[0057] The forced conduction valve is closed and the air intake control valve is kept open, so that high-pressure air can fully enter the explosion chamber. After the air intake control valve is also closed, the fuel inlet device sprays fuel into the explosion chamber, and the lighter ignites the fuel in the explosion chamber to ignite and explode. The explosion gas drives the first pneumatic motor and the second pneumatic motor in turn, and the second pneumatic motor drives the air compression component to output compressed air to the high-pressure air chamber to maintain pressure.
[0058] The air pressure in the explosion chamber gradually decreases, and the exhaust cam opens the forced conduction valve to discharge the remaining exhaust gas. Before the exhaust cam closes the forced conduction valve, the intake cam opens the intake control valve to allow the high-pressure air in the high-pressure air cavity to press the remaining exhaust gas out of the explosion chamber. Then the forced conduction valve closes and the intake control valve remains open, entering a cycle operation.
[0059] The output shaft one or the output shaft two together with the double-output shaft motor drives the total power output shaft to rotate.
[0060] Compared with the prior art, the present invention has the following beneficial effects:
[0061] The present invention drives the air compression component through the second pneumatic motor, compresses the air using the exhaust gas energy, and delivers the high-pressure air to the combustion chamber, thereby improving the combustion efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0130] Embodiment 5:
[0131] Based on Example 4, the end of the output shaft 23 or the output shaft 24 away from the transmission gear 83 passes through the cylinder body and is connected to the clutch 106. The clutch 106 is then connected to the dual-output shaft motor 107, the clutch 2 108, and the total power output shaft 109 in sequence. The total power output shaft 109 is mounted through a seat bearing.
[0132] Specifically, the double-output shaft motor 107 is a three-phase variable frequency asynchronous motor, which is convenient for electronic control. The double-output shaft motor 107 is powered by a battery or a power grid.
[0133] Specifically, the total power output shaft 109 is provided with a Hall element to detect the rotation speed.
[0134] Among them, the clutch is used to prevent overload.
[0135] Working principle:
[0136] During startup, the dual-shaft motor 107 drives the output shaft 1 23 or the output shaft 2 24 to rotate, and the exhaust cam 81 and the intake cam 82 are rotated through the transmission gear set, and the forced conduction valve 50 is periodically opened. The first pneumatic motor sucks the combustion chamber 10 to a negative pressure, and the normal pressure intake valve 60 is opened, so that the airflow drives the second pneumatic motor, so that the air compression component compresses the air and outputs it to the high-pressure air chamber 42. When the pressure in the high-pressure air chamber 42 is greater than the constant pressure valve 47, the gas in the high-pressure air chamber 42 enters the combustion chamber 10 when the intake control valve 70 is opened. Since the opening state of the normal pressure intake valve 60 and the opening state of the intake control valve 70 overlap, the gas in the high-pressure air chamber 42 enters the combustion chamber 10. In this process, the output power of the dual-shaft motor 107 is significantly lower than the power when the constant pressure valve 47 is closed, and the control system enters the ignition state through this power change.
[0137] The forced conduction valve 50 is closed and the intake control valve 70 is maintained open, so that high-pressure air can fully enter the explosion chamber 10. After the intake control valve 70 is also closed, the fuel inlet 11 sprays high-pressure oil mist into the explosion chamber 10, and the igniter 12 ignites the oil mist in the explosion chamber 10 to ignite and explode. The explosion gas opens the high-pressure valve 13 and enters the first air intake channel 25, pushing the pneumatic gear 1 21 and the pneumatic gear 2 22. The explosion gas is reduced from high-pressure gas to medium-pressure gas and enters the second air intake channel 35, pushing the pneumatic gear 3 31 and the pneumatic gear 4 32, and driving the air compression component to output compressed air to the high-pressure air cavity 42 to maintain the pressure. The medium-pressure gas is reduced to low-pressure gas and enters the fourth air intake channel 95, pushing the pneumatic gear 5 91 and the pneumatic gear 6 92, and driving the energy recovery device 102 to generate electricity and store the electrical energy in the battery. The low-pressure gas is converted into exhaust gas and discharged through the purifier 101.
