Abstract

FIELD: engine devices and pumps.

SUBSTANCE: when a single-stroke engine with an external combustion chamber is running, a portion of the air, compressed in the compressor cavities, enters it. At the same time, the engine control system opens the air inlet valve from the compressor cavities of the engine to the turbine. After the turbine, the air is released into the atmosphere. The turbine drives the electric generator. The electric generator of the engine can operate continuously or periodically for charging / recharging the battery.

EFFECT: improved conversion efficiency.

The invention provides an increase in specific power, efficiency of the energy module, as well as multi-fuel.

OBJECT OF THE INVENTION

The purpose of the invention is to provide the engine with its own source of electricity.

SUMMARY OF THE INVENTION

The invention is illustrated by the description of the principle of operation of a single-cycle engine with an external combustion chamber - hereinafter the engine. It acts as follows. When starting the engine, the control system (see drawing) supplies a dose of fuel to the external combustion chamber 1 with nozzle 2 and ignites it with a spark plug 3. The fuel burns and if the piston group of a single-cycle engine consisting of pistons 4 and 5 is in the position as shown in the figure , then the combustion products from the external combustion chamber 1 through channel 6 through the open valve 7 enter the lower working cavity of the piston 4. Under their influence, the piston 4, rods 8, 9 and piston 5 begin to move upward. Since the lower surface area of the piston 4 is larger than its upper surface area by the difference in the cross-sectional area of the rods 8 and 9, the pressure of the air compressed in the upper compressor cavity of the piston 4 is greater than the pressure of the combustion products in its lower cavity. Therefore, air from the upper compressor cavity of the piston 4 through the check valve 10 enters the external combustion chamber 1, supporting the combustion process of the fuel supplied by the nozzle 2. Air from the atmosphere is sucked into the lower, compressor, piston cavity 5 through the non-return valve 11, and air (hereinafter exhausted combustion products) is drawn into the atmosphere from the upper piston cavity 5 through the valve 12. The energy of the combustion products through the rod 9 and the connecting rod 13 is transmitted to the crankshaft 14. Upon arrival of the pistons 4 and 5 at the top dead center of movement, the control system puts the valves 7 and valve 12 in the closed position, and the valve 15 and valve 16 in the open position. Now, the combustion products from the external combustion chamber 1 through the channel 17 through the valve 15 enter the upper cavity of the piston 5. The pistons 4 and 5 begin to move downward, and the crankshaft of the engine 14 continues to rotate in the same direction. Compressed in the lower compressor cavity of the piston 5, the air through the check valve 18 enters the external combustion chamber 1, providing combustion of the fuel supplied by the nozzle 2. Air from the atmosphere is sucked into the upper compressor cavity of the piston 4 through the non-return valve 19, and exhaust gases from the lower cavity are emitted through the valve 16 into the atmosphere. In the future, the control system, transferring valves 7, 12, 15, 16 from one position to another, provides rotation of the engine crankshaft in one direction. Valves 20, 21, 22 are used to provide exhaust gas recirculation (Patent No. 2538231), reverse rotation of the crankshaft (Patent No. 2538429) and optimize the expansion of combustion products in the engine cylinder (Patent No. 2543908).

The method of generating electricity by an engine with an external combustion chamber, the energy of the air compressed in the compressor cavities of the pistons is as follows. Under the action of a single-cycle engine, the control system opens the air supply valve from the compressor cavities of the piston group 23. The air compressed in the compressor cavities of the pistons (upper, compressor, piston cavity 4, and lower, compressor, piston cavity 5) enters the turbine 26 through channels 24, 25 and, having worked, it is discharged through channel 27 into the atmosphere. The turbine 26 drives the generator 28 into rotation. The engine generator can operate continuously or periodically to charge / recharge the battery.
