Description

1 CS 277193 B6

Double-acting cylinders and pistons are currently being used by two-stroke internal combustion engines whose distribution is formed by channels and pistons. In some dual strokes, for example, Junkers airplanes and DE 28 45 845, counter-moving pistons are used in which the plurality of working area "P1" of the pistons from the total average internal surface area "P2" of the work chamber walls are large. wherein the value of "P2" is given by the average of the maximum value "P2" at the end of the working stroke and from the minimum value "P2" at the start of the working stroke, when the values of "P2" represent the surface measure of the surface of the compression chamber walls. Relationship P1: P2 = P indicates the size of the area utilization of the fuel mixture and the approximate efficiency of the engine and thus its fuel economy.

Two-stroke engines have the advantages described above, especially imperfect suction and exhaust and excessive air pollution.

These drawbacks are eliminated by the four-stroke version of the double-acting cylinder combustion engine and the twin-acting twin-acting double-cylinder cylinder, which permits the application of the rotary engine. An exemplary embodiment of a four stroke combustion engine with a piston motion is shown in FIG. 21 in a cross section, FIG. 22 in a cross section, FIGS. 1 to 8 and 11 to 18 show the operation of the engine, FIG. Fig. 10 shows a blade in a cross section; Fig. 19 shows a motor with eight blades in two motor cylinders; Fig. 20 shows a motor with twelve blades in four 'connected the engine rollers provided, and FIG. 23 shows a gearwheel.

According to the figure, a four-stroke rotary internal combustion engine with a rotary counter-movement of the pistons consists of a motor cylinder 12 in which the shaft 17 is attached to the turntable, which is connected to a fixed ring 16, on which the first blade 1a of the third blade 3 is fixed. the second blade 2 and the fourth leg 4 are fixed to the rotary ring 15, which is fixedly connected to the crank 19, which is connected to the crank mechanism 33 via the connecting rod 29 and via the second pivot 27 and at the front 13 a gear 34 in which a drive gear 24 is mounted on the crankshaft 25, which is coupled to the gearwheel 20 via a pinion gear 23. it has a twin diameter of the toothing wheel 24 and is rotatably mounted on the shaft 17, which is connected to the crank 18, which is connected through the first connecting rod 28 and through the first pivot 26 to the crank shaft 25. In the engine cylinder 12, the first vane 1 and the second vane 2 form the chamber 6, the second vane 2 and the third vane 3 form the third chamber 7, the third vane 3 and the fourth vane 4 form the fourth chamber 8 and the fourth vane 4 and the first vane 1 form first chamber5. All chambers are closed from the front by the front face 13.a from the rear side by no face 14, in which they are made at 90 ° distances in the center of each chamber, the suction opening and in the direction CS 277193 B6 2 from the center above it the exhaust opening 10. For storage In the sealing rings 37, a circular groove is not formed on the outer side of any face 14, the first under the suction openings 9, the second under the exhaust openings 10 and the third above the exhaust openings 10, Fig. 23. An exhaust chamber 22, which is identical in shape and position to the exhaust opening 10, is made 90 ° in the direction of rotation, which is identical in shape and position to the suction opening 9, with the front face of the timing gear 20 being closely touches any face 14 and the rear face of the timing gear 20 is in close contact with the annular outlet a suction line 21 into which the suction slot 21 and the concentric annular outlet of the exhaust manifold 36 open, into which the exhaust slot 22 opens. For clarity they are not drawn in the outlet of the suction line 35 and of the exhaust pipe 36 and on the latter. on the side of the no-end contacting face 14 for the sealing rings 37 on the side of the timing groove wheel 20.

Replace the double-acting manifold - simultaneously for suction and exhaust - with a single-acting intake manifold on the front face13 and another single-acting manifold for the exhaust on the rear face 14 (not shown).

For each half-shaft of the crankshaft 25, a single-stroke in each of the four chambers takes place so that in the opposite chambers, there is a single stroke. in both the first chamber 5 and the third chamber 7, the space is increased and the space is reduced in the adjoining chambers, for example the second chamber 6 and the fourth chamber 8, thereby sucking in, compressing, working and exhausting the two turns of the shaft 25 and that the individual bars, for example suction, are repeated in one direction in the adjoining chamber in which the suction opening 2 with the rotating suction slot 21 - marked by intermittent hatching - in the cogwheel 20, which during the stroke will make the fourth turn. The suction lift is shown in Fig. 12 in the first chamber 5, in Fig. 14 in the second chamber 6, in Fig. 16 in the third chamber 7 and in Fig. 18 in the fourth chamber 8 and the exhaust stroke shown in Fig. 12. in the second chamber 6, in Fig. 14 in the third chamber 7, in Fig. 16 in the fourth chamber 8 and in Fig. 18 in the first chamber 5, the work of this engine is the same as that of the currently used four stroke cylinder.

FIG. 19 depicts an eight-blade rotary engine which is assembled from a common crankshaft 25 having two opposing pins, for two connecting rods the control vanes in the first motor cylinder 12, and on the crankshaft 25 there are two opposite pins displaced by 90 ° for the two connecting rods controlling blades in the second engine cylinder 12., the engine operates as the currently used four-stroke engine.

In order to achieve maximum area utilization of the "P" burned drive pressure and thus the maximum thermal efficiency or economy of the engine, the engine shown in Fig. 20 is formed, consisting of four motor cylinders 12 coupled leading to a self-square, wherein at the junction of the two a rectangular opening is formed in the co-located motor rollers 12 (
