can operate with natural intake or it can be turbo-supercharged, the rotors also function as flywheels. During the engine's expansion, the torque takes place directly on the shaft, in contrary to the piston engine with a crank mechanism, where the resulting force/energy onto the piston is transferred from the piston through the bearings of the piston shank, shaft and the shaft bearing to the crankshaft, and during this transfer, mechanical losses occur together with loading of several components. The rotary nasal annular engine with internal combustion operates with a significantly effective usage of the space, moreover, it is approximately one third of the height, also one third of the length of an equivalent four-cylinder piston engine with the same actual power, thus, supposing the rotary nasal engine with internal combustion had the same proportions as the piston engine, its actual power would be several times higher. Another advantage of the rotary nasal annular engine with internal combustion is the assumption that it will reach approximately up to 70% of the value of the power weight of the piston engine; maximum piston speed compared to the piston engine will be lower by approximately 8%. Mounting of a rotary nasal annular engine could by realised in 35% shorter time as mounting of an equivalent four-cylinder piston engine.
Advantages of the rotary nasal annular engine with internal combustion compared to the Wankel engine are: there are complications with corners sealing in the case of Wankel engines, however, these do not occur in the case of the rotary nasal annular engine with internal combustion. The surface-cubature ratio of the combustion chamber is considerably smaller than in the case of the Wankel engines which have a long, slotted combustion space, moreover, CO emissions and not-burned hydrocarbon (HC) that emerge at the combustion space walls of the rotary nasal annular engine will be lower than in the case of the Wankel engines, and comparable to the values of pistons engines. It is possible to apply upper lubrication; however, lower lubricant consumption is assumed compared to Wankel engines.
The rotary nasal annular engine with internal combustion is even more effective in terms of space filling, compared to the rotary nasal engine with internal combustion, the rotary nasal annular engine with internal combustion comprises twice as high engine power as the rotary nasal engine, and in terms of the processes taking place inside, the engine is equivalent to a four-cylinder four-stroke piston engine.
Working pair (favourably three and more) of the rotors of the rotary nasal annular engine with internal combustion, together with the block, as one complex possibly on the same axle—placing the shafts simultaneously with other favourably similar units, which is an advantage compared to the rotary nasal engine with internal combustion, where the axles of both rotors are non-intersecting.
The principle of the rotary annular nasal engine with internal combustion and the process of the combustion mixture preparation, its ignition and the exploitation of the released energy for the exploitation of the described process, is schematically illustrated in the pictures. Considering that the solution, which is protected, creates premises for a number of constructional application variations and its merit can be described through projecting different states, individual pictures ought to be perceived only as illustrative, in order to illustrate the invention's merit.
The
The rotary nasal annular engine with internal combustion is unique and exceptional thanks to its original construction—it has only two (favourably more) rotary parts—rotor 1 and 2 (favourably other second rotors 9) placed in the block 3 and thanks to the processes typical for the operation of a combustion engine.
The rotary nasal annular engine with internal combustion operates with the same principles as the rotary nasal engine with internal combustion, registered in the SR Industry Patent Office, under the registration No. PP 5068-2006, from 8 Aug. 2006.
The rotary nasal annular engine with internal combustion operates using at least one pair of the first rotor 1 and the second rotor 2 (favourably other second rotor(s) 9) together with the block 3, which actually contains rotating rotor 1 and rotor 2 (favourably other rotor(s) 9). Rotor 1 and rotor 2 (favourably other rotor(s) 9) synchronously rotate and continuously maintain partial constructional and functional contact, which is between the rotors 1 and 2 (favourably other rotor(s) 9) and the block 3 sealing and non-sealing.
The axes of the rotor 1 and rotor 2 (favourably other rotor(s) 9) are either mutually parallel or appropriately diverted from the parallel direction. The second rotor 2 (favourably other rotor(s) 9), favourably annularly shaped, passes through the combustion chamber 4.1, (4.2) dividing it at at least two places, compared to the rotary nasal engine with internal combustion, where the second rotor 2 passes through the combustion chamber 4.1, (4.2) dividing it at one place. The second rotor 2 (favourably other rotor(s) 9) contains a gear 2.10, as a rotary output, for example on its circumference, and it is synchronously connected through it by the gear mechanism 8, with the first rotor—which is the driving rotor 1.
