Description

2. The engine according to I. 1, about t l and the fact that the cap from the side of the piston is made with a conical chamber, the larger diameter of which is equal to the diameter of the cylinder. 3. The engine for PP. 1 and 2, in that the intake and exhaust ports are parallel to the axis of the cylinder. 4, Engine on PP. 1-3, which is connected with the fact that the compressor discharge cavity communicates with the cylinder sub-piston cavity.

The invention relates to mechanical engineering, in particular to engine-building, and can be used in two-stroke engines of internal combustion with supercharging. Known two-stroke engines of internal combustion with supercharging, containing at least one cylinder with a piston and cylinder head, in the inlet and outlet channels of which are located valves, a compressor with a pressure cavity and a cylinder block with a piston chamber lj. However, in such a design of the engine, in order to ensure high quality of the purge, it is necessary that the ratio of the piston stroke to the diameter of the cylinder be sufficiently high, which ultimately increases the size and weight of the engine. The purpose of the invention is to improve the quality of the purge. This goal is achieved by the fact that in a two-stroke engine of internal combustion with supercharging, containing at least one cylinder with a piston and cylinder cylinder, in the intake and exhaust channels of which are located valves, a compressor with a pressure cavity and a cylinder block with a piston chamber, a cover with The side of the piston is made with a baffle located between the valves. On the side of the piston there is a bit on the side with a conical chamber, the larger diameter of which is equal to the diameter of the cylinder. The intake and exhaust ports are parallel to the axis of the cylinder. The compressor cavity is in communication with the cylinder piston cavity. FIG. 1 is a schematic diagram of the engine J in FIG. 2 is a section of the engine along the axis of the cylinder in FIG. 3 is a diagram of the circulation of gases in the cylinder; FIG. A is a diagram of the movement of gases in a cylinder with the intake valve open. The engine contains at least one cylinder 1 (FIG. 1) with piston 2 and cover 3 of cylinder 1, in inlet 4 and outlet 5 channels of which valves 6 and 7 are located, compressor 8 with discharge cavity 9 and block 10 of cylinders 1 with piston chamber 11. Krischka 3 on the piston 2 side is made with a deflector 12 placed between valves 6 and 7. On the piston 2 side, the cap 3 is filled with a conical chamber 13, the larger diameter 14 of which is equal to the diameter of the cylinder 1. The inlet 4 and outlet 5 are parallel to the axis cylinder 1. Compressor 8 injection cavity 9 with communicated with the piston cavity 11 of cylinder 1. The pressurization unit consists of a compressor 15 connected kinematically to a gas turbine 16. When the engine is operating, the exhaust gases through valve 7 (Fig. 1) and exhaust channel 5 are diverted to a gas turbine 16. Gas turbine 16 drives a high pressure compressor 15. Compressor 15 supplies compressed air through inlet channel 4 through valve 6 to cylinder 1. In cylinder 1 (Fig. 2), compressed air, interacting with deflector 12 of cover 3, is deflected towards piston 2. Simultaneously in piston cavity 11 (Fig. ) cylinder 1

using the compressor 8 with a cavity; The 9th thrust produces a pressure that relieves the piston 2. As a result, the lubrication of the cylinder and the piston is improved. With the valves 6 and 7 open (FIGS. 3 and 4), due to the deflector 12 of the valve shaft 3 and the conical chamber 13, high pressure air blows through

the entire volume of cylinder 1 between krSh1ky 3 and piston 2.

Thus, the proposed construction of a conical chamber, a deflector and communication of the injection cavity, a compressor with a sub piston cylinder cavity allows to significantly improve the quality of the cylinder purge.
