Description

INTERNAL COMBUSTION ENGINE "FZR"

Technical field

The invention relates to the field of mechanical engineering, namely, to internal combustion engines.

State of the art

Known four-stroke internal combustion engine with gas distribution valves of vertical arrangement, acting according to the reciprocating motion (see Yu. I. Borovsky and others. "The device of cars)), M., B. IiI. 1988, p. 12, fig. 1.4, fig. 3.3 and S. F. Demikhovsky et al. “The design and operation of Zhiguli and Moscvich cars M. Iz. DOSAAF. 1988, p. 14, fig. 6), providing periodic connection of the internal space of the cylinders with the exhaust or intake tract or, completely blocking the holes, sealing the cylinders. The engine consists of a crankshaft, connecting rod, piston, cylinder, cylinder block, exhaust and intake tract, camshaft. The camshaft driven from the crankshaft by means of the used drive with its cams, overcoming the efforts of the springs, with the help of pushers provides translational movement of the valves for the timely intake of the combustible mixture into the engine cylinders and exhaust from them.

The disadvantage of these designs is that the existing valves of the gas distribution system do not provide the required clearance through which air, combustible mixture or exhaust gases pass. Valves that perform reciprocating motion with their inertia prevent the engines from accelerating to high revolutions, since at high revolutions the springs do not have time to close the valves torn off the camshaft. And the valve actuator used is the source friction and braking losses, since the springs strongly press the “tails” of the valves to the camshaft cam surface. The closest in technical essence and the achieved technical result is a four-stroke internal combustion engine

5 “Rotating cylinder-valve” of the “RCV Engines” company (Rotaru Sulipder Valve - RCV Еппіпес, see the website for quick-fixes.сom), designed for aircraft models, lawn mowers, hand-held mowers, gas scooters, self-propelled aerial vehicles, scooters, using a cylinder with a hole rotating around its axis. The engine “rotating cylinder - valve” consists of a block and? installed in it with the possibility of rotation around its axis of the cylinder with a fixed gear, an intermediate gear and gear on the crankshaft, providing rotation of the cylinder, as well as from the crankshaft, connecting rod, piston, intake

15 and the exhaust tract.

The cylinder is mounted in the engine block in such a way that when it is rotated, the existing hole on the cylinder coincides with either the opening of the exhaust or intake path, or with the blind part of the block body. At the same time, the drive required for the rotation of the cylinder provides the required

20 the ratio of rotation of the cylinder relative to the crankshaft.

The disadvantage of this design is that the rotation of the cylinder around its axis using bearings is structurally difficult. Shocks obtained during the combustion process cause axial impacts on the cylinder mounted on the bearings.

25 As a result of this, the reliability of the engine is deteriorating, the service life is reduced and, thereby, the use of this design in compact cars is complicated. On the other hand, the drive of individual rotation of the cylinder complicates the application of this design in multi-cylinder engines.

ZO Disclosure of inventions

The problem to which the invention is directed, is to eliminate the above disadvantages and to ensure gas distribution both in single-cylinder and in multi-cylinder engines with lower metal consumption, increased efficiency and toxicity, allowing to improve the performance of internal combustion engines.

5 The above technical result is achieved by the fact that in the internal combustion engine "FZR", consisting of a crankshaft, connecting rod, piston located inside equipped with at least one cylinder bore with gear, cylinder block, intake and exhaust tract, the gear is installed in the zone holes of the cylinder and is made with at least one hole and can rotate around the axis of the cylinder. In one embodiment, the gear is made in the form of a gear hoop with either one hole, and a cylinder with two holes with a horizontal bend, or a gear hoop with two holes, and a cylinder with one hole with a horizontal bend, or

15 the gear hoop is made with one hole, and the cylinder with two holes with a vertical outlet, or the gear hoop is made with two holes, and the cylinder with one hole with a vertical outlet. According to another embodiment, the gear is made in the form of a faceplate or with one hole, and the cylinder with two holes with horizontal

20, either the pinion gear is made with two holes, and the cylinder with one hole with a horizontal tap, or the pinion gear is made with one hole, and the cylinder with two holes with a vertical tap, or the pinion gear is made with two holes, and the cylinder with one hole with a vertical branch.

25 An analysis of the known design solutions showed that the claimed solutions appear properties that do not match the properties of known devices. The above essential features of the proposed rotary valves provide an extension of their field of application by achieving gas distribution with lower metal consumption, its use in both single-cylinder and multi-cylinder engines, thereby increasing efficiency, reducing metal consumption and toxicity to improve the performance of internal combustion engines. Thus, the essential features and technical The result is in a causal relationship.
