Definitions

  • the invention relates to the field of engine building, it is possible to apply it wherever internal combustion engines are used.
  • piston ICEs of the two-stroke and four-stroke cycles have been known since the 60s and 70s of the XIX century (S. Baldin, “Internal Combustion Engines”, Moscow, Imka-press, 1923).
  • the movable cylindrical piston performs linear reciprocating movements inside the stationary cylinder.
  • the piston is connected by a connecting rod with a crankshaft.
  • a pre-compressed mixture of fuel and air vapors is burned in a hermetically enclosed space between the piston and the cylinder due to an increase in the pressure of hot gases, a linear working movement of the piston is carried out simultaneously with the combustion process, which is converted by the crank mechanism into rotational motion of the crankshaft and reciprocating motion of the piston itself .
  • the working cycle for example, of 4-stroke engines consists of successive technological steps - cycles: suction (intake) of the working mixture, compression of the working mixture, ignition of the working mixture with expansion of the working fluid
  • a rotor is located in a round or oval chamber of the housing, the axis of rotation of which is offset relative to the center of the cylindrical surface of the housing.
  • Movable blades are placed in the rotor body, which can be extended in radial directions and abut against the walls of the housing. The difference in the extension height of the adjacent blades leads to a difference in their area, therefore, when the space between the adjacent pressure blades is applied inside, a driving force arises towards the blade with a larger area, which rotates the rotor.
  • a high-quality internal combustion engine has not yet been created on the basis of this principle, although pneumatic motors that implement this principle have been operating successfully for a long time.
  • motor resources have a complex structure due to the presence of a crank mechanism with a large number of alternating inertial loads and reciprocating movements, a complex gas distribution mechanism with its drive, low specific power and restrictions on increasing the number of revolutions and torque forces.
  • Wankel and Frede rotary engines have high specific
  • thermodynamic efficiency of modern internal combustion engines does not exceed 30%.
  • a rotary engine - the closest analogue of the claimed invention contains in the housing two process units in the form of rotor sections, each in its own cavity. A rotor with two blades rotates to each cavity and there are two locking drums.
  • the first technological unit (rotor section) is the compression section of the working mixture (compressor), and the second technological unit (rotor section) is the combustion section - expansion (power machine or power rotor section).
  • Each technological unit works by changing the volumes of compression or expansion resulting from the rotation of the rotors and locking drums. Due to this rotation of the rotors between the rotor blades and the surfaces of the locking drums, segments of variable volume are formed.
  • coinciding essential features between the claimed invention and the closest analogue under consideration is the separation of the engine design into different technological cavities - chambers (rotor sections), where the processes of inlet-compression and expansion-expansion of the working fluid separately occur.
  • the coinciding features are the main working elements of the engines - rotating rotors made in the form of disk-shaped elements with piston blades, one of which compresses the fresh charge of the working mixture in its section, and the other converts the pressure of the working combustion gases (working fluid) into mechanical rotational motion , as well as working in tandem with each rotor of the locking drums with cavities to pass the rotating blade.
  • a large (largely insurmountable) difficulty for real gas exchange processes is the large length of the bypass channel of the compressed working mixture from the compression segment of the compressor rotor section to the expansion segment of the power rotor section.
  • a short bypass channel cannot be made.
  • the volume of such a channel is up to 2/3 of the volume of the compression segment, that is, the main process of expansion of the compressed
  • the working mixture will occur not in the expansion segment of the power rotor section, but in the channel - bypass gas duct. Consequently, in the expansion segment of the power rotor section, the Working Mixture will turn out to be under low pressure and all the more badly ignite and burn on the speed expansion line.
  • the elements that produce the process of locking and unlocking the volumes of the compression segments of the compressor rotor section and the expansion segments of the power rotor section are grooves - “streams” on the end surfaces of the rotors of both rotor sections. This decision is extremely unsuccessful, because with a short length of these grooves, “streams”, they will not be able to provide gas exchange processes along the entire length of the stroke of the rotor blades in segments of the power rotor section, which will drastically impair the thermodynamic efficiency of the engine.
  • the rotors are arranged with three blades, and the locking drums in the rotor sections are arranged in two, and each locking drum has two through recesses where the rotor blades will pass. It follows that the lateral cylindrical surfaces of the rotors and locking drums must move with different linear speeds and friction - sliding will occur on the line of their contact, which will require active lubrication of these surfaces;
  • the rotors are arranged with three blades, and the locking drums in the rotor sections are arranged in two, and each locking drum has two through recesses where the rotor blades will pass.
  • dead zones will form when the high pressure combustion gases are trapped between two adjacent rotor blades (in the power rotor section) and will not produce useful expansion work.
