Description

INTERNAL - COMBUSTION ENGINE
The present inventions are united by the common inventive conception and related to machine- building, especially to internal combustion engines and can be used in an automobile industry, tractors, helicopters, home machinery and power industry and etc. The internal combustion engine, by the patent GE P3515B (published 2005-05-
10, bulletin 9), being much more closely to the present invention by the main features is chosen as prototype. It includes shaft, rim with running track of an elliptical form, cylinders, radial coming together by upper parts, connecting -rods with pinch rolls, contacting with running track of the rim. The prototype has low efficiency and durability, more over its work isn't enough smooth. These disadvantages are conditioned by the following circumstances. Firstly, the compression ratio in combustion chambers of the said engine is constant and there isn't possibility to control it when working and to optimize it depending on the engine load and rotating speed of the main shaft. At this possibility the engine would be more economic and durable. Secondly, in the said engine the coupling rods (connecting- rods) with pinch rolls, arranged on them, move in straight lines and at interaction with rim, the forces, creating the torque strength have a little value because of the little value of resultant force projection to tangential force, .working on rim. By this reason there is the loss of gas pressure force from gas mixture combustion, especially when the gas pressure on piston is at the most, and the coupling rod is at the right angle to tangent to ellipse. In the third place, when prototype working there is intermittence of man power action, creating the torque strength.
The mentioned inventions, united by the common inventive idea -are aimed at increase of efficiency, softness and durability at the expense of: 1) making possible to control the compression ratio in combustion chambers of cylinders by correction of piston stroke and arrangement of top dead center in combustion chambers depending on engine drive shaft loading, and also its rotational speed and octane number of used fuel; 2) selection of optimal pressure angle of pinch rolls for creation the effective torque strength and decrease of friction loss; 3) lapping of pistons travel phase, providing continuity of man power action, creating torque strength.
Accordingly to the first variant (by the first independent claim) in internal combustion engine, including rim, installed with possibility of rotation, and having orbital running-tracks in the form of T-shaped groove of oviform or another, secluded and centrosymmerrical form, embraced by these running-tracks non rotating block of cylinders, radial coming together by combustion chambers and having pistons inside, and also there are connecting-rods, hingedly connected with cylinders and with arranged on cylinder block one-armed levers, where the connecting-rods have pinch rolls on the other ends, contacting with running- tracks of the mentioned groove, accordingly to invention the non-rotating cylinder block is arranged with possibility of operated displacement from the axis of rim rotation, the engine is provided with means for realization of this displacement, when making engine with four-stroke cycle of action, the hackles at orbital running-tracks are carried out even-numbered; the number of cylinders is odd-numbered and more than number of hackles.
In accordance with the second variant of the invention( by the fourth independence claim) in the internal combustion engine, including non-rotating rim with orbital running-tracks in the form of T-shaped groove of oviform or another, secluded and centrosymmerrical configuration, embraced by these running-tracks non rotating block of cylinders, radial coming together by combustion chamber and having pistons inside, and also there are connecting-rods, hingedly connected with cylinders and with arranged on cylinder block one-armed levers, where the connecting-rods have pinch rolls on the other ends, contacting with running- tracks of the mentioned groove, accordingly to invention the non-rotating rim is arranged with the possibility of synchronous, plane-parallel transfer by cycle in diameter less than piston stroke and with rotating speed of cylinder block, besides the engine is provided with the means for this transfer; when making the engine with four-stroke cycle of action, the hackles at orbital running-tracks are carried out even-numbered; the number of cylinders is odd-numbered and more than number of hackles. There is a following cause-and-effect relation between distinctive features and the achieved result.
The possibility of operated cylinder block displacement from axis of rim rotation makes possible to correct (for example, from airborne computer of carrier or electric power installation) the piston stroke and arrangement of top dead center in combustion chambers depending on engine drive shaft loading, its rotational speed and octane number of used fuel. It is known that by operation of compression ratio is achieved increase of efficiency, durability and saving of fuel.
The installation of non-rotating rim with the possibility of synchronous, plane- parallel transfer allows to choose the constructively optimal calculated pressure angles of pinch rolls, where, depending on curvature of work surface of running- track there are maximal forces, realizing useful torque strength. For all that, for supply the efficiency this transfer must be by circle and at aped equal to rotating speed of cylinder block (synchronizm). The value of the circle diameter of the said transfer mustn't be more than piston stroke.
The execution of engine with odd-number of cylinders, which is more than quantity of hackles at running-tracks of the rim, provides the continuity of torque strength action, got from the piston pressure with pinch rolls and softness of engine work. The mentioned totality of main features, characterizing variants of engine from the state of art is unknown and doesn't obviously come from it. Only availability of distinctive features in this invention allows to achieve the aimed result.
