Without installing the gearbox, because there is a multi-pole gearbox to control the speed of the main engine pneumatic motor, which also controls the number of air intake and the number of oil injection and ignition, so the engine speed is controlled, and the heavy and complex gearbox of the motor vehicle is not needed, which reduces the weight of the motor vehicle, reduces energy loss and reduces the cost of the motor vehicle.

[0007] The embodiments of the application will be clearly and completely described below with reference to the drawings in the embodiments of the application. Obviously, the described embodiments are only part of the embodiments of the application, not all embodiments. Based on the embodiments in the application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the application.
[0008] It should be noted in the description of the application that the terms "center", "up", "down", "front", "back" and the like indicate the orientation or positional relationship.
[0009] As shown in Figure 1, 2, 3, 8, 9, the application provides an engine comprising: the intake hole 2 of the rotary piston pneumatic motor 1 is connected with the combustion chamber 15. The high-temperature-resistant valve 3 is installed at the combustion chamber 15 and the intake hole 2. The spark plug 6 is installed at the side of the combustion chamber 15. The fuel nozzle 7 is installed at the side of the combustion chamber 15. The combustion chamber 15 is connected with the high-pressure gas cylinder 9. The one-way valve 8 is installed in the connecting pipe. The high-pressure gas cylinder 9 is connected with the high-pressure gas pump 10. The high-temperature-resistant valve shaft is connected with the output shaft of the small multi-pole transmission 4. The exhaust hole 11 of the pneumatic motor is connected with the small boiler 13. The small boiler 13 is connected with the small pneumatic motor 12. The internal part of the main engine pneumatic motor is sprayed with high-temperature-resistant zirconium oxide and other composite materials or is made of the same.
[0010] Working principle: when the high-pressure gas cylinder valve is opened, the high-pressure gas rushes into the combustion chamber, the fuel nozzle starts to spray oil and then ignites, the fuel and air undergo chemical reaction to generate high-pressure gas, at the same time, the main engine pneumatic motor intake hole valve is opened, the high-pressure gas rushes into the internal part of the main engine pneumatic motor to drive the rotary piston to rotate, strong torque is transmitted to the motor vehicle, the high-pressure gas is turned to the exhaust hole of the main engine pneumatic motor and is discharged into the small boiler, when the more than 1,000 degrees Celsius exhaust gas is discharged into the small boiler and is turned for several rounds, water or carbon dioxide is heated to generate high-pressure gas which rushes into the internal part of the small pneumatic motor to drive the rotary piston in the internal part of the motor to rotate to generate power, the generated power can be connected with the high-pressure gas pump and the generator, so as to reduce the burden of the main engine and to do work again.
[0011] The engine of the application does not need a transmission, the main engine pneumatic motor intake hole is connected with a silicon nitride spherical valve, the valve wrench is removed, the valve shaft is connected with the multi-pole transmission, so that the opening and closing times of the intake hole valve are controlled, the more the opening and closing times of the valve per second, the more the times of high-pressure gas rushing into the internal part of the pneumatic motor per second, the higher the engine speed is, and vice versa. When the speed is low, the torque is unchanged, because the amount of oil sprayed each time does not change, the engine will not be extinguished when the speed is low.
[0012] The engine of the application does not need a heat dissipation system, because the internal part of the main engine pneumatic motor is made of high-temperature-resistant zirconium oxide and other composite materials, such as the cylinder and the surface of the piston ring, which are self-lubricating and resistant to high temperature. The lubrication system is also not needed. These two items reduce the cost and energy loss again. The engine of the application improves the fuel conversion rate by 30% compared with the existing engine. The engine of the application has controllable speed and utilizes waste heat energy to do work. The structure of the engine is easy to understand by comparing the combustion chamber structure with the high-pressure gas source of the pneumatic motor. The engine of the application can reduce carbon emissions and pollution in actual use, which is beneficial to social development, reduces the transportation cost of enterprises and the burden of enterprises, and is beneficial to everyone.
