FOUR-STROKE AXIAL PISTON ENGINE STAIN (UGA1U - 1yotor)

Using the model oTHoeHYeii for engine building, in ttacTHocm, for four-stroke piston internal combustion engines (ICE) and can be used in various power plants, due to the small cross-sectional size and relatively small weight of the axial piston, the ICE is preferable to use in small aircraft designs, boats.

The four-stroke piston ICE 13 with a single-row for two-row (U-yubraashi) arrangement of blocks of chkhlidrov is known, containing a certain amount (custom) in the caddy block 4) chschlshtsrov porony and krkvoshigoyu-oatzgnnyh mechanisms, transferring the rotational speed, energy consumers are connected.

The disadvantages of such engines are: firstly, they have a defined strength of 1 (onst hand, which is in the presence of a complex mechanism for driving gas valves and a complex configuration of the crankshaft; secondly, the impossibility of fully balancing the engine from inertia forces; thirdly, large overall and More about engine performance.

Known for the design of four-stroke axial-piston ICE 2.3, comprising a housing, a cylinder block, a combustion chamber; the pistons, located in the cylinders, the fuel supply system, while a flat rotating washer is rigidly fixed to the engine b & h, which is connected to the pistons using spherical Ш1р1иров.

Known for the design of a four-stroke axial-shaft engine ICE 4, a casing body, combustion chambers, a unit for construction works; vices located in 1 cylinders, a fuel system, an inlet and a vent valve, two auxiliary profile washers that control the movement of the valves, a mechanism for translating the translational movement of the pistons into rotational motion of the engine shaft, including the main (power) 1 fixed profile civic and evaluid (| a few polarities, which, when running through the washers, transfer the force of the shrogdy to the washer, rotating it and with it the motor shaft to which the energy consumers are connected.

This design axial-poronovoy DU S3,43 selected as a prototype.

The disadvantages of the axial-neural ICE 3.41 is that with one main profile washer, the initial forces act on the pressure of the gases and the forces of the best force on the bearings of the motor shaft. Additional thrust bearings are required to be swabbed. This essentially complicates the design of the engine, and the presence of additional friction forces leads to additional loss of mechanical energy and, as a consequence, to a decrease in the KPD of the engine.

- 3 In addition, with only one main role, Evaibe assigns a difficulty in balancing the engine, that is, in QOJQIOII balancing the moment of inertia of the inertia forces and the roars In the case of an even number of powders and cylinders in the prototype 141 there will be a large unevenness of 1 torque and the angular speed of rotation of the motor shaft. All this 9to leads to greater stress on the engine mounts, reduces reliability and reduces engine longevity.

In the well-known prototype, for converting the translational motion of the pistons into rotational motion of the engine shaft, cylindrical rollers and a special main profile sinusoidal washer are used, the working surface of which is ruled, while forming a straight line, the perpendicular axis of the motor shaft is always perpendicular to the width of the working surface. The planned contact of the roller ai washers must occur in a straight line - indicated by the generatrix. However, in the engine, the roller can skew relative to the washer, and even with a slight skew, the contact is transferred to one of the boundary points and becomes point. In all cases, large contact forces and large frictional forces arise, leading to increased wear on the working surfaces of the roller and washer. Therefore, this design is short-lived.

The objective of the utility model is to increase the efficiency and economy of the engine by increasing the overall power of the engine, reducing fuel consumption, increasing efficiency engine, reducing friction and wear of the working surfaces of engine parts, reducing mechanical energy losses and increasing engine durability, as well as reducing the complexity of the design and engine stoich.

- 4 The stated problem is solved by the fact that in the four-door open door there is a Porshnev DOS, containing a body, Stuyup cameras and tslmschdry raspoloyoyee around the circumference inside the housing; powders; circulated in cylinders, fuel-air mixture supply system, inlet and outlet valves, valve drive mechanisms, rotary central engine shaft, to which the power consumers are connected, unlike the OV prototype, the engine contains a symmetrical, reliably central 1 transverse plane, two camera units combustion of 16 cylinders with pistons marked in them and a two-stage mechanism for converting translational dvukhekii orshy into rotational motion of the engine shaft, while p the crankshafts for each poronya are transforming the translational motion of the porony into rotational two-way cranks, and on the second tap the resulting cranks are transmitted to the motor shaft; it is possible to change the magnitude of the angular velocity, that is, in the design itself there is a single-stage gearbox,

1 completed in the claimed design (kg F) of symmetrical ratio; 1 on the central central transverse plane of the engine of two blocks of combustion chambers and Ts11li1zdrov, with pistons and pistons ensures equality of gas forces acting on the crankshaft of the engine and on the central double-sided gear wheel, and hence the gas forces they are closed inside and are not proud of the motor shaft bearings, which will be loaded only with torque and the forces of the weight of the rotating parts.

