Description

The invention relates to mechanical engineering, in particular to engine building. The proposed engine can be used in the automotive industry, shipbuilding and other industries where energy conversion is required.

To date, the most common are four-stroke reciprocating internal combustion engines. Rotary piston engines, including the F. Wankel engine, are less common. The principle of operation of the four-stroke piston engine E. Langen and N. Otto - K. Benz - R. Diesel is disclosed in the work of V.K. Vakhlamov, M.G. Shatrov, A.A. Yurchevsky "Automobiles. Theory and design of the car and engine" . (Moscow. "Academy" 2005). The cylindrical piston reciprocates within the liner (open on the crankshaft side and closed on the opposite), which is part of the engine housing. The piston is connected by a connecting rod with a crankshaft. During the movement for two turns of the crankshaft, it occurs sequentially: the intake (intake) of the working mixture (gasoline, gas, diesel fuel, etc. with air), the compression of the working mixture, the ignition of the working mixture - working stroke, exhaust gas exhaust. This is the duty cycle of the engine.

A description of the engine of F. Wankel is set forth in the work of G. S. Majug and V. Kh. Poidnitsa "Rotary piston internal combustion engines" (Moscow. "Knowledge". 1964). A trihedral rotor rolls around a stationary gear wheel, mating with it with an toothed rim, while the vertices of its angle move along the epitrachoid. The working cavity of the housing has the form of two mating cylinders. When the rotor rotates between the walls of the housing and the faces of the rotor, a sequential change in the volumes occurs four-stroke engine processes occur sequentially.

The closest analogue of the invention is a rotary-pulse internal combustion engine containing two pairs of pistons enclosed in a shell that rotate on a common shaft from ignition of the combustible mixture between the pistons, the transmission of torque from which is carried out by two gears, which allow transmitting torque in accordance with the piston cycle, this torque is transmitted to the drive by gearing (see patent RU 2292470 C2, F02B 53/00, 01/27/2007, 6 p. (1)).

The technical result of the invention is to increase the efficiency and simplify the design of the engine.

The technical result is achieved by the fact that a rotary-pulse internal combustion engine containing two pairs of pistons enclosed in a shell rotating on a common shaft from ignition of the combustible mixture between the pistons, the transmission of torque from which is carried out by two gears, allowing to transmit torque in accordance with the piston cycle , while the torque is transmitted to the drive by gearing, characterized in that the pistons are V-shaped, the shell is cylindrical, one of the gears of the cylinder rim, and the second component of the two halves of the cylindrical gear connected by two rails so that the number of teeth of the cylindrical part and rectilinear are equal.

Figure 1 shows one working stroke with one working chamber.

Figure 2 shows one working stroke with two working chambers.

Figure 3 in the upper and lower parts of the sheet shows the nodes of the transmission of torque, in the center - spark plug, main drive shaft, outer shell, cooling jacket, inner shaft.

Figure 4 shows the pistons on the inner shaft, the outer shell, spark plug, cooling jacket, components inlet and outlet components with an indication of the direction.

The proposed engine consists of two rings with two pistons fixed to each of them. Each piston is a prism in the cross section of which is a 60-degree annular sector. Pistons are located diametrically on the ring. When assembling, the pistons of one ring enter the space between the pistons of the other. Moreover, each of the rings can rotate relative to the other by an angle of 60 degrees. Together, both discs are mounted in a cylindrical shell and on one hollow shaft. When one of them rotates relative to the other, expansion occurs in the two chambers between the pistons, and compression in the other two. In one (or two - depending on the possibilities of heat removal) from the compressible chambers, the working mixture injected in the previous cycle is ignited. There is a working stroke. The remaining cycles are quite fully indicated in Fig. 1 for an engine with one working chamber and in Fig. 2 for an engine with two chambers.

To transmit the torque in the required cycle from the piston disks to the main drive shaft, two torque transmission units were used.

The torque transmission unit is an oval gear consisting of two halves of a cylindrical gear connected by two gear racks, the number of teeth of the semi-gears and the racks is the same. When the rack is engaged, the oval gear moves progressively, when the half gear rotates from the gear connected to the disk and transmits rotation to the shaft of the main drive. During the translational movement, the oval gear prevents the rotation of the associated pair of pistons in the opposite direction.

Compared to the analogue, the design is simple and improves the quality of the working mixture due to additional purge of the combustion chambers after the working stroke.

Materials for the manufacture of the main engine parts: alloyed silumin for pistons and disks (which are a single unit), alloyed steel for shafts and gears, cast iron for the body of the cooling jacket.

Work environment - atmosphere.

The design of the proposed engine solves the following main tasks:

- increase useful work per unit of fuel (additional ventilation of combustion chambers);

- reduction of friction losses (lack of plain bearings);

- simplification of production, repair and maintenance (simplicity of design).