The first rotor 1 and the second rotor 2 (favourably other rotor(s) 9) continuously complement each other from the constructional and functional point of view. Block 3, apart from functioning as cover of the space, in which the first rotor 1 and the second rotor 2 (favourably other rotor(s) 9) are placed, it continuously determinates together with the rotor 1 and the second rotor 2 (favourably other rotor(s) 9) sealed or loose parts of the engine's combustion chamber 4.1, (4.2) together with the rotors. The engine's combustion chamber 4.1, (4.2) is appropriately shaped in the shape of a torus and is bordered with an inner wall 3.1 of the block 3 and with the circumferential surface 1.9 of the first rotor 1, as well as the rotating second rotor 2 (favourably other rotor(s) 9). It is advantageous, if the first rotor 1 is in a cylinder—plate like shape with at least one nose 1.2, 1.3, on its circumference 1.9, which rotates in the engine's combustion chamber 4.1, (4.2). The second rotor 2 (favourably other rotor(s) 9) is favourably of an annular shape, with slots 2.7, 2.8 (favourably with slots 9.7, 9.8 of other rotor(s) 9) on its inner circumference 2.11 of the second rotor 2 (favourably on the inner circumference 9.11 of the other rotor(s) 9). The first rotor 1 contains a rotating output-shaft 1.1 on the rotating axle in order to transmit the power into the driven system. The second rotor 2 has on its outer circumference a gear 2.10 (favourably gear 9.10 on the other rotor(s) 9), and it is synchronously connected through it by the gear mechanism 8, with the rotary output-shaft 1.1 of the first rotor 1. The contact part of the first rotor 1 and the second rotor 2 (favourably other rotor(s) 9) has at least two slots 2.7, 2.8 (favourably with slots 9.7, 9.8) on its inner circumference 2.11 (favourably on its circumference 9.11 on the rotor 9), and at least one nose 1.2, (1.3), whose circumference 1.8 duplicates the volume of the combustion chamber 4.1, (4.2), and this nose 1.2, (1.3), is placed on the circumference 1.9 of the first rotor 1. Slots 2.7, 2.8 (favourably slots 9.7, 9.8) are on ther inner circumference 2.11 (favourably on its circumference 9. 11 on the other rotor(s) 9) are equipped with specific constructional modifications, which enable sealing and non-sealing transfer of the nose 1.2, 1.3, through the slots 2.7, 2.8, of the second rotor (favourably through slots 9.7, 9.8 of the rotor 9). Mutually appropriate position of the second rotor 2 with the opening 2.2 in it (favourably through opening 9.2 on the other rotor(s) 9), towards the block 3 with the opening 3.2 in it, along with determination of the second rotor 2 (favourably other rotor(s) 9), and with the rotation of the first rotor 1, secures the absorption of the medium 7 (air, oxygen or fuel mixture) into the engine's combustion chamber 4.1, behind the nose 1.3. Intake medium, due to rotation of the first rotor 1 and due to determination by the second rotor 2 (favourably other rotor 9), is compressed inside the engine's combustion chamber 4.1 in front of the nose 1.2. Compressed medium is moved from the front of the nose 1.2 of the first rotor 1 of the engine's combustion chamber 4.1 through the transition system 2.4, 2.5, 2.6 (favourably other transition system 9.4,9.5,9.6 of the rotor(s) 9), it's intake opening 2.4 and outgoing opening 2.6 (favourably other outgoing opening 9.6 of the rotor(s) 9), which are situated in the second rotor 2 (favourably other rotor(s) 9), into the engine's combustion chamber 4.2, behind the nose 1.2 of the first rotor 1, after the transfer of the nose 1.2 of the first rotor 1 across the contact area of the first slot 2.7 of the second rotor 2 (favourably the opening 9.7 on the other rotor(s) 9). Here, the medium 7 (air or oxygen, possibly fuel mixture) can be pressed by the rotation of the second rotor 2 (favourably other rotor(s) 9) and by its appropriate shape (during the transfer of the air or oxygen, consequent injection of the fuel takes place 5.1), and the explosion of the fuel mixture 7 in the engine's combustion chamber 4.2 is initiated, either by compressing the mixture which would lead to spontaneous ignition or by a spark 5.2. Rotation of the first rotor 1 is initiated by explosion and expansion, and by generated pressure on the nose 1.2 of the rotor 1. Consequently, by rotation of the first rotor 1 and by mutually appropriate position of the second rotor 2 (favourably other rotor(s) 9), with the opening 2.3 in it, (favourably through the opening 9.3 of the other rotor 9), towards the block 3 with the opening 3.3 in it, along with determination of the second rotor 2, the emissions exhaust 6 from the engine's combustion chamber 4.2 takes place. Consequently, the nose 1.3 of the first rotor 1 is transferred through the contact area of the second slot 2.8 (favourably other slot 9.8) of the second rotor 2 (favourably other rotor(s) 9) and the intake of the medium takes place repeatedly.
The rotary nasal annular engine with internal combustion can be applied in all applications which nowadays use classical piston combustion engines, including static and dynamic engines, small, middle sized car engines, aircraft and big engines, as well as high-speed or low-speed engines. The rotary nasal annular engine with internal combustion can be constructed in the same manner as a petrol engine; it is also possible for the engine to operate using other conventional and alternative fuels, it can operate with natural absorption or turbo-supercharging. During transformation of the chemical energy into mechanical energy, the rotary nasal engine operates in a rotary motion not in a rectilinear motion, thus there is no swinging motion, and therefore there is no reversible phase and eccentric rotation. The number of movable parts is extremely low—2 or 3, which assumes a low break-down rate and therefore high reliability. The operating pair (favourably three or more) of rotors together with the block can be synchronously combined in various combinations, as it is described in the Description of the invention and the Patent rights—protection entitlement.