  • the compressor rotor section there in the working processes there will be a period for each revolution when the working mixture will be sandwiched between adjacent rotor blades and compression will not work on it.
  • the presence of such zones for each rotation of the shaft in both rotor sections will significantly reduce the efficiency considered by the closest analogue of the engine
  • the objective of the invention which is implemented in this design, is to create a compact highly efficient internal combustion engine, with an efficiency of more than 50%, in which the following samples of high technical achievements are connected, each of which is independently a significant technical task:
  • HEXISTAN ROTARY ENGINE contains a fixed hollow cylindrical body, consisting of three technological units. That is, the case is divided by partitions into three
  • each of the three rotor sections a cylindrical rotor with rotor blades is located, and all engine rotors are rigidly mounted on one shaft. Also, in each rotor section there are locking drums, according to the number of working rotor blades. Also on the body is arranged a gear drive in the movement of the locking drums.
  • a feature of the invention is the mutual arrangement of the rotor sections of the engine: two power rotor sections (expansion-release sections), with their working rotors in which combustion chambers are arranged, and a compressor rotor section (inlet-compression section) with its rotor, with this
  • compressor rotor section is located between the power rotor
  • the proposed engine when each of the rotors is equipped with two blades, and two combustion chambers are arranged in the rotors of the power rotor sections, the proposed engine performs 4 working cycles per 1 revolution of the main shaft, while a 4-cylinder single-cylinder piston motor only 0.25 working cycle per a full revolution of its crankshaft, and a single-cylinder Wankel engine - 0.75 cycles of useful work per revolution of the eccentric shaft.
  • high-performance vapor phases can be built into the ICE duty cycle, which will translate the high temperature of the combustion gases and the temperature of the engine parts into high-pressure steam.
  • the engine does not need to have high speeds of the main shaft, although there are no restrictions to increase its speed in the design and you can expect prototypes to reach speeds of up to 20 for gas turbines such as aircraft engines thousand revolutions per minute, but - unlike gas turbines - at high torque parameters even at low revs and at low fuel consumption.
  • the method of converting the pressure of the working gases into the movement of the working shaft is a simple rotational movement, which eliminates losses characteristic of a piston engine with its crank mechanism.
  • the torque of the proposed design is noticeably greater than that of the piston
  • the length of the stroke of each blade compared to a traditional piston motor, which has a piston diameter close to the surface of the piston blade (the stroke length of the piston engine is approximately equal to the diameter of the piston) will be 6 times larger.
  • the temperature and pressure of the gases discharged from the expansion chamber (segment) to the exhaust should be minimally excessive.
  • the engine is well balanced - all moving engine parts
  • the engine is compact, has a simple design and a small number of parts, which makes it possible to achieve higher operating parameters, compared with the existing motors of different types.
  • each rotor of the rotor sections is equipped with two working blades, two locking drums are arranged in each rotor section, and two combustion chambers are made in the rotors of the power rotor sections.
  • a six-stroke rotary engine (figure 1) contains an outer casing, which consists of three separate rotor sections: two power sections (sections “expansion-release”) - (elements 1-1 and 1-2) and one compressor section (section "inlet - compression ”) - (element 2).
  • the rotor sections are separated by partitions (element 3), and on the sides are limited by end caps (element A).
  • Each rotor section contains a working rotor (element 5) and locking drums (element 6).
  • the rotors of all rotor sections are located on one main motor shaft (not shown in the drawing), while the rotors of the working rotor sections contain a combustion chamber (element 7).
  • the gearbox of the drive is set in motion for all the locking drums (not shown in the drawing) and the locking drums are located on two common shafts of 3 pieces.
  • the engine mixture supply windows (element 8), exhaust windows (element 9) were made in the engine case, for exhaust gas discharge, and the bypass sections of the compressed working mixture (element 10) were made for the partitions between the rotor sections, as well as channels — grooves for exhausting combustion chambers of a high pressure working fluid (element 1 1).
  • the end caps there are nests for spark plugs (element 12) and windows for water injection (element 13).
  • the rotors are a cylindrical part, rigidly
  • the locking drums are cylindrical parts, on the side surface of which are made recesses - cavities for transmission during rotation of the working rotor blades.
  • the cylindrical surface of the rotor and the locking drums by selecting the diameters and frequency of rotation without friction, run around each other, and the diameters of the drums are made multiple times less than the diameter of the rotor.