in the claimed konsurukhtsmk, all the aerials, aatuns and gray shakes are pairwise and snappy, they move and rotate in the same direction but in opposite directions. Their total number is equal to, where 2,3,4 ,, .. etc. This will ensure complete equilibrium of the engine from indrcial forces and their cements. The engine does not require any additional devices or technological operations for balancing. Only requisiteness is needed in the dimensions and masses of parts. In the claimed design, cranks in adjacent cylinders can be installed relative to each other on some design angles so that in any two cylinders (combustion chambers) the same operation phases (beats) of the engine in any moment of time. This will lead to a better uniformity of rotation of the motor shaft relative to the prototype, which means lower loads on the engine mounts. The central double-sided gear wheel (which has a significant moment of inertia and performs, in addition to the main role, the role of a flywheel smoothing the uneven rotation of the motor shaft will also contribute to this).

An important advantage of this engine is that in its design, in comparison with the prototype, there are absolutely no new mechanics, such as a sphophilic washer with rollers. The design of the south-facing engine consists of well-developed units: crank gears and gear conical collars. These units can be made with low contact forces at the joints, with good lubrication and low losses of mechanical energy per run. So k, p, d, the engine will be higher than that of the prototype, and the specific fuel consumption is less.

The mating in the claimed design of the crank mechanisms, bevel gears, as well as the circular arrangement of qi

- 6 cylinders around the gearbox shaft, allows you to have a homogeneous engine with a small cross-section and relatively LOW weight. An important advantage of this engine is that its design of FDI uses only components well-known in the art: parts v 1 crankshaft 1 gear 1 e 1 gear westernm Well secret technology of their production and the general simplicity of design1. Will contribute to: even the cost of the engine.

The essence of the utility model is illustrated in the drawing. On Fig. G shows a longitudinal section of the inventive four-stroke axial powder two. We declare: the engine consists of two blocks with 1 metric, with respect to the central transverse plane of the engine, identical blocks. Specifically, the engine contains a cylindrical housing I (fopffii, in the bokomls parts of which the cylinders 2 of the engine with combustion chambers 3 are located at each circumference. In the clinchers are tailors 4 with fingers, which are connected with the help of jatuns 5 to krivott1pa & I b, to which, in turn rigidly attached conical holes 7, which are meshed with the central gear double-sided bevel gear 8, mounted on the shaft 9 of the engine, placed in the bearings of the housing. In the cylinder heads of the engine there are inlet and outlet valves 10 with their springs, which opposite ends are supported by GT valve profile washers, mounted on the motor shaft.

The operation of the four-stroke axial piston internal combustion engine is carried out as follows. In the position of the pistons, connecting rods and cranks shown in Fig. T., that is, in the first cycle of the engine, the cylinders are filled with fresh mixture, which is worked out by the engine corrector. In this case, both pistons move to the lowermost volume of the chamber 7 soapacTfter guaranteed to the maximum, the intake valve is open at this time, and the exhaust sfirpuT.

The opening of the valves of both units is controlled by the flap profile washers II, special protrusions are secured on the inner surfaces of the shells, the valves are moved away when the shaft rotates, and the springs move the valves in the opposite direction, closing the combustion chamber. When the pistons reach the lowest position, the intake valve closes and the exhaust valve is still closed. Both combustion chambers are filled with fresh mixtures), and when the valves are closed, the second cycle of the engine operation is squeezed - compression of the working mixture - the pistons move to the highest position, i.e. removed from the central transverse plane. When the volume of the combustion chamber becomes minimal, the BoaropaHve is tedious, for example, from an electric candle, after which the third cycle of the engine starts - burning fuel, expanding the working fuel and doing useful work. The pins of the rods, connecting rods and cranks are again in the position shown in fig. .I. It is in this cycle that a torque is generated that is transmitted through the conical toaster to the central two-sided gear wheel 6 fixed to the motor shaft 9 and leading it to rotation.

Then, with the help of valve profile washers II, the drain valves are opened and the exhaust gases are exhausted in the fourth cycle of the engine, while the volumes of the combustion chambers are reduced to min-size. In the extreme upper position, the exhaust valves are closed and the intake valves open. A new engine cycle begins. The number of cylinder pairs (number of rows) can be 3,4,5,6, ..., but with 9TOM it is necessary to shift the cycle of each row, relative to all the others, by the corresponding angles so that there are no two

identical phases (measures) in any “section upeitemi. This will achieve good torque uniformity. The rotational speed from the FISHES to the motor shaft is transmitted using bevel gears, which can reduce yraovyo speed (and if it is bypassed and increase it), the speed of the engine is relative to the ratio of the crank, i.e. a gearbox is integrated in the engine itself.