[0138] The air pressure in the explosion chamber 10 gradually decreases, and the remaining exhaust gas cannot open the high-pressure valve 13. The exhaust cam 81 will open the forced conduction valve 50 to discharge the remaining exhaust gas. Before the exhaust cam 81 closes the forced conduction valve 50, the intake cam 82 will open the intake control valve 70, so that the high-pressure air in the high-pressure air cavity 42 will press the remaining exhaust gas out of the explosion chamber 10. Then the forced conduction valve 50 is closed and the intake control valve 70 remains open, so that the high-pressure air can fully enter the explosion chamber 10. After the intake control valve 70 is also closed, the fuel inlet 11 sprays high-pressure oil mist into the explosion chamber 10, and the igniter 12 ignites the oil mist in the explosion chamber 10 to ignite and explode, and then enters a cycle operation.
[0139] When the amount of electricity stored in the battery reaches the set high-voltage threshold, charging stops, and the frequency of the inverter is adjusted to drive the dual-output shaft motor 107 according to the total power output shaft speed measured by the Hall element on the total power output shaft 109 to release the electrical energy in the battery. At this time, the dual-output shaft motor 107 and the internal combustion engine drive the total power output shaft 109 at the same time. After the battery electricity drops to the low-voltage threshold, the dual-output shaft motor 107 is powered off and switched to a fully fuel-powered starting state.
[0140] The clutch may also be an electromagnetic clutch capable of active control, so that the dual-shaft motor 107 is disconnected from the total power output shaft 109 during startup, and all energy is used to start the internal combustion engine. After the internal combustion engine is started, the dual-shaft motor 107 is connected to the total power output shaft 109 to output power.

10. A method for using a gear motor type internal combustion engine, characterized in that: The following steps are involved: The end of the output shaft 1 or the output shaft 2 away from the transmission gear 1 is connected to the double-output shaft motor, and the double-output shaft motor is connected to the total power output shaft; When starting, the double-output shaft motor drives the output shaft 1 or output shaft 2 to rotate, and the exhaust cam and the intake cam rotate through the transmission gear set, and the forced conduction valve is opened periodically. The first pneumatic motor sucks the explosion chamber to negative pressure, and the normal pressure intake valve opens, so that the air flow drives the second pneumatic motor, so that the air compression component compresses the air and outputs it to the high-pressure air chamber; When the pressure in the high-pressure air chamber is greater than the constant-pressure valve, the gas in the high-pressure air chamber enters the explosion chamber when the intake control valve is opened. The opening state of the normal-pressure intake valve and the opening state of the intake control valve overlap for a period of time, and the gas in the high-pressure air chamber enters the explosion chamber. In this process, the output power of the dual-output shaft motor is lower than the power when the constant-pressure valve is closed, and the control system enters the ignition state through this power change. The forced conduction valve is closed and the air intake control valve is kept open, so that high-pressure air can fully enter the explosion chamber. After the air intake control valve is also closed, the fuel inlet device sprays fuel into the explosion chamber, and the lighter ignites the fuel in the explosion chamber to ignite and explode. The explosion gas drives the first pneumatic motor and the second pneumatic motor in turn, and the second pneumatic motor drives the air compression component to output compressed air to the high-pressure air chamber to maintain pressure. The air pressure in the explosion chamber gradually decreases, and the exhaust cam opens the forced conduction valve to discharge the remaining exhaust gas. Before the exhaust cam closes the forced conduction valve, the intake cam opens the intake control valve to allow the high-pressure air in the high-pressure air cavity to press the remaining exhaust gas out of the explosion chamber. Then the forced conduction valve closes and the intake control valve remains open, entering a cycle operation. The output shaft one or the output shaft two together with the double-output shaft motor drives the total power output shaft to rotate.
