Abstract

The invention allows to improve the power and economic performance of the engine. The main combustion chamber 6 (CS) is bounded by the wall of cylinder 1, its head 3 and the notch in the bottom 8 of the piston 2 and is equipped with a deflector 9 rigidly connected to the head. Additional CS 7 is made in the latter, it has a fuel nozzle 10 and communicates with CS 6 through a tangential connecting channel 11 located opposite the deflector 9, b1 filled with a cavity-cavity 12, coaxially to the channel 11. Deflector m. it is provided with a tide 14, which limits channel 11 and a symmetrical deflector 9 relative to the plane passing through the valve axis. The ignited fuel, flowing out at high speed through channel 11, hits the cavity-cavity 12 and generates a high-power acoustic field with constant parameters independent of the position of the piston 2 relative to the head 3. This allows the fuel to be intensified during whole burning process. The rod 13 helps to increase the power of the acoustic floor. 2 hp f-ly, 3 ill. (t (L

holds cylinder 1 with piston 2, cylinder 3 cylinder 1 and inlet 4 and exhaust 5 valves installed in cylinder 3, as well as main 6 and additional 7 combustion chambers.

The main combustion chamber 6 is bounded by a wall of the cylinder 1, its head 3 and a recess in the bottom 8 of the piston 2 and is provided with a deflector 9, which is rigidly connected to the cylinder rojioBKoti.

An additional combustion chamber 7 was made in the cylinder head 3 .1, equipped with a fuel nozzle 10 and communicated with the main combustion chamber 6 through a tangential connecting channel 11 located opposite the deflector 9, made with a cavity-cavity 12, coaxially with the connecting channel 11.

The deflector 9 can be provided with a rod 13 placed in the connecting channel 11. The head 3 of the cylinder 1 can be equipped with a tide 14 defining the connecting channel 10 and a symmetrical deflector 9 relative to the plane passing the valve axis 15.

The internal combustion engine works as follows.

The ignited fuel supplied by the nozzle 10 to the additional combustion chamber flows out at high speed through channel 11, hits the cavity-cavity 12 of the deflector 9 opposite the opening of the connecting channel 11, and generates a high-power acoustic field with constant parameters. To improve the mixing of the air / fuel mixture in the main combustion chamber during the combustion process, the deflector

9 VI connecting channel 1 1 can be made in the tides of the cylinder cover, which serve to form vortex zones in the area of gas distribution valves 4 and 5 when the fuel-air mixture flows from the additional chamber 7 to the main combustion chamber 6. To increase the power of the acoustic field, a rod 13 can be used, which is connected to the connecting channel 11.

Due to the fixed location of the cavity-resonator 12 in the defacoustic

the fields are constant and do not depend on the position of the piston 2 relative to the head 3 of the cylinder 1, which allows to intensify the process of burning the fuel throughout the entire combustion process.
