[0042] Working process: Taking a four-cylinder engine as an example, the motor starts the air compressor to compress air into the air tank. One end of the air pipe is connected to the exhaust port of the air tank, and the other end is connected to the air inlet 21 of the compressed air engine air storage chamber. The compressed air enters the cylinder air intake chamber 20 and the cylinder intake hole 11. The cylinder intake valve 9 rotates to the highest point through the intake cam on the camshaft 13 to drive the intake rocker arm 15-1 on the rocker shaft 14 to open. The compressed air instantly explodes into cylinder 1 and cylinder 4, pushing the piston 8 and connecting rod 7 to rotate the crankshaft 6. Then the intake of cylinder 1 and cylinder 4 pushes the piston 8 to the bottom dead center of the cylinder, and the exhaust cam on the camshaft of cylinder 2 and cylinder 3 rotates to the highest point to drive the exhaust rocker arm 15-2 to open the cylinder exhaust valve 10 in advance, so that the compression of cylinder 2 and cylinder 3 The compressed air is compressed and recovered from the cylinder exhaust hole 12 through the air pipe to the air storage tank for reuse; when the piston 8 of cylinder 2 and cylinder 3 reaches the top dead center of the cylinder, the intake cam on the camshaft 13 rotates to the highest point to drive the intake rocker arm 15-1 on the rocker shaft 14 to open the closed cylinder intake valve 9, and the compressed air instantly explodes into cylinder 2 and cylinder 3 to push the piston 8 and connecting rod 7 to rotate the crankshaft 6, and then the piston 8 of cylinder 2 and cylinder 3 reaches the bottom dead center of the cylinder, and the exhaust cam on the camshaft of cylinder 1 and cylinder 4 rotates to the highest point to drive the exhaust rocker arm 15-2 to open the cylinder exhaust valve 10 in advance, and the compressed air of cylinder 1 and cylinder 4 is compressed and recovered from the cylinder exhaust hole 12 through the air pipe to the air storage tank for reuse; the working motion is circulated in sequence.

[0043] Reference Figure 9 Taking two new compressed air engines as an example, the exhaust of the new compressed air engines is compressed, recovered and reused for continuous power generation to implement the operation process.

[0044] The air compressor 32 is powered on, and compressed air enters the first air tank 34 through the first air pipe 33. The compressed air in the first air tank 34 has a pressure of approximately 1.3 MPa. The compressed air then flows through the second air pipe 35 to drive the first air engine 36, which then drives the first generator 37 to generate electricity. Simultaneously, the first air engine 36 compresses the exhaust gas, which is then recycled through the third air pipe 38 and sent to the second air tank 39. The compressed air in the second air tank 39 has a pressure of approximately 1.1 MPa. This compressed air then drives the second air engine 41 through the fourth air pipe 40, which then drives the second generator 42 to generate electricity. The second air engine 41 further compresses the exhaust gas, which is then recycled through a pipe into the third air tank. The compressed air in the third air tank has a pressure of approximately 0.9 MPa, which then drives the third air engine to generate electricity. The continuous generation mode of the compressed air engines is determined by the pressure difference of the recovered compressed air. The higher the starting pressure, the more air engine generator sets are required. This multiple compressed air engine generation mode can greatly improve the efficiency of compressed air power generation.

[0045] The novel compressed air engine described in the present invention uses compressed air entering the cylinder through the air storage chamber, and adopts the interaction of cam, rocker arm, regulating rod and valve to make the engine asynchronous crankshaft, cylinder, connecting rod and piston work in sequence, pushing the piston upward to compress the exhaust gas in the cylinder and enter the air storage tank for reuse, so that the compressed air drives the air engine piston and asynchronous crankshaft to work stably. The engine has the advantages of strong explosive force, high torque, low construction cost and power generation cost, stable power generation, high power generation efficiency, low energy consumption and environmental protection, and can be widely used in various industries such as transportation vehicles, ships, electric air generator sets, compressed air power station generator sets, etc.