The essence of invention is explained by diagrammatic drawings, where there are shown: Fig. 1- engine with non-rotating block of 3-cylinders and rotating rim with oviform of ( 2-hackled) running-track by the first variant of invention.
Fig. 2-engine with non-rotating block of 5- cylinders and rotating rim with epitrochoid form of ( 4-hackled) running-track by the first variant of invention.
Fig. 3- engine with rotating block of 4- cylinders and non-rotating rim with elliptical form of ( 2-hackled) running-track by the second variant of invention.
Fig. 4- engine with rotating block of 4- cylinders and non-rotating rim with epitrochoid form of ( 4-haclded) running-track by the second variant of invention. The engine by the first variant includes the rim 1, arranged with possibility of rotation ,having T-shaped groove 3 of oviform or epitrochoid (relating to axis 2 of rim rotation) with running tracks. The cylinder block 4 with combustion chambers 5 is installed without possibility of rotation, but can be transferred in frontal plane( at the right angle to axis 2 of rotation). For this transfer (preferably along one of cylinders) the engine is provided by mechanical means 6 as screw or clowning, controlled by airborne (isn't shown in the picture). Pistons 7 are installed in cylinder block 4 with the possibility of back-and-forth motion. With them, by the aid of hinge 8 are connected the connecting rods 9, on the other ends of which are installed the pinch rolls 10. These rolls 10 are in a work contact with running- tracks of T-shaped groove 3. The connecting-rods 9 are maintained in on-position by one-armed levers 11, installed by hinge 12 on cylinder block 4. The rim is provided with gear ring 13 for engagement with starter (isn't shown in the picture) of the engine at starting. Number of cylinders in this variant is one more than number of hackles in running-track of rim 1.
In the engine by the second variant of invention the rim 1 is arranged without possibility of rotation, but with possibility of synchronous, with speed of rotation of cylinder block, plane-parallel transfer of its each point, for example, point 14 by circle in diameter D. For this transfer the engine is provided by gear ring with spurious gear wheel 15, engaged with coaxial fixed and equal to number of teeth wheels 16 and 17, made on the cylinder block 4 and on supplementary shaft 18. Supplementary journal 19 of shaft 18 is the configuration center of running-track of the rim 1 and its essentricity /^ equal to the half of circle D of plane-parallel transfer of the rim 1, and at that constructively it is less than piston stroke 7, but in the condition of geometrically optimal angular influence of pinch rolls 10 upon the running-track of T-shaped groove 3 for to reach the maximal torque strength. The engine by the first variant works in the following way. With the aid of starter the rim 1 is twisted for the engine starting. The well- known systems of gas mixture supply, the ignition and gas distribution (isn't shown in the picture) provides the starting and work of engine. At that the pistons 7 make forced alternate-reciprocal motion, that is provided by the well- known 2-stroke and 4-stroke cycle of engine work and by running-tracks of T- shaped groove 3. The pinch rolls 10 weigh upon the curved surface of the running-tracks of T-shaped groove and create tangential force, which is the result from the explosion of gas mixture in combustion chambers 5 of cylinders , that creates engine torque strength. At this, the cylinder block 4 is kept without possibility of rotation. During the engine work, by the operation of screw-gear 6 the cylinder block is displaced about the axis 2 of rim rotation, that means approaching or moving off to its running-tracks of effective area of pinch rolls 10 and therefore is transferred the area of piston stroke 7 in combustion chamber 5 of cylinders, that causes the displacement of the dead point. These displacements are comparatively not so much, but enough for by this way, depending on the external engine load, speed of rotation of engine drive shaft and octane number of the used fuel, to operate the compression ratio in the range from 7 to 13, and in the result to increase the efficiency owing to fuel economy.
The engine work by the second variant is the same, differing so that the rim 1 is held without possibility of rotation, but the cylinder block rotates. The rotation from the cylinder block 4 by means of wheel 16 and spurious gear 15 is delivered to wheel 17 and supplementary shaft 18, by shaft journal of which is placed geometrical center of running-track of the rim 1. In the result, at engine working and the cylinder block 4 rotation, the rim 1 makes the plane - parallel transfer(without rotation), its each point moves by circle in radius Δ or diameter D. This movement is synchronous with cylinder block rotation 4 and provides necessary displacement of curved surface of the rim 1 running-tracks and optimal, in the view of receiving the maximal torque strength, the angles of interaction with pinch rolls, arranged on connecting-rods 9. The made pre-production models demonstrated the effectiveness of these constructional features for to achieve the problem put by.