  • the geometry of the internal working space of the engine, where the main technological processes take place sequentially and cyclically, is an annular cavity. It is arranged so that the locking drums that come into contact with the outer cylindrical surface of the rotor with their lateral cylindrical surfaces divide this circular, annular cavity (figure 2) into equal working sectors (element 14), in which the rotor blades can move in an arched volume of each . In turn, with this movement in the arcuate sectors, the rotor blades divide each of these working sectors into two segments of variable volume on the camera (figure 3): the expansion segment (element 15) and the compression segment (element 16). In the power rotor sections (expansion-output sections), the working sectors will be divided into expansion segments and output segments, and in the compressor rotor section (inlet-compression sections), the working sectors will be divided into intake segments and compression segments.
  • the sequence of rotational operating cycles of the engine is as follows - for example, the motor ⁇ figure 1), which has three rotary sections: one
  • compressor section (element 2) (inlet-compression section), and two power sections (expansion-exhaust sections): power section A (element 1-1) and power section B (element 1-2).
  • Each rotor section has a two-bladed rotor (element 5) and two locking drums (element 6) in each rotor section, the rotors of the power rotor sections have two combustion chambers
  • the working mixture begins to burn in a locked volume.
  • the rotors of all sections continue to rotate for about 30 degrees of angular distance - this time all the combustion chambers remain tightly closed, and in two of them, where the Working Mixture is lit, pressure continues to increase and more and more a working fluid is created.
  • the blades of all rotors pass through the openings of all locking drums, and the annular working space of all sectors of the rotor sections is not hermetically divided into separate chambers - technological segments.
  • the rotation of the rotor and the locking drums in the compressor rotor section leads to the division of the working arcuate sectors of this section into segments of the “inlet” and “compression”.
  • the “intake” strokes of the fresh mixture of the Working Mixture start behind the rotor blade (in the direction of rotation of the rotor), and the front of the blade starts the “compression” of the mixture of the Working Mixture that was introduced into this sector in the same “intake” cycle.
  • the combustion chambers are connected through the channels of the bypass of the working fluid with expansion segments and through these expansion segments themselves - further - with the release windows from them into the atmosphere. In this case, the pressure in the combustion chambers becomes equal
  • combustion chambers move with the rotation of the rotors to the position when they lose contact with the expansion segments of the power rotor sections, and are locked.
  • Next - moving combustion chambers work as follows:
  • the chambers move further, disconnect from the intake windows, after which the odd combustion chamber of the rotor section A and the even combustion chamber of the rotor section B are connected to the nests of the spark plugs and they ignite the charge of the Working Mixture in these chambers.
  • the period in the combustion chambers occurs when all the combustion chambers remain locked.
  • the combustion process takes place in a closed volume of the charge of the Working Mixture, and two other combustion chambers carry out “idle run”, approaching the windows of the future bypass of the compressed Working Mixture.
  • the “working” combustion chambers due to the rotation of the rotors, move to the places where they are connected to the channels - grooves of the bypass of the high-pressure working fluid in
  • the engine as a diesel engine - with fuel injection directly into the volume of the combustion chamber, which is already filled with highly compressed and heated air from this.
  • the main feature of the invention is the relative position of the rotor sections for various purposes and the coordinated rotational movements of the working rotor blades of the power rotor sections in their cavities, rotor blades
  • compressor sections in its cavity complex surfaces of the locking drums (each located in its own nest), combustion chamber cavities in the rotors of the power rotor sections, as well as the location of the inlet, bypass and exhaust windows, which in the joint work package creates the possibility of coordinated implementation of many technological processes simultaneously processes

Abstract

La conception de ce moteur et son procédé de fonctionnement se fondent sur deux solutions techniques novatrices : - dans le domaine de la réalisation optimale des temps (processus technologiques) d'un moteur ; - dans le domaine de la réalisation d'un schéma parfait de conversion de la pression des gaz de travail en une rotation de l'arbre principal du moteur ; - dans le domaine de la réalisation optimale des temps (processus technologiques) d'un moteur on obtient l'isolement du temps "combustion - dilatation" (qui, dans les moteurs à combustion interne traditionnels, est combiné) qui englobe deux processus technologiques à la fois, en un temps isolé du processus technologique "combustion - formation d'un fluide de travail à haute pression". Ce 5-ème temps supplémentaire est effectué dans une chambre de combustion séparée à volume inchangé. On a introduit un nouveau 6-ème temps technologique qui comprend l'injection d'eau dans le segment de dilatation visant à transformer l'eau en vapeur pour augmenter la quantité et la pression du corps du fluide de travail ; dans le domaine de la réalisation d'un schéma parfait de conversion de la pression des gaz de travail en une rotation de l'arbre principal du moteur, cette conception utilise au maximum le principe du levier en se fondant sur la géométrie et la dynamique du rotor cylindrique avec pales de travail se trouvant constamment en rotation sous l'effet de la pression des gaz de travail.
